I have been mixing an 80% PG with 20% AG (VG mixed with some purified water so it's the same thickness as the PG). Is it possible that the AG can be diluting the flavor strength? Should I just switch to straight VG and not dilute it? I just mixed up a few small batches using the 80% PG and 20% AG ratio and all of them seem to be very weak. I know a lot of the suppliers used the 80%-20% mix in the pre-mixed juices but are they using pure VG? Would the AG weaken it that much? Thanks in advance.
