In recent years, demand for small to medium-sized bottles (720ml) has been expanding in the sake market. 720ml bottles account for approximately 40% of purchased sake (*1), and ginjo sake and daiginjo sake are popular among casual and trial drinkers (*2). In light of these market trends, this product aims to be a "high-quality yet affordable daiginjo sake" that can be easily incorporated into everyday meals.

■About "Ozeki Daiginjo Nama Chozoshu 720ml"

Using Ozeki's unique "Hakugin Yeast," we have renewed our Daiginjo as a nama-chozoshu. The freshness of freshly squeezed sake, unique to nama-chozoshu, is harmoniously combined with the apple-like ginjo aroma, resulting in a refreshing, clear, and refreshing taste without any unpleasant aftertaste. You can enjoy a clearer taste.

What is Silver Yeast?

This is Ozeki's original yeast, which was bred and improved over a period of approximately two years at the Ozeki General Research Institute. Using this yeast results in a sake with a high level of ethyl caproate (*3), resulting in a fruity aroma and a clear taste without any unpleasant aftertaste. The name "Silver Yeast" comes from the comparison of the "special moment" brought about by the refined aroma to a magical world of silver.
