Tezumi Haikake Yuzamashi

A yuzamashi is a traditional Japanese water cooler designed to lower the temperature of boiling water to the ideal range for brewing delicate green teas like gyokuro or sencha. Pouring boiling water into this vessel helps dissipate heat quickly, ensuring you do not scorch the tea leaves.

The vessel is designed to be held by the sides, which remain cooler than the water inside. Because you are using it to cool water down to a brewing temperature—typically between 140°F and 175°F—the exterior is comfortable to handle during the pouring process.

Tokoname-yaki pottery is renowned for its high-quality clay and precise craftsmanship. The ceramic material provides excellent heat retention and stability, while the specific ash glaze adds a unique aesthetic that develops character over time with regular use.

While its primary function is cooling water for tea, its wide, open design and precise pouring lip make it an excellent small serving pitcher for sauces, dressings, or even as a unique vessel for sake service.

To preserve the finish, hand wash the yuzamashi with warm water and a mild, non-abrasive soap. Avoid using a dishwasher, as the high heat and harsh detergents can damage the delicate ceramic and glaze over time.
