This thread got me thinking about a crazy tea session I had a few months ago. When I left Korea to travel, my teacher made me a special goodbye pot of my favorite tea: 1997 Yellow Stamp Iron Cake (pretty pricey, though this company sells it around 1/2 of what other places sell similar tea), which we normally brew with 7 grams in a 140cc, 90s-clay, master-made zini pot (my teacher's favorite pot).
For this session, knowing I like my tea strong, he threw in about 20 grams! Amazingly, it was still delicious, which speaks well to the tea, the pot, and the maker. After 15 or 20 infusions, it was starting to taste like what it would normally taste like on the first steep! Fantastically delicious as that session was, we had stomach aches afterwards, and I don't know the last time I was THAT jacked up on puerh! Learned more about the tea though. All in all, good experience.
