How to brew: Cold brew

Brewed cold, coffee turns smooth, sweet and very low in acidity. Make a concentrate and dilute it when you serve.

Quick answer

Use 100 g of coarsely ground coffee for 800 ml of cold water (1:8 ratio) and leave it 12 to 18 hours in the fridge. Dilute the concentrate 1:1 to serve.

  3. Strain through a paper or cloth filter.
  4. Serve over ice, 1 part concentrate to 1 part water or milk. It keeps for up to a week in the fridge.

Questions

Does cold brew have more caffeine?

The concentrate is strong, but once diluted 1:1 a cup is close to a regular filter coffee.
