This "Yuzamashi Chawan (Cooling Bowl)" is a tool designed to cool boiled water to the optimal temperature.
By lowering the water temperature before brewing tea, you can enhance the delicate flavor and overall deliciousness of the tea.
Matcha and Green Tea Require Optimal Water Temperatures
When brewing matcha or green tea, it is not recommended to use boiling water at 100°C (212°F) directly. The temperature of the water plays a crucial role in bringing out the best flavor of each tea.
This is because the tea's flavor components are extracted differently depending on the water temperature. For instance, catechins, which contribute to astringency, are more soluble at temperatures above 80°C (176°F), while amino acids, which contribute to the tea's delicate and rich flavor, are better extracted at lower temperatures around 50°C (122°F).
In other words, the optimal water temperature to control the astringency and enhance the flavor of tea varies as follows:
Matcha: 80–90°C (176–194°F)
Sencha: 70–80°C (158–176°F)
Gyokuro: 50°C (122°F)
On the other hand, teas where aroma is the main characteristic, such as black tea, oolong tea, and Japanese teas like genmaicha or hojicha, taste best when brewed with boiling water at 100°C (212°F) to fully extract their aromatic and astringent components.
Due to the nature of ceramic products, there may be occurrences of iron spots, pinholes (small holes resembling those made by a fork), glaze imperfections, uneven coloring, variations in shade, minor scratches, slight distortions, or minor wobbling. These are within the acceptable standards for quality and are not considered defects. Please understand these characteristics before making a purchase.
After use, clean the ceramic item with dishwashing detergent to remove any stains, and ensure it is thoroughly dried before storing. Inadequate drying may cause mold, stains, or odors to develop.
Since ceramics are made from coarse clay particles, do not drag the item across surfaces such as tables. Doing so may cause scratches on the table or surface.
Do not expose ceramic items directly to open flames, such as on a stovetop, or use them in an oven.
