月の井酒造店 生酛純米原酒チヨニシキ｜注目のヴィナイオータ米で醸す日本酒

This article provides an in-depth review and buying guide for a truly unique Japanese sake: a Kimoto Junmai Genshu brewed at Tsukinoi Sake Brewery in Oarai, Ibaraki Prefecture, Japan, using Chiyonishiki rice cultivated by the agricultural division of Vinaiota, one of Japan’s most respected importers of natural Italian wines. Vinaiota, led by Hisato Ota, has long championed the philosophy that wine should reflect the land, the producer, and the raw materials. This philosophy extends beyond Italian wine into an unlikely partnership with a traditional sake brewery in the Ibaraki region of Japan. The rice variety used is Chiyonishiki, grown by Vinaiota’s own farming team in Ibaraki Prefecture. This variety is known for producing harder grains, a characteristic that was further intensified by high-temperature damage during the growing season. The milling rate was kept at 70 percent, meaning 30 percent of the outer layer of each grain was polished away, leaving a substantial amount of the original grain intact. This low milling rate is more typical of everyday drinking sake rather than premium ginjo styles, and it contributes to a fuller, more robust flavor profile. The brewing was overseen by Tatsuya Ishikawa, the toji or chief brewer at Tsukinoi Sake Brewery. Ishikawa employed the kimoto method, one of the oldest and most labor-intensive techniques in sake production. In kimoto brewing, the sake mother or shubo is developed using naturally occurring lactic acid bacteria rather than commercially produced lactic acid. This process takes considerably longer than the modern sokujo method and introduces a complex array of microorganisms into the fermentation, resulting in sake with greater depth, complexity, and often a more pronounced acidity. Furthermore, this sake was brewed without the addition of cultivated yeast, relying entirely on the ambient yeast strains present in the brewery environment. This approach mirrors the philosophy seen in natural winemaking, where minimal intervention allows the terroir and indigenous microflora to express themselves in the finished product. Despite expectations that the hard rice would lead to a slow, difficult fermentation and a rough, unrefined sake, the actual brewing process defied all predictions. According to the product description, fermentation proceeded with surprising speed and smoothness. The freshly pressed sake displayed remarkable balance and an outgoing, approachable character that astonished both the toji and the Vinaiota team. The finished product from the R5BY brewing year, corresponding to the 2023 harvest, is described as possessing a quality of refinement and propriety, with descriptors such as well-behaved and elegant being used to characterize it. This stands in contrast to what one might expect from a sake with such an unconventional pedigree. The sake is bottled as a genshu or undiluted sake, carrying an alcohol content of 19 percent. It is muroke, meaning it has not been charcoal filtered, preserving the full spectrum of flavors and aromas. It has been pasteurized with a single fire treatment, which stabilizes the sake for storage at room temperature while retaining much of the freshness and vibrancy of the unpasteurized version. The combination of high alcohol, low milling, and kimoto brewing creates a sake with substantial body and structure. In terms of food pairing, this full-bodied junmai genshu pairs well with richly flavored dishes. Japanese cuisine options include simmered buri daikon, braised chicken and root vegetables known as chikuzenni, and grilled miso preparations. Western pairings might include braised pork belly, roasted duck, or beef stew. The sake also complements fermented foods such as nukazuke pickles, kusaya dried fish, and shiokara salted seafood, whose umami richness echoes the complexity of kimoto brewing. Cheese lovers might enjoy pairing this sake with washed rind or aged hard cheeses, a natural bridge between the worlds of Italian food culture and traditional Japanese brewing. The sake is available for purchase from Toscany Italian Wine Specialty Shop on Rakuten Market at a price of 3960 yen including tax for a 720ml bottle. Free shipping is available when purchasing six or more bottles from the shop, and the product can be shipped at room temperature alongside wine and other shelf-stable food items. It is also listed on the Vinaiota official online shop and has been seen on Amazon Japan. Due to shared inventory across multiple sales platforms, stock availability may fluctuate, and potential buyers are encouraged to check availability promptly. The importer and distributor is Vinaiota Co., Ltd., the same company responsible for cultivating the rice used in this sake. What makes this product particularly noteworthy is the bridge it creates between the natural wine community and the world of traditional Japanese sake. Many natural wine enthusiasts in Japan have developed an appreciation for sake that shares similar values of minimal intervention, terroir expression, and artisanal craftsmanship. This collaboration between Vinaiota and Tsukinoi Sake Brewery represents a tangible expression of those shared values, offering a sake that appeals to both traditional nihonshu drinkers and adventurous wine lovers seeking new experiences. The Chiyonishiki rice variety, while not as widely known as Yamadanishiki or Gohyakumangoku, brings its own distinctive character to the sake. Its harder grain structure, combined with the challenges of the growing season, created conditions that tested the skill of the brewing team. The successful outcome is a testament to the expertise of toji Ishikawa and his ability to adapt traditional techniques to unusual raw materials. For those interested in exploring the intersection of wine culture and sake culture, or simply seeking a well-crafted kimoto junmai genshu with an fascinating backstory, this offering from Tsukinoi Sake Brewery and Vinaiota is well worth seeking out. It embodies a philosophy of respect for ingredients, trust in natural processes, and the belief that great beverages are born from the collaboration between dedicated growers and skilled artisans.
