If I spent more than $20 on a bottle I usually finish it the night it is opened because more than one person is usually drinking. For my “nightstand botte” I just leave it uncorked, it takes about 2-3 days to finish and it’s fine. I have a little stopper thing that I sometimes use but it doesn’t create a seal like a cork, it just uses gravity to block fruit flys and things from getting in. I’ll use it if I buy a 1.5 liter bottle because it takes me at least four days to drink those and I still end up pouring some out. I get suckered in by the price but I’m usually kicking myself afterwards. I tried a new one from costco today, a 1.5 liter $8 special from concho y toro, the xplorador, a chilean cab/merlot blend. The cheap bastard in me couldn’t resist the $4 per 750 ml average. Save your money, it sucked. It’s fun to try and find cheap wines that are good but the $7.50 threshold that menage and blackstone sit at is hard to beat, below that price point I haven’t found one that I really like. Another winner in that same range is Tin Roof, about $7.50 at costco. Costco alos had a bunch of wines on coupon, there were signs everywhere. Kewp, they had a coppola pinot for under $10, I can’t remember the exact price but it was cheap, give that a spin and see if you like it, I wish I had not gone cheapo and made that my experimental choice of the week. That’s the final tip, when you do your wine shopping each week, always pick up one “experimental.”
