Cannot find expiration date on a bottle of Winn-Dixie seasoning--the code is 8050R or 8050B?

Winn-Dixie seasonings typically don't have a standard expiration date printed on the bottle; instead, they often use a lot code like the one you mentioned (8050R or 8050B). You can contact Winn-Dixie customer service for assistance in interpreting the code and determining the freshness of the product. Generally, dried seasonings can maintain their flavor for several years if stored properly, but it's best to use them within 1-3 years for optimal taste.
