So, how long does Swiss cheese last in the fridge? The answer is a long, glorious time if you treat it right. Unopened: two months. Opened: a month. Sliced: two weeks. And always, always trust your nose over the package date.
When in doubt, cut off the ugly bits and melt the rest into a fondue. That’s not just dinner; that’s a science experiment with a happy ending. Now go forth, check your cheese drawer, and remember: holes are not a flaw, they’re features. And that three-month-old Swiss? It might just be the best cheese you ever ignored into existence.
