How Long Does Canned Beer Last?
If you drink beer, chances are, you’ve wondered at some point how long canned beer actually lasts.
The good news is that canned beer is built for durability. On average, a can will stay fresh for six to eight months beyond the date printed on the bottom, but this is only as long as you store it properly in a cool, dark place.
Some craft beers, especially those with higher alcohol content or darker malts, can hold their flavor up to a year.
Canned beer is uniquely suited for shelf life because the can protects beer from light and air, which are two things that speed up spoilage.
However, canned beers don’t all age the same. Hoppy styles like IPAs lose their punch faster, sometimes tasting flat or faded after just a few months. Lagers and stouts are a bit sturdier and often keep their character up to a year if kept cold.
Pasteurization also matters. Mass-produced beers are usually pasteurized, which means they are heated to kill off microbes and this extends their shelf life.
Most craft beers, including many limited releases, are unpasteurized and should be enjoyed within three months of canning to experience the freshest flavor. Always check the “canned on” or “best by” date to guide your choice.
Refrigeration helps, too. Beer stored upright in a cool fridge will taste better for longer and keep its fizz. If you want tips on cooling your beer quickly or comparing fridge versus freezer methods, check out our guide on beer cooling.

Factors That Affect Shelf Life
Several key factors can impact how long canned beer stays fresh and tasty. Understanding these can help you enjoy the best flavor with every pour:
- Light Exposure: Even though cans protect beer better than bottles, strong sunlight or UV light can still cause chemical reactions that damage flavors. Always store cans away from direct light.
- Temperature: Heat speeds up chemical changes in beer, leading to stale or “off” flavors. For best results, keep canned beer in a cool, consistent environment. The fridge is ideal for most types of beer.
- Oxygen Exposure: While cans are sealed, small amounts of oxygen can still sneak in over time. Oxygen causes beer to oxidize, leading to flat taste and a cardboard-like aroma.
- Alcohol Content: Beers with higher alcohol by volume (ABV) tend to last longer because alcohol acts as a natural preservative. Lower ABV beers and lighter styles can lose their freshness faster.
- Ingredients: Hoppy beers, such as IPAs, are more sensitive to aging. Their bright flavors fade more quickly than malty or dark beers like stouts.
- Pasteurization: Pasteurized beers, usually mass-produced, have a longer shelf life. Most craft beers are unpasteurized and are best enjoyed sooner.
- Can Integrity: Dented, rusty, or damaged cans can compromise the seal and introduce oxygen or contaminants. Always inspect cans before storing or drinking.
- Brewer Quality: Freshness often comes down to how the beer was made and packaged. Thoughtful brewing practices, secure canning, and clear date labels all play a role. Coronado Brewing, for example, includes easy-to-read dates on every can to help drinkers track peak flavor.
By paying attention to these factors, you’ll keep your beer collection tasting its best for as long as possible.
Does Canned Beer Expire or Just Lose Flavor?
Canned beer won’t suddenly become unsafe, but its taste and aroma can change a lot.
Fresh cans deliver bold hops, crisp malt, and lively carbonation. As the months pass, those flavors start to fade. Bitterness becomes muted, and the beer may taste flat or develop a slightly sour or metallic note. Light styles and hop-forward beers are the first to lose their spark, while darker or higher-alcohol beers tend to hold up longer.
Now, the question is: can you drink old beer? Yes, in most cases. And as long as the can is sealed, not bulging, and doesn’t have a foul smell, there’s little risk. Just know the experience may not match that first, fresh pour.
If you’re unsure, compare it to a newer can of the same beer and see if you notice a difference.
How to Tell If Canned Beer Has Gone Bad
Sometimes, all it takes is a quick look or a single sip to know something’s off. If you’re wondering about signs of bad beer, there are a few things you can check before taking that first drink.
- Check the Appearance: Pour the beer into a clear glass. If you notice unusual cloudiness, chunks, or a strange color, this could be a warning sign. While some craft beers are naturally hazy, unexpected haze or floating particles often mean the beer is past its best.
- Smell Test: Bring the glass close and take a whiff. Fresh beer should smell crisp, fruity, malty, or hoppy, depending on the style. If you pick up the smell of rotten eggs, a strong metallic scent, sourness, or a skunky odor, it is best to skip that can.
- Taste: Take a cautious sip. Stale, sour, metallic, or cardboard-like flavors are common in beer that has gone bad. If it tastes “off” or nothing like the fresh version, it is better not to finish the can.
- Foam and Fizz: Watch how the beer pours. Flat beer or one with little to no foam could be a sign it is old or improperly stored. Too much fizz or a can that gushes might signal unwanted fermentation.
- Can Condition: Check the outside of the can. Bulging, leaking, or heavy rust can mean there is a problem inside. If the can is damaged, it is safer to throw it out.
If you are ever unsure, open a fresh can of the same beer and compare. Trust your senses. If it looks, smells, or tastes wrong, do not risk it.
Is It Safe to Drink Expired Canned Beer?
Let’s break down what really matters when it comes to old beer.
Is It Safe to Drink Expired Beer?
If you check the date and see that it has passed, the first thing you might worry about is your health.
The good news is that expired canned beer is not likely to make you sick. Unlike spoiled food, beer’s alcohol content and acidity help protect it from harmful bacteria. The main risk is not to your health, but to your taste buds.
Flat or sour beer can be a letdown, but it rarely causes illness.
So, is it safe to drink expired beer? Yes, as long as the can is sealed, undamaged, and free from bad smells.
Can You Drink Old Beer?
You can drink old beer, but it probably won't deliver the fresh, lively flavors you expect. Time takes away some of the beer’s sparkle and aroma.
If the can looks normal and opens with a good fizz, it is worth a taste. If the beer tastes off or you notice a strange odor, it is better to move on to a fresh can. When in doubt, compare it to a newer can of the same style and decide what suits your taste.
When to Skip the Sip
Sometimes, a can may show signs that it is best left alone. If you notice swelling, leaks, or a sharp metallic smell, do not risk it. These signs mean something has gone wrong inside the can, and it is safest to pour it out.
Beer is all about enjoyment. If you ever feel unsure, reach for a new can to get the best experience.
Does Refrigeration Make a Difference?
Temperature matters more than you might think for canned beer.
Storing beer in the fridge is one of the best ways to lock in freshness and make sure every can tastes just as the brewer intended. Cold storage slows the chemical reactions that can turn a crisp IPA or pilsner into a dull, flat drink.
This is especially true for hop-forward and lighter styles, which tend to lose their bright flavors and aromas faster when left at room temperature.
A steady, cold environment protects your beer from the damaging effects of heat, which can make flavors stale, amplify off-notes, and even lead to “skunky” aromas. While a cool pantry or basement can help if fridge space is limited, nothing beats the reliability of the fridge. If you plan to store beer for weeks or months, the fridge is the safest choice.
It is tempting to use the freezer to chill beer quickly, but this can be risky. Freezing can cause cans to burst, ruin carbonation, and leave you with a mess. For the best flavor and fizz, keep beer cold but never frozen.
Can You Still Cook with Expired Canned Beer?
Finding an old can in the fridge does not always mean it has to go to waste.
Many home cooks use expired beer in recipes, from classic beer batter to hearty stews and marinades. The heat of cooking partially removes alcohol and destroys any microbes that might be present, so using old beer in the kitchen is safe in most cases.
Before adding expired beer to your recipe, give it a quick smell and taste.
Leave it out of your recipe if it has a strong sour note, rotten egg smell, or tastes metallic. Mildly faded beer that still smells and tastes “beer-like” can add a nice depth of flavor to dishes.
Dark beers work well for braises and stews, while lighter lagers are great for batters or breads.
Cooking with beer is a creative way to avoid waste while adding richness and character to your food. Just remember to never cook with beer that smells foul or appears spoiled.

How Will You Choose Your Next Can?
Knowing how to get the most out of canned beer starts with understanding its shelf life and recognizing when it is past its prime. Most canned beers keep their fresh flavor for several months if you store them cold, upright, and away from light.
Look for clear signs of bad beer, such as strange smells, off flavors, or a cloudy appearance, and trust your senses.
You deserve every sip to be great, not just “good enough.”
If you have ever hesitated before opening an older can, you are in good company. With the right information, you can decide what stays, what goes, and what deserves a spot in your next toast.
Life is full of celebrations, quiet evenings, and backyard barbecues, each one calling for a beer that still tastes as good as the day it was brewed.
