Cold Brew Concentrate vs Ready-to-Drink

The word concentrate only makes sense relative to intended dilution. Record both the initial grounds-to-water ratio and how much water or milk you add at serving.

Good starting point

As a trial, make 80 g coffee with 480 g water (1:6); after filtration, begin by mixing one part concentrate with one part water or milk, then adjust.

What to know before you begin

Keeping concentrate and dilution calculations separate prevents confusing product labels and allows consistent iced drinks.

Step-by-step method

1. Confirm the brewing vessel is large enough for swollen grounds and the full water amount.
2. Steep chilled using clean utensils and filter thoroughly.
3. Weigh the liquid concentrate you actually recovered rather than assuming it equals input water.
4. For each serving, add a measured amount of water or milk to a measured amount of concentrate.
5. Record the dilution that tastes balanced and label the container clearly.

Problems to recognize

• Ratios of beans to brew water are not equivalent to finished drink strength: grounds retain water.
• A 1:6 concentrate is not espresso and may still taste different from hot coffee.
• Do not assume a fixed caffeine count; it depends on the recipe and portion.

Run a useful comparison

Test 50 g concentrate with 50 g water versus 50 g concentrate with 100 g water to isolate dilution preference.
