I now have four kinds of beer soaps I've been making this past week. From left to right: Corona, Labatt Blue, Rickards Red and Guinness. I wanted to experiment with different types of beer from light to dark. Labatt Blue was my middle of the road beer soap. Strange thing with Labatt Blue: I boiled the alcohol off the beer before adding my lye to the liquid. All the other beers reacted the same way to lye as it does with water. When I added it to the Labatt Blue, it was a stronger reaction. It bubbled up, but not over and there was a brownish/yellow color in the foam. I'm thinking Labatt adds something to their beer that reacts funny with the lye. It has me thinking twice about drinking it.
