Beyond delighted to offer this double-walled glass bottle with a removable infuser basket. Add tea to the infuser basket, fill bottle with hot water and that’s it. Easy, on the go hot tea. Remember, the longer you steep our teas, the more flavorful they are. You can also keep adding hot water all day long which will still provide delicious, albeit more lightly flavored tea. The glass means it is BPA-free and you will experience no aftertaste common with other plastic and metal bottles. Sourced from Mokeeta, a company in Northeast Minneapolis founded by students from the U of M focused on creating sustainable products.
