- 500 g ground coffee ground 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
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 gas is released from coffee when mixed with water and especially if the coffee is very fresh)
Close lid and let sit at room temp for 20-24 hours at room temperature.
Strain through a fine mesh strainer and store in glass bottles in the fridge. 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 usually wait until it has been in the fridge for a while and the sediment falls to the bottom of the bottle.
Set it in the fridge for up to 4 weeks. Serve over ice with milk, oat-milk, almond milk or coconut milk. If you would like extra sweetness (although cold-brew is naturally pretty sweet) then add a bit of simple syrup. Enjoy!
