I decided to cold brew the last of this tea. I was planning on having it at supper time, so I put it in the fridge before I went to work in the morning. But I got storm stayed out of town so it ended up brewing for about 32 hours. I was a bit worried when I took the strainer out becuase the liquor was a deep, dark, maroon colour. It was quite bitter, but I added extra sugar, about 1/3 cup, and it turned out to be delicious. I would not normally cold brew for this long, but in the end it turned out good.
