7 Common Pour-Over Coffee Mistakes to Avoid When Making Coffee At Home

Making a great pour over at home requires amazing coffee but doesn't require complex or expensive equipment.

Pour over is simple. Not easy. There's a difference.

Most bad pour overs come down to the same handful of fixable mistakes. We brew pour over every day at our City Heights café in San Diego. Here's what actually matters.

By avoiding these 7 common mistakes you can make even tastier coffee at home.

☕ Using Stale or Pre-Ground Coffee 

Coffee goes stale fast. Ground coffee goes stale faster. Once you grind, you've got maybe 20-30 minutes before flavor starts dropping off. Buy whole bean. Grind right before you brew. That's it.

• Roast date matters more than origin or price
• Look for a roast date on the bag, not a "best by" date
• Aim to use coffee within 2-4 weeks of roast

🏺 Incorrect Grind Size

Grind size controls how fast water moves through the coffee. That controls extraction. Extraction controls flavor.

• Too fine: water slows down, over-extracts, tastes bitter
• Too coarse: water rushes through, under-extracts, tastes thin and sour
• Target: medium-fine, like coarse sea salt
• If your brew is bitter, go coarser. If it tastes weak, go finer.

Adjust one variable at a time.

💧 Wrong Coffee-to-Water Ratio

Eyeballing this is how you end up with watery coffee or something you could strip paint with.

• Start at 1:16. That's 1 gram of coffee per 16 grams of water.
• A standard cup: 25g coffee to 400g water
• Use a kitchen scale. Cheap ones work fine.

Once you find a ratio you like, write it down.

🔥 Water Temperature Too Hot or Too Cold

Boiling water burns coffee. Cold water under-extracts it. There's a window.

• Target: 195-205°F (90-96°C)
• No thermometer? Boil water and let it sit off heat for 30-45 seconds
• Lighter roasts can handle the higher end. Darker roasts, back off slightly.

🚰 Pouring Too Fast or Too Slow

Your pour controls saturation. Uneven saturation means uneven extraction.

• Pour in slow, steady circles from the center outward
• Keep the bed evenly wet throughout the brew
• Total brew time for a standard cup should be 3-4 minutes
• Faster than 2.5 minutes: grind finer or slow your pour
• Slower than 4.5 minutes: grind coarser

⏳ Skipping the Bloom

Fresh coffee is full of CO2. CO2 repels water. Skip the bloom and you're pouring water over a gas barrier.

• Pour 2x the coffee weight in water first (50g water for 25g coffee)
• Wait 30-45 seconds. You'll see it bubble and expand. That's the gas escaping.
• Then continue your brew normally

Older coffee won't bloom much. That's actually useful information about your beans.

🧼 Not Cleaning Your Equipment

Coffee oils go rancid. Rancid oils make your coffee taste like last Tuesday.

• Rinse your dripper and kettle after every brew
• Deep clean weekly with hot water and a small amount of unscented dish soap
• If your clean equipment smells like old coffee, it needs a longer soak

Master these techniques for a perfectly balanced, flavorful pour-over every time! ☕🔥

Frequently Asked Questions

What grind size should I use for pour over coffee? Medium-fine, similar to coarse sea salt. If your coffee tastes bitter, go a bit coarser. If it tastes weak or sour, go finer.

What water temperature is best for pour over? 195-205°F (90-96°C). No thermometer? Boil and wait 30 seconds.

How much coffee do I use for pour over? Start with a 1:16 ratio. For one cup, that's 25g of coffee to 400g of water.

How long should a pour over take to brew? 3-4 minutes total. Outside that window, adjust your grind size.

What does the bloom do in pour over? It releases CO2 from fresh coffee so water can actually extract evenly. Pour twice the coffee weight in water, wait 30-45 seconds, then continue.

Does the pour over dripper matter? Less than most people think. Grind size, ratio, and water temperature matter more. A $15 plastic Hario V60 makes excellent coffee.

What coffee works best for pour over? Freshly roasted whole bean, ground right before brewing. Light to medium roasts tend to shine in pour over. Explore our single origins if you want something worth brewing carefully.
