How to Make Bru Coffee

Quick answer

• Grind your beans fresh, right before brewing.
• Use good water. Filtered is best.
• Get the coffee-to-water ratio dialed in.
• Make sure your brewer is clean.
• Heat your water to the right temp, usually 195-205°F.
• Experiment with grind size. It matters a lot.
• Be patient. Good coffee takes a little time.

Who this is for

• You’re new to brewing at home and want to level up your daily cup.
• You’ve got a Bru brewer (or similar) and you’re not quite getting the results you want.
• You’re tired of mediocre coffee and ready to taste the difference good technique makes.

What to check first

Brewer type and filter type

Most “Bru” style brewers are pour-over or immersion drippers. Yours might be ceramic, glass, or metal. The filter is key here. Paper filters catch more oils, giving a cleaner cup. Metal filters let oils through, for a richer flavor. Make sure your filter fits snug and doesn’t have weird flavors.

If you’re looking for a reliable pour-over setup, consider investing in a quality pour over coffee maker to enhance your brewing experience.

Water quality and temperature

Tap water can mess with your coffee’s taste. Hard water or water with chlorine? Yeah, that’s a no-go. Filtered or spring water is your best bet. For temperature, aim for 195-205°F. Too hot, you burn the coffee. Too cool, you under-extract. A kettle with a thermometer is a game-changer.

Grind size and coffee freshness

This is huge. Always grind beans right before you brew. Pre-ground coffee loses its mojo fast. For most pour-over style brewers, a medium grind is a good starting point. Think coarse sand. Freshly roasted beans, used within a few weeks of their roast date, will also make a big difference.

Coffee-to-water ratio

This is your recipe. A common starting point is 1:15 to 1:17. That means 1 gram of coffee for every 15-17 grams of water. For example, 20 grams of coffee to 300-340 grams of water. Weighing your coffee and water is the most accurate way to get consistent results.

To achieve this precision, a good coffee scale is an essential tool for consistent results.

Cleanliness/descale status

A dirty brewer is a flavor killer. Old coffee oils build up and go rancid. This makes your coffee taste bitter and stale. If you have a metal or plastic brewer, give it a good scrub regularly. If you have a machine that uses heating elements, descale it as recommended by the manufacturer. It’s usually every 1-3 months.

Step-by-step (brew workflow)

1. Heat your water.

• What “good” looks like: Water is between 195-205°F.
• Common mistake: Using boiling water straight from the kettle. This can scald the grounds. Let it sit for 30-60 seconds after boiling.

2. Prepare your filter.

• What “good” looks like: Paper filter is rinsed with hot water. This removes paper taste and preheats the brewer.
• Common mistake: Not rinsing the paper filter. You’ll get a papery taste in your coffee.

3. Grind your coffee.

• What “good” looks like: Freshly ground coffee with a consistent particle size, like coarse sand.
• Common mistake: Using pre-ground coffee or an inconsistent grind. This leads to uneven extraction and off-flavors.

4. Add coffee to the brewer.

• What “good” looks like: Coffee bed is level and even.
• Common mistake: Tapping the brewer hard to settle the grounds. This can create fines that clog the filter. Gently shake it if needed.

5. The Bloom.

• What “good” looks like: Pour just enough water (about twice the weight of the coffee) to saturate all the grounds. Let it sit for 30 seconds. You’ll see the coffee puff up and release CO2.
• Common mistake: Skipping the bloom or pouring too much water. Not blooming means you trap CO2, which can lead to sour coffee.

6. First Pour.

• What “good” looks like: Pour slowly in a circular motion, starting from the center and moving outwards. Avoid pouring directly on the filter paper.
• Common mistake: Pouring too fast or aggressively. This can create channels in the coffee bed, leading to weak spots and uneven extraction.

7. Subsequent Pours.

• What “good” looks like: Continue pouring in stages, maintaining a consistent water level and avoiding disturbing the coffee bed too much. Aim for a total brew time of 2-4 minutes, depending on your brewer and batch size.
• Common mistake: Pouring all the water at once or letting the brewer run dry between pours. This disrupts the extraction process.

8. Let it drip.

• What “good” looks like: The last drops of water finish dripping through.
• Common mistake: Letting the brewer sit with water in it after the coffee has finished dripping. This can lead to bitter flavors.

9. Serve and enjoy.

• What “good” looks like: Your coffee is ready to drink. Taste it black first to appreciate the nuances.
• Common mistake: Adding milk and sugar before tasting. You might mask subtle flavors you actually like.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes sour, then try grinding finer because finer grounds increase surface area for extraction.
• If your coffee tastes bitter, then try grinding coarser because coarser grounds reduce extraction.
• If your coffee tastes weak, then use more coffee or less water because you’re likely under-extracting.
• If your coffee tastes too strong, then use less coffee or more water because you’re likely over-extracting.
• If your coffee has a papery taste, then make sure you’re rinsing your paper filter thoroughly.
• If your brew time is too fast (under 2 minutes), then try grinding finer because a finer grind slows down the water flow.
• If your brew time is too slow (over 4 minutes), then try grinding coarser because a coarser grind speeds up the water flow.
• If you notice channeling (water finding paths through the coffee bed), then try a more even pour and avoid tapping the grounds.
• If your water tastes off, then use filtered or spring water because tap water can significantly impact flavor.
• If your coffee tastes muddy, then ensure you’re using the correct filter type for your brewer and that it’s seated properly.
• If your coffee lacks aroma, then grind your beans immediately before brewing because aroma dissipates quickly after grinding.
• If your brewed coffee has a “burnt” taste, then check your water temperature and ensure it’s not boiling hot.

FAQ

What is a “Bru Coffee”?

“Bru Coffee” likely refers to coffee brewed using a pour-over method, often in a cone-shaped dripper like a Hario V60 or Kalita Wave. It emphasizes manual control over the brewing process.

How much coffee should I use?

A good starting point is a 1:15 to 1:17 coffee-to-water ratio. For example, 20 grams of coffee to 300-340 grams (or milliliters) of water. Weighing is key for consistency.

What kind of grinder is best?

A burr grinder is highly recommended over a blade grinder. Burr grinders produce a more uniform particle size, which is crucial for even extraction and better-tasting coffee.

How hot should the water be?

Ideally, water temperature should be between 195°F and 205°F. This range is hot enough to extract the coffee’s flavors efficiently without burning them.

Can I reuse coffee grounds?

No, you cannot reuse coffee grounds. Once brewed, the soluble compounds that give coffee its flavor have been extracted. Reusing them will result in a weak, watery, and unpleasant cup.

My coffee tastes sour. What’s wrong?

Sourness usually indicates under-extraction. Try grinding your coffee finer, increasing the water temperature slightly (if below 195°F), or ensuring your bloom phase is adequate.

My coffee tastes bitter. What’s wrong?

Bitterness usually indicates over-extraction. Try grinding your coffee coarser, decreasing the water temperature slightly (if above 205°F), or reducing your brew time.

How long should the brewing process take?

For most pour-over methods, the total brew time, including the bloom, should be between 2 to 4 minutes, depending on the brewer and the amount of coffee.
