Temperatures rise and the body screams for caffeine - time for an ice-cold coffee. There are plenty of ways to get a refreshing kick and you can prepare almost all of them yourself at home.
Basically you can distinguish between cold brewed and iced drinks. Cold Brew coffee is made with water at maximum room temperature. Iced coffee is prepared conventionally and then chilled quickly. It is important that you cool down iced drinks quickly so that you can avoid a bitter taste.
1. Cold brewed coffee
Cold Brew differs significantly from the usual coffee in terms of extraction. The water is not heated and so the extraction takes much longer - at least 10 hours compared to about 4 minutes with a hot brewed coffee. But why do we go to all this trouble? Cold Brew tastes very mild, round and has hardly any bitter taste. Coffee extracts about 90% of the flavour elements but only about 15% of the oils and acids in coffee.
Make Cold Brew yourself
It's very easy to make - you just need to prepare it early as it takes a long time to brew. Below you will find our favourite recipe and bean recommendations. With Cold Brew, you can experiment with the amount of coffee and water, the grind and the brewing time:
- approx. 100 grams of coffee in 1 liter of water
- Coarse grinding degree
- Fill into a bottle together and close
- Leave the coffee at room temperature and wait at least 12 hours. Shake carefully from time to time.
- After 12 hours the taste and also the acidity is very pronounced.
- After 24 hours, the coffee is significantly stronger and the characteristic flavours and acidity are superimposed. But the coffee now has a pronounced body.
- Filter (e.g. through a normal filter for filter coffee) and fill into a closable glass
The coffee is now highly concentrated so you can keep it in the fridge for a long time. You drink the cold brew either pure, on ice, with water, with milk (top picture) or with homemade almond milk.
