Love the refreshing taste of cold brew iced tea in the summer? The Hario Aisne Filter-In Bottle is a new way to prepare delicious and refreshing cold-brew tea or fruit infusions. The bottle holds up to 800ml of cold brew tea, which is incredibly straightforward to make. Just pop your favourite loose-leaf or bagged tea into the bottle, add cold water, and refrigerate! The resulting brew is smooth and richly-flavoured, without the bitterness that tends to result from over-extraction at high temperatures. A plastic clever filter keeps your tea clear from stray leaves in the final cup without the need to remove it.
