Finally I realized I needed to have a tea I knew the flavor of to test my water. I was feeling not like a fruity tea, and I realized chocolate sounded great. Looking back on my old notes I reminded myself that I thought this one was slightly weak at 1 TBSP for 12oz, so I went for 1.5 TBSP this time.
Turned out pretty great! It was suuuper sweet this time, very chocolatey, and nicely like toasted rice. I think it kind of drowned out the minerally oolong, which works for me. I am definitely happy to drink this up (and I think my water is fine now).
