The Electric Sheep is made with mutton tallow and the Black Cherry and Barbershop are made with beef tallow. The mutton tallow soaps some have said lather better than the beef tallow soaps but there is something about the mutton tallow that won't allow the scents to be true to the beef tallow counterparts....I got the sample pucks of the Electric Sheep, Cherry & Barbershop. All are excellent. The cherry should be avoided if hungry, since the scent is intoxicatingly intense. It seems to be the same formula as the Sheep. The Barbershop is maybe a little different formula (brown in color) but is also worth having.
