■ About the "Kura-Dashi Vacuum Sake" Service

◆ What is the "Kura-Dashi Vacuum Sake" Service?

The "Kura-Dashi Vacuum Sake" service fills sake brewed at a brewery directly into vacuum containers at the source, distributing it in a vacuum state with no air contact to preserve freshness. Through a dedicated low-temperature vacuum sake server, it delivers the "moment right out of the brewery" experience — the taste as it was at the cellar door — in a variety of locations.

◆ Key Features

1. [Always Served in Optimal Condition]
Storage under high vacuum suppresses oxidation and degradation, maintaining the just-opened flavor at the time of serving. Guests can enjoy sake at its best in every moment of their resort stay.

2. [A New Self-Pour Experience]
An all-inclusive style lets guests pour their own sake directly from the dedicated vacuum sake servers installed at the night bar and lounge, making their stay even more memorable.

3. [Smart, Eco-Friendly & Hygienic Operations]
The vacuum pouch supply system eliminates the need to manage or wash bottles, making it hygienic and space-efficient. The spout is designed to block outside air, making it ideal for hotel operations that demand high sanitary standards. Lighter and more compact than bottles, it also contributes to improved shipping efficiency and reduced environmental impact.
