■ About the 'Kuradashi Vacuum Sake' Service

◆ What is the 'Kuradashi Vacuum Sake' Service?
The 'Kuradashi Vacuum Sake' service is a new sake experience that creates the “moment right after it leaves the brewery.” Sake brewed at the brewery is filled into vacuum containers on-site and distributed while maintaining freshness in a vacuum state, untouched by air. This allows the taste, as if you were at the brewery, to be served anywhere through a special low-temperature server.

◆ Features of the 'Kuradashi Vacuum Sake' Service

1. 【Always Served in Excellent Condition】
Preservation in a high-vacuum state suppresses oxidation and deterioration, maintaining the just-opened taste at the time of serving. Guests can enjoy sake in its best condition at various moments during their resort stay.

2. 【A New Self-Pouring Experience for Guests】
An all-inclusive style is introduced where guests can pour their own sake from a dedicated vacuum sake server installed in the night bar or lounge. This makes the guests' stay even more memorable.

3. 【Smart, Eco-friendly & Hygienic Operation】
The vacuum pouch supply system eliminates the need for bottle management and washing, making it hygienic and space-saving. The spout is designed to block outside air, making it ideal for hotel operations that require high hygiene standards. Being lighter and smaller than bottles, it also contributes to improved transportation efficiency and reduced environmental impact.
