TIL that putting a spoon in an open wine bottle doesn't keep it fresh
I had a half bottle of red left over from dinner last Friday, and I stuck a metal spoon in the neck like my grandma always did. Woke up Saturday morning, took a sip, and it tasted like vinegar. Apparently the spoon trick is a total myth, the cold metal does nothing to stop oxidation. Has anyone else fallen for this old wives' tale or is there actually a cheap way to keep wine good for a few days?
