Why does brie taste bad?
Why does brie taste bad? Brie cheese tastes sour when it is too old. It's a good idea to buy brie cheese from a store where you know the cheese has been stored properly. If you want to eat brie cheese, buy it fresh. What happens if you eat spoiled brie? So while after two or three weeks past the date on the label it might still be perfectly safe to eat, the taste likely won't be anywhere near acceptable. If the taste isn't good enough, cut your losses and throw it out. Don't expect old brie to go sour...
