I used Blue Moon beer to make this batch. The beer has a citrus element to it...so to enhance it a bit more, I added litsea cubeba essential oil (a lemony scent)...although I didn't use the full amount of essential oil required for this recipe because I didn't want it to overpower the hops smell. I'll see how much of the lemon scent is left after the soap is cured. It does smell great though!
