Product description In order to get the ultimate flavor out of your favorite craft beer you need to maximize its aroma. This means the head is the key because the scent of a beer is given off as the bubbles in the head pop. In a normal poured beer once the head is gone, you lose most of the all-important aroma. With the Sonic Foamer you can actively manage your beer head throughout the entire beer.The aroma of a beer is released as the bubbles in the head pop. The Sonic Foamer allows you to start with a great head and recharge it at any time.
