Cold-brewed (about 2 tsp for 450ml) way too long. Like more than 24 hours. It got bitter, which I remedied by adding more water and a little simple syrup to take the edge off. It wasn’t as good as it probably would have been after 8-12 hours brewing, but it still made a fine iced tea. I should get myself a proper iced tea pitcher so I can easily remove the leaves if I don’t want to drink it right away.
