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.
