Concentré de Cold Brew

The name "cold brew" is used to define the act of submerging coarsely ground coffee in cold water over an extended period of time. This method is very popular for its convenience and also because it reduces the acidity and bitterness of a coffee, producing an approachable, and balanced result.

We suggest that you prepare it as a concentrate that can be stored in the fridge for several days. It can then be diluted with water or milk, or even added to a cocktail!

Pro tip

Some coffees will benefit from a shorter or longer extraction time. If your result is a little bitter, shorten the brew time by 1 hour. On the other hand, if your concentrate has a light and acidic taste, continue the extraction for an additional 1 or 2 hours.

You can keep your cold brew concentrate in the fridge for up to 2 weeks.

Preparation

Fill the kettle with fresh filtered water and bring to a boil.

Grind 100g of coffee and place it in the jar.

Pour 200g of water over the coffee, making sure to saturate all the coffee grounds evenly. Wait 30 seconds.

Add 400g of filtered water (room temperature). Stir, close the jar, and place in the fridge for 14 hours. You can set an alarm so that you don’t forget it!

Place a paper filter inside the sieve and rinse it with water. Place the sieve over an empty jar and pour the coffee into it. The filtering process may take up to 15 minutes.

Add water or milk to taste to dilute the concentrate. We recommend 1 part concentrate to 1 part water or milk.
