What to check first
Brewer type and filter type
Your coffee maker matters. Drip machines are common, but French presses or Aeropress can give you a richer base. Paper filters can remove some oils, so consider a metal filter if you want maximum richness. Just make sure your filter is clean.
Water quality and temperature
Tap water can mess with flavor. Filtered water is best. You want your water hot, but not boiling. Aim for 195-205°F. Too cool and you won’t extract enough flavor. Too hot and you can scorch the grounds.
Grind size and coffee freshness
Freshly ground beans make a world of difference. Coarse for French press, medium for drip. Fine grind can lead to over-extraction and bitterness. Use beans roasted within the last few weeks. Older beans lose their punch.
Coffee-to-water ratio
This is key for a strong base. For bullet coffee, you want it concentrated. Try a 1:15 ratio (grams of coffee to grams of water). So, for 30 grams of coffee, use 450 grams (about 16 oz) of water. You can adjust this to your taste.
Cleanliness/descale status
A dirty brewer is a flavor killer. Make sure your machine is clean. If you have hard water, descale it regularly. Mineral buildup affects taste and performance. Nobody wants gritty, off-tasting coffee.
Step-by-step (brew workflow)
1. Select your coffee beans.
- What to do: Choose high-quality, low-mycotoxin coffee beans. Look for beans specifically tested for mycotoxins if that’s a concern.
- What “good” looks like: Beans that smell fresh and robust.
- Common mistake: Using stale or low-quality beans. This is the foundation, so don’t skimp.
- Avoid it: Buy from reputable roasters and check the roast date.

2. Grind your beans.
- What to do: Grind your beans just before brewing. Use a burr grinder for a consistent grind size appropriate for your brewer.
- What “good” looks like: Uniformly sized grounds.
- Common mistake: Using a blade grinder, which creates uneven particles and can lead to bitter coffee.
- Avoid it: Invest in a decent burr grinder. It’s worth it.
3. Heat your water.
- What to do: Heat filtered water to 195-205°F.
- What “good” looks like: Water that’s steaming but not vigorously boiling.
- Common mistake: Using boiling water, which can burn the coffee grounds.
- Avoid it: Let boiling water sit for about 30 seconds before pouring, or use a temperature-controlled kettle.
4. Brew your coffee.
- What to do: Brew a strong batch of coffee using your preferred method (drip, French press, etc.). Aim for a concentrated brew.
- What “good” looks like: A rich, aromatic coffee base.
- Common mistake: Brewing weak coffee. You need a strong foundation for the butter and oil.
- Avoid it: Use a higher coffee-to-water ratio, like 1:15.
5. Measure your ingredients.
- What to do: Measure out your grass-fed unsalted butter and MCT oil. Start small. A tablespoon of butter and a teaspoon of MCT oil is a good starting point.
- What “good” looks like: Precisely measured ingredients ready to go.
- Common mistake: Adding too much butter or oil at once. This can make it greasy or hard to digest.
- Avoid it: Measure carefully and increase gradually over time.
Measure out your grass-fed unsalted butter and MCT oil. Starting with a quality grass-fed unsalted butter like this option is key for the best flavor and nutritional profile.

6. Transfer to blender.

- What “good” looks like: All ingredients in the blender, ready for emulsification.
- Common mistake: Forgetting to add one of the ingredients.
- Avoid it: Double-check before you hit the blend button.
7. Blend until emulsified.
- What to do: Blend on high speed for 20-30 seconds. You want it to look frothy and creamy, not separated.
- What “good” looks like: A smooth, latte-like consistency with no visible oil slick.
- Common mistake: Not blending long enough, resulting in oily separation.
- Avoid it: Use a powerful blender and blend for the full recommended time.
8. Pour and enjoy.

- What “good” looks like: A warm, creamy, delicious beverage.
- Common mistake: Letting it sit too long. It will separate.
- Avoid it: Drink it right away for the best texture and taste.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using stale or low-quality coffee | Weak flavor, bitter taste, lack of energy boost | Use freshly roasted, high-quality beans. |
| Incorrect grind size | Over-extraction (bitter) or under-extraction (sour) | Use a burr grinder and match grind to brewer type. |
| Water temperature too low | Under-extraction, weak and sour coffee | Heat water to 195-205°F. |
| Water temperature too high | Scorched grounds, bitter taste | Let boiling water cool slightly or use a temp-controlled kettle. |
| Not brewing coffee strong enough | Diluted final product, not rich enough | Use a higher coffee-to-water ratio (e.g., 1:15). |
| Adding too much butter/oil initially | Greasy texture, digestive upset | Start with small amounts and gradually increase. |
| Not blending long enough | Oil and coffee separate, unappetizing texture | Blend on high speed for 20-30 seconds. |
| Using a weak blender | Incomplete emulsification, gritty texture | Use a high-powered blender. |
| Using regular butter or low-quality oil | Off-flavors, less ideal nutritional profile | Use grass-fed unsalted butter and pure MCT oil. |
| Letting it sit after blending | Separation, loss of creamy texture | Drink immediately after blending. |
Decision rules (simple if/then)
- If your coffee tastes bitter, then reduce the grind size slightly or brew for less time, because fine-tuning extraction is key.
- If your coffee tastes sour, then increase the grind size slightly or brew for longer, because under-extraction needs more contact time or coarser grounds.
- If your bullet coffee separates quickly, then blend for longer or use a more powerful blender, because emulsification is crucial.
- If you feel sluggish after drinking it, then reduce the amount of MCT oil, because some people are sensitive to large doses.
- If the texture is too thin, then try a slightly higher coffee-to-water ratio or a bit more butter, because richness comes from concentration and fat.
- If you experience digestive discomfort, then start with less butter and MCT oil, because your gut needs to adjust to the fats.
- If your coffee tastes “off” or stale, then check your bean freshness and water quality, because these are foundational to good coffee.
- If you’re looking for maximum creaminess, then consider using a metal filter with your brewer, because paper filters can remove some oils.
- If your blender struggles, then let the coffee cool slightly before blending, because very hot liquids can be harder to blend smoothly.
- If you want to experiment with flavor, then add a pinch of cinnamon or vanilla extract after blending, because subtle additions can enhance the experience.
FAQ
What kind of coffee beans are best for bulletproof coffee?
Look for high-quality, low-mycotoxin beans. Many brands specifically test for these toxins. Freshly roasted beans are also crucial for flavor.
How much butter and MCT oil should I use?
Start with 1 tablespoon of grass-fed unsalted butter and 1 teaspoon of MCT oil. You can gradually increase these amounts as you get used to it.
Can I use regular butter?
It’s recommended to use grass-fed unsalted butter for the best flavor and nutritional profile, as it contains more beneficial fatty acids. Regular butter will work but might alter the taste slightly.
What happens if I don’t blend it long enough?
If you don’t blend for at least 20-30 seconds on high speed, the butter and oil won’t fully emulsify with the coffee. This results in a separated, oily layer on top and a less creamy texture.
Is bulletproof coffee healthy?
Bulletproof coffee is high in fat and calories, designed to provide sustained energy. Its health benefits are debated and depend on your individual diet and goals. It’s not a replacement for a balanced meal.
Can I make bulletproof coffee ahead of time?
No, it’s best consumed immediately after blending. The emulsification breaks down over time, causing the fats to separate from the coffee.
What’s the deal with MCT oil?
MCT (medium-chain triglyceride) oil is a type of fat that’s easily digested and quickly converted to energy by the body. It’s believed to offer cognitive and energy benefits.
How do I avoid a greasy texture?
Ensure you’re using a good ratio of coffee to fat and blending thoroughly. If it’s still too greasy, try reducing the amount of butter or oil, or increasing the coffee volume.
