It was great, sadly it's all gone now! Joel and Nick (B&B) made a batch or two some time ago in the name of research into top quality soap ingredients. I was lucky enough to receive a sample puck from batch 1 and it was truly superb, about the best soap I ever tried. I didn't get to try batch 2 but i hear it was even better.
Sadly they have no plans to mass produce and sell it, I believe as the cost of ingredients is too much and the end product would be too expensive. It's a shame, believe me! :(
