Frequently Asked Questions
What is the ratio for cold brew concentrate vs ready-to-drink?
Ready-to-drink cold brew uses a 1:8 ratio (e.g., 125g coffee to 1,000ml water) poured straight over ice. A cold brew concentrate uses 1:4 (250g coffee to 1,000ml water), diluted 1:1 with milk or water when serving.
How long should cold brew steep?
Steep coarse grounds at room temperature for 14 to 16 hours, or in the refrigerator for 20 to 24 hours. Steeping beyond 24 hours extracts harsh woody tannins and bitterness.
