I tried the winter grape from totally twisted texas and it's pretty tasty imo.
It's VG though, not PG. It's not a standard grape though, it has a touch of menthol(?) icy/cool with the grape.The grape part was kind of concord jelly tasting to me.
Was pretty yummy and I don't normally go for anything with menthol/icy. They have reasonable priced samplers too so you don't have to spend a fortune to see if you like it or not. ttteliquids.com
