How Long Does BBQ Sauce Last After Opening The Bottle?

While homemade barbecue sauce is quite tasty, store-bought brands also have much to offer when it comes to flavor (and even more to offer when seeking convenience). If this condiment is a staple in your kitchen, you're probably wondering just how long a precious bottle will last after it's been opened. The lifespan of bottled barbecue sauce depends on how you store it, as opened bottles can last about one month in the pantry, and up to four months when placed in the refrigerator. 

Improper storage might not rank among the biggest mistakes people make with barbecue sauce (which include using too much sauce or pairing the wrong flavor with a certain type of meat), but it's definitely worth considering. You can best prevent spoilage of the condiment by placing it in the refrigerator after opening and limiting air exposure by ensuring the lid is on tight. If you prefer to store your sauce in a pantry instead, make sure the area is not subject to sun exposure, which can accelerate spoilage. 

When it comes to food spoilage, bacteria and other microbes can develop in barbecue sauce when the condiment is exposed to air, moisture, and warm temperatures. That's why barbecue sauce and other foods last longer in the refrigerator, as the appliance is able to maintain a consistent temperature of 40 degrees Fahrenheit or below (which the USDA says is the ideal temperature for your refrigerator) to deter the growth of bacteria. It's true that some barbecue sauces contain vinegar, which can have a preserving effect on food, but even the presence of vinegar can't save your sauce from the ravages of time (and the environment). 

So, how can you tell that your sauce is no longer suitable for consumption? There are certain signs that indicate food spoilage, many of which may be glaringly obvious, fortunately. Spoiled food usually gives off an unpleasant smell that's quite distinct from the expected mouth-watering aroma due to the presence of microbes. Bad sauce may also have a questionable appearance, which can result from the growth of fuzzy mold or discoloration. Similarly, spoiled sauce can exhibit textural issues due to the formation of clumps or because of liquid separation. You can avoid these unwanted outcomes by storing the condiment correctly, as well as using it liberally when feasting on meat dishes.
