Omachi is a sake that is carefully aged in Choryu's underground low-temperature storage facility, bringing out the inherent "unique umami" of sake more than ever before. Aging in bottles for a long period in an underground cellar with little temperature change allows the complex flavors to blend together, resulting in a mellow sake with a lingering aftertaste. This is a brand that can be enjoyed over time as the temperature changes, whether it's chilled, at room temperature, or warm.
