So, after the most random and rambling intro ever - what I learned - and what makes sense - is that organic wine doesn't keep well overnight. A major problem though, is that getting certified to be organic costs a lot of money, but having an organic label, means your wine gets sold for less. So, many wine makers go organic - and nix the sulfites - but don't label their bottles as such. Which, may mean that you open a bottle of non-labeled organic wine one night, and find it quite awful the next.
Given this information, I suggest you follow my rule of thumb and finish your bottle of wine the night you open it - whether you're drinking alone or with a lover or friends - drink that wine down, or be ready to use it for cooking tomorrow.
