hahahhaha :) it might be a bit too hot for a bath, but it might feel really nice, not sure - I prefer my coffee in my mouth :) Actually, coffee is a little bit sticky, come to think of it, because of the oils in it, maybe this kind of bath would merit another after, to wash off the coffee.
Maybe just coffee infused or cocoa infused hand milled bar soap, instead. :-)
But yeah !! It would smell good for certain. 😂
