A Prime Example of Shokuchushu (食中酒) Advocating 'Tanrei Umakuchi (淡麗旨口)'
Niigata sake is known as a synonym for 'Tanrei Karakuchi (淡麗辛口)' (light and dry), but Hakkaisan, among them, champions the concept of 'Tanrei Umakuchi' (light and flavorful). It is characterized by a good balance, offering a clean and light mouthfeel while still allowing the rich umami derived from rice to be fully appreciated. It is designed to add depth to a Tanrei flavor profile.
This exquisite balance, which enhances the flavor of food without losing its own presence, has led to its reputation as a 'shokuchushu' that pairs well with a wide variety of dishes.
A Beloved Classic Jizake (Local Sake) in Restaurants Nationwide
Among the many jizake from Niigata, Hakkaisan has a particularly high distribution volume, making it a brand frequently seen in izakayas and restaurants across the country. Its ability to combine an approachable price point with quality, making it suitable not only for special occasions but also for everyday drinking, is one reason for its long-standing support.

One of Hakkaisan's representative grades is Tokubetsu Honjozo-shu (特別本醸造酒). It is made by adding a small amount of brewer's alcohol to rice with a high rice polishing ratio (精米歩合) to refine its aroma and flavor. It is characterized by a clear, clean taste free of impurities and a crisp finish. Lighter than Junmai-shu (純米酒) and with a milder aroma, its appeal lies in its ability to not overpower food.
