What to check first
Brewer type and filter type
You’re going for a French press here. It’s the easiest way to get that frothy texture without a blender. If you’re using something else, like a drip machine, you’ll likely end up with oily coffee, not emulsified butter coffee. The metal filter on a French press is key.
Water quality and temperature
Use filtered water. Tap water can have off-flavors that mess with your coffee. Aim for water just off the boil, around 195-205°F (90-96°C). Too hot, and you’ll scorch the grounds. Too cool, and you won’t extract enough flavor.
Grind size and coffee freshness
Medium-coarse is your friend for a French press. Too fine, and you’ll get sludge in your cup. Too coarse, and it’ll be weak. Freshly ground beans are best. Seriously, it makes a huge difference.
Coffee-to-water ratio
A good starting point is a 1:15 to 1:17 ratio. That means for every gram of coffee, use 15 to 17 grams of water. For a standard 12oz mug, that’s roughly 2 tablespoons of coffee to 6-7oz of water. Adjust to your taste, but don’t go crazy with the coffee.
Cleanliness/descale status
Make sure your French press is spotless. Old coffee oils can turn rancid and ruin your brew. If you use a drip machine, ensure it’s descaled. A clean machine makes clean coffee.
Step-by-step (brew workflow)
1. Heat your water. Get it to that sweet spot between 195-205°F.
- What good looks like: Water is steaming, not violently bubbling.
- Common mistake: Boiling water directly on the grounds. Avoid this by letting it sit for 30 seconds after it boils.
2. Grind your coffee. Medium-coarse, remember?
- What good looks like: Grinds are consistent, like coarse sand.
- Common mistake: Using pre-ground coffee that’s too fine for a French press. Invest in a burr grinder.
3. Add coffee to the French press. Measure it out.
- What good looks like: The correct amount of coffee in the bottom of the carafe.
- Common mistake: Eyeballing it. Use a scale or a reliable tablespoon measure.
4. Bloom the coffee. Pour just enough hot water to saturate the grounds. Let it sit for 30 seconds.
- What good looks like: The grounds puff up and release CO2.
- Common mistake: Skipping this step. Blooming releases gases for better flavor extraction.
5. Add the rest of the water. Pour evenly over the grounds.
- What good looks like: All grounds are submerged.
- Common mistake: Pouring too fast and creating a whirlpool that unevenly saturates the coffee.
6. Steep. Place the lid on, but don’t press down yet. Let it brew for 4 minutes.
- What good looks like: Coffee is steeping undisturbed.
- Common mistake: Pressing the plunger too early or too late. Stick to the 4 minutes for a balanced brew.
7. Press the plunger. Slowly and steadily push it all the way down.
- What good looks like: A smooth, even press with little resistance.
- Common mistake: Forcing the plunger down. This can push grounds through the filter and make your coffee gritty.
8. Add your fat. Pour the brewed coffee into a separate mug. Add your unsalted butter (grass-fed is nice) and MCT oil or coconut oil.
- What good looks like: The fats are in the mug, ready to be mixed.
- Common mistake: Adding fats to the French press itself. You won’t emulsify them there.
When adding your fat, consider using a high-quality grass-fed butter for optimal flavor and nutrients, like this popular option.
- KERRYGOLD PURE IRISH SALTED BUTTER: Our European-style salted butter is made on family farms from the milk of grass-fed cows, who graze year round on lush Irish pastures, for a golden yellow butter that's rich & creamy.
- ALL-NATURAL, ALL-PURPOSE: Kerrygold Salted Butter is a great all-purpose, all-natural butter. Keep a block in your butter dish to spread on fresh bread, or enhance the flavor of your baking & cooking.
- KERRYGOLD BUTTER: Made from the milk of grass-fed cows, our pure Irish butter is rich and soft. From salted butter to unsalted, garlic and herb to reduced fat, Kerrygold butter elevates your dishes.
- MORE THAN BUTTER: Beloved for our richly flavorful butter, we put the same care and quality into our all-natural cheese, like our classic Dubliner, aged cheddar, Swiss, and Blarney Castle cheese.
- TASTE THE DIFFERENCE: Kerrygold butter & cheese are made with milk from grass-fed cows not treated with rBST or other growth hormones* & raised on Irish family dairy farms. This all-natural milk is what makes our products so flavorful & creamy.
9. Whisk or frother. Use an immersion blender, milk frother, or a whisk to emulsify the fats into the coffee.
- What good looks like: The coffee has a creamy, opaque appearance, like a latte.
- Common mistake: Not whisking enough. You’ll end up with an oily layer on top.
10. Serve immediately. Pour back into your mug if you blended in a separate container.
- What good looks like: A hot, creamy, delicious beverage.
- Common mistake: Letting it sit too long. It’s best enjoyed fresh.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using stale coffee beans | Weak, flat, or bitter taste | Buy fresh beans and grind them just before brewing. |
| Water temperature too high | Burnt, bitter coffee | Let water sit for 30 seconds after boiling before pouring. |
| Water temperature too low | Under-extracted, sour, weak coffee | Ensure water is between 195-205°F (90-96°C). |
| Grind size too fine for French press | Gritty coffee, difficult to press | Use a medium-coarse grind, like coarse sand. |
| Not blooming the coffee | Uneven extraction, less flavor | Pour a small amount of water to wet grounds, wait 30 secs. |
| Pressing the plunger too fast/hard | Grounds in the cup, watery taste | Press slowly and steadily. |
| Not emulsifying fats properly | Oily layer on top, not creamy texture | Whisk or use a frother until fully blended and opaque. |
| Using low-quality butter/oil | Off-flavors, less palatable | Opt for grass-fed butter and quality MCT or coconut oil. |
| Not cleaning the French press | Rancid oils, off-putting taste and smell | Wash thoroughly after each use. |
| Adding fats to the French press | Inability to emulsify, oily brew | Add fats to the brewed coffee in a separate mug or container. |
| Using tap water with strong flavors | Unpleasant taste that masks coffee notes | Use filtered water for a cleaner taste. |
| Over-extraction (too long steep time) | Bitter, astringent coffee | Stick to the recommended 4-minute steep time for French press. |
Decision rules (simple if/then)
- If your coffee tastes bitter, then try a coarser grind or a slightly lower water temperature because these can reduce over-extraction.
- If your coffee tastes sour or weak, then try a finer grind or a longer steep time because these can increase extraction.
- If you have oily separation on top, then whisk or froth longer because the fats haven’t fully emulsified.
- If your French press is hard to plunge, then your grind is likely too fine or you’re pressing too fast because the grounds are creating too much resistance.
- If you want a richer, creamier texture, then add a bit more butter or MCT oil because these fats are what create that mouthfeel.
- If you’re short on time, then skip the extra fat and just brew good coffee because a well-brewed cup is still great.
- If your coffee has sediment, then make sure your filter is clean and your grind is coarse enough because these are the main culprits.
- If you want to experiment with flavor, then try adding a pinch of cinnamon or a drop of vanilla extract after emulsifying because these won’t interfere with the blending process.
- If your coffee tastes “off” or stale, then check the freshness of your beans and ensure your equipment is clean because these are the most common reasons for bad flavor.
- If you’re new to this, then start with a 1:15 coffee-to-water ratio and adjust to your preference because this is a solid baseline.
- If you want to make it cold, then brew it strong, let it cool, and then add your fats and emulsify, because hot liquid emulsifies best.
FAQ
Can I use a regular coffee maker?
You can brew coffee with a drip machine, but you won’t get the emulsified butter coffee texture. The fats will just sit on top. It’s better to use a French press for this method.
What kind of butter is best?
Grass-fed, unsalted butter is often recommended for its flavor profile and nutrient content. However, any good quality unsalted butter will work in a pinch.
How much MCT oil should I use?
Start with a tablespoon. You can increase it gradually as your body gets used to it. Too much too soon can cause digestive upset.
Does it really taste like butter?
It’s more of a rich, creamy texture than a distinct butter flavor. The coffee still shines through, but it’s smoother and more satisfying.
Can I make this ahead of time?
It’s best enjoyed fresh. The emulsification breaks down over time, and it won’t taste as good. Brew it, blend it, and drink it right away.
Is butter coffee healthy?
It can be a good option for those following a ketogenic or low-carb diet. The fats provide energy. However, it’s calorie-dense, so be mindful of your overall intake.
What if I don’t have a whisk?
A milk frother or even vigorously shaking the coffee and fats in a sealed jar works. The goal is to create a vortex to mix them thoroughly.
How much coffee should I use?
A good starting point is around 2 tablespoons for a 12oz mug. You can adjust this based on how strong you like your coffee.
Can I use decaf coffee?
Absolutely. If you want the texture and richness without the caffeine, decaf coffee works just fine.
