Most of us were drinking what was already opened, or even the beer in the cooler.. but one guy... one guy, had to talk about every bottle. Go through a glorious ceremony for each. Find the perfect glasses, and people to talk to about it. It got pretty annoying, to the point the wine loving host himself was like, great to meet you, but why don't you and I get together some other time, let's focus on (couple's name) instead.
There you have two kinds of wine fans, one I like, one I couldn't stand being around. My mother is a third kind, the one obsessed with finding the highest quality to cost ratio she can. I'm not sure how I feel about her :)
Don't be the dude who grabs a bottle of my good scotch and pours it on ice in a rocks glass. The bottle of Jameson was right next door for a reason.
I don't find any of this pretentious, and more general interesting conversation.
You mean, "terroir".
For example, there's a group of wine selections that I've found to be pretty tasty (and often pretty affordable, with many in the $15-$25 range). I went into a busy wine store in an affluent neighborhood and asked the people in the wine department if they had any wines of that select, and they looked at me as if I was from the moon. They told me that's not the way wine is organized - they wanted me to give them a price point and tell them if it's red or white. That's how a lot of people approach wine: "I want to spend N dollars on a X color wine."
(I went to a smaller wine shop near a college, and they knew just who I was talking about)
People have said it's like talking about Vim vs Emacs, and it is somewhat, but it's like hearing people who have never used Vim or Emacs talk about Vim vs Emacs. Have you ever come across those conversations? Everyone is just repeating things they read and saying what they believe the common consensus is, and no one is thinking for themselves.
Do these people actually exist or have you just heard about them on TV and over-match any time you hear some one talk about wine for more than 30 seconds?
