You can cold brew high end teas to massively reduce bitterness and bring out a lot of the more subtle flavors. I do this with oolong tea and drink that all day at work. I used to drink a ton of soda and this helps me mellow that a lot. I was hitting a large Baja blast just about every day with lunch, then I found out my cholesterol was high and now I try to only go once or twice a month. Still love Baja, but the sugar really sets in my mouth now and feels sticky and gross afterwards.
