Using French Press for Coffee Cold Brewing

Using a French press to cold brew coffee is pretty easy. We got ours in IKEA but I'm pretty sure any French press will do.

The ratio of water to coffee per mass we use is 7:1. One has to increase the amount of coffee to account for the lower caffeine content extracted by the cold brew process. Considering that the approximate mass of water is somewhat around 1KG per 1L, 7:1 ratio means around 140 g of coffee per 1 L of water.

The plunger in our model can only go a certain way down, and it's a small press so there was some adjustment required. Since we have a kitchen scale it wasn't too hard to measure. The results are in the recipe below. Enjoy.

Cold brew coffee in a french press

Cold Brew

Ingredients

  • 70 gram ground coffee.
  • 0.5 liter (chilled) water.

Instructions

Put the coffee in the French press and pour water over it. Stir with a spoon to make sure that the coffee is equally distributed in the water. Cover the French press and put it in the fridge for a minimum of 12 hours. After that period, remove from fridge and filter out the coffee with the plunger. The resulting liquid is cold-brewed coffee that you can dilute afterwards and optionally heat it. We have ours with soy or oat milk. The recipe is enough for a few cups to get you through the day, but you will probably adjust accordingly.
