You don’t need a PhD in microbiology to figure this out. Just trust your nose. If it smells like vinegar with a side of regret, it’s probably fine. But if it smells sour in a way that makes your brain go “nope,” toss it.
Next, take a look. Fresh barbecue sauce should look like a glossy, happy puddle. If you see mold—that fuzzy green or white stuff that looks like tiny alien colonies—do not scrape it off. Throw the whole bottle away. Mold in sauce means the bacteria have set up a resort, and you don’t want to be a guest.
Texture is another tell. If your sauce has turned into a weird, watery sludge with chunky bits that aren’t supposed to be there, it’s done for. Think of it like a relationship: when it separates and gets lumpy, it’s not getting better.

Unopened sauce can hang out in the pantry for up to a year, just like a lonely houseplant you forgot to water. Once you pop that seal, the clock starts ticking.
