i recently purchased a couple 15 gallon containers that were advertised as "food grade." however, I cannot confirm the food-grade nature of the containers from any information on the containers themselves (that, and they smelled kinda funky/plasticky upon delivery). I fermented a couple batches in them without any off-flavors, but for future use I was hoping to line them with disposable food-grade liners for some peace of mind (their shape fits my fermentation fridge perfectly, so i would like to keep them in service).
I checked this thread as well as this one and although the existence of such 15 gal liners is mentioned, a specific source is not. the only source i could find online is here in canada, and these might work (but are costly), so i was hoping I was missing something obvious and someone knew of a fast and easy source for these. thanks!
