Last summer, I drank a lot of cold brew. As I traveled around Europe, it became clear to me that cold brew was trendy and available in many different cities we visited. One of the hotels we visited had a fantastic coffee boutique (to call it a coffee shop would be insulting). These guys were making cold brew by using the slow drip method, and it was delicious.
I found that the simplest way to get a great cold brew at home is to purchase the Hario Cold Brew bottle from Blue Bottle coffee. Making a batch is drop-dead easy.
1. Open bag of ground coffee
2. Place into the mesh basket
3. Close bottle
4. Fill water up to fill line
5. Shake
6. Place in the fridge till the morning
I then take the filter out in the morning and put the bottle back in the refrigerator and drink it throughout the day. I also like that the Hario is made of glass. Many of the contraptions I investigated were plastic.
