What's the problem?
Alcohol tends to deaden our sense of taste. So normal liquids taste blah. That is the way it goes
What to do?
Get a nice, strong-tasting tobacco liquid (e.g. small-cigar taste, like Cuban Supreme, or cigar taste, like Tuscan Reserve, both by Flavor Art).
Get a sweet-tasting liquid that goes well with tobacco flavor, like Vanilla, Caramel etc.
- - Take care that both liquids have enough nicotine. Remember chain-smoking when drinking, in your smoking days?
Mix liquids in tank of atomizer, to get a nice, not too strong-tasting sweet-small-cigar flavor. Enjoy yummy flavor.
Take both liquids with you.
As the evening (and the beer drinking) progresses, add more and more tobacco liquid and less and less sweet-tasting liquid to your tank.
You may even want to vape the strong-tasting tobacco liquid straight, as the evening progresses.
- - That will be very tasty and very fulfilling when you spend a nice evening drinking with friends.
But be careful: The rest in the tank the next morning will take your socks off
/edit:
I see that you are from Germany

In that case get Cuban Supreme, Tuscan Reserve and the Vanilla / Caramel / Torrone (very nice!) liquids from Freaky Ally. (No, I do not get paid by them, but those liquids are what I use when having a few drinks)
Advice from Germany for a German person (brands, German words for small cigar and cigar):
Cuban Supreme = Zigarillo
Tuscan Reserve = Zigarre
mixed with Caramel / Vanilla / Torrone: Cuban Supreme = Moods Sweet, Tuscan Reserve = Dannemann Sweet Zigarillos
