■ About the "Kuradashi Vacuum Sake" Service

◆ What is the "Kuradashi Vacuum Sake" Service?

The "Kuradashi Vacuum Sake" service is a new sake experience that allows sake brewed at a sake brewery to be filled into vacuum containers at the brewery and distributed while maintaining freshness in a vacuum state, untouched by air. This enables the "moment just after it leaves the brewery," which can be tasted at the brewery, to be offered in various locations through a low-temperature server for vacuum sake.

◆ Features of the "Kuradashi Vacuum Sake" Service

1. Always Served in Optimal Condition

By storing in a high-vacuum state, oxidation and deterioration are suppressed, maintaining the taste as if freshly opened even when served. Guests can always enjoy sake in its best condition in various scenes during their resort stay.

2. A New Experience: Guests Pour Their Own Sake

An all-inclusive style is introduced where guests can pour their own sake from dedicated vacuum sake servers installed in night bars and lounges. This makes guests' stays even more memorable.

3. Smart, Eco-friendly & Hygienic in Operation

Since sake is supplied in vacuum pouches, bottle management and washing are unnecessary, making it hygienic and space-saving.

The spout is designed to block outside air, making it ideal for hotel operations where high hygiene standards are required. Being lighter and smaller than bottles, it also contributes to improved transportation efficiency and reduced environmental impact.
