IWA: The Art of Assemblage
An Intimate Omakase Experience at Kosen
May 8th | Hosted by IWA Representative, Brenton Blanchard
Kosen invites guests to a multi-course omakase paired with a curated selection of IWA Assemblages, including the newest release and the rare IWA Reserves.
Created by Richard Geoffroy, former Chef de Cave of Dom Pérignon, IWA is born from a singular vision: to apply the philosophy of fine wine — blending, vintage identity, and bottle maturation — to Japanese sake.
Throughout the evening, guests will experience a progression of IWA expressions. This is a rare opportunity to encounter IWA in its full arc — expressive, layered, and composed — within the refined setting of Kosen.
