any fragrance the coffee has will be eaten by the lye monster. If you want a coffee fragrances soap I would use a coffee FO. Adding coffee to soap helps give it a nice brown colour and adding grounds is great for a scrubby soap. But please make sure it is a really fine ground as it can be very scratchy if its not a fine ground. Ask me how I know this....
And when you add the lye to coffee you'll be glad that the smell doesn't stay! It will smell terrible to start with
If you weren't already convinced I like Espresso from BrambleBerry too. I just unearthed a whole batch I had boxed away probably a good year, or two ago, thinking the bar was too soft and it still smells nice.
It had to be the recipe. I have used coffee to color soap a long time, as well as using ground coffee for an exfoliant, and I have never had soft soap from any of it.
Was it the recipe that made it soft or adding the ground coffee or liquid coffee?
