A Guide to Buying Dassai Sake in the UK for 2026: Understanding 23, 39 & 45
Navigating the world of premium Japanese sake can feel complex, especially when faced with a celebrated name like Dassai. You may have seen the distinctive bottles, each marked with a number—23, 39, or 45—and wondered what separates them beyond the Dassai sake price. Choosing the right one for a special occasion, a gift or simply to enjoy at home requires understanding what these figures represent.
As a Joybuy Product Recommendation Officer, my role is to provide clear, practical guidance to help you make an informed choice. This article will demystify the numbers, explain the unique qualities of each Dassai variation and help you select the perfect bottle for your needs.
How to Choose the Right Dassai Sake
Before exploring our recommendations, here are a few key points to consider when you decide to buy Dassai online.
1. Understanding the Numbers: The Polishing Ratio
The numbers on a bottle of Dassai refer to the seimaibuai, or rice polishing ratio. All Dassai sake is classified as Junmai Daiginjo sake, the highest grade, which means it is made with only rice, water, yeast and koji, with no added alcohol. For this grade, the rice must be polished to at least 50% of its original size.
Dassai takes this to another level.
- Dassai 45: The rice is polished until only 45% of the grain remains.
- Dassai 39: Polished further, leaving 39% of the grain.
- Dassai 23: An exceptional level of polishing, leaving just 23% of the rice core.
A lower number signifies more of the outer grain has been milled away. This process removes fats and proteins that can cause off-flavours, resulting in a purer, more aromatic and refined sake.
2. The Significance of Yamadanishiki Rice
Dassai is crafted exclusively using Yamadanishiki sake rice, often called the "king of sake rice." This particular grain is prized for its large, starchy core, which is ideal for creating the clean, complex and fragrant profiles that define premium Japanese sake. The dedication to this single, high-quality ingredient is a cornerstone of the brewery's philosophy.

Frequently Asked Questions (FAQ)
1. What does the number on a bottle of Dassai sake mean?
The number (e.g., 45, 39, 23) indicates the rice polishing ratio, or seimaibuai. It represents the percentage of the original rice grain that remains after the outer layers have been milled away. A lower number means more of the grain has been removed, which generally leads to a more refined, aromatic and delicate sake.
2. Is Dassai 23 worth the higher price?
The value of Dassai 23 is found in its exceptional craftsmanship. The process of polishing rice down to just 23% is incredibly time-consuming and requires immense technical skill, resulting in a very small yield. For those seeking a sake that exemplifies purity, subtlety and elegance for a landmark celebration or as a collector's item, many find the experience it offers to be commensurate with its price.
3. How should I store Dassai sake?
Like other premium sakes, Dassai should be stored in a cool, dark place away from direct sunlight and temperature fluctuations, such as a cellar or a dark cupboard. Once opened, it is important to keep the bottle refrigerated and sealed with its cap. For the best flavour, it is recommended to consume it within a few days of opening.
