I have always used the occasional left over Belgian brew to wash my hair with the next morning (try it out, it leaves your hair silky and clean), but I don’t know why it never struck me to bathe in beer. Over the past 10 years, beer spas have popped up in Austria, Germany, and the Czech Republic. At these beer spas, every sense is enveloped in beer; the bubbly sticky liquid on your skin, the hops in the air, to the beer in your mug. You can also try the brewski facial: an über gooey face mask made from ground hops, malt, honey and cream cheese. These half hour bath treatments start at about $55.
