Yuzamashi (湯冷まし) by Deishi Shibuya

This yuzamashi by Deishi Shibuya is a quietly striking example of contemporary Japanese tea ware that balances rustic presence with refined intention.

A yuzamashi (湯冷まし) is used in Japanese tea practice to cool freshly boiled water to the proper temperature before brewing delicate teas like gyokuro or high-grade sencha. Rather than pouring boiling water directly onto the leaves, the water is decanted into this vessel to drop to the ideal range (often around 50–70°C), allowing sweetness and umami to emerge without bitterness.
