When i made mine i used very strong coffee, mixed with the lye, added to oils, at trace added heaps of fresh ground coffee.
Yes, this method makes for very stinky soap at first, but cures out to a mild coffee smell. not as strong as i had hoped, but it is ok.
Does boiling it down to a syrup and adding at trace help make it more of a coffee smell? should i be adding coffee fragrance as well? or just go with the natural light scent and let the coffee grains do their thing naturally?
