Each Assemblage of IWA 5 keeps true to Sake, yet departs from convention
in many aspects

First and foremost, the global expression of classical Sake is shifted to a greater equilibrium between nose and palate. Palatability is key, actual IWA 5’s main asset. A major emphasis is put on the finish. The aftertaste lingers and remains the memory of the Sake, satisfying, refined and smooth: a unique combination of vibrant aromatics, of the sweet, the bitter, the sour, the spicy and the umami.

The journey of creation:
Assemblage 4

Our new Assemblage 4 took Founder-Maker Richard Geoffroy on his own journey into the soul of IWA – finally making it at the Kura in Toyama, in the serenity of the doma symbolically positioned between the rice fields and the brewing vats. IWA keeps pushing the envelope. The three-weeks of the Assemblage process resulted again in evolution, one further exploring the direction developed from A1 through A4, a step completed in the spirit of singularity, sophistication and intricate layering.


Sophisticated, bodied yet weightless,with great dynamics.Assemblage 4 gracefully unfolds in aseamless array of sensations.

The nose
As the sake breathes in the glass, time pauses for the emergence of marzipan and lotus root. While intensifying, the initial aromas are completed by vibrant marine undertones, followed by coconut and darker tones of hazelnut and shiitake. A profound flourish of violets is a surprising conclusion.

The palate
In total coherence with the nose, the palate embarks on a ride of fluid transitions. It dances through an airy softness, a playful fusion of fruity, floral, and subtle maritime notes. This sophisticated dissolve reaches its crescendo through a lingering aftertaste, highlighting IWA’s signature of white and Sancho peppers.

IWA 5 has an intriguing capacity to pair with a great array of foods: the Sake has sort of a flexibility to invariably adjust itself right to the level of the food, sensibly, from the delicate to the robust, from light to dark flavors. IWA 5 can pair with successive dishes throughout one single meal.
