How to Store and Roast Coffee – A Prepper’s SHTF Guide
The most practical way to preserve coffee for an emergency is to keep instant coffee for immediate use, roasted whole beans for short-term storage, and unroasted green coffee beans for a longer-term supply. Store them in sealed, moisture-resistant containers away from heat and sunlight. With suitable equipment and a safe outdoor heat source, green beans can be roasted without electricity.
A prolonged power outage or supply disruption changes how coffee must be prepared. Electric grinders, automatic coffee makers, and household roasting machines may become unusable. Poor storage can also leave a large coffee stockpile stale or damaged before it is needed.
A layered supply provides more flexibility. Instant coffee requires almost no preparation, roasted beans can be ground manually, and green beans provide the option of roasting fresh batches when replacement supplies are unavailable.
The U.S. Centers for Disease Control and Prevention recommends storing at least 1 gallon of water per person per day for three days, with a two-week supply preferred when possible. Coffee preparation must fit within that emergency water plan rather than compete with drinking, sanitation, and cooking needs.
For me, How to Store and Roast Coffee is best approached as two connected preparedness tasks: protecting coffee before a disruption and having the equipment needed to prepare it afterward. Storing green beans alone does little good if there is no safe roasting method, grinder, or drinking water.
One detail deserves attention before buying large quantities. Green coffee remains flavorful longer than roasted coffee, but claims that ordinary beans will maintain their quality for 20 or 25 years are not supported by typical specialty-coffee storage guidance.
The storage methods, realistic freshness periods, outdoor roasting steps, manual grinding options, and emergency brewing techniques below provide a practical system for maintaining a coffee supply during power failures, extended emergencies, and other SHTF situations.
How to Store and Roast Coffee for an SHTF Emergency
A reliable emergency coffee plan should not depend entirely on one type of coffee.
Different forms have different storage advantages, preparation requirements, and limitations.
Keep Instant Coffee for Immediate Emergencies
Instant coffee is one of the simplest options for a short-term emergency.
It is made from brewed coffee that has been dehydrated through processes such as freeze-drying or spray-drying.
Commercially packaged instant coffee is shelf-stable when stored according to its instructions.
Preparation requires little more than safe drinking water and a cup. Many instant products dissolve in cold water, although warm water usually produces a more familiar drinking experience.
Instant coffee is useful during the first days of a power failure, when maintaining safe water, food, warmth, and communications takes priority over roasting beans.
Choose sealed containers or individual packets, and rotate them according to their labeled best-by dates.
Store Roasted Whole Beans for Regular Use
Roasted whole beans are a practical choice for a rotating pantry supply.
They require grinding and brewing but no additional roasting.
Whole beans generally retain desirable flavors longer than ground coffee because less surface area is exposed to oxygen.
The National Coffee Association lists approximately one to three weeks of peak freshness for roasted whole beans stored at room temperature under suitable conditions.
This is a flavor-quality guideline, not an automatic food safety expiration date.
A sealed package may retain usable coffee longer, although flavor gradually declines.
For a prepper pantry, purchase quantities that can be used and replaced regularly rather than leaving the same bag untouched for years.
Reserve Green Coffee Beans for Future Roasting
Green coffee beans are dried, unroasted coffee seeds.
They are hard, dense, and lack the familiar aroma of roasted coffee.
Because they have not undergone roasting, they retain their quality longer than ordinary roasted beans when stored correctly.
Green beans are useful for an extended disruption because small quantities can be roasted as needed.
Yet they introduce additional requirements.
You need a suitable heat source, roasting equipment, a cooling method, and a manual grinder.
I would treat green beans as a secondary reserve rather than the only coffee available during an emergency.
Key Takeaway: A layered supply is more practical than relying on green beans alone. Instant coffee covers immediate needs, roasted beans support everyday rotation, and green beans provide a future roasting option.
How Long Can Different Types of Coffee Be Stored?
Coffee shelf life depends on processing, packaging, temperature, moisture exposure, and storage conditions.
The most useful distinction is between the period of best flavor and the period during which a product remains safe to consume.
| Coffee Type | Practical Freshness Guidance | Emergency Storage Role |
| Green coffee beans | Commonly about 6–12 months of good quality with proper storage | Rotating longer-term reserve |
| Roasted whole beans | Often 1–3 weeks of peak freshness at room temperature after opening | Short-term pantry |
| Ground coffee | Often 1–2 weeks of peak freshness at room temperature after opening | Immediate convenience |
| Sealed instant coffee | Follow the manufacturer’s best-by date | Emergency reserve |
| Factory-sealed specialty survival coffee | Follow verified packaging and manufacturer storage instructions | Extended emergency storage |
These periods are not guaranteed spoilage dates.
Roasted coffee can remain usable after its best flavor has faded, provided it stays dry and free from contamination.
Unopened commercial packages may also maintain acceptable quality longer than opened containers.
Why Green Coffee Has a Storage Advantage
Roasting triggers chemical reactions that produce coffee’s recognizable flavors and aromas.
It also changes the beans’ physical structure and exposes compounds that gradually degrade through oxidation.
Green beans have not undergone those roasting changes.
Sweet Maria’s, a specialty-coffee supplier with extensive green-bean storage guidance, recommends expecting approximately six months of stable quality, with some coffees remaining attractive for up to a year.
Beyond that period, green beans may develop flat, woody, or papery flavors.
This does not mean all older green coffee becomes unsafe immediately.
It means quality can decline considerably before an obvious spoilage problem appears.
Can Coffee Really Last 25 Years?
Some emergency-food manufacturers advertise coffee products with shelf lives extending 10, 20, or 25 years.
Those claims may apply to specific commercially processed and packaged products under stated storage conditions.
They should not be applied automatically to ordinary green coffee, roasted beans, or homemade Mylar packages.
A manufacturer’s shelf-life claim should identify the product, packaging system, storage conditions, and evidence supporting the stated period.
My recommendation is to avoid building a multi-year coffee plan around an unverified storage promise.
Rotating supplies provides a more dependable approach.
Key Takeaway: Green beans generally retain quality longer than roasted coffee, while sealed instant coffee is convenient for emergency reserves. Packaging claims should not replace realistic rotation and inspection.
How to Store Green Coffee Beans for Long-Term Preparedness
Proper green-bean storage focuses on controlling moisture, temperature changes, light, and contamination.
A high-quality bag cannot compensate for beans that were already damp or damaged when packaged.
Start With Properly Dried Green Beans
Choose green coffee from a supplier that identifies the coffee’s origin, processing method, and approximate arrival or harvest information.
Commercial green coffee is commonly dried to around 10–12% moisture content before export.
This moisture range supports normal commercial storage, but it does not mean green beans are completely dry.
Excess moisture can encourage mold and reduce flavor quality.
Inspect beans before storage.
Look for unusual dampness, visible mold, severe discoloration, or a musty smell.
Do not attempt to rescue visibly moldy coffee by roasting it. Certain mold toxins can resist ordinary heat treatment.
Discard contaminated beans.
Choose Moisture-Resistant Containers
Suitable containers include:
- Clean glass jars with tight-fitting lids
- Food-grade high-barrier coffee storage bags
- Purpose-made hermetic green-coffee packaging
- Suitable food-storage containers with dependable moisture barriers
Glass provides a good barrier against external moisture and odors when properly sealed.
High-barrier bags can also reduce exposure to air and changing humidity.
Divide a large supply into smaller portions.
Opening one container repeatedly exposes the entire contents to changing air and moisture conditions.
Smaller packages let you use one portion while leaving the remaining reserve undisturbed.
Keep Green Coffee Cool, Dark, and Dry
Store coffee in a location with stable conditions.
A climate-controlled pantry or interior storage cabinet is generally better than an uninsulated shed, hot garage, or damp basement.
Avoid direct sunlight, excessive humidity, and strong odors.
Green beans can absorb surrounding smells, including those from fuel, cleaning products, and other strongly scented materials.
Keep coffee away from gasoline, pesticides, solvents, and emergency fuel containers.
Ordinary room-temperature storage is suitable when the space remains cool and dry.
Refrigeration is usually unnecessary, and moisture changes can create condensation problems.
Should You Use Mylar Bags and Oxygen Absorbers?
Mylar-style high-barrier bags can be useful when the packaging is designed for food storage and sealed properly.
Oxygen absorbers require more caution.
Green coffee is commonly stored at moisture levels higher than those of some dry foods intended for long-term oxygen-free storage.
Adding oxygen absorbers without confirming moisture conditions and packaging suitability can create an unsafe assumption about mold prevention and shelf life.
For a home prepper supply, I prefer verified green-coffee storage packaging or clean airtight containers over an improvised oxygen-absorber system.
Do not assume that vacuum sealing or removing oxygen makes damp beans safe.
Label and Rotate Your Supply
Label each container with the coffee type, purchase date, and packaging date.
Use the oldest suitable supply first.
Inspect stored beans periodically for changes in condition.
An unusual musty odor, visible growth, or signs of water intrusion are reasons to discard the affected coffee.
If a reserve has been stored for a long period, roast a small sample and evaluate its quality before relying on the entire batch.
Key Takeaway: Green beans store best in stable, dry conditions inside suitable barrier packaging. Control moisture first, divide supplies into manageable portions, and avoid treating oxygen absorbers as a guarantee of decades-long storage.
How to Store Roasted and Instant Coffee During Emergencies
Roasted and instant coffee require less preparation than green beans, but their packaging needs differ.
Store Roasted Coffee Away From Air and Heat
Roasted coffee gradually loses flavor through exposure to oxygen, warmth, light, and moisture.
Use an opaque, airtight coffee container or a suitable high-barrier bag.
Keep it in a cool cupboard away from ovens, windows, and other heat sources.
Whole beans generally provide better short-term flavor retention than pre-ground coffee.
For emergency readiness, keep a modest supply of roasted beans alongside a manual grinder.
Use and replenish this supply during normal cooking routines.
Allow Freshly Roasted Beans to Degas
Freshly roasted coffee releases carbon dioxide in a process called degassing.
Do not immediately seal hot, newly roasted beans inside a completely airtight container.
First, cool them thoroughly.
Then use a suitable one-way-valve coffee bag, or allow controlled gas release according to the storage container’s instructions before sealing tightly.
A simple container that cannot vent should not be tightly closed while substantial gas release is still occurring.
Many coffees develop a more balanced flavor after resting for approximately 24–72 hours following roasting.
During a genuine emergency, freshly cooled coffee can be brewed sooner. The flavor may be less developed.
Keep Instant Coffee Sealed Until Needed
Moisture is a major concern for instant coffee.
Once exposed to humid air, the powder or granules can clump and deteriorate.
Store unopened packages according to their instructions.
After opening a container, close it tightly and use a clean, dry spoon.
Individual packets are convenient because opening one serving leaves the remaining stock sealed.
A good emergency supply should include instant coffee that you already find acceptable to drink.
Is Freezing Coffee Worthwhile?
Freezing properly sealed roasted coffee can slow flavor deterioration.
Yet it depends on a reliable freezer and careful moisture control.
Repeatedly opening frozen coffee packages can introduce condensation.
For a long power outage, freezer-dependent storage is not a dependable primary strategy.
If freezing coffee during normal conditions, divide it into airtight portions and allow a removed portion to reach room temperature while still sealed.
I would not make frozen beans the foundation of a prepper coffee reserve.
Key Takeaway: Keep roasted coffee in small airtight portions and rotate it frequently. Allow fresh roasts to release gas safely, and use sealed instant coffee for a backup that requires little preparation.
How to Roast Coffee Beans Without Electricity
Coffee roasting requires enough heat to transform green beans into brown, aromatic roasted coffee.
Electricity is not mandatory, but a controllable heat source and safe working area are necessary.
A manual stovetop roaster or suitable skillet can work during a power outage.
Safety Warning: Coffee roasting generates smoke, hot chaff, and a fire risk. Fuel-burning camp stoves and charcoal grills must never be used inside a house, garage, tent, or other enclosed shelter. The CDC warns that these appliances can produce deadly carbon monoxide. Roast outdoors in a suitable location, away from doors, windows, vents, and combustible materials, following equipment instructions and local fire restrictions.
Equipment Needed for Off-Grid Roasting
A basic manual setup includes:
- Green coffee beans
- A suitable metal skillet or manual stovetop coffee roaster
- An outdoor-rated cooking stove and approved fuel
- A heat-resistant stirring tool
- A metal colander or roasting cooler
- Heat-resistant gloves
- A suitable fire extinguisher
A hand-cranked stovetop popcorn roaster can provide consistent agitation when the manufacturer permits its use for coffee roasting.
A skillet is simpler, but it requires continuous attention to prevent uneven roasting.
Before an actual emergency, practice using the equipment under normal, safe conditions.
Step-by-Step Outdoor Skillet Roasting
- Prepare the roasting area. Select a stable, noncombustible outdoor surface. Set up the stove according to its instructions and keep cooling equipment nearby.
- Measure a small batch. Starting with roughly 3–4 ounces (85–115 grams) of green coffee is manageable for a beginner using a suitable skillet. Keep the beans in a shallow layer so they can move freely.
- Heat the skillet gradually. Use controlled medium heat rather than the highest burner setting. Exact settings vary with the pan, fuel source, and outdoor conditions.
- Add the green beans. Begin stirring or shaking the pan immediately. Maintain nearly continuous movement so one side of the beans does not remain against the hottest surface.
- Watch the color change. Beans usually progress from green to yellow, tan, and brown. A grassy smell gradually gives way to toasted aromas.
- Listen for first crack. The beans produce distinct popping sounds as roasting reactions develop. This stage commonly occurs when bean temperatures approach roughly 390–405°F, but pan temperature is not the same as bean temperature.
- Control the final roast. A light roast develops around first crack. Allow more controlled development for a medium roast, watching the beans closely rather than relying on a fixed number of minutes.
- Remove the beans from heat. Transfer them promptly into a heatproof metal colander or suitable cooling device once the desired roast has been reached.
- Cool the coffee. Agitate the beans to release heat and prevent continued roasting. Keep hot beans, chaff, and equipment away from combustible materials.
- Rest and store the beans. Once fully cooled, allow appropriate degassing, then transfer the coffee into a suitable container for short-term use.
Stovetop roasting often takes roughly 8–15 minutes, but the actual time varies widely.
Bean color, aroma, cracking sounds, and visible smoke provide more useful clues than the clock alone.
Never leave a roasting pan unattended.
Understanding Light, Medium, and Dark Roasts
A roast does not become better simply because the beans turn darker.
| Roast Level | General Appearance | Practical Characteristics |
| Light | Light to medium brown | More origin-specific flavors and noticeable acidity |
| Medium | Medium brown | Balanced roast flavor and sweetness |
| Dark | Dark brown, sometimes oily | Stronger roasted flavors and greater risk of smoky bitterness |
For someone roasting manually during an emergency, a controlled medium roast is often a reasonable target.
Trying to produce a very dark roast can increase smoke and the risk of scorching.
The second crack is a later roasting stage associated with darker development. The popping is often quieter and more rapid.
Stop the roast before the beans begin burning.
Why Cooling and Resting Matter
Beans continue roasting briefly after leaving the heat source.
Rapid cooling reduces unintended darkening.
Hot coffee should never be transferred directly into ordinary plastic containers that are not rated for those temperatures.
Once cool, the beans need time to release carbon dioxide.
The National Coffee Association identifies roughly two to seven days after roasting as a desirable period for enjoying freshly roasted flavors, although preferences and roast styles differ.
For emergency use, roasting small batches provides more control and reduces waste.
Key Takeaway: Off-grid roasting is possible with suitable manual equipment and an outdoor heat source. Keep the beans moving, monitor first crack, cool them promptly, and never sacrifice fire or carbon-monoxide safety for coffee.
How to Grind and Brew Coffee Without Power
Roasting solves only part of the preparation problem.
Whole roasted beans must still be ground, and brewing requires safe water.
A manual setup removes dependence on electric coffee equipment.
Grinding Coffee With Hand Tools
A manual burr grinder is a practical addition to a prepper kitchen.
It uses a hand crank to grind roasted beans and can produce different grind sizes.
Coarse grounds work well in a French press, while medium grounds suit many pour-over brewers.
If a hand grinder is unavailable, a mortar and pestle can crush roasted coffee.
The grind will be less uniform, and brewing may produce more sediment.
Do not attempt to grind green beans in a household coffee grinder. They are much harder than roasted beans and may damage the mechanism.
Roast the beans first.
Making Coffee Without an Electric Brewer
Several simple brewing methods work without electricity.
French press: Add appropriately ground coffee and hot, safe water. Steep for about four minutes as a starting point, then press gently.
Manual pour-over: Place a filter in a suitable dripper and gradually pour hot water over the grounds.
Cowboy coffee: Heat safe water in a suitable pot, remove it from strong heat, add coarse grounds, allow them to steep, and carefully pour off the beverage after the grounds settle.
Instant coffee: Mix the product with safe water according to the package directions. Some varieties dissolve in cold water.
A starting brewing ratio is approximately 15 grams of ground coffee per 8 fluid ounces (237 milliliters) of water.
Adjust the amount to taste.
Safe Water Comes Before Coffee
During an emergency, drinking water quality takes priority over brewing preferences.
The CDC recommends bringing clear water to a rolling boil for one minute, or three minutes at elevations above 6,500 feet, when boiling is needed to make microbiologically contaminated water safer.
Boiling does not remove harmful chemical or radioactive contamination.
Follow local drinking-water advisories and use an uncontaminated water source.
A normal hot-coffee brewing process should not automatically be treated as sufficient water disinfection when the water source is unsafe.
Keep enough water available for drinking, cooking, hygiene, and other urgent needs.
Key Takeaway: A manual grinder and French press or pour-over brewer make roasted coffee usable without electricity. Safe drinking water and an approved cooking method are more important than the brewing equipment.
How Much Coffee Should a Prepper Store?
The amount of coffee worth storing depends on household consumption, the desired reserve period, and the ability to rotate the supply.
A simple calculation prevents buying more coffee than can reasonably remain fresh.
Calculate Daily Coffee Consumption
Start by estimating how much ground coffee you normally use per cup.
Using 15 grams per cup as an example:
| Consumption | 30-Day Roasted Coffee Supply | Approximate Green Coffee Needed |
| 1 cup daily | 450 g (about 1 lb) | 530 g (about 1.2 lb) |
| 2 cups daily | 900 g (about 2 lb) | 1,060 g (about 2.3 lb) |
| 3 cups daily | 1,350 g (about 3 lb) | 1,590 g (about 3.5 lb) |
The green-bean estimates assume roughly 15% weight loss during roasting.
Actual weight loss varies with the beans and roast level.
The table is a planning example, not a requirement to drink a fixed quantity of coffee.
For multiple coffee drinkers, add their individual consumption.
Build a Rotating Emergency Supply
I recommend dividing the supply into three practical levels.
Keep enough instant coffee for immediate short-term disruptions.
Maintain a regularly used supply of roasted whole beans for ordinary brewing.
Store a measured green-bean reserve that can be roasted and replaced before quality deteriorates substantially.
Label containers clearly and use the oldest suitable coffee first.
A small supply that gets rotated is generally more dependable than a large stockpile that receives no inspection.
Prioritize Water, Food, and Fuel
Coffee is a comfort item during a disaster, not a replacement for essential emergency supplies.
Do not use limited drinking water or cooking fuel for coffee when those resources are needed for hydration, food preparation, medical needs, or sanitation.
Roasting beans also consumes fuel that could otherwise prepare meals.
During the first hours of an emergency, instant coffee may be the most sensible option.
A fresh-roast routine becomes more reasonable after immediate safety and household needs are covered.
Key Takeaway: Estimate coffee quantities from actual daily use, account for roasting weight loss, and rotate supplies. Emergency water and cooking fuel must take priority over coffee preparation.
Common Coffee Storage and Roasting Mistakes Preppers Should Avoid
Several assumptions can make a large coffee reserve less dependable.
Storing all coffee in one container: Repeated opening exposes the entire stockpile to moisture and oxygen. Smaller portions reduce that exposure.
Assuming green beans last indefinitely: Unroasted coffee generally retains flavor longer than roasted coffee, but age, heat, and humidity still affect quality.
Using unsuitable oxygen absorbers: Removing oxygen without understanding the coffee’s moisture condition does not guarantee safe storage.
Keeping coffee near emergency fuel: Coffee absorbs odors and should be separated from gasoline, solvents, and other chemicals.
Depending on electricity for every preparation step: A stored supply is less useful when grinding, heating, and brewing all require functioning appliances.
Roasting in an enclosed shelter: Camp stoves and charcoal produce carbon monoxide. Smoke and chaff also create fire hazards.
Sealing freshly roasted beans while hot: Heat and continuing gas release can create storage problems. Cool the beans and follow suitable degassing procedures.
Ignoring signs of mold: Musty-smelling or visibly moldy beans should be discarded rather than roasted in an attempt to make them safe.
The most dependable preparedness habit is practicing a complete coffee-making routine before electricity or normal supplies become unavailable.
Conclusion
How to Store and Roast Coffee during an emergency comes down to choosing suitable coffee forms, protecting them from moisture and heat, and preparing for the loss of electricity. Instant coffee covers immediate needs, roasted beans support regular brewing, and green beans provide a reserve that can be roasted in small batches.
Green beans should be stored in clean, suitable barrier packaging and rotated within a realistic quality period. Manual roasting requires a controlled outdoor heat source, constant attention, proper cooling, and safe storage afterward. A hand grinder and simple brewer complete the setup.
My recommendation is to keep a modest, rotating supply rather than depending on an enormous stockpile with an unverified shelf life. Practice the entire process under normal conditions, store drinking water first, and use fuel-burning equipment only in safe locations. A reliable routine matters more than having the largest collection of coffee beans.
FAQs About Storing and Roasting Coffee for SHTF
What is the best coffee to store for a long-term emergency?
A combination of commercially packaged instant coffee and properly stored green coffee beans is a practical option.
Instant coffee requires little preparation and is suitable for quick use during power failures.
Green coffee beans retain their roasting potential longer than roasted beans, but their flavor quality still declines with age.
Follow labeled storage dates, control moisture, and rotate green coffee rather than assuming ordinary beans will remain fresh for decades.
How long can green coffee beans last in Mylar bags?
Properly packaged green beans may retain acceptable quality for months and sometimes longer, but Mylar packaging alone does not establish an exact shelf life.
Sweet Maria’s recommends roughly six months of stable quality, with some beans remaining appealing for about a year under suitable conditions.
Results depend on the beans’ original moisture content, age, temperature, humidity, and packaging quality.
Do not assume that Mylar bags and oxygen absorbers guarantee 20 years of safe, flavorful coffee.
Can you roast coffee over a campfire?
Yes. Green coffee beans can be roasted using a suitable metal roasting vessel over a controllable outdoor fire.
The main difficulties are uneven heat, smoke, and the need to keep beans moving.
A suitable outdoor camp stove generally provides more predictable heat control than an open fire.
Never roast inside a tent, garage, or enclosed shelter. Keep combustible chaff away from flames, follow fire restrictions, and have appropriate fire-safety equipment available.
Can you drink green coffee beans without roasting them?
Green coffee beans are generally intended to be roasted before grinding and ordinary coffee brewing.
They are denser and harder than roasted beans, and they produce a different beverage when prepared without roasting.
Some commercial green-coffee extracts and beverages exist, but they are not equivalent to traditional roasted coffee.
For emergency coffee preparation, roast green beans using appropriate equipment before grinding them in a standard hand grinder.
Can roasted coffee be stored for several years?
Properly sealed roasted coffee may remain usable beyond its peak freshness period, but flavor deteriorates over time.
Roasting exposes compounds to processes that gradually reduce aroma and flavor quality.
Commercial products with specialized packaging may carry longer best-by dates.
Do not assume that ordinary roasted beans stored in a household jar will retain fresh-roasted flavor for several years.
For preparedness, regularly rotate roasted coffee and reserve green beans or properly packaged instant coffee for longer storage.
Do you need electricity to roast coffee beans?
No. Coffee beans can be roasted using suitable manual equipment and a controllable heat source that does not depend on electricity.
Examples include a purpose-made hand-cranked stovetop roaster or an appropriate metal skillet.
The process still requires heat, safe ventilation, supervision, and a way to cool the beans.
Fuel-burning camp stoves should be operated outdoors according to their instructions. A manual grinder is also needed if electric grinding equipment is unavailable.
Is instant coffee better than green beans for survival storage?
Instant coffee is easier to use during an immediate emergency because it does not require roasting or grinding.
Green beans offer more control over fresh roasting but require additional equipment, fuel, and preparation time.
Neither form is the universal winner.
I would store instant coffee for power outages and short disruptions while keeping a smaller green-bean reserve for situations where safe roasting and brewing remain practical.
How can I make coffee during a power outage without a grinder?
Pre-ground coffee and instant coffee are the simplest options when no grinder is available.
If you have roasted whole beans, a clean mortar and pestle can crush them into grounds, although the resulting particle sizes may be uneven.
Use a French press, manual pour-over, or another non-electric brewing method with safe water.
Avoid placing unroasted green beans in a standard household grinder. Their hardness can damage equipment, and they must be roasted for normal coffee preparation.
