Have you tried Vitos? Subtler smell but IMHO better performance (more consistent lathering). Worth consideration
I'm on my first tub of Cella and it's been interesting reading through these old threads.
To date I've found it to be below both Vitos and La Saponeria Artigiana in terms of both ease of lathering and cushion. As I generally get the lather nearly there in the tub and finish on my face, today I scooped it out of the little red pot into something much bigger, which also gives a better opportunity for blooming.
As an aside, once you cut through the surface Cella from the tub is very soft, with a consistency similar to butter icing. I suspect that it is probably cured for less time than the blocks. This could also be the reason for it to go rancid occasionally due to water soaking in, as opposed to just sitting on the surface, which then alters the PH.
