Wine oxidizes. At home I use a nitrogen spray, PrivateReserve, which keeps wine fresh for up to a week. If I buy a bottle and they save it until the next day it wont taste as good. White wine lasts longer. As we get older , we are drinking less wine. I recently bough several half bottles of Grgich Hills and StagsLeap, about $25 for half bottles.
my thought was I could pack a few half bottles in my luggage and they would take up less space in checked luggage from San Francisco.may or may not do this.
appreciate all the comments.
