One cup, or the whole afternoon. Your call. How do aging and fermentation change the taste of tea? Taste young Wawee raw puer, the tobacco-and-hay 2013 Love Forever, a woody raw puer, and a complex 20-year ripe puer cake made in China from Thai-grown leaves.

Free tasting at 4Seas Nimman, 1st floor, out the back on the terrace. No lecture or ceremony. Come any time before 4 pm; you need not stay until the end. Please bring some food to share and water if you get thirsty. Please don’t bring tea.
