Pour-Over Brew Guide

A standard kettle gives you no control over flow rate. A gooseneck lets you pour slowly and precisely, which directly affects how evenly the bed extracts. It’s the single biggest upgrade after a good grinder, and it costs less than a bag of good beans.

Coffee is 98% water. Hard tap water mutes flavor. Distilled water tastes hollow and flat. Filtered water, even a basic Brita, gets you most of the way there. You’re aiming for lightly mineralized, not stripped.

Beans roasted within the last 2–4 weeks are the sweet spot. Under 5 days off roast and the CO₂ off-gassing fights your extraction. Too far past 4 weeks and the complexity starts to fade. The bloom tells you everything: a vigorous, domed rise means your beans are alive.

Pour your bloom water in a slow spiral and watch what happens. Fresh beans will puff up and bubble actively, sometimes dramatically. Stale beans barely move. That rise is CO₂ releasing, and letting it escape before your main pour is what prevents uneven extraction. A flat bloom is a sign to find fresher beans.

Saturating the grounds for 45 seconds before the main pour lets CO₂ escape. Skip it and the gas creates channels in the bed during your main pour. You end up with sour spots and bitter spots in the same cup.

With a hand grinder, uniformity matters more than hitting an exact coarseness. A consistent medium grind will outperform an inconsistent fine grind every time. If your cup is bitter, go coarser. Sour or thin, go finer. One adjustment per brew, not both at once.

A cold vessel, cold filter, and cold mug all pull heat out of your brew. Rinsing your filter pre-warms the dripper and removes papery off-notes at the same time. Takes 20 seconds. Makes a real difference in final temperature and extraction clarity.

A faster pour agitates the grounds more and extracts faster. A slow, controlled pour is gentler and more even. Most pour-over recipes land in a 3–4 minute total brew window. If you’re consistently over or under, adjust your grind before you adjust your pour speed.

1:15 is a solid baseline, but your specific beans, grinder, water, and palate all shape the final cup. Adjust in 0.5 increments and note what changed. Most people settle somewhere between 1:14 and 1:16. The best ratio is the one that made the cup you want to drink again.
