I've been working with Bavarian Creme as a first try at DIY. I've noticed a strong almost antiseptic smell from the flavor, and what I think is a very strong alcohol taste when first mixed. BUT, it seems that the alcohol is vaporized first, no matter what the delivery device is. When dripping, you never lose the alcohol taste because you're always adding new juice. In the Nova, the alcohol taste goes away after 10-15 puffs. In my carto tank it takes a bit longer but once that passes it's pretty darn good juice.
My theory is that the alcohol wicks faster than the juice and burns off first. If only there was a way to wick off the alcohol while it's still in the jar... Has anyone experimented along these lines? I tried letting the bottles sit opened for 2 days and the taste was still there.
