Resorttrust, Inc., in collaboration with Inter Holdings, Inc., Plathome Co., Ltd., and Mitsubishi HC Capital Inc., will begin a demonstration of the "Kuradashi Vacuum Sake" service at "Grand XIV Hatsushima Club," operated by Resorttrust.
This introduction of the "Kuradashi Vacuum Sake" service marks a first for the hotel industry.
In this demonstration, "Kuradashi Vacuum Sake" will be provided to hotel guests at the bar area.

Furthermore, storage in a high-vacuum state allows for the delicate flavors of Japanese sake to be maintained in an optimal condition. This enables guests staying at Grand XIV Hatsushima Club to select from a wide lineup of sake, always kept in peak quality, and enjoy their time at the resort even more richly.
■ About the "Kuradashi Vacuum Sake" Service
◆ What is the "Kuradashi Vacuum Sake" service?
The "Kuradashi Vacuum Sake" service is a new sake experience creation service. Sake produced at breweries is filled into vacuum containers at the source, and distributed while maintaining its freshness in a vacuum state, protected from air. This allows the "moment just after leaving the brewery" to be enjoyed in various locations through low-temperature vacuum sake servers.
◆ Features of the "Kuradashi Vacuum Sake" Service
1. [Always Served in Excellent Condition]
By storing in a high-vacuum state, oxidation and deterioration are suppressed, maintaining the taste of just-opened sake at the time of serving. Guests can enjoy Japanese sake in the best possible condition during the various scenes of their stay at the resort.
2. [A New Experience of Pouring It Yourself]
An all-inclusive style has been introduced where guests can pour for themselves from dedicated vacuum sake servers installed in the night bar or lounge. This makes guests' stays even more memorable.
3. [Smart, Eco-friendly, and Hygienic in Operation]
Because it is supplied via vacuum pouches, there is no need for bottle management or cleaning, 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 contributes to improved transportation efficiency and reduced environmental impact.
