Actually, the resulting liquor from the taller glass has visible floating leaf particles that got through my scalloped wood spoon acting as lid - also used to mimic grooved slots found in some shiboridashi. The more horizontal glass didn’t release as many visible leaf fragments into liquor that was dispensed, they stayed at bottom of glass. There are probably finer leaf particles in the richer steep though. But even so, looking at tall glass vs horizontal glass with water steeping something else seems to be going on as well. Some leaves are still floating at the top of water while steeping after 1+ minute in tall glass. You mentioned above that the narrow raked grooves found in some shibo hold back the leaves, actually the lid holds leaves back in a shibo, with the grooves allowing liquor to pass through.Baisao wrote: ↑Wed May 29, 2019 6:36 pm4) As noted in Victoria's experiment, there are more particulates in the horizontal sample than the vertical sample. Some of this is due to settling of the mixture but some of it is also do to the secondary filtration of the tea is the liquor is strained through leaves that have collected at the spout. If the tea has more particulates it will contribute to a fuller body.

Baisao, I’m curious now since you like using a few vertical kyusu: If you have two kyusu that are the same clay -just one more vertical vs the other more horizontal in form -what resulting differences have you found in steeped liquor?
