Have you ever stared into a mug of lager and thought, "hey, this stuff would be a great way to clean my body!" Well you, and at least one other dude, had the same idea!
Beer Soap is soapbar made using 100% beer as the liquid portion, with the rest made with a special recipe of olive oil, sunflower oil, unrefined shea and cocoa butters, and more. Available in many types of beer-specific varieties, these bars don't smell like beer, but instead offer just a hint of hoppy aroma as an additive to more complex aromas. Kind of a shame -- I was looking forward to using the excuse "I've been bathing" next time I come home reeking of booze.
