A Solid Recipe for Cold Brew Coffee

This recipe takes 24 hours and can last up to 4 weeks in the fridge. Drink with lots of ice.
Prep Time: 1 day
Straining: 5 minutes
Total Time: 1 day 5 minutes
Servings: 2 Liters
Cost: 6.50€

Equipment

  • Fine Mesh Strainer
  • 1 giant glass jar or jug 4-5L
  • glass jars or bottles with lids to store the cold brew in
  • big whisk for mixing

Ingredients

  • 500 g ground coffee (for filter coffee) ask your local café to grind for you unless you have a really really good grinder
  • 3 L cold water preferably filtered

Instructions

  • Add cold water and ground coffee to the big jar and mix really well with the whisk. Leave the lid open for 10 minutes to let some CO2 out. (Natural CO2 gas is released from coffee when mixed with water and especially when the coffee is very fresh)
    Mixing the cold brew coffee with a whisk.
  • Close lid and let sit at room temp for 20-24 hours.
  • Strain through a fine mesh strainer and store in glass bottles in the fridge.
    Using a fine mesh strainer to strain the coffee.
  • Set it in the fridge for up to 4 weeks. Serve over lots of ice and dilute with splash of milk, oat milk, almond milk, coconut milk or water because it's very strong.

Notes

There will be some sediment from the coffee grinds that go through the strainer. You can filter this through a coffee filter again after but this will take a long time. I let it chill in the fridge overnight and the next day most of the sediment is at the bottom and that's okay for me.
Because cold brew coffee doesn't use hot water you must take care to thoroughly clean the brewing jar, the whisk and the storing jars with hot soapy water before and after each use. Boiling water for regular coffee normally kills bacteria with its high temperature whereas cold water does not.
