It's a Dekang
juice. Cignot has it in both PG & VG. I just bought a lot, and for now it's my
tobacco-flavor go-to. That said, I can't say as it really resembles a Winston--certainly my memories of how they tasted in the good old (pre all-natural) days of the 1970s. For that, it would need a bit more sweetness. But I get the
sense that this is pretty much the case for all the various cigarette brand-named juices.
