A craft beer producer in central Japan is hoping that its U-shaped “wobbly” glass will encourage people to drink water along with their beer, in a bid to prevent excessive alcohol consumption and dehydration.
The “Wobbly Beer Glass by Yona Yona Ale”, produced by Yoho Brewing based in Nagano prefecture, has been on sale since August amid growing awareness of the need for responsible drinking. The idea is that the glass, divided into two sections, will tilt if a balance between beer and water is not maintained.
Japan’s Ministry of Health, Labour and Welfare, in guidelines released in 2024, encourages people to alternate between drinking alcoholic beverages and water to slow intoxication.
Kyoko Kitano, the employee in charge of developing the glass, was inspired by conversations with a colleague about forgetting to sip water while drinking with friends.
