Though single-serve, bagged tea varieties have come a long way over the last few years, we're partial to a loose-leaf brewed cup. Resembling a handsome piece of chem-lab glassware, this clever steep kit by Paper & Tea brews two cups of your favorite blend, using a clever filter to keep loose bits out of your cup while allowing leaves to float and infuse freely. And since it's the perfect size to fit on a shelf in your fridge door, you can use it to cold-brew tea as well — ideal for cocktails and warm-weather sipping.
