Iwa 5 Junmai Daiginjo Sake Assemblage 2 (720ml)

$22999

Created by Richard Geoffroy—the man who spent nearly three decades as chef de cave at Dom Pérignon—IWA 5 brings Champagne's philosophy of assemblage to Japanese sake. Assemblage 2 blends three rice varieties (Yamada Nishiki, Omachi, and Gohyakumangoku) with five different yeasts, including two wine yeasts, to create a sake of unusual width and complexity. Polished to 35%, qualifying as junmai daiginjo. Geoffroy describes Assemblage 2 as sake that drinks 'as white wine'—a bridge between two great fermentation traditions.

More about

Richard Geoffroy, who oversaw wine production at Dom Perignon for multiple decades, discovered sake and he fell for it hard. So hard that he left the job then any of the rest of us would kill to have. IWA is now his full time passion.

His sake is called "IWA 5", and it is produced at a Kura (brewery) nestled among the gentle mountains of the prefecture of Toyama. Through precise orchestration, five classes of elements are brought into unison -- hence the "5": rice origin (terroir), rice varieties (there are three), yeast varieties (there are five), yeast production methods and fermentation methods. Place, raw materials and methods are all designed to create a world class sake that meets the standards of someone who has produced luxury beverages all his life.
