I'm looking to buy PDM Carlisle, and after everything I've heard about the reformulated version with the higher alcohol content, I'm trying to find the older, 77% version. I found a listing and am interested in buying it, but I'm unsure as to whether or not it is one of the newer or older batches. The batch code is 0500156, produced December 7, 2020. The box DOES say 77% alcohol, HOWEVER, I've heard of many instances in which the box says 77% alcohol, but the bottle says 82%. Could anyone help me out? Does anyone know the exact month/period the reformulation occurred for Carlisle?
