Cold Brew Guide

Cold brew coffee has become one of the most popular ways to enjoy coffee at home thanks to its smooth, low-acidity flavor and refreshing taste. Unlike traditional brewing methods that use hot water, cold brew is made by steeping coffee grounds in cold or room-temperature water for an extended period—usually between 12 and 24 hours. This slow extraction process produces a coffee concentrate that is naturally sweet, mellow, and less bitter than hot-brewed coffee.

Because cold brew relies on time rather than heat to extract flavor, grind size, coffee ratios, and steep time all play an important role in the final result. Most cold brew recipes use a coarse grind and a higher coffee-to-water ratio to create a concentrate that can be diluted with water, milk, or ice. When brewed correctly, cold brew delivers a rich, chocolatey profile with a smooth body that works well for both iced coffee drinks and milk-based beverages.

Cold brew can be prepared using specialized cold brew makers, mason jars, French presses, or simple immersion brewing systems. Dedicated cold brew devices often include built-in filters and containers that make brewing and storage easier, but the process itself is simple enough for anyone to do at home with basic equipment.

In this section of CoffeeGearHub, you’ll find step-by-step cold brew recipes, grind size recommendations, brew ratio guides, and gear recommendations to help you make better cold brew coffee.
