Making Coffee for Two Cups

Quick answer

• Use a 1:15 to 1:17 coffee-to-water ratio. That’s roughly 30-35 grams of coffee for 16-17 oz of water.
• Aim for a medium grind, like coarse sand.
• Start with water just off the boil, around 200-205°F.
• Pre-heat your brewer and mugs. It makes a difference.
• Bloom the coffee for 30 seconds. Let it degas.
• Pour slowly and evenly. Don’t rush the process.
• Taste it. Adjust grind or ratio for next time.
• Keep it clean. A clean brewer makes better coffee.

Who this is for

• Couples or roommates who want to share a fresh pot.
• Anyone tired of making one cup at a time.
• People who want to dial in their coffee for a specific yield.

What to check first

Brewer type and filter type

You’re probably using a pour-over, French press, or maybe an auto-drip machine. Each needs a specific filter. Paper filters are common for pour-overs and drip machines. Metal filters work for French presses and some pour-overs. Make sure your filter is the right size and type for your brewer. A badly fitting filter can lead to weak coffee or grounds in your cup.

Water quality and temperature

Tap water can have flavors that mess with your coffee. Filtered water is usually best. For temperature, think just off the boil. Around 200-205°F is a sweet spot. Too hot, and you’ll scorch the grounds. Too cool, and you won’t extract enough flavor.

Grind size and coffee freshness

Freshly roasted beans are key. Look for a roast date on the bag. Grind your beans right before you brew. For two cups, a medium grind is a good starting point, like coarse sand. Too fine, and it’ll be bitter. Too coarse, and it’ll be weak.

Coffee-to-water ratio

This is how much coffee you use compared to water. For two cups (about 16-17 oz total liquid), try starting with a 1:16 ratio. That’s roughly 30-35 grams of coffee for 500-550 ml (16-17 oz) of water. You can adjust this later based on taste.

A precise coffee scale can help you nail this ratio every time, ensuring your coffee is perfectly balanced.

Cleanliness/descale status

Old coffee oils build up and make your coffee taste stale or bitter. Regularly clean your brewer, carafe, and mugs. If you have an auto-drip machine, descale it every few months, especially if you have hard water. Check your brewer’s manual for specific cleaning instructions.

Step-by-step (brew workflow)

1. Heat your water.

• What to do: Bring filtered water to a boil, then let it sit for about 30 seconds to cool slightly.
• What “good” looks like: Water temperature is around 200-205°F.
• Common mistake: Using boiling water directly. This can scorch the coffee grounds. Let it cool a bit.

2. Grind your coffee.

• What to do: Weigh out your whole beans (around 30-35 grams for 16-17 oz) and grind them to a medium consistency.
• What “good” looks like: The grounds resemble coarse sand.
• Common mistake: Grinding too fine or too coarse. This affects extraction. Grind right before brewing for freshness.

3. Prepare your brewer.

• What to do: Place your filter in the brewer. If it’s a paper filter, rinse it with hot water.
• What “good” looks like: The filter is seated correctly and any paper taste is rinsed away.
• Common mistake: Not rinsing paper filters. This can leave a papery taste in your coffee.

4. Add coffee grounds.

• What to do: Put the freshly ground coffee into your prepared brewer. Gently shake it to level the bed of grounds.
• What “good” looks like: An even layer of coffee grounds.
• Common mistake: Leaving a mound or uneven surface. This can lead to uneven extraction.

5. Pre-heat your mugs.

• What to do: Pour some hot water into the mugs you’ll be using and let them sit for a minute. Discard the water.
• What “good” looks like: Warm mugs ready to receive hot coffee.
• Common mistake: Pouring hot coffee into cold mugs. The coffee cools down too fast.

6. Bloom the coffee.

• What to do: Pour just enough hot water (about double the weight of your coffee) to saturate all the grounds. Wait 30 seconds.
• What “good” looks like: The grounds puff up and release CO2, forming a “bloom.”
• Common mistake: Skipping the bloom or pouring too much water. This step is crucial for even extraction.

7. Start pouring.

• What to do: Begin pouring the rest of your hot water in slow, controlled circles, starting from the center and moving outwards. Aim for a steady stream.
• What “good” looks like: A consistent pour that keeps the grounds saturated without flooding the brewer.
• Common mistake: Pouring too fast or in large bursts. This can create channels and uneven extraction.

8. Continue pouring until done.

• What to do: Keep pouring until you’ve added your total target water amount (16-17 oz). Try to finish pouring within 2-3 minutes for most pour-overs.
• What “good” looks like: The brewer is empty, and you have your desired amount of coffee.
• Common mistake: Over-extracting by pouring too slowly or for too long. This can lead to bitterness.

9. Let it drip.

• What to do: Allow all the water to pass through the grounds.
• What “good” looks like: A clean drip, with no water pooling excessively.
• Common mistake: Stopping the brew too early or letting it drip for too long. Timing is important.

10. Serve and enjoy.

• What to do: Remove the brewer. Swirl the coffee gently if it’s in a carafe, then pour into your pre-heated mugs.
• What “good” looks like: Two cups of delicious, hot coffee.
• Common mistake: Not swirling. This can leave the coffee unevenly mixed.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes bitter, then try a coarser grind because finer grinds extract more easily, leading to bitterness.
• If your coffee tastes weak or sour, then try a finer grind because coarser grinds don’t extract enough flavor.
• If your coffee tastes flat, then check your bean freshness because old beans lose their aroma and flavor.
• If your coffee is too strong, then use less coffee or more water because you’re using too high a coffee-to-water ratio.
• If your coffee is too weak, then use more coffee or less water because you’re using too low a coffee-to-water ratio.
• If your water is boiling, then let it cool for 30-60 seconds because water that’s too hot will scorch the grounds.
• If you notice paper taste, then rinse your paper filter thoroughly because residual paper can affect flavor.
• If your brew time is too short (e.g., under 2 minutes for pour-over), then your grind might be too coarse or you’re pouring too fast.
• If your brew time is too long (e.g., over 4 minutes for pour-over), then your grind might be too fine or you’re pouring too slowly.
• If your coffee has an off-flavor, then clean your equipment because old oils can build up and turn rancid.
• If your coffee has a metallic taste, then check your water quality because some tap water can impart mineral flavors.

FAQ

How much coffee do I need for two cups?

For about 16-17 oz of coffee, aim for 30-35 grams of whole beans. This is a good starting point for a 1:15 to 1:17 ratio.

What’s the best grind size for two cups?

A medium grind, similar to coarse sand, is usually a good bet. Adjust it based on your brewer type and how the coffee tastes.

Should I use hot water or boiling water?

Use water that’s just off the boil, around 200-205°F. Boiling water can burn the coffee grounds, leading to a bitter taste.

How do I avoid bitter coffee?

Bitter coffee often means over-extraction. Try a coarser grind, slightly cooler water, or a shorter brew time. Make sure your equipment is clean too.

My coffee tastes weak. What should I do?

Weak coffee usually means under-extraction. Try a finer grind, hotter water (closer to 205°F), or ensure you’re using enough coffee for the amount of water.

Is it okay to use pre-ground coffee?

It’s best to grind your beans right before brewing. Pre-ground coffee loses its flavor and aroma much faster, impacting the final cup.

What if my pour-over drips too fast?

If it’s dripping too fast, your grind is likely too coarse. Try grinding a bit finer next time.

How important is pre-heating my mugs?

It’s a small step that makes a big difference. Pre-heated mugs keep your coffee hotter for longer, allowing you to enjoy the full flavor profile.
