I just bought the two new GL Pease and one of the cellar series and the tops are already buldging... is this a sign of mold???
Overall, mold issues with my products have occurred at a very low rate, and I haven't seen any with the new blends, and I just checked by control samples. Tin bulging is usually a byproduct of fermentation, which is actually a good thing. If you open the tins and find mold, they will be replaced.
In light of some of the other posts in this thread, Ted pretty much beat me to it, but I have a couple things to say regarding my own products.
I know that the issue with Carolina Flake was painful for everyone concerned, both the customers and the manufacturer. Though I'm not involved in C&D's affairs other than as they concern my product, I do know this situation pretty intimately, and am confident that this particular problem has been addressed and solved, and was contained within that one product. It's unfortunate that it happened, but my hat is off for the way it has been handled. In the past, it would have been a "replace as it comes up" response; the fact that C&D did a complete recall on the product is, as far as I know, unprecedented in the industry.
Prior to the merger, I worked closely with C&D to establish quality control procedures that would minimize mold issues. It's not an easy thing to do, given our combined dedication to maintaining the purest possible product consistent with mold control. But, mold spores are everywhere, and any product with sufficient moisture and something the fungi like to eat will, if not treated, is subject to occasional germination of those spores and the resultant furry infestation of full grown "adult" mold.
Years ago, we went to the industry to discuss options. Everything that we have ever tested has been a food-grade product, and safe to use in our application. I did controlled experiments to find the minimum application rates for different products at different moisture and pH levels. As a result, mold issues, at least within the GLPease catalogue, all but disappeared. (BTW the poorest performance was found in the often lauded "vinegar" solution. Vinegar in this application is absolutely NOT an effective fungistatic, evidenced by a whole mess of very fuzzy and stinky samples in my experimental batches.) We still had the occasional problem, but it was always isolated cases.
Blends with large percentages of perique, especially, are more challenging. Perique is a very wet tobacco, and quite biologically active because of its processing. Once exposed to air, it can sprout mold within weeks, or even days, depending on environmental conditions. Burleys, too, can be tricky because of the leaf's higher pH than flue-cured leaf; most fungistatics are most effective at low concentrations under a fairly narrow range of acidic pH. So, despite our efforts, some of the C&D blends were still prone to mold occasionally. R&D continued.
After the merger, C&D began further refinement of quality control procedures, and I can honestly say that the product they are making today has improved in almost every respect. Consistency of cut, moisture, and packaging is better today than it's ever been, largely thanks to Jeremy's willingness to work diligently towards improved production methods. The Carolina Flake tragedy (and it really is one, since that leaf is special) was a glitch in the system. Sure, it would have been nice if it had never happened, but it did, and was handled very professionally. And it won't happen again.
All that to say that I'm happier than ever with my relationship with C&D. We work closely together, and I'm confident in the quality of the product they produce under my label.
