Frequently Asked Questions
Everything you need to know about the South's favorite mayonnaise.
What makes Duke's Mayonnaise different from other brands?
Duke's is the only major mayonnaise brand that contains no sugar. We use a high ratio of egg yolks and a unique blend of vinegars to create our signature tangy, 'home-made' flavor profile.
How should I store my Duke's Mayonnaise once it arrives?
Unopened jars can be stored in a cool, dry pantry. Once the seal is broken, Duke's must be refrigerated to maintain its quality and freshness.
Does Duke's Mayonnaise contain any common allergens?
Duke's Mayonnaise contains eggs. However, it is naturally gluten-free and contains no dairy or soy protein, making it suitable for many dietary restrictions.
What is your shipping policy for glass jars?
We take great care in packaging our products using protective materials to prevent breakage. We offer standard and expedited shipping across the United States, with tracking provided for every order.
Can I return food products if I change my mind?
Due to food safety regulations, we cannot accept returns on opened or unopened food items. However, if your order arrives damaged or incorrect, please contact our support team within 14 days for a replacement or refund.
What is the shelf life of a jar of Duke's?
Each jar is stamped with a 'Best If Used By' date. For the best flavor and texture, we recommend consuming the product before this date, though it typically remains safe for a short period after if stored correctly.
