Bitter-phobe, here. My tolerance is better than it used to be. I can take a hint of bitter as in some young sheng puerhs, if it is balanced with a lot of sweet, but my tolerance overall remains pathetically low.
Drinking some purple bud Haiwan puerh today. Some terrific infusions, and some that were just ok. Started the day with a mystery white tea that was a gift to a tea-friend, quite a lovely delicate thing.
