Cold brew is one of the easiest ways to make coffee at home.
You do not need a machine. You do not need perfect pouring technique. You do not even need hot water.
You need coffee, water, a container, a filter, and time.
What cold brew is
Cold brew is coffee brewed with cool or room-temperature water over many hours.
Because the extraction is slow, the cup usually tastes smoother, less sharp, and less bitter than hot coffee. It can work well with ice, milk, tonic, or just water.
In Indian summers, that makes sense.
What you need
Start simple:
- 60g coarsely ground coffee
- 500g clean drinking water
- Jar or bottle
- Spoon
- Filter paper, cloth, or fine sieve
This makes a concentrate. You can dilute it later.
Basic recipe
- Add coffee to a clean jar.
- Add water.
- Stir gently so all grounds are wet.
- Cover the jar.
- Leave it at room temperature for 12 to 16 hours.
- Filter slowly.
- Store in the fridge.
Serve over ice and dilute to taste.
What coffee should you use?
Medium roasts are a good starting point.
Chocolatey, nutty, caramel-like coffees work well. Fruity coffees can also be interesting, but cold brew may soften some acidity.
You do not need to use your most expensive coffee first. Cold brew is forgiving, but it can also hide delicate notes.
How to drink it
Try:
- One part cold brew concentrate, one part water
- Cold brew over ice with a splash of milk
- Cold brew with tonic
- Cold brew with a little jaggery syrup if you like sweetness
There is no moral issue with adding milk or sweetness. Make something you want to drink.
Common mistakes
Grinding too fine can make filtering painful and the cup muddy.
Steeping too long can make the coffee heavy and dull.
Using too little coffee can make it taste watery.
Not filtering properly can leave sediment.
How to adjust
If it is too strong, dilute more.
If it is too weak, use more coffee next time.
If it tastes harsh, reduce steep time or grind coarser.
If it tastes boring, try a fresher coffee or a slightly different roast.
Final note
Cold brew is not complicated. It is a patient recipe, not a technical one.
Make one batch, note your ratio and steep time, and adjust the next one. Brew Tracker is useful here because cold brew changes are slow; you will not remember the exact ratio three days later.
