I've got some of their stuff waiting for me at home. I'll be giving it a taste as soon as I get off this trip.

I hadn't heard of them yet and might have to make my inquiries later. The one specific question I would ask is about diketones (specifically Diacetyl, acetyl propionyl, and acetion) whether added or naturally occurring. As these are known to be harmful when inhaled and still in common use for food purposes.
