Opened sauerkraut lives in your fridge for about 4 to 6 months. Yes, months. That’s longer than your leftover pizza guilt.
Unopened? It’s practically immortal. Check the best by date, but you’ll often find it’s good for one to two years in the pantry. Crazy, right?
Why does it last so long? Because sauerkraut is already fermented. It’s a living, breathing pickle. It’s been preserved by lactic acid bacteria since day one.
