How to make it
- Grind the coffee coarse, so that it looks like breadcrumbs.
- Add cold water and stir until all the grounds are wet.
- Cover it and leave it in the fridge for 12 to 18 hours.
- Strain it through a paper filter or a fine sieve.
- Mix the concentrate about half and half with water or milk.
Which coffee to use
Medium and dark roasts with chocolate and nut flavors are the classic choice. Cold water brings out the deep, sweet side of a coffee and leaves most of its brightness behind.
