About Coffee Ratio Lab

Coffee Ratio Lab is an independent coffee website for people who brew at home and want better results without the jargon. We treat coffee like a friendly kitchen lab: measure, brew, taste, adjust. Our focus is the ratios, grind sizes, temperatures and small habits that turn an average cup into a great one.

What you'll find here

• Brew guides with exact ratios and step-by-step instructions for moka pots, French presses, AeroPress, pour over and cold brew.
• Buying guides that explain what features matter, so you can choose gear that suits your kitchen.
• Free calculators for coffee ratios, caffeine and cold brew dilution.
• Troubleshooting charts for bitter, sour, weak or muddy coffee.

Our approach

We write step-by-step guides for everyday home brewers: moka pots, French presses, AeroPress, pour over and cold brew. Every guide is checked against manufacturer instructions and widely accepted brewing guidance, and updated when we learn something better.

Every illustration on the site is drawn in-house for Coffee Ratio Lab. We don't sell products and we don't accept payment to feature brands. The site is supported by display advertising.
