enhance my travel experiences in Europe (since wine is such an integral part of their culture)
In part, I can confirm what Greg said. Most people here in Europe don't consider anymore the wine as an element of their alimentation as it was in the past centuries, even in South Europe, and the average person is not a wine geek. However, I would like to offer a different point of view. Wine is indeed an integral part of our culture. Civilization of Europe and its economy were tightly connected to wine (a lot could be said about Greece and Rome). The Dionysiac myths were the ones that really did matter in the ancient times for the common people, and left a huge mark in our culture. Literature (greek tragedy to begin with) used the wine from the beginning to convey concepts and feelings that are now commonplaces. (e.g. we still use the terms Dionysiac vs. Apollonian as a key to interpret the world). In the myth, Dionysus gets eaten and returns to life. The wine in the Holy Mass becomes the blood of Jesus. The vines and the wine are part of countless metaphoras, and can be found in architectural ornaments, paintings, poems from the beginning of Europe up to the present days. So yes, wine and enhancement of your travel experience in Europe can be related. Not so sure though that this will help you in being hired.
I found a book written by Hugh Johnson (The Story of Wine) extremely interesting and not boring at all; for sure, it's less expensive than a travel in Europe, and to me it's invaluable to put the wine in historical context. If this is of any interest for you, I'd recommend you to read it.
