Do you have any rules/guidance on figuring out the drinking windows for half bottles of Bordeaux as compared to 750's? I am specifically interested in cheval blanc, leoville poyferre, latour, angelus, cos, LMHB, HB, Mouton, Lafite, SHL. Am planning on buying half bottles for drinking with dinner and my wife doesn't really drink much, maybe half a glass. I usually drink a glass. Hence the half bottle idea. The full bottles I am accumulating will probably only be consumed when we go out to dinner with other people or have others to our home, both of which are not that often. I have come to realize that full bottles are probably better to collect but, at this point I might not live to drink them and as I have mentioned, full bottles are just too much wine for dinner and the next day the wine, for the most part has gone bad. I have gone to white burgundy/Chablis/sauternes as my daily drinkers so far because they keep very well in the fridge, even up to two weeks, depending on the quality of the wine. But I want to experience Bordeaux as a daily drinker and so am looking to a half bottle subcollection as a solution.
