How to fix gross, smelly wine with science

Look, sometimes wine just isn’t tasty. But if the thing that has you wrinkling your nose is an odour like rotten eggs or burnt rubber, there might be a quick, cheap fix. Like, really cheap.

All it takes is a single penny. Or a silver spoon, if you’ve got something to prove.

Dropping a penny into wine that tastes gross sounds like a bad idea. After all, throwing good money after bad is generally a dangerous game. But when the bad money is skunky wine and the good money is a single, well-washed penny, I’m all for it.

Here’s why it works: These sulfur-y smells usually come from a chemical process called reduction. Reduction can produce stinky sulfur molecules called thiols. But luckily, copper reacts with these molecules to create copper sulfide crystals — which are blessedly odourless.
