Tasting Notes

Assemblage 4 is an expressive, multi-layered Junmai Daiginjo that feels both structured and surprisingly buoyant on the palate. Aromatics open with refined fruit and herbal lift, then broaden into a more complex spectrum that can evoke nutty tones, subtle florals, and savory depth as the sake breathes. The texture is sleek and expansive, with an energetic, wine-like sense of movement that carries through a long, composed finish. This is a sake built for nuance and evolution in the glass, vivid at first pour, then increasingly detailed with time.

Overview

IWA 5 is shaped around the idea of “assemblage”, blending distinct sake components to achieve a single, precise expression. Assemblage 4 (2022) continues that approach with a carefully orchestrated build: multiple rice varieties and yeast strains are used to create contrasting layers, then brought together through blending to form a cohesive whole.

This release is Junmai Daiginjo with no added alcohol, and the entire production is pasteurized, making it stable yet still highly aromatic and dynamic. It is also designed to be explored across temperatures: chilled for clarity and lift, room temperature for depth and breadth, or gently warmed for a rounder, more savory expression.

Best Served: Chilled, Room Temperature, or Gently Warmed

Food Pairing: Grilled seafood, shellfish, roast chicken, mushroom-forward dishes, and umami-rich plates that can handle both aromatic detail and palate weight.
