It really depends on the wine as said earlier. I know pretty much nothing about wine and I could tell you the difference between a couple white wines because some are noticeably sweet (moscato, riesling) compared to others (sauvignon blanc, pinot grigio). I could id the first category vs the second, while somebody into wine presumably would have more depth.
