Extraordinary. I LOVE that Old Dong Ting, it's so rich and roasty and
balanced and friendly. I'm going to try your mineral water experiment first
thing.

Putting the technical chemistry aside because it ain't my thing, are you
saying that you added a bit of mineral water *once* and its effect persisted
through steeps, even after rinsing? That the bit of mineral water affected
the tea leaves *and* your tastebuds? Anyway, I'll be experimenting soon.

"Perceived," eh? Well that's good enough.
