I actually forgot I had this until I found it in the refrigerator a couple days ago. It is still good but I decided I wanted to cold brew it as an experiment. I think I liked it better hot, when it was cold it reminded me a bit too much of spinach juice. I found some freeze dried blueberries last night at Whole Foods (“Just Blueberries”) and I threw those into the cold brew last night. This morning my green tea is slightly purple and has a very light blueberry flavor. Might have to repeat that experiment again with a less vegetal tea like a white tea.
