Have you purchased a bottle of A1 sauce but are not sure how long you can expect to use it for? Or alternatively, you’ve had a bottle for a while and wondering whether it is still safe to consume? Either way, this is what you need to know about the shelf life of this popular steak sauce.
So, how long does a1 sauce last? A1 sauce will generally last for between 6 months-2 years once opened if stored properly and appropriately. Refrigeration typically extends the shelf-life further. Although when unopened, it can last for 3 years (if kept out of sunlight and kept in a cool place). Best-before dates on the label can give you a baseline to work from.
For the most part, A1 sauce lasts a long time.
Even once it has been opened.
And that has a lot to do with the ingredients. But more on that latter.
What you need to know is that you should get a lot of use out of this sauce, and preserving it needn’t be too difficult.
As we shall now explore in the following sections.
Does A1 Sauce Need To Be Refrigerated?
A1 sauce does not have to be refrigerated, even after opening, although it is recommended that you do so. Generally, this sauce lasts longer and will remain fresher if you are to do so.
That’s because the cooler environment will help to prevent bacteria from forming.
That being said you do not necessarily have to refrigerate it – even if it does come recommended.
But you will need to keep it in a cool, dry place away from any direct sunlight and any potential heat sources.
And by refrigerating, you can expect up to two years of use – assuming you put the lid on properly and ensure it does not get contaminated with other foods.
Does A1 Sauce Expire?
A1 sauce does not expire. Instead, it carries a ‘best before‘ date which is the manufacturer’s estimate of how long the sauce will remain at peak quality. This is not a safety date.
Ultimately when, and if, this sauce ‘expires’ is going to come down to personal preference.
And it’s going to come down to how you like your A1 sauce and if you notice any degradation.
Unless there are signs of spoilage of course, but more on that in the next section.
Of course, storage of the sauce can help keep that quality longer.
And, if you are yet to open the bottle and are keeping it in a dark, dry, and cool place – well, this sauce will last you a long time!
How Do You Know If A1 Sauce Is Bad?
Signs that A1 sauce has gone bad include changes to the color, texture, and flavor.
These changes will typically occur in two scenarios:
- Improper storage,
- After the “best by date” or if the sauce has been owned for a long time.
Nevertheless, it’s important to monitor changes over time and check before consumption.
You’ll always want to start with a visual check, followed by smelling the sauce.
If you do notice a bad odor, or changes to the sauce visually – throw it away.
But if the sauce passes those two tests then move on to the taste test.
But do only consume a little bit, on its own, at first.
That way you can check and notice any degradation.
If you then notice a funky taste, again be sure to discard it.
If in doubt, throw it out.
For the most part, these changes will only occur if the bottle has been opened, and the sauce has been exposed to air and moisture for too long.
Such as when the lid has not been put back on properly, or if left off for some time.
Alternatively, the sauce can go off if it has been contaminated – whether other foods get into the bottle and begin to break down.
What Happens If You Eat Expired A1 Sauce?
For the most part, assuming there is no mold, you should be perfectly okay to consume expired A1 sauce (or sauce that has gone beyond the best before date).
Remember, this sauce doesn’t really expire – the date on the bottle is for best quality only.
So, if you eat A1 sauce beyond this date you may just be disappointed.
You shouldn’t get sick, at least.
And while for the most part, it is perfectly safe, there are no guarantees.
Especially if there are in fact signs of spoilage or cross-contamination.
A1 sauce generally lasts a long time.
You’re looking at between 1-3 years, on average.
Even after it has been opened!
We have a high vinegar concentration in the sauce to thank for that.
And besides, vinegar is a known bacteria killer, at least for some of the foodborne strains such as Salmonella and E. Coli.
So, rest assured you should be more than okay to consume the sauce beyond the best before date.
It may not taste as good, mind you.
Can You Freeze A1 Sauce
You can freeze A1 sauce to preserve it for longer, but it is important that you transfer it to a freezer-safe and airtight container before you do so – otherwise, the bottle will shatter and it can spoil. You will need to fully defrost before consuming.
