Mars Iwai 45 Blended Whiskey 750ml

Experience the rare depth of Mars Iwai 45 Blended Whiskey, a Japanese spirit where every grain and malt component matures independently for a minimum of forty-five years before final blending. Crafted at Mars Whisky’s Nagano Prefecture facility, this bottling pairs extensively aged grain whisky with a precisely matched single malt. Four decades inside previously seasoned oak allow lignin-derived vanillin, breakdown sugars, and toasted tannins to integrate slowly, naturally softening initial alcohol sharpness while building a balanced structure. The liquid receives neither chill filtration nor synthetic coloring, maintaining its original viscosity and natural clarity.

Surviving 45-plus-year-old casks are exceptionally scarce, which restricts annual production and global distribution. Each 750 ml bottle features a unique batch code, so slight concentration variations between lots signal standard evaporation differences and cask micro-environment factors rather than formulation changes. This level of provenance suits deliberate evaluation and collecting. To extract the intended profile, pour a 45 ml measure into a tulip or Glencairn glass and rest it for one minute at 20–22°C before nosing. Introduce exactly four drops of room-temperature still water only if surface tension mutes heavier esters. Keep unopened stock upright in a cool, dark area to prevent cork drying and preserve the settled spirit equilibrium.
