Cold brew concentrate

Applies to: batch cold brew immersion concentrate.

1. Combine coffee and water at roughly a 1:8 ratio.
2. Stir gently to fully saturate the grounds, seal, and label with the start time and discard time (start + 7 days).
3. Steep at room temperature or refrigerated for 16–18 hours.
4. Filter thoroughly — a paper filter, fine mesh, or dedicated cold-brew filter — to remove fine sediment.
5. Refrigerate the finished concentrate immediately at 4°C or below.
