I will try to call down there (to the store) and see if I can ask my old boss in Bulk about this stuff...and I will report back. I do remember Frontier as being pretty reputable, to the extent that when there was a cayenne shortage they did not stock it until it was up to their quality standards, which I remember because we got so many rude customers about it. There is nowhere like a health-food store for really rude customers. All those health freaks. ;)
