Yeah, I'd see him as a bit of a knob OP and fuck what anyone else thinks on here.
Firstly there's the boring obsessive shite from people who are into wine in a big way (you see them on Come Dine With Me boring the bloody pants off their guests - NO ONE CARES how it's pressed by the feet of the virgins from the local village and matured in olive casks containing x y and z grape varieties!!!!).
Then, in this example, there's the excessive having to overtly show you that he knew more and he was going to milk that moment - but even worse, to then force YOU to get involved as well, instructing you. Ergh, no, that would be the last date for me.
Great, I go on a date with someone knows about wine (potentially I'd be interested to learn more about wine, got no problem with that) and they say "oh DoinIt what wines do you normally drink?" and I'd say "well I like a nice crisp pinot grigio, I used to enjoy Chardonnay but went off oaked wines, I like something really light" and they'd say "ah, let's get a bottle of the [insert name of wine that probably isn't stocked in little Tesco and is more than £7 a bottle], I think you'll really like it". That would be fine. If he then wanted to 'educate' my clearly defective ass when it came to the table and we had to conduct a joint swirling sniffing and tasting session whilst he extolled the tarmac backnotes and crisp melon aroma's, I'd find a place for the cork and it might not be seen again for at least a couple of days.
Presumably he selected the wine based on his vast knowledge and aside from discreetly tasting to see if it was corked or not, there was actually no need for him to swirl and sniff and taste and then get you to do the same - when he tasted it he would have known it wasn't corked, end of story.
And I'd be quite happy to not see him again and I don't care what anyone says about it - if he's like this over a fairly unremarkable bottle of wine think what a nit-picking type he might be in other aspects of his relationships.
