Can you make hot coffee with cold brew concentrate?
Yes. The easiest way is to dilute cold brew concentrate with hot water, roughly one part concentrate to two parts hot water, then adjust to taste. Brands and recipes differ, so check the label for the maker's suggested ratio. Avoid boiling or microwaving the concentrate, which can make it taste off.

Can you drink cold brew concentrate hot?
Yes. Cold brew concentrate is just strongly brewed coffee that was steeped in cold water. It is safe to dilute with hot water and drink warm. The result is often described as smoother and less bitter than coffee brewed hot.
How much hot water do you add?
Ratios vary by brand and by how strong the concentrate is, so read the label first. As a rough starting point, try about 1 part concentrate to 2 parts hot water, and use more water for a strong concentrate. Taste, then add more concentrate if it is weak or more water if it is too strong.
| Goal | Rough starting ratio (concentrate : hot water; varies by brand) |
|---|---|
| Stronger mug | 1 : 1 to 1 : 2 |
| Regular mug | 1 : 2 to 1 : 3 |
| Milder | 1 : 4 |
Step by step
- Warm your mug with hot water for about a minute, then pour it out.
- Add the concentrate.
- Pour in hot (not rolling-boil) water and stir.
- Add milk, cream or sweetener if you like.
Can you heat cold brew in a microwave or on the stove?
You can, but it is less reliable. The Bruer guide says microwaving overheats the coffee quickly and it then tastes off. If you heat it, use low heat or short bursts and stop before it boils. Mixing with hot water gives more control.
Making a hot-friendly concentrate
Bruer describes making the concentrate at 1:6 coffee to water by weight instead of the usual 1:12, then diluting it with an equal part of hot water, which it says brings the drink to about 135 degrees F. That is one maker’s method, not a rule.
Common mistakes
- Adding too much water and getting a weak cup. Add concentrate a little at a time.
- Using boiling water straight onto cold glass.
- Forgetting that concentrate is stronger than ready-to-drink cold brew. Check the label.
