A French Press Method for Cold Brew Coffee

June 2nd, 2021

Cold-brewed coffee is totally different from hot brewed coffee, the slow extraction of flavours at low temperature creates a silky drink with mellow notes and extremely low acidity. The good news is that other than amazing freshly roasted Firebat beans: you only need a French press or glass jar.

A Simple Way to Make a Nuanced Cup of Cold Brew Coffee with a French Press

Tip: If you don’t have a French press you can use a jar or pitcher with a lid. You’ll also need a mesh strainer and/or coffee filters!

  1. Grind the coffee beans into a coarse grind – you want the grinds to be about the size of raw sugar.
  1. Combine the ground coffee and filtered water. Gently stir the coffee with the water until all of the coffee gets wet.
  1. Steep the coffee in the fridge. Leaving the French press plunger up, place in the fridge for at least 18 hours or up to 24 hours. Leaving it for less than 18 hours will result in a weaker cold brew while over-brewing for more than 24 hours will start to create bitter notes.
  1. To strain the coffee concentrate using a French press, simply press the plunger down and transfer to another container. For a cleaner brew, pour the coffee concentrate through a coffee filter or a fine-mesh strainer with cheesecloth.
  1. Once strained, transfer the coffee to a clean, airtight bottle or jar and refrigerate for up to 2 weeks. To serve, fill a glass with ice cubes and pour your Cold Brew Coffee over top. Add sweet cream or half-and-half if desired and enjoy!


Undiluted cold brew will last for up to 2 weeks refrigerated; diluted cold brew will last 2 to 3 days refrigerated.

This brewing method may take some time but is worth the wait! Just be sure to use freshly ground coffee beans to get the most flavourful cup of cold brew.
