I am laughing right now because I just started a thread about vaping and drinking. I was talking about pairing any drinks with vaping but my thread didn't have any responses either, so I figured I would chime in here.
Have you tried BWB 555 Exotic? I just got mine and even though it has yet to mature it worked pretty decent for me with Blue Moon. It definitely has a nutty taste to it, but there is enough of a citrus undercurrent to accentuate the citrus notes of the beer.
This probably won't help you because of your taste in beers, but, find whatever subtle notes the beer has and try a single flavor juice to pair it with. I'd also be willing to bet that acidic juices would be a good start with domestics and some mexican beers. IPAs, on the other hand...don't know. It will have to be robust and maybe spicy to cut though, but hopefully someone will be of more assistance.
Good luck!!!
