“Ash” is a refined expression of Aramasa Brewery’s commitment to tradition and innovation. Crafted using the kimoto method—a traditional technique that cultivates natural lactic acid bacteria—it produces a sake rich in umami and acidity. Fermentation in wooden vats imparts a subtle depth, influenced by the native microbes and aromas of the wood. This sake is brewed with the historic No.6 yeast, originally discovered at Aramasa and now legendary in the world of sake. Upon opening, it presents a clean, structured acidity and a sharp impression. Over time—after a few days or even weeks in refrigeration—its flavors evolve, gaining roundness and complexity as the balance between acidity and sweetness harmonizes. The result is a quietly powerful sake, embodying the spirit of lingering strength after the fire, just as its name suggests.
