Ultra fine foam is a lid that protects beer. It traps carbon dioxide gas & prevents beer from deteriorating by exposing to air. The fine foam is also made of isohumulone, a bitter conponent of hops, and by trapping bitterness in the foam, gives beer a mellow taste. The pleasant sound when pouring beer will further enhance your desire to drink beer.
