Wine features pretty heavily in "A Gentleman in Moscow", particularly ChΓ’teauneuf-du-Pape, but I think this is the first time I've seen Rkatziteli (Georgian, in this case) mentioned in a series or movie!
I've loved Rkatziteli since I first tasted Dr. Konstantin Frank's Finger Lakes version many years ago. Still one of my favourite wines to take to a blind tasting! π
