Beer is favored by many people for its unique wheat aroma and slightly bitter taste, especially the foam floating on it. It tastes delicate, smooth and fragrant and is irresistible. However, if the beer is left for a long time, the foam will disappear and it will have no taste at all. Sonic Foamer ultrasonic beer foamer can restore foam to expired beer. Just place the wine glass on the base, press the start button and wait for a while, the beer will be filled with foam again. The longer the time, the more foam will become. People who like beer cannot miss it.
