We start with wine, a drink whose enthusiasts, knowledgable fans, aficionados, connoisseurs, and the like are legion, so not surprisingly we have a name for them, with alternative spellings: oenophiles / enophiles. Beer is equally appreciated and enjoyed by many, but there are relatively few beer connoisseurs. But, even if there are few of them, they presumably have a name — maybe an obscure one, but a name nevertheless. What’s the solution to this proportional equation?
wine : oenophile :: beer : X
It turns out that there are (at least) two solutions for X, one Latin-based (like vinophile for wine, which is so rare that it doesn’t make it even into the OED), the other Greek-based like oenophile (Greek to accord with the Greek second element –phile). You’re unlikely to have come across either of them, but the second, Greek-based one, is especially delicious for me, because it’s a Z -word (like Zwicky), and because it came to me through a Facebook friend, Martyn Cornell.
