What to check first

Brewer type and filter type

Your brewing method matters. A pour-over, French press, or even a good drip machine can work. Make sure you’re using the right filter for your brewer. Paper filters catch more oils, while metal or cloth filters let more through. This can affect the texture and richness of your fat bomb coffee.

Water quality and temperature

Coffee is mostly water, so good water equals good coffee. Tap water can have off-flavors. Use filtered water if you can. For fat bomb coffee, aim for water that’s just off the boil, around 195-205°F. Too hot can scorch the grounds; too cool won’t extract properly.

Grind size and coffee freshness

Freshly ground coffee is key. Pre-ground stuff loses flavor fast. The grind size depends on your brewer. Coarse for French press, medium for drip, finer for espresso. Using old beans is like trying to build a house with rotten wood.

Coffee-to-water ratio

This is your flavor foundation. A common starting point is a 1:15 to 1:18 ratio (coffee to water by weight). For example, 20 grams of coffee to 300-360 grams of water. Too little coffee, and it’ll be weak. Too much, and it can be bitter.

Cleanliness/descale status

Your brewer needs to be clean. Old coffee oils go rancid and ruin the taste. If you have a drip machine, descale it regularly according to the manufacturer’s instructions. A clean machine makes a clean cup, plain and simple.

Step-by-step (brew workflow)

1. Select your coffee beans.

• What to do: Choose fresh, whole coffee beans. Medium to dark roasts often pair well with fats.
• What “good” looks like: Beans that smell rich and aromatic, not stale or dusty.
• Common mistake: Using old, stale beans.
• Avoid it by: Checking the roast date on the bag. Aim for beans roasted within the last month.

2. Heat your water.

• What to do: Heat filtered water to between 195°F and 205°F.
• What “good” looks like: Water that’s hot but not violently boiling. A gooseneck kettle gives you control.
• Common mistake: Using boiling water or water that’s too cool.
• Avoid it by: Using a thermometer or letting boiling water sit for about 30-60 seconds.

3. Weigh your coffee beans.

• What to do: Measure your whole beans by weight. A good starting point is about 20 grams for a single serving.
• What “good” looks like: Precision. Using a scale ensures consistency.
• Common mistake: Guessing the amount of coffee.
• Avoid it by: Investing in a simple digital kitchen scale. It’s a game-changer for coffee.

4. Grind your coffee beans.

• What to do: Grind the weighed beans to the appropriate size for your brewer.
• What “good” looks like: A consistent grind size. Burr grinders are best for this.
• Common mistake: Using a blade grinder, which creates uneven particle sizes.
• Avoid it by: Using a burr grinder or pre-ground coffee if you absolutely must, but fresh is always better.

5. Prepare your brewer.

• What to do: Rinse your filter (if using paper) and preheat your brewer and mug.
• What “good” looks like: A clean setup ready to go. Rinsing paper filters removes papery taste.
• Common mistake: Not rinsing paper filters or using a dirty brewer.
• Avoid it by: A quick rinse with hot water for paper filters and a quick scrub for your brewer.

6. Add grounds and bloom.

• What to do: Add your ground coffee to the brewer. Pour just enough hot water to saturate the grounds (about double the weight of the coffee). Let it sit for 30 seconds.
• What “good” looks like: The grounds expand and release CO2 – this is the “bloom.”
• Common mistake: Skipping the bloom or pouring too much water initially.
• Avoid it by: Being patient and observing the bloom. It means your coffee is fresh.

7. Brew the coffee.

• What to do: Slowly pour the remaining hot water over the grounds, using your preferred method (e.g., slow, circular pour for pour-over).
• What “good” looks like: Even extraction. The brewing process should take a few minutes.
• Common mistake: Pouring too fast or unevenly, leading to under or over-extraction.
• Avoid it by: Pouring steadily and controlling the water flow.

8. Transfer brewed coffee.

• What to do: Once brewing is complete, pour the coffee into your blender.
• What “good” looks like: A clean pour without grounds getting into the blender.
• Common mistake: Leaving coffee in the brewer too long, which can lead to bitterness.
• Avoid it by: Promptly moving the brewed coffee to your blending vessel.

9. Add your fats.

• What to do: Add your chosen healthy fats to the blender with the coffee. Common additions include unsalted grass-fed butter, ghee, or MCT oil. Start with 1-2 tablespoons of butter and 1 tablespoon of MCT oil as a baseline.
• What “good” looks like: A balanced amount of fat that complements the coffee flavor.
• Common mistake: Adding too much fat, making it greasy.
• Avoid it by: Starting with smaller amounts and adjusting to your taste and goals.

10. Blend until frothy.

• What to do: Secure the lid on your blender and blend on high speed for 30-60 seconds.
• What “good” looks like: A smooth, emulsified beverage with a creamy, frothy top, like a latte.
• Common mistake: Not blending long enough, resulting in a separated or oily drink.
• Avoid it by: Blending until you achieve that desirable creamy texture.

11. Taste and adjust.

• What to do: Pour into your favorite mug, taste, and adjust ingredients if needed. You might want more fat, a touch of sweetener, or even a pinch of cinnamon.
• What “good” looks like: A delicious, satisfying drink that meets your flavor preferences.
• Common mistake: Not tasting and adjusting, leading to a less-than-perfect final product.
• Avoid it by: Being willing to tweak the recipe until it’s just right for you.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale or old coffee beans	Weak flavor, lack of aroma, bitter or flat taste.	Use freshly roasted beans (check the roast date) and store them in an airtight container away from light and heat. Grind just before brewing.
Incorrect grind size	Under-extraction (sour, weak) or over-extraction (bitter, harsh).	Match grind size to your brewing method. Coarse for French press, medium for drip, fine for espresso. A burr grinder provides consistency.
Water too hot or too cold	Scorched taste (too hot) or weak, underdeveloped flavor (too cold).	Aim for 195-205°F. Use a thermometer or let boiling water sit for 30-60 seconds.
Inaccurate coffee-to-water ratio	Coffee is too weak or too strong/bitter.	Use a kitchen scale to weigh both your coffee and water. A 1:15 to 1:18 ratio is a good starting point.
Dirty brewing equipment	Rancid, oily flavors that ruin the coffee’s taste.	Clean your brewer, grinder, and any accessories regularly. Descale automatic machines as recommended.
Skipping the bloom	Uneven extraction, gassy coffee, less complex flavor.	Pour a small amount of hot water over the grounds to saturate them, let it sit for 30 seconds to release CO2. This allows for better extraction.
Not blending long enough	Separated fats, oily texture, not frothy or creamy.	Blend for at least 30-60 seconds on high speed until the fats are fully emulsified and the coffee is smooth and frothy.
Using low-quality fats	Unpleasant taste, digestive issues, less beneficial impact.	Opt for high-quality, grass-fed butter, ghee, or pure MCT oil. Avoid margarines or highly processed fats.
Adding fats before brewing	Can interfere with extraction, leading to a less flavorful coffee base.	Brew your coffee first, then add the fats to the brewed coffee for blending. This ensures optimal extraction of coffee flavors.
Over-reliance on sweeteners	Masks the actual flavor of the coffee and fats, adds unwanted calories.	Taste the coffee and fats first. Use natural, low-carb sweeteners sparingly if needed. Focus on the quality of ingredients for flavor.
Using tap water with strong flavors	Off-flavors in your final drink that detract from the coffee and fats.	Use filtered or bottled water. This simple change can significantly improve the taste of your coffee.

Decision rules (simple if/then)

• If your coffee tastes sour, then your grind might be too coarse or your water too cool because under-extraction is happening. Try a finer grind or hotter water.
• If your coffee tastes bitter, then your grind might be too fine or your water too hot because over-extraction is happening. Try a coarser grind or slightly cooler water.
• If your fat bomb coffee is oily and separated, then you didn’t blend it long enough because the fats weren’t emulsified. Blend for another 30 seconds.
• If your fat bomb coffee tastes bland, then you might need more coffee or less water because your ratio is off. Adjust your coffee-to-water ratio.
• If your fat bomb coffee has a “papery” taste, then you likely didn’t rinse your paper filter. Always rinse paper filters with hot water before adding grounds.
• If your brewed coffee smells stale, then your beans are likely old. Use freshly roasted beans and grind them right before brewing.
• If your fat bomb coffee feels too heavy or greasy, then you might have added too much fat. Reduce the amount of butter or MCT oil next time.
• If you’re new to fat bomb coffee, then start with a standard recipe (e.g., 12 oz coffee, 1-2 tbsp butter, 1 tbsp MCT oil) and adjust from there because it’s easier to add than to take away.
• If you notice sediment in your cup from a French press, then your grind might be too fine or you pressed the plunger too hard. Use a coarser grind and press gently.
• If your automatic drip machine is brewing slowly or tasting off, then it likely needs descaling. Follow your machine’s manual for descaling instructions.

FAQ

What is fat bomb coffee?
