Cold brew is where the Venn diagram of lazy and awesome meet: little effort for a result that is flavourful, never bitter and often even better than the hot version.
You need to know how to make this if you want to be prepared for summer.
For 1 litre:
Pour 2 tbs of loose tea into a 1 litre mason jar, then fill with cold water. Cover tightly with a screw-top lid and shake well. Place in your fridge for 5 hours or overnight. Strain and enjoy!
