The Pure Winter Sip: What Kanno Mizu and the Tea Ceremony Teach Us

The “Kanno Uchi” period, from January 5th to February 3rd, is the coldest time of the year, a special season where we can feel the pure blessings of nature. The “Kanno Mizu” (winter water) drawn during this period is revered in tea ceremonies for its clarity and strength.


The Appeal of Kanno Mizu


“Kanno Mizu” refers to well water or spring water that emerges during the cold winter months. The water, naturally filtered in the winter chill, is said to be free from impurities and exceptionally smooth to the taste. Using this water enhances the flavor of matcha, deepening its taste.


Historically, tea masters have regarded Kanno Mizu as “water of longevity” or “medicinal water,” carefully collected and used in tea ceremonies. This practice embodies gratitude and respect for the gifts of nature.


The Role of Water in Tea Ceremony


Water is at the heart of the tea ceremony. The quality and temperature of the water used in the kettle significantly affect the flavor of the tea. Particularly, Kanno Mizu, with its coldness, brings out a smoothness when boiled, accentuating the aroma and flavor of matcha. Additionally, the purity of this water contributes to the refreshing atmosphere of the tea ceremony.


Words like “Kansui Seisei” (clear winter water) may be chosen for the hanging scroll, expressing the purity of water and the winter spirit. This phrase means “water that reaches its utmost clarity in the cold,” reflecting the beauty of nature within the harsh season.


Incorporating the Spirit of Kanno Mizu in Daily Life


Kanno Mizu teaches us the importance of appreciating the blessings of nature and incorporating a sense of purity into our daily lives.

Drinking warm water in the crisp winter air: Savoring carefully brewed hot water or tea on a cold winter morning helps restore balance to the body and mind.

Being selective about water: Choose spring water or soft water, rather than tap water, to prepare your tea. You’ll notice a remarkable difference in flavor.

Adjusting water temperature: For matcha made with Kanno Mizu, a slightly lower temperature of 70–75°C is ideal. This enhances the delicate aromas and flavors.
