Tatenokawa Junmai Daiginjo Komyo Dewasansan | 1% Rice Polishing World Record

Breaking the Limits of Sake History | The Once-Impossible "1% Seimaibuai" Miracle

The ultimate challenge of a new era in Japanese sake — once considered a dream beyond any brewery's reach: 1% seimaibuai (rice polishing ratio). Tatenokawa Brewery has always devoted itself to Junmai Daiginjo, and to redefine the true value of sake, the brewery partnered with local contract farmers to select Yamagata's signature rice "Dewasansan". After months of slow milling, every grain is polished down to a mere 1% core (99% removed).

Shattering the myth that ultra-polished rice produces thin sake, this expression reveals an extraordinary transparency and profound umami depth — crystal-clear yet richly layered. This is no mere sake; it is a liquid artwork carrying the soul of master brewers, redefining what sake can truly be — a rare treasure for sake collectors, connoisseurs, and the most prestigious business gifting.

Core Brewing Character | A Sake World Record

• World-Record 1% Seimaibuai:An unprecedented milestone in sake history — 99% of the grain polished away to leave only the 1% core. Tatenokawa is the only brewery in the world to achieve this
• Yamagata's Signature Dewasansan Rice:Hand-picked Dewasansan from contract farmers in Yamagata, slowly milled over months — expressing the purest character of Yamagata terroir
• 0.1°C Precision Brewing:Brewed with 0.1°C-precision temperature control in small hand-crafted batches, ensuring every bottle reaches the ultimate quality

Tasting Notes

• Nose:Crystal-clear and luminous, opening with pure white florals, green apple, white peach, and a delicate molasses note
• Palate:Silky and refined, mid-palate revealing Dewasansan's profound umami, honey, and pear sweetness over crystalline minerality
• Finish:Long and pure, with lingering white florals and a sweet rice undertone — the soul of liquid art expressed

Recommended Serving

• Chilled (5–10°C):The ideal serving temperature for Junmai Daiginjo — fully expressing Dewasansan's delicate florals and umami
• Wine Glass Service:A white wine glass (rather than an ochoko) better releases the layered aromatics
