For just $19.97 Whether it’s served in a pint glass or an oversized mug, a beer just isn’t a beer without the proper beer head! This frothy foam layer does more than just apply a temporary mustache; it’s a whipped up infusion of wort protein, carbohydrates, polyphenol and isohumulone, the chemicals responsible for the bitterness in hops. That’s why beer is most refreshing and delicious with some foam on top — so what do you do when it’s all gone? No need to worry! We've got the Beer Foaming Mug that re-foams your beer with the simple click of a button. Now, you can enjoy a fresh foamy head from the first refreshing sip to the last delicious drop. Cheers! The Beer Foaming Mug would make the perfect gift for the Beer Connoisseur in your life!
