A newly designed glass cold brewer from Hario.
All you do is add some tasty, medium-ground coffee to the mesh filter, fill with cold water, and leave it in the fridge for a few hours or overnight.
The result? Smooth, syrupy sweet light coffee for you to pour (into your KeepCup, obviously), and run out the door. One taste, and you'll be as hooked as we are. We might not even put it back in the cupboard when winter comes!
