An ultimate expression of sweetness, intensity, and innovation.
Seto Ashigarigo Zerogo Mugen FF (Fortissimo) is the boldest evolution of the Ashigarigo series—crafted without compromise to push flavor to its absolute limit. Built upon the concept of “Zerogo ∞ (No. 0 Infinity)”, this sake is a continuous pursuit of perfection, drawing out the full potential of rare hydrangea flower yeast native to Kaisei Town.

Using the groundbreaking Jōjō-shikomi (Layered Brewing) method, sake—rather than water—is layered into the fermentation process. Unlike traditional Kijoshu, the goal here is not heaviness, but vibrant fruit expression, luminous sweetness, and refined elegance. The result is a sake of extraordinary depth and clarity, with a lush yet polished profile that has captivated chefs and sommeliers worldwide—many calling it one of the most delicious sakes they’ve ever tasted.
