Frequently Asked Questions

What's the difference between expiration and best quality dates?

Over time, Xo Sauce may experience changes in flavor and texture but remains safe to consume for an extended period. The 'best by' date indicates peak flavor quality, while the sauce can still be used beyond that date if stored properly.

How can I tell if Xo Sauce has gone bad?
