beginning wine lover/ longtime drinker here and I saw an ad that said something to the effect of "2005 sauvignon blancs are still good for the fall" and I didn't even know they might go bad that soon. So I'm wondering about the longevity of a 2005 grenache blanc i bought from epiphany, and also how long other 2005 whites last - gewurtzraminer, sauv blanc etc?
I recognize that there will always be estimations and that this is a general question, but all I'm hoping for are general answers are perhaps ways to estimate how long something like this will last.
also, I still have a couple bottles of some 2005 rosays i was drinking and was wondering if they too might "go bad" of off before december.
Thank you! I'm a novice!
