Ingredients (as the source specifies)
The source states no tokenised ingredient list for this drink, so no energy or caffeine figure is derived from it.
Further specification
Adopted ratio: 1:8 coarsely ground coffee to cold water · steep 14-18 hours at 2-5 °C · filter twice.
Service: 150 ml concentrate + 50 ml water or ice, per the in-house calibration.
Shelf life: 7 days chilled in a sealed, labelled bottle. After that, discard and log it.
Operating procedure
Applies to: batch cold brew immersion concentrate.
Target: 16–18 hours steep.
- Grind coarse — finer grinds make the concentrate difficult to filter clearly.
- Use room-temperature or cold filtered water, never hot.
- Have a clean, sanitised, sealable container ready and labelled before starting.
- Combine coffee and water at roughly a 1:8 ratio.
- Stir gently to fully saturate the grounds, seal, and label with the start time and discard time (start + 7 days).
- Steep at room temperature or refrigerated for 16–18 hours.
- Filter thoroughly — a paper filter, fine mesh, or dedicated cold-brew filter — to remove fine sediment.
- Refrigerate the finished concentrate immediately at 4°C or below.
- Low acidity, naturally sweet, smooth — this is expected from the cold, slow extraction, not a fault.
- Discard the batch at 7 days from brew date without exception, and record the discard.
Concentrate is typically diluted with water or milk to taste before serving, not served neat — check the specific recipe's dilution ratio.
