Beer spa!
I'm presuming spa days are fun. As a guy, I've never done one. Mashable, however, recently reported on a Sisters, Oregon spa involving some of beer's key ingredients in their treatments.
Live many spas across this nation, Hop in the Spa offers many standard spa treatments: Swedish massage, hot stones, various ancient healing treatments. They are also offering treatments such as "microbrew soaks" and utilizing ingredients like barley, herbs, and hops and "hop-infused oils". The idea is that microbrews are made from materials that include vitamins and minerals like iron, selenium, magnesium, B1, B3, and more, and that these vitamins and minerals "will help with insomnia, anxiety, stress and help calm the nervous system down." Per an interview with Mashable, Hop in the Spa plans a future beer garden so customers can relax with a pint after treatments, and to sell branded products via their website.
You check out the "Services" tab in the link above for a full rundown of their beer-related and non beer-related services.
