Said with poetry in mind; said knowing that I often feel pretentious and know that the word can be levelled at me, if one chooses, in regards to poetry. I agree that using the more advanced, shall we say, words of a given trade can make a dabbler or novice feel alienated or looked down upon. I am aware that the words used in wine tasting have specific meanings and usages. I looked at a wine chart that delineated these once. It was astounding. Unfortunately, it was about as edifying as you or the theoretical narrator of your post would find a chart of poetic terms.*Keeping in mind that pretention is often in the eye of the beholder, and I'm not pretending that this use is an exception to that.
My point was to use something that I know you are passionate about and love as an example of how an in depth understanding has to come with more in depth language and descriptors. You know the old adage that eskimo's have hundreds of words for "snow." When I look at snow I see "snow." When they look at snow they can see a vast array of various textures, colors and conditions. We're looking at the same snow. You're tasting all those descriptors you mentioned, you've just not given them proper names and compartments in that big brain of yours. Tell ya what, some day you, me and kleinbl00 are having a wine tasting :)
TNG makes a good point. I think I've mentioned this before, but the only way to learn about wine is to drink comparatively. Meaning, drink two/three wines at the exact same time - not one bottle and then the next. If I were to put two glasses in front of you there's no doubt that you could tell me which has deeper colors, which smells more like bruised fruit, and which one has a longer finish. When you're just drinking one, all that goes out the window.
