How to Make Degree Coffee: Step-by-Step Guide

Quick answer

• Dial in your water temp. Aim for 195-205°F (90-96°C).
• Fresh, quality beans are non-negotiable. Grind just before brewing.
• Use the right coffee-to-water ratio. A good starting point is 1:15 to 1:17.
• Filter choice matters. Paper, metal, cloth – they all change the taste.
• Keep your gear clean. Old coffee oils are the enemy of good flavor.
• Experiment! Small tweaks make a big difference.

Who this is for

• You’re tired of “meh” coffee and ready to level up.
• You’ve got a decent brewer but feel like you’re not getting the most out of it.
• You want to understand the “why” behind a great cup, not just follow a recipe.

What to check first

Brewer type and filter type

Know what you’re working with. Is it a pour-over, French press, AeroPress, or something else? Each needs a slightly different approach. Your filter—paper, metal, or cloth—will also affect clarity and body. Paper filters catch more oils, leading to a cleaner cup. Metal filters let more through, giving you a richer mouthfeel.

Water quality and temperature

This is huge. Tap water can have funky flavors. Filtered water is usually best. For temperature, you want it hot, but not boiling. Boiling water can scorch the grounds. Too cool, and you won’t extract enough flavor. Aim for the sweet spot: 195-205°F (90-96°C). A thermometer is your friend here.

Grind size and coffee freshness

Freshness is king. Buy whole beans and grind them right before you brew. Pre-ground coffee loses its aroma and flavor fast. Grind size depends on your brewer. Coarser for French press, finer for espresso. For most drip and pour-over, a medium grind works well. Think coarse sand.

Coffee-to-water ratio

This is your recipe. A common starting point is a 1:15 ratio. That means 1 gram of coffee for every 15 grams (or ml) of water. So, for a 12 oz (355 ml) mug, you’d use about 24 grams of coffee. Adjust to your taste – more coffee for stronger, less for weaker.

Cleanliness/descale status

This is often overlooked. Old coffee oils build up and go rancid, making even fresh beans taste bitter or stale. Regularly clean your brewer, grinder, and any carafes. Descale your machine if it’s an automatic drip brewer. It’s a simple step that pays off big time.

Step-by-step (brew workflow)

1. Heat your water.

• What to do: Heat filtered water to 195-205°F (90-96°C). Use a kettle with temperature control or a thermometer.
• What “good” looks like: Water is hot but not actively boiling. Small bubbles might be forming, but it’s not a rolling boil.
• Common mistake: Using boiling water. This scorches the coffee. Avoid by letting the kettle sit for 30-60 seconds after it boils, or by using a temperature-controlled kettle.

2. Weigh your coffee.

• What to do: Use a digital scale to weigh your whole beans. A good starting ratio is 1:15 (coffee to water). For a 12 oz cup, that’s roughly 24 grams of coffee.
• What “good” looks like: You have an accurate measurement of your coffee beans.
• Common mistake: Guessing the amount. This leads to inconsistent brews. Always use a scale for precision.

3. Grind your coffee.

• What to do: Grind the weighed beans just before brewing. Match your grind size to your brewer type.
• What “good” looks like: The grounds are the correct consistency for your brewer – e.g., medium for pour-over, coarse for French press.
• Common mistake: Grinding too fine or too coarse. Too fine can clog filters and lead to over-extraction (bitter). Too coarse leads to under-extraction (weak, sour).

4. Prepare your filter and brewer.

• What to do: If using a paper filter, rinse it with hot water. This removes papery taste and preheats the brewer. Discard the rinse water.
• What “good” looks like: The filter is wet, and the brewer is warm.
• Common mistake: Not rinsing the paper filter. This can leave a papery taste in your coffee.

5. Add coffee grounds.

• What to do: Add your freshly ground coffee to the prepared brewer. Gently shake to level the bed of grounds.
• What “good” looks like: The coffee grounds form an even layer.
• Common mistake: Leaving the grounds uneven. This can cause uneven extraction, where some parts of the coffee bed brew faster than others.

6. Bloom the coffee (for pour-over/drip).

• What to do: Pour just enough hot water (about twice the weight of the coffee) to saturate all the grounds. Let it sit for 30-45 seconds.
• What “good” looks like: The coffee grounds puff up and release CO2, creating a bubbly “bloom.”
• Common mistake: Skipping the bloom. This helps release trapped gases, leading to a more even extraction and better flavor.

7. Begin the main pour.

• What to do: Slowly and steadily pour the remaining hot water over the grounds. Use a circular motion, starting from the center and moving outwards, avoiding pouring directly onto the filter paper.
• What “good” looks like: A consistent, controlled pour that keeps the coffee bed saturated without flooding it.
• Common mistake: Pouring too fast or all at once. This can create channels and lead to uneven extraction.

8. Complete the brew.

• What to do: Continue pouring until you reach your desired water weight. Let the water drain through completely.
• What “good” looks like: All the water has passed through the coffee bed, leaving a rich brew.
• Common mistake: Stopping the pour too early or letting it drip too long. Too early means under-extraction. Draining too long can lead to bitter flavors from over-extracted fines.

9. Serve immediately.

• What to do: Remove the brewer and pour your coffee into a preheated mug.
• What “good” looks like: A flavorful, aromatic cup of coffee.
• Common mistake: Letting brewed coffee sit on a hot plate. This bakes the coffee and ruins the flavor.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale beans	Flat, dull, or bitter coffee	Buy fresh, whole beans and grind just before brewing. Store beans in an airtight container away from light and heat.
Incorrect grind size	Under-extracted (sour) or over-extracted (bitter)	Adjust grind size based on your brewer. Coarse for French press, medium for pour-over, fine for espresso. Experiment.
Water temperature too high	Scorched, bitter, acrid coffee	Use water between 195-205°F (90-96°C). Let boiling water cool for 30-60 seconds or use a temperature-controlled kettle.
Water temperature too low	Weak, sour, underdeveloped coffee	Ensure water reaches the target temperature range. A thermometer is your best friend here.
Inconsistent coffee-to-water ratio	Coffee is too weak or too strong	Use a digital scale to weigh both your coffee and your water for precise measurements every time. Start with 1:15 and adjust.
Not rinsing paper filters	Papery, unpleasant taste in the coffee	Always rinse paper filters with hot water before adding grounds. Discard the rinse water.
Uneven coffee bed	Uneven extraction, inconsistent flavor	Gently shake the brewer to level the coffee grounds after adding them. Avoid compacting them.
Skipping the bloom	Trapped CO2 leads to less even extraction	For pour-over and drip, always perform the bloom step. It releases gases for better flavor.
Pouring water too fast or unevenly	Channels form, leading to poor extraction	Pour water slowly and steadily in controlled circles. Avoid pouring directly on the filter paper.
Letting coffee sit on a hot plate	Coffee becomes burnt and bitter	Serve coffee immediately after brewing. If you need to keep it warm, use a thermal carafe.
Dirty equipment	Rancid oils ruin flavor, off-tastes	Clean your brewer, grinder, and any storage containers regularly. Descale automatic machines as recommended.

Decision rules (simple if/then)

• If your coffee tastes sour, then try grinding finer because finer grinds increase extraction, which can balance out sourness.
• If your coffee tastes bitter, then try grinding coarser because coarser grinds reduce extraction, which can combat bitterness.
• If your coffee tastes weak, then try increasing the coffee dose or decreasing the water ratio (e.g., from 1:17 to 1:15) because you’re not using enough coffee for the amount of water.
• If your coffee tastes too strong, then try decreasing the coffee dose or increasing the water ratio (e.g., from 1:15 to 1:17) because you’re using too much coffee for the amount of water.
• If your coffee has a papery taste, then ensure you are thoroughly rinsing your paper filters with hot water before brewing.
• If your automatic drip machine brews slowly, then it likely needs descaling because mineral buildup can impede water flow.
• If your French press coffee has a lot of sediment, then try a coarser grind or a finer mesh filter because this reduces the amount of fine particles that pass through.
• If your pour-over coffee flows too quickly, then try a finer grind because a finer grind will slow down the water flow.
• If your pour-over coffee flows too slowly, then try a coarser grind because a coarser grind will speed up the water flow.
• If your coffee tastes muddy, then consider using a different filter type (like a paper filter instead of a metal one) because paper filters trap more fine particles.
• If your coffee lacks aroma, then ensure you are using freshly roasted beans and grinding them right before brewing because aroma is the first thing to go.
• If you’re unsure about water temperature, then aim for just off the boil (195-205°F / 90-96°C) because this range is optimal for most brewing methods.

FAQ

What’s the ideal water temperature for brewing coffee?

Most experts agree that the sweet spot for water temperature is between 195°F and 205°F (90°C to 96°C). Water that’s too hot can scorch the coffee grounds, leading to a bitter taste. Water that’s too cool won’t extract enough flavor, resulting in a weak, sour cup.

How important is the freshness of coffee beans?

Extremely important. Coffee is a perishable product. Once roasted, its volatile aromatic compounds start to degrade. Grinding beans just before brewing preserves the maximum amount of flavor and aroma.

What’s the best way to store coffee beans?

Store whole beans in an airtight container, away from light, heat, and moisture. Avoid the refrigerator or freezer, as condensation can negatively impact the beans. Buy smaller quantities more frequently to ensure freshness.

How do I know if my grind size is right?

The right grind size depends on your brewing method. For French press, it should be coarse, like sea salt. For pour-over and drip, medium, like coarse sand. For espresso, it’s very fine. If your coffee is too bitter, try coarser; if too sour, try finer.

What is the “bloom” phase in pour-over coffee?

The bloom is the initial 30-45 seconds after you pour a small amount of hot water onto fresh coffee grounds. The grounds release carbon dioxide, puffing up and bubbling. This step helps ensure even extraction by allowing gases to escape.

How often should I clean my coffee maker?

You should rinse your brewer and carafe after every use. For automatic drip machines, a deep clean or descaling is recommended every 1-3 months, depending on your water hardness and usage. Old coffee oils are a major flavor killer.

What is a good starting coffee-to-water ratio?

A widely accepted starting point is a 1:15 ratio, meaning 1 gram of coffee to 15 grams (or ml) of water. For example, 24 grams of coffee for a 12 oz (355 ml) cup. You can adjust this to your preference – more coffee for stronger, less for weaker.

Does the type of filter really make a difference?

Yes, absolutely. Paper filters produce a cleaner cup by trapping more oils and fine sediment. Metal filters allow more oils and some fines through, resulting in a richer, fuller-bodied coffee. Cloth filters offer a middle ground.
