Last weekend I made my first batch of beer soap. I put a 12 oz bottle of Redhook Autumn Ale in a water bottle and left it in the fridge for a week to get it flat. Then I put it on the stove and boiled it down to just 1.5 ounces of beer syrup and added it to the batch at trace. It seemed like a tiny amount to add to a 70 oz. (about 2 kg) batch but it was concentrated. The batch heaved little bit in the first 24 hours, I presume due to the sugars in the beer syrup.
Those of you who boil your beer down, as I did, do you boil it down to a syrup? If so, how much beer syrup do you add per pound of oils?
