Japanese brewer Suntory has designed a device that adds a head to beer poured from a bottle, according to local reports.

The Nikkei Report said today (25 June) that the brewer will offer the new device for free to restaurants that offer its The Premium Malts beer brand. The patented device works by using carbon dioxide to create the head and works automatically only when a glass with The Premium Malts beer logo is placed on the platform, the paper said.

Suntory said it will test-market the product in around 20 restaurants this month in Tokyo and Osaka and hopes to have the device installed in 1,000 restaurants by the end of the year.

This month Suntory moved to acquire a 50% stake in Austrian premium spirits producer Mozart Distillerie. The company agreed to buy the stake for an undisclosed amount in a bid to increase the presence of the Mozart brand in the global market, particularly in Korea, China, Australia and Russia.
