What to check first
Brewer type and filter type
Your coffee maker is the starting point. Drip, pour-over, French press – they all work. Just make sure you’re using a filter if your brewer calls for one. A clean filter means a cleaner taste. Nobody wants coffee grounds in their butter.
Water quality and temperature
Good coffee starts with good water. If your tap water tastes funky, your coffee will too. Filtered water is your friend here. Aim for water that’s hot enough to brew your coffee properly, usually between 195-205°F. Too cool and you get weak coffee; too hot and you can scorch the grounds.
Grind size and coffee freshness
Freshly ground beans are the MVP. Pre-ground stuff loses its punch fast. For drip or pour-over, a medium grind is usually the sweet spot. French press needs coarser grounds. Store your beans in an airtight container, away from light and heat.
Coffee-to-water ratio
This is key for flavor. A good starting point is about 1:15 to 1:17. That means for every gram of coffee, use 15-17 grams of water. Or, roughly 2 tablespoons of coffee per 6 oz of water. Adjust to your taste, but don’t go wild.
Cleanliness/descale status
A dirty brewer is a flavor killer. Make sure your coffee maker is clean. If you’ve got hard water, scale can build up. Descale it according to the manufacturer’s instructions. A clean machine makes clean coffee.
Step-by-step (brew workflow)
1. Brew your coffee.
- What “good” looks like: A hot, flavorful cup of coffee brewed to your liking.
- Common mistake: Using stale beans or water that’s not hot enough. Avoid this by using fresh beans and checking your water temp.
2. Prepare your ingredients.
- What “good” looks like: Your coffee is brewed, and you have your butter and MCT oil ready to go.
- Common mistake: Forgetting an ingredient or having them at the wrong temperature. Have everything within reach before you start.
3. Pour coffee into your mug.
- What “good” looks like: A mug filled with hot coffee, leaving enough room for the frothing action.
- Common mistake: Overfilling the mug. You need space for the frother to work its magic without overflow.
4. Add butter and MCT oil.
- What “good” looks like: The specified amount of unsalted butter (or ghee) and MCT oil added to the hot coffee.
- Common mistake: Adding too much. Start with a tablespoon of butter and a teaspoon of MCT oil and adjust from there. Too much can make it greasy.
For the best results, consider using a high-quality unsalted butter or ghee, which can significantly impact the flavor and creaminess of your bulletproof coffee.
- UNSALTED BUTTER: Each package comes with 4 sticks of Vital Farms Unsalted Butter made with cream from cows raised on family farms.
- 90% GRASS-FED: The girls enjoy a diet of 90% grass, while the remaining 10% is nutritionally balanced feed to ensure a well-rounded diet.
- PASTURE-RAISED: The farmers we work with raise their four-legged ladies with care and respect on family farms where cows enjoy outdoor access 200 days per year on average.
- HIGH BUTTERFAT: The girls supply a rich cream that’s churned into creamy, melt-in-your mouth butter
- CONSCIOUS CAPITALISM: Vital Farms is a Certified B Corporation with a purpose to improve the lives of people, animals, and the planet through food.
5. Insert the milk frother.
- What “good” looks like: The frothing wand is submerged in the coffee mixture, but not touching the bottom of the mug.
- Common mistake: Not submerging the frother enough. This can cause splashing and won’t create a good vortex.
A good coffee frother wand is essential for achieving that perfect creamy texture. Look for one that’s easy to handle and clean for daily use.

6. Start frothing.
- What “good” looks like: A creamy, emulsified mixture with a nice froth on top.
- Common mistake: Holding the frother still. Move it up and down gently to incorporate all the ingredients.
7. Froth for 20-30 seconds.
- What “good” looks like: The butter and oil are fully blended, creating a smooth, latte-like consistency.
- Common mistake: Frothing for too short or too long. Too short means separation; too long can make it too airy.
8. Remove the frother.
- What “good” looks like: The frother is cleanly removed from the mug.
- Common mistake: Yanking it out too fast, causing drips. Lift it slowly.
9. Serve immediately.
- What “good” looks like: A hot, creamy, delicious cup of bulletproof coffee ready to drink.
- Common mistake: Letting it sit too long. The emulsification won’t last forever.
10. Clean the frother.
- What “good” looks like: The frother is rinsed and wiped clean, ready for next time.
- Common mistake: Letting it dry with residue. Clean it right away to prevent buildup. This is crucial!
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using stale coffee beans | Weak, bitter, or flat flavor | Use freshly roasted and ground beans. |
| Water not hot enough | Under-extracted coffee, weak flavor | Ensure water is 195-205°F before brewing. |
| Using tap water with off-flavors | Unpleasant taste in your final coffee | Use filtered or bottled water. |
| Incorrect grind size | Over-extraction (bitter) or under-extraction (weak) | Match grind size to your brewing method (e.g., coarse for French press). |
| Too much butter or MCT oil | Greasy texture, digestive upset | Start with recommended amounts (e.g., 1 tbsp butter, 1 tsp MCT oil) and adjust. |
| Not enough frothing time | Ingredients separate, oily layer on top | Froth for at least 20-30 seconds until emulsified. |
| Overfilling the mug | Messy overflow during frothing | Leave ample space in the mug for aeration. |
| Not cleaning the frother immediately | Dried-on residue, difficult to clean, potential odor | Rinse and wipe the frother wand right after use. |
| Using a cold coffee base | Ingredients won’t emulsify properly | Always start with hot, freshly brewed coffee. |
| Adding ingredients before brewing | Can affect brew quality or damage brewer | Brew coffee first, then add butter and oil to the mug. |
Decision rules (simple if/then)
- If your coffee tastes bitter, then try a coarser grind or less brewing time because over-extraction makes coffee taste bitter.
- If your coffee tastes weak, then try a finer grind or more coffee grounds because under-extraction leads to a weak brew.
- If you experience separation in your bulletproof coffee, then froth for a bit longer because insufficient emulsification is the cause.
- If your bulletproof coffee has an oily sheen, then you likely used too much butter or MCT oil because excess fat won’t fully blend.
- If your milk frother isn’t creating much froth, then check if the battery is low or if the wand is clean because power and cleanliness are essential for performance.
- If your brewed coffee has sediment, then check your filter or brew method because sediment means grounds are getting through.
- If you get digestive discomfort after drinking bulletproof coffee, then reduce the amount of MCT oil because it can be potent for some.
- If your frother seems clogged, then clean it thoroughly with warm water and soap because dried residue is the usual culprit.
- If your coffee tastes “off,” then check your water quality first because bad water makes bad coffee.
- If you want a creamier texture without as much foam, then try frothing for a shorter duration, focusing on emulsification rather than air incorporation.
FAQ
Can I use a regular blender instead of a milk frother?
Absolutely. A blender will give you a very smooth, emulsified result, often even creamier than a frother. Just add your hot coffee, butter, and MCT oil to the blender and blend until smooth.
How much butter and MCT oil should I use?
Start small. A common ratio is 1 tablespoon of unsalted butter (or ghee) and 1 teaspoon of MCT oil per 8-10 oz of coffee. You can adjust this to your taste and tolerance.
What kind of milk frother works best?
Most handheld electric milk frothers will do the job. The battery-powered ones are super convenient. Just make sure it’s powerful enough to create a good vortex.
Can I use cold brew coffee for bulletproof coffee?
While you can, it’s generally not recommended. Bulletproof coffee relies on the heat of the coffee to properly emulsify the fats. Cold brew might not blend as smoothly and won’t be hot.
Is bulletproof coffee healthy?
That’s a complex question with ongoing debate. It can be a source of energy and may help with satiety for some people. However, it’s high in fat and calories, so moderation is key, and it’s not a complete meal replacement.
What happens if I don’t clean my frother?
You’ll get dried-on coffee and fat residue that becomes really hard to remove. It can also lead to an unpleasant smell or taste in your next batch. Clean it right away!
Can I add other things to my bulletproof coffee?
Sure, but be mindful. Some people add a touch of cinnamon or vanilla. Avoid adding sugar or dairy milk if you’re following the strict bulletproof protocol, as that defeats the purpose.
Will a milk frother make my coffee taste like milk?
No. A milk frother is just a tool to emulsify ingredients. It doesn’t add flavor itself. You’ll just get your coffee, butter, and MCT oil blended into a creamy consistency.
