12-piece Taiwanese stemware set (6 short glasses and 6 tall glasses), crafted from fine white porcelain.
 
This set of glasses is a classic in Taiwan, it was invented by Taiwanese tea masters to facilitate the appreciation of the volatile aromas of tea. The elongated glass helps to retain these aromas for longer compared to common tea glasses. Something similar happens when tasting wine, since elongated glasses are also used for the same purpose.
 
The tall glass is used to first pour the tea, which is then poured into the short glass. The aromas of the drink will remain in the tall glass, which you can enjoy by bringing it close to your nose. This intensifies the tea drinking experience, directly using the olfactory receptors.
 
Because these cups are made of porcelain, they are suitable for tasting any of the 6 varieties of tea.
