Iwashimizu JUPITER (岩清水 JUPITER)

Iwashimizu JUPITER is a Muroka Nama Genshu positioned at the center of the 'Planetary Series' (Earth, Mars, Jupiter) planned by Igaya Sake Brewery in Nakano, Nagano Prefecture. While the koji ratio of typical sake is around 20%, this product is brewed by significantly increasing the koji ratio to 35%. Using Sankeinishiki rice from Nagano Prefecture and ultra-soft water (hardness near zero), it undergoes a 70-day long-term low-temperature fermentation, chemically engineered to prevent the rice umami from thinning or collapsing even at a low 12% ABV. The structural core of this sake lies in the contrast between the dense umami created by the high 35% koji ratio and the light texture of the 12% ABV. When poured, ester aromatics of white flower, pear, and mild citrus are released. Upon tasting, the transparent and smooth texture unique to ultra-soft water coats the tongue, immediately followed by the intuitive spread of distinct sweetness originating from the koji and rice umami. Beyond the mid-palate, a clear acidity forms the flavor contours, and in the finish, the physical refreshing sensation of the low-alcohol Genshu sharply severs the residual sugar, maintaining a structure that is light yet dense.

Considering the delicate flavor profile of Iwashimizu JUPITER Junmai, I recommend the following pairings: 1. Terroir Pairing: Shirako Ponzu (Cod Milt with Ponzu Sauce): Shirako, a Japanese delicacy, features a creamy texture and subtle sweetness. Jupiter's transparent texture and mild rice sweetness gently envelop the flavor of shirako, while the sake's refreshing acidity cuts through the richness, offering a clean finish. The citrus notes of the ponzu harmonizes beautifully with the sake's citrusy undertones. 2. Bang Bang Chicken (Cold Shredded Chicken) or Chili Shrimp: Jupiter's dense umami created by the high 35% koji ratio structurally combines with the strong seasonings of Chinese cuisine, while the distinct acidity and light ABV (12%) physically wash away the oiliness in the palate.
