Save spoiled wine the easy way–and it will only you cost one cent! If your wine has gone bad (and you’ll know it has, if it smells like sulphur), find a clean copper penny and drop it in the glass. Stir gently, then remove the penny.
And now, to impress your friends, here’s the science behind this hack, from the American Chemical Society: “The copper in the penny interacts with thiols, or stinky sulfur compounds, in your glass of wine. The wine has thiols as a result of a common part of the grape-fermentation process known as reduction, in which fermenting grape-juice sugars are kept from interacting with oxygen.”
We knew that.
