Cold Brew

Cold Brew – brewing guide
14.06.2019 Maria Ariyo

What’s cold brew and how do you make it?

Cold brewing is a coffee brewing process where the coffee is extracted into cold water over a long period of time (often over 12 hours). The water in the process is often either room temperature or cold. After the extraction, the coffee is strained with either a french press or with the help of a strainer and filter paper or cloth. Often cold brew is mixed into milk or water and served with ice, as a frappe or with other flavourings.

Normal coffee and cold brew have some differences in the flavour and the chemical composition because while making cold brew, the coffee beans do not come into contact with boiling water. Cold brew contains less caffeine and acids than traditional coffee and is also often less bitter than its counterparts. It is also often extracted a bit stronger since it can be mixed with milk or water.

Cold brew allows the different flavours and nuances in the coffee to shine, so especially interesting choices for cold brew are light roasts, that have various fresh flavours. Another thing to try is to prepare natural processed coffee with cold brew. The sweetness of the coffee berry is present in natural processed coffees, so it makes your drink sweeter as well.

Here’s how to brew 1 liter of coffee with Slurp’s Cold brew recipe:

Brewing time: 12 hours
Final quantity of coffee: 1 liter
Grinding: Coarser than for regular filter coffee. Using the Wilfa grinder, we recommend the French Press or Steap setting.
The ratio of coffee to water: 150g coffee, 1l water
You will also need: Two 2 liter containers/bottles, a metal sieve, and filter paper or gauze

  1. Put the coffee and the water into a container.
  2. Let it sit in room temperature preferably for at least 12 hours.
  3. Strain the coffee into the other container using a sieve and filter paper or gauze.
  4. Your Cold brew is ready!


  • Cold brew coffee will stay good for approximately a week in the fridge when stored in an airtight container.
  • You can also pour the brewed coffee into a French Press and press the plunger immediately down to filter the bigger pieces of coffee out. Afterwards you can pour the coffee through a filter paper with the pour over method to remove even the last coffee grinds.
  • You can add milk and flavor syrups according to your own taste.
  • On a warm day, adding ice will keep your drink cold for longer.

  1. […] Cold brew is a brewing method, in which the coffee flavors are allowed to extract over time, making the coffee taste less bitter. While brewing cold brew, the coffee to water ratio is usually a bit bigger than in normal coffee. Approximately 1 unit of coffee for every 8 units of water. The extremely coarsely ground coffee is mixed into cold water and allowed to sit for 12-24 hours. Afterwards it is drained and sifted to get rid of the coffee grounds. Read more about cold brew here.
