Cold Brew Ratio
A precise tool.
What is the Cold Brew Ratio & How does it work?
Cold brew is a smooth, low‑acid coffee made by steeping coarsely ground beans in cold water for an extended period. The extraction process depends heavily on the water‑to‑coffee ratio, which determines strength, flavor balance, and caffeine concentration. Professional baristas often use a ratio ranging from 1 : 6 to 1 : 10 (coffee : water) to tailor the brew to different bean profiles. Adjusting the ratio allows you to control dilution, mouthfeel, and the presence of nuanced aromatic compounds. Mathematically, the ratio is expressed as the volume of water (W) divided by the weight of coffee (C). By calculating this ratio, you can standardize recipes, scale batches, and ensure consistent quality across servings.
\frac{W}{C}
W = water volume (ml) C = coffee weight (g)

Frequently Asked Questions
What is the ideal water-to-coffee ratio for cold brewing?
The ideal ratio typically ranges from 1:6 to 1:10, depending on how strong you like your cold brew.
How long should I steep my coffee for cold brewing?
Steep for at least 12 hours, but up to 48 hours for a more robust flavor.
Can I use any type of coffee beans for cold brewing?
Yes, you can use any type, but darker roasts generally work well as they hold up better in the long steeping process.
How do I adjust the ratio to make my cold brew stronger or weaker?
To make it stronger, decrease the water amount; for a weaker brew, increase the water amount while keeping the coffee amount constant.
What is the best temperature for steeping cold brew?
Use room temperature water. Cold brewing with hot water can result in over-extraction and a bitter taste.
How do I store my homemade cold brew once it's made?
Store it in an airtight container in the refrigerator for up to 10 days.
Can I add sugar or other sweeteners to my cold brew after brewing?
Yes, you can add sugar or any other sweetener of your choice after brewing to taste.
