A sake brewery is a facility where sake, a traditional Japanese rice wine, is produced. The brewing process involves fermenting polished rice, water, yeast, and a mold called koji. This combination creates a unique beverage that varies in flavor, aroma, and alcohol content. In a sake brewery, skilled artisans oversee each step, from rice preparation to fermentation and bottling. The environment is carefully controlled to ensure optimal conditions for brewing. Many sake breweries also offer tours and tastings, allowing visitors to learn about the history and craftsmanship behind this beloved drink.
