Cold Brew: How Long It Lasts, How to Tell if It’s Still Good, and Mistakes Serious Cafés Avoid
Being cold-extracted, Cold Brew is sometimes mistakenly considered "non-perishable." In reality, it is a fresh water-based food, free of preservatives and highly perishable: storing it for weeks compromises its aroma and safety.
The chemical and microbiological shelf life follows precise rules:
|
Product condition |
Maximum shelf life in fridge (2-4°C) |
Risk of degradation |
|
Pure concentrate, airtight container |
Max 7 days |
After 7 days, it loses freshness, oxidizes, and becomes flat or vinegary. |
|
Ready-to-drink diluted (with water) |
3-4 days |
Higher water activity accelerates microbial growth. |
|
Mixed with animal or plant-based milk |
24 hours |
Rapid microbiological deterioration; gastrointestinal risk. |
At Garage Coffee Bros., we follow HACCP self-control protocols and label each batch with the exact filtration end time, discarding any product older than one week. When ordering at the counter, always ask for the actual extraction date: if the answer is vague, it's better to avoid it.
