People outside the wine community tend to look at wine lovers, especially wine lovers who like to talk about wine, as wine snobs. I suppose many years ago there was some truth to the aspersion. As wine was growing in popularity in the late 20th Century it was an aspirational beverage and thus sometimes consumed by people who boasted about vacation trips to Europe and wanted to be seen as having good taste.
But for several reasons that image of wine as a playground for the wealthy or wannabe wealthy no longer applies.
— In affluent countries wine is consumed by people from almost all social classes, and certainly the middle classes.
–Due to advances in technology and global distribution networks, wine is no longer identified exclusively with European taste but is produced and available throughout the world.
— Wine knowledge is widely available and can be acquired by almost anyone for a relatively modest expense.
–There is no evidence that wine tasting ability requires remarkable sensory abilities or cognitive skills.
–Wine expertise requires only dedication which can be sustained by most people with access to the necessities of life.
–Wine appreciation involves knowledge and skills that can be communicated to anyone with an interest in them, and judgments about wine are widely shared.
This is not to say that there are no barriers to someone with an interest in wine. The cost is not negligible and at least average sensory abilities and cognitive skills are helpful. But that is true of any human practice. Wine has become thoroughly democratized. There are of course snobs but there is nothing about wine that makes wine lovers particularly susceptible to snobbery.
