I was never a wine drinker despite living in the Barossa valley for a few years. Over time, I slowly cultured the habit of having a glass of wine over the weekend or when I am out with friends. Still not a beer, cider or cocktail drinker but will work on that at some stage!
Melbourne has a few good wine bars to look out for and would be something to put on your agenda if you are in town for the weekend. Wine bars are great places to try out various types of wines be it red, white, sweet or fortified. I personally like a good glass of shiraz or riesling or botrylis:)
Overall, this is an excellent place to "wine" down - unpretentious, laid back, classy and very accommodating staff. I wouldn't mind heading back just to try out the other alcoholic beverages available;)
