In the UK we're currently experiencing the hell that is summer (I can't cope in temperatures above 20C, mock if you wish) so wanting to get more into cold brew.
Anyone got any recommendations on the best piece of kit to do it?
I just use a French press. My current ratio is 30 grams of coffee grounds to 500ml of water. Mix together, place in the fridge overnight or about 8 hours. Transfer to teapot the following morning so as not to oversteep. Still experimenting though so I'm also curious about other techniques.
