Do you like homemade cold teas? Then Hario bottles are made for you! Perfect for a successful Cold Brew, these elegant glass bottles are specially designed to make your life easier. Simply put the loose tea of your choice at the bottom of the bottle, fill it with fresh water and let it steep for a few hours at cold (or room temperature if you want to speed up the infusion) then serve directly. A filter incorporated in the cap allows you to filter the leaves when serving without using a strainer. We recommend steeping for a minimum of 3-4 hours. You can leave it to infuse for longer as cold infusion is a very gentle process, in this case you just have to be careful not to add too much tea.
