I like cold brewed coffee. I find it much smoother than hot brewed. Bit of a faff to make though. You can do it as 1:8 coffee to water and leave it in the fridge for a couple of days shaking the container occasionally. After filtering the grounds out it’s ready to drink. However I usually make it 1:1 to make a coffee concentrate then I can dilute to taste with hot or cold water. I do like it strong.
