I've been trying for several months now to make a coffee soap that smells of coffee and it just doesn't seem to want to work. I started off with my base mix of oils; olive, coconut, rapeseed, and castor and added ground coffee which made a very nice exfoliating bar but didn't smell of coffee. I've since tried soaking the coffee, adding coffee butter, adding instant coffee, adding the strongest espresso I could make, replacing all of the water with coffee. Is this just a smell which isn't going to stay without some sort of artificial intervention? Or is there a trick to it that I haven't come across?
