Unopened packages of grits can last for a pretty long time - we're talking up to 6 months when stored in a cool, dry place. But once you've opened the package, the clock starts ticking, and you'll want to use them within a few weeks. It's kind of like when you buy a bag of coffee beans - you want to use them while they're still fresh and full of flavor.
Now, you might be wondering what happens if you leave grits out at room temperature for too long. Let's just say it's not a good idea - bacteria can start to grow, and you might end up with a batch of grits that are more sour than savory. So, be sure to refrigerate them promptly, just like you would with any other perishable food.

But here's the thing - even if grits are still technically "good" after a few days, they might not taste as great as they did when they were freshly cooked. It's like when you have a favorite restaurant - you want to go back and enjoy their food when it's freshly prepared, not when it's been sitting out for hours. So, try to use your grits within a day or two for the best flavor.
