Is it more difficult for teetotalers to develop academic contacts? I see a number of answers in this site where building contacts over a glass of beer is encouraged. Moreover the cream of academia belongs to the Western world, where beer culture is common. Unfortunately though, I am a rigid teetotaler and I do not know about the ins-and-outs of the preferences of drinking friends of mine. I confess I'd make a terrible company at a public house. But I hasten to add that in general, I am amiable and move around quite well with people within my limitations.

Does my being a teetotaler put me at a grave disadvantage when it comes to establishing intelligent academic contacts?
No. What really helps in building academic contacts is not beer, wine or any other alcohol, but the ability to generate informal discussions in relaxed settings. Fortunately, there are many ways to achieve that goal that do not require the intake of alcohol!

Even without going very far from drinking, sharing a nice lunch or dinner in an appropriate setting is one good way to establish contacts.
