<<Disclaimer: Verify this information before applying it to your situation.>> In response to a message I sent asking follow up questions about their GF status, I received a generous packet of information from the Tabasco company. I have to commend them for the care and thoroughness of their response. According to the material they provided, which included copies of lab reports and copies of signed letters from their suppliers, their products have mostly vinegar content. The vinegar is made from a distilled alcohol. Although the alcohol comes from grain sources (possibly including wheat) originally, the company represents that distillation removes all the protein and confirms this by testing -- no gluten can be detected with normal tests. They admit that these tests have a detection limit -- a very, very, very low one, but still a limit. They suggest that anyone who has a concern about ultra-minute amounts that could conceivably exist below that limit consult their doctor for advice. I personally avoid all grain source products altogether. However, those of a more moderate bent may wish to consider the info they provide. The care and detail they put into their response is wonderful and, IMHO, deserves to be rewarded. I wish we could get other companies to put one tenth of the effort and care into their consideration of our concerns that Tabasco obviously has!!! If I don't buy the stuff for myself, I will certainly buy it as gifts for friends!
