Oolong

How to brew High mountain oolong

Taiwanese gaoshan: Alishan, Lishan, Shan Lin Xi.

Tightly rolled balls need hot water and a longer first steep just to open. Once they've unfurled, the next two steeps can be shorter.

The details

Rinse

Not needed. Start with the first steep.

Drinking window

Best fresh: at its best for about 6 months once opened. The floral top notes are what fade first.

Caffeine

Contains caffeine. How much depends on the leaf, the water temperature and the steep time; the style alone is a poor guide.

Iced and cold brew

Cold brew: 1.2 g per 100 ml of cold water, in the fridge for about 8 hours. Keep it cold and drink it within a day or two. For iced tea now, brew a concentrated hot cup (the same leaf in half the water) and pour it over an equal weight of ice; Steepdial accounts for the ice in the total water.

How Steepdial adjusts

After a session you tap what you'd change: more flavor, less bitter, less drying. Steepdial changes one thing at a time, staying near the ranges above, and remembers what worked for that tea.
