Miyamizu
宮水
定義
The famous brewing water of the Nada district in Hyogo Prefecture, rich in minerals like potassium and phosphorus that promote vigorous yeast activity. Miyamizu was discovered in the 1840s and is the key to Nada's reputation for producing bold, structured sake.
詳細解説
Miyamizu flows from the Rokko mountain range through layers of shell-bearing sediment that contribute its mineral character. The high potassium content accelerates fermentation, producing the robust, full-bodied style known as otoko-zake (masculine sake). By contrast, the soft water of Fushimi in Kyoto produces gentler fermentation and the softer onna-zake (feminine sake) style. Water analysis — particularly hardness, iron content, and mineral balance — is a foundational consideration for every sake brewery.
