Unlock the full potential of your tea with this essential Yuzamashi (water cooler). Transferring boiling water into this vessel immediately drops the temperature by 5-10 degrees Celsius, allowing you to reach the ideal brewing range for premium leaves. Since Sencha flourishes at 70 degrees Celsius and Gyokuro requires a delicate 40 degrees Celsius, this tool is vital for extracting maximum umami without the bitterness. It serves as a must-have item for anyone seeking the authentic taste of Japanese tea. Please note that Yuzamashi crafted by Gyokko feature a unique "Gyokko" stamp rather than the standard "Gyokko" mark found on his teapots. Gyokko KilnMaster artisan Umehara Gyokko II handcrafts each piece at the renowned Gyokko Kiln. Both the second and third generations of the Gyokko family are certified Traditional Craftsmen, ensuring world-class quality in every vessel.

The natural kiln-firing process creates unique color variations, meaning your product may differ slightly from the images shown.
