Wine should have a purpose, and that purpose demands the opening of the bottle.
Unless a wine is in some respect faulty, it will always have a purpose; wine can be crap, it can be contemplative or it can be conversational (thanks Juel) but given the right circumstance it is always fit for purpose – even if the purpose you have in mind is cooking – just to say I’ve done it, I did once add a little 1996 Lafite to a sauce reduction.
If it’s not fun, there is no point 😉
Now for some swiss wine – where are my skis!!!
