Make super-strength java with the Espro CB1 Cold Brew Coffee Kit. This set can actually make up to 48 ounces of cold brew concentrate. That is the super-strong stuff you mix with water or milk, depending on your preference. This cold brew making setup includes three items: two filters and a growler. Sure, you can make cold brew with less advanced gadgets, but this one ensures an accurate brew that’ll go down nice and smooth. Thanks to its auto-lock valve, the CB1 ensures a spill-free brew. What’s more, the growler reseals with ease so you can use it again and again. As the filters come in black or stainless steel, you’ll be able to pick one that matches your aesthetic.
