I now have a couple of beer soaps on the Briallen site.
This first one is made with Welsh Stout from the North Wales Brewery, a micro-brewery near Abergele. I added a small amount of raw cocoa butter to get the darker colour.
The one below is from the Purple Moose Brewery in Porthmadog - it's a draught beer (so no bottle in the pic) and the Myrtle Stout is brewed just once or twice a year - mainly for Halloween.
Both breweries have said I can use their logos on my labels and the North Wales Brewery is going to sell my soaps made with their beer from their stands at various shows and festivals.
