Water & Terroir

Sake Is 80% Water

Approximately 80% of sake by volume is water. The mineral content, pH, and purity of the water used in brewing fundamentally shape the character of the finished sake. "Where there is great water, there is great sake" — this saying holds as true today as it ever did.

Hard vs. Soft Water

Hard water contains higher concentrations of calcium and magnesium, which accelerate fermentation and tend to produce bold, dry sake with a sharp finish. Soft water, with fewer minerals, ferments slowly and gently, producing soft, smooth, rounded sake. These two poles define the two great styles of Japanese sake.

Nada's Miyamizu — The Source of "Otoko-zake"

The breweries of Nada (in Kobe's Higashinada district) draw from "Miyamizu," a hard water filtered through layers of granite from the Rokko mountains. Rich in potassium and phosphorus, it drives vigorous fermentation, producing the dry, powerful "men's sake" (otoko-zake) that made Nada famous. Kikumasamune, Hakutsuru, and Kenbishi are among its greatest expressions.

Fushimi's Gokosui — The Source of "Onna-zake"

Kyoto's Fushimi district is blessed with "Gokosui" (Imperial Fragrance Water), a soft water selected as one of Japan's finest. The sake it produces is known as "onna-zake" — women's sake — for its gentle, pliant character. Gekkeikan and Saito Shuzoen (Eikun) are hallmarks of this style.

Niigata's Snowmelt

Water that falls as snow on the Echigo mountains slowly percolates through rock over years, emerging as ultra-soft, iron-free groundwater. This exceptional water — minimal in minerals, pristine in purity — enables the "tanrei karakuchi" (light and dry) style that defines Niigata sake. Kubota, Hakkaisan, and Koshino Kanbai owe their clarity in large part to this water.
