If I remember correctly, there was a tea vendor we talked with once who said aged teas were better for older people. I suspect that may be because they were more gentle on the stomach.
@SlowRain Yes, I think that's true. I guess the reason I didn't mention this in connection with gut comfort is that aged teas are *expensive*.
@babelcarp I go about it mostly the other way round. I default to teas that are neutral or helpful for the gut: ≥ 14% oolong, roasted oolong, shu pu'erh, liu bao, white with some years on it. If I think I need something especially helpful, I'll get out a particularly digestive tea, like an aged sheng or an older one of the darker teas I mentioned.
I drink young or middle aged sheng, green oolongs, and young whites only when I feel particularly up to it. Which is pretty often to be fair.
