How to Make Cold Brew at Home: Timing, Measurements, and Variations

Cold Brew is not the "iced coffee" from cafes (hot brewed and then cooled, often bitter and oxidized). It is a prolonged cold immersion extraction that does not thermally stress the bean, resulting in a naturally sweet and smooth flavor.

Basic recipe: ratio 1:10 (e.g., 100 grams of coffee per 1 liter of purified cold water). Grind the beans coarsely to avoid over-extraction. Combine water and coffee in an airtight pitcher, stir, and leave in the refrigerator at 4°C for 14-16 hours. Carefully filter through a paper filter. The concentrate is excellent over ice or mixed with tonic water for a summer Coffee Tonic.
