Oolong

How to brew Roasted rolled oolong

Dong Ding, traditional Tieguanyin, roasted high mountain.

Roast and tight rolling both call for the hottest water you can get, and a longer first steep while the leaf opens.

The details

Rinse

Not needed. Start with the first steep.

Drinking window

Keeps well: at its best for about 12 months once opened. Roast settles and rounds out in the months after roasting, so a freshly roasted bag can taste sharper at 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 10 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.
