Glad to see these gems are arriving to happy recipients! Most USA recipients should receive them by Monday. International ... well, the German participant might wait longer than destinations much further away. Simple brewing directions. These are also located on page 1 near the beginning of this topic for easy finding.
1:1 ratio (1 gram per 1 ounce/30 ml water) seems to be a good starting point, though I am still experimenting. I am certain these can take higher ratios (more leaf).
Preheated teapot, pour the leaves in seconds before pouring water back in ... AND remember to smell the dry warming leaves. The Tenryu, I sort of swirl the dry leaves around to release aroma.
Water, 158-160* (70* C). I liked it around this temp for this ratio, but perhaps cooler for higher ratios.
Tenjo 60 seconds, Tenryu 90.
Successive steeps, 165* for 15-30 seconds. 3rd hotter for 60, 4th HOTTER for LONGER. If you go for more steeps, I likely do not have to tell you.
