Calculadora de Cold Brew

The Cold Brew Calculator helps you make the perfect cold brew at home using the classic 1:4 ratio (coffee to water). Unlike traditional coffee, cold brew is a cold infusion that extracts smooth, less acidic flavors. With this tool, you calculate the exact amount of ground coffee needed based on your water volume, ensuring a balanced concentrate that will be diluted later when serving.

The operation is simple: you enter the amount of water you plan to use (in milliliters), and the calculator divides it by 4 to get the coffee weight in grams. This 1:4 ratio is the most common for cold brew concentrate, which is later diluted with equal parts water or milk (1:1). The recommended infusion time is 12 to 24 hours in the refrigerator, resulting in a full-bodied, low-acidity beverage with natural sweetness.

Use this calculator when you want to prepare cold brew for the week, whether for straight consumption (after dilution) or as a base for drinks and recipes. It's ideal for those who prefer iced coffee without the bitterness of traditional methods. Remember to use a coarse grind, similar to French press, to avoid over-extraction. After infusion, strain through a paper or cloth filter for a clean, sediment-free liquid.

Important tips: do not use very fine coffee, as it can make the brew cloudy. The 1:4 ratio is for concentrate; if you want to drink it straight (undiluted), use 1:8 or 1:10. The concentrate lasts up to 2 weeks in the fridge, but flavor is best within the first 5 days. Always store in an airtight container and avoid air exposure to preserve aroma.
