Preparing Bulletproof Coffee Ahead: What You Need to Know

Quick Answer

• Yes, you can make bulletproof coffee ahead of time, but it’s best consumed fresh for optimal flavor and texture.
• Refrigerating bulletproof coffee is the standard method for short-term storage.
• When reheating, do so gently to avoid separating the fats and coffee.
• The ideal storage time is typically 24-48 hours for the best quality.
• Adding butter and MCT oil can alter the texture and flavor upon reheating.
• Consider brewing fresh if you want the absolute best taste and emulsification.

Who This Is For

• Busy individuals looking to save time in their morning routine by preparing coffee in advance.
• People who enjoy the benefits of bulletproof coffee but want to simplify the preparation process.
• Anyone curious about the best practices for storing and reheating bulletproof coffee without sacrificing too much quality.

What to Check First

Brewer Type and Filter Type

Ensure your chosen brewing method and filter are compatible with making a strong, concentrated coffee base. Drip coffee makers, pour-overs, or Aeropress can all work. Paper filters are common, but metal filters allow more oils to pass through, which can be desirable for bulletproof coffee.

Water Quality and Temperature

Use filtered water for a cleaner taste. For most brewing methods, water heated to between 195°F and 205°F (90.5°C to 96°C) is optimal. Too cool, and you won’t extract enough flavor; too hot, and you risk scorching the coffee grounds.

Grind Size and Coffee Freshness

The grind size depends on your brewing method. For drip or pour-over, a medium grind is typical. For Aeropress, it can be finer. Always use freshly roasted coffee beans, ideally ground just before brewing. Stale coffee will result in a flat, uninspired base, no matter how you prepare it.

Coffee-to-Water Ratio

A common starting point for a strong coffee base is a ratio of 1:15 to 1:17 (coffee to water by weight). For example, 20 grams of coffee to 300-340 grams (or ml) of water. Adjust this to your preference for a bolder flavor that can stand up to the added fats.

Cleanliness/Descale Status

Your coffee maker and any blending equipment should be clean. Coffee oils can build up and turn rancid, affecting the taste of your brew. Regularly descale your coffee maker according to the manufacturer’s instructions to ensure optimal performance and flavor.

Step-by-Step: Brewing Your Bulletproof Coffee Base

1. Heat Your Water: Bring your filtered water to the optimal brewing temperature, typically 195°F to 205°F.

• What “good” looks like: Water is steaming but not vigorously boiling.
• Common mistake: Using boiling water, which can scorch the coffee. Avoid this by letting boiling water sit for 30-60 seconds before pouring.

2. Grind Your Beans: Grind your fresh coffee beans to the appropriate size for your brewer.

• What “good” looks like: A consistent grind with no excessive dust or large chunks.
• Common mistake: Using pre-ground coffee that’s been sitting for weeks. Grind just before brewing for the best aroma and flavor.

3. Prepare Your Brewer: Assemble your coffee maker and add the correct filter. Rinse paper filters with hot water to remove any papery taste.

• What “good” looks like: Filter is properly seated and rinsed.
• Common mistake: Not rinsing paper filters, leading to a bitter taste.

4. Add Coffee Grounds: Place the ground coffee into the filter.

• What “good” looks like: Grounds are evenly distributed in the filter basket or cone.
• Common mistake: Tamping down the grounds too hard, which can lead to over-extraction and bitterness.

5. Bloom the Coffee (Optional but Recommended): Pour just enough hot water to saturate the grounds and let it sit for 30 seconds.

• What “good” looks like: Grounds expand and release CO2, creating a bubbly surface.
• Common mistake: Skipping the bloom, which can result in uneven extraction and a less flavorful cup.

6. Begin Brewing: Slowly pour the remaining hot water over the grounds in a steady, circular motion. Aim for an even saturation.

• What “good” looks like: A consistent flow of coffee dripping into your carafe or mug.
• Common mistake: Pouring too quickly or unevenly, leading to channeling and under-extraction.

7. Complete the Brew: Allow all the water to pass through the grounds.

• What “good” looks like: The brewing process finishes within the expected time frame for your method (e.g., 3-5 minutes for pour-over).
• Common mistake: Removing the brewer too early or letting it drip excessively, affecting the final concentration.

8. Cool the Coffee: Let the brewed coffee cool down significantly before adding fats. This helps with emulsification later.

• What “good” looks like: Coffee is warm to the touch but not piping hot.
• Common mistake: Adding butter and oil to scalding hot coffee, which can hinder proper blending.

9. Add Fats: Measure your unsalted butter (or ghee) and MCT oil (or coconut oil). A common starting point is 1-2 tablespoons of butter and 1-2 tablespoons of MCT oil per 8-12 oz of coffee.

• What “good” looks like: Fats are measured accurately.
• Common mistake: Over-adding fats, which can make the coffee greasy and difficult to digest.

For the best results, use high-quality unsalted grass-fed butter. You can find excellent options like this one to ensure a rich flavor and smooth texture.

10. Blend Thoroughly: Pour the cooled coffee, butter, and MCT oil into a blender. Blend on high speed for 20-30 seconds.

• What “good” looks like: A frothy, creamy, emulsified beverage with no visible oil separation.
• Common mistake: Not blending long enough, resulting in a separated, oily drink.

11. Portion and Store (if making ahead): Pour the blended bulletproof coffee into an airtight container or individual jars.

• What “good” looks like: Container is clean and sealed tightly.
• Common mistake: Storing in an open container, which can lead to absorption of odors and faster spoilage.

12. Refrigerate: Allow the coffee to cool completely before refrigerating.

• What “good” looks like: Coffee is chilled and ready for storage.
• Common mistake: Putting hot liquid directly into the refrigerator, which can raise the internal temperature and affect other foods.

Common Mistakes (and What Happens If You Ignore Them)

Decision Rules for Bulletproof Coffee Prep

• If you are short on time in the morning, then you can make bulletproof coffee ahead of time because it allows for batch preparation.
• If you want the best possible emulsification and flavor, then brew your coffee fresh and blend immediately because the fats are most stable when freshly mixed.
• If you are storing bulletproof coffee for more than 48 hours, then it’s likely past its prime for optimal taste and texture because fats can oxidize and become rancid.
• If you notice oil separation after reheating, then you likely reheated it too quickly or too high because aggressive heating breaks down the emulsification.
• If your bulletproof coffee tastes off or rancid, then discard it because the fats have likely spoiled, making it unsafe or unpleasant to consume.
• If you are sensitive to digestive upset, then start with smaller amounts of MCT oil and gradually increase because a large initial dose can cause discomfort.
• If you want to preserve the creamy texture, then store it in an airtight container in the refrigerator because this slows down oxidation and spoilage.
• If you are reheating a batch, then consider blending it again briefly after heating because this can help re-emulsify the fats.
• If you are brewing a large batch to last a few days, then consider brewing a slightly stronger coffee base because the flavor can mellow slightly during storage.
• If you are concerned about fat separation, then use ghee instead of butter because ghee has a higher smoke point and can sometimes be more stable when reheated.
• If you want to avoid a papery taste, then always rinse your paper filters with hot water before adding coffee grounds because this removes any residual paper flavor.
• If you are unsure about your water’s quality, then use a water filter because it can significantly improve the taste of your coffee.

FAQ

Can I make bulletproof coffee the night before?

Yes, you can make bulletproof coffee the night before. Brew your coffee, let it cool, add your fats, blend, and then store it in an airtight container in the refrigerator. It’s best consumed within 24-48 hours.

How long does bulletproof coffee last in the fridge?

For the best quality and taste, aim to consume bulletproof coffee within 24 to 48 hours of making it. Beyond that, the fats may begin to oxidize, affecting the flavor and texture.

What happens if I don’t blend bulletproof coffee long enough?

If you don’t blend for long enough, the butter and MCT oil won’t fully emulsify with the coffee. This results in a separated drink with an oily layer on top and a watery layer at the bottom, which can be unappealing.

Is it okay to reheat bulletproof coffee in the microwave?

Yes, you can reheat bulletproof coffee in the microwave, but do so gently. Use a lower power setting and stir frequently to prevent the fats from separating. Overheating can break down the emulsification.

Can I freeze bulletproof coffee?

While technically possible, freezing bulletproof coffee is generally not recommended. The texture and emulsification can be significantly compromised upon thawing, often resulting in a greasy and unappetizing beverage.

Does the type of coffee matter for making it ahead?

Yes, the type and quality of coffee beans are crucial. Using fresh, high-quality beans that are ground just before brewing will give you a better base flavor that holds up better, even when made ahead.

What’s the best way to store pre-made bulletproof coffee?

Store it in an airtight container in the refrigerator. This helps to slow down the oxidation of the fats and preserve the flavor and texture for as long as possible.

Will the taste change if I make bulletproof coffee ahead?

The taste can change slightly. The fresh, vibrant notes of the coffee might mellow, and the emulsification might not be as perfect as when freshly blended. However, with proper storage and gentle reheating, it can still be quite enjoyable.
