    Have you ever found yourself staring at a forgotten bottle of beer in the back of your fridge, wondering if it's still good to drink? Well, fear not! Today we're going to explore the age-old question of how long beer is good for after it's brewed. 

    We'll cover everything from storage tips to signs of spoilage so that you can enjoy your favourite brew confidently. So, let's crack open a cold one and get started! 

    How Long Can Beer Be Stored?

    Beer's storage life is affected by the bottle and the environment. Beer in bottles can be kept in the fridge for up to six months. However, beer in bottles has a three-month shelf life, and in a heated atmosphere, it cannot go well. Crowlers and growlers, on the other hand, go stale more quickly.

    After Being Opened, How Long Does Beer Last?

    Beer won't keep well once it's been opened and exposed to light and oxygen. In addition, exposure to air and loss of carbonation alter beer's flavour over time. Beer should be resealed with an airtight cap and stopper as soon as possible after opening to prevent oxidation and carbonation loss.

    Whether you're a beer lover or a spirit enthusiast, we've got something special waiting for you at Tar Barrel – guaranteed to tantalize your taste buds. 

    What Will Happen If We Drink Beer That's Beyond Its Expiration Date?

    There will be little change other than a possible permanent distaste for beer. In its fresh state, beer has the ideal sourness, acidity, and carbonation balance.

    Beer stored for longer than its best-before date can go stale. Towards the end, all the foam will be gone, and the sour taste will predominate. You probably wouldn't want to ingest anything so disgusting.

    So, can you drink expired beer? To put it briefly, yeah. The lengthier version of the answer is that you won't enjoy it. If you're wondering, "Does old beer make you sick?" you may rest assured that it probably won't, but it might give you a stomachache. 

    Beer that has been open for too long may have a flat, skunky, or unpleasant flavour because of its age.

    How Long Does Beer Last

    Drinking most beers is recommended the day they're released from the brewery. Brewers are experts in their field, and they sell beer that tastes exactly how they want it to. 

    Craft beers that have just been brewed are bursting with life and flavour. However, this rule has several exceptions, as most things involve beer.

    Stronger storage life can be expected from stronger beers like imperial stouts and barley wines. Several of these beers improve with age, developing deeper flavours. Even sour or wild beers improve with age, revealing new and exciting flavours. The addition of yeast and bacteria causes these beers to change over time.

    Some flavour components in beer change and develop as the beer ages. Flavour components in the malt, yeast, and hops all interact with oxygen to bring out specific nuances in the beer's profile. 

    As time, the flavour fades because other components degrade. Usually, the bitter taste fades after some time has passed. On the other hand, a beer's ability to absorb sweet, sherry-like flavours improve over time, as demonstrated below:

    Bottled Beer

    Beer in bottles can be stored for up to six months in a dark, cool place like a refrigerator. However, bottle beer can become bad within three months if kept at room temperature. Avoiding skunky off-flavours in beer is as simple as keeping bottles out of the light.

    Intense exposure to light can severely spoil beer. Hop compounds are photosensitive. Therefore, they will be "light struck" if exposed to light. The skunky taste comes from this.

    Beer in Cans

    The best protection against oxygen but also light can be provided by it. Cans are made with as little air space as possible between the lid and the beer inside to prolong the beer's freshness. However, beyond geometry, it can block out light entirely. 

    Beer in cans should be drunk within three months when stored at room temperature and six months if refrigerated.

    Beer Kegged

    Keeping beer in kegs at a cool temperature is essential. Never be shocked by a bad beer at a tavern that keeps its kegs at a warm temperature.

    In most cases, the flavour of kegs that have not been pasteurised deteriorates after 45-60 days. In contrast, the shelf life of pasteurised kegs is around three to four months.

    Once a commercial keg is tapped and served with a party pump, the beer only has a shelf life of 12 to 24 hours. After that, the beer quickly goes flat and stales when air is forced in to force it out.

    Crowlers And Growlers

    Several taverns, brewpubs, and brewers provide growler and crowler refills from the taps, allowing you to take a fresh pint home whenever you choose. Still, this beer is best enjoyed as soon as possible. 

    Beer can easily oxidise while being filled. Hence it's important to use a specialised filling machine. The beer's taste consequently decreases rapidly. Consumption of the contents of a growler or crowler is recommended no later than 36 hours after filling.

    How To Maintain Beer's Quality Over An Extended Period

    If you need help with how to store your beer, it is always best to ask the brewery for guidance. But that approach might only work in certain circumstances. For example, to keep beer fresh or extend its shelf life, often only three ingredients are required:

    Proper Storage

    The type of beer and its packaging (bottle, can, keg, or growler) are just two variables that affect how long you can keep beer on hand. 

    The universally desired environment is dark and cool, with "cool" defined as a temperature range between a typical room and freezing.

    Upright Position

    Large containers like kegs should be stored separately from perishable items to prevent contamination. The best way to keep beer is in good containers rather than on their sides. Beer should be stored upright with as little movement as possible, even when ageing in a basement.


    The beer loses its freshness rapidly when exposed to light and heat. Thus, storing it in the fridge is always recommended. The ageing process begins when the product is packaged and can be slowed down by exposing it to cold temperatures. Beer is protected from UV radiation and heat in the dark. Beer kept at room temperature, even under fluorescent lights, will lose quality.

    When storing a large quantity of beer for some time longer than a few days but shorter than a few weeks or months, the refrigerator, rather than the freezer, is the preferred method for preserving the beer's flavour. If you don't have room in the fridge, the next best thing is a cool, dark place where the beer won't be disturbed.

    Remember that beer is not wine, so you can't just put it in the cellar and expect the flavour to improve over time if you keep it there for a long time if you're looking for beers suitable for ageing. Although ageing slightly improves the beer's flavour, letting it rest for too long causes it to spoil.

    How Does Beer Go Bad?

    Beer can be affected by numerous variables. Alcoholic beer is the most consumed type of alcoholic drink, but it spoils quickly if left alone.

    Keeping an eye on your beer can help it last longer. While brewers pay close attention to quality control, there are still steps you can do to maximise your beer's enjoyment. There are three main foes you want to avoid when drinking beer. They consist of the sun, air, and any germs present. This is how much they despise beer.


    Beer is just as susceptible to the damaging effects of the ultraviolet sun as skin is.

    Keep your beer out of direct sunlight for as long as possible. If you expose hops to UV light, a molecule in the plant reacts with the light.

    Hops are responsible for the unique flavour profile of each beer. Thus, the UV rays strike at the very core of your existence. Unfortunately, things are becoming even worse! The beer will continue to react this way until it smells like skunk spray. For that very reason, indeed, black bottles have become standard.


    As a result of oxidation, we age. Beer responds to oxygen exposure in the same manner as any other substance when exposed to air. Changes in beer flavour are produced due to the breakdown of chemical components.

    The beer typically develops a buttery taste and aroma. This is because many flavours are produced when oxygen reacts with other elements. Occasionally, it can even take on a cardboard flavour. It's more of a problem with bottled beer than canned beer. Beer in the latter rarely touches air because of the superior seal.


    Everything deteriorates with time due to microscopic organisms. Bacteria can't survive in alcohol. Thus, the process takes a while. The prevalence of microorganisms is likewise reduced in commercial beer. Improved equipment has helped brewers reduce the likelihood of contamination.

    Keeping your life nectar in the fridge is another fantastic way to prevent harmful bacteria from growing in it. Cold weather similarly affects the yeast used to ferment ales, slowing down their reproductive cycle.


    This text tackles the age-old subject of how long beer is good for once it's made. You'll learn all you need to know about beer, from how long it can be stored to how to spot spoiled bottles, as well as whether or not the packaging affects the beer's taste. 

    Beer can be kept in the fridge for up to six months, but in a hot climate, it cannot go well. Alternatively, crowlers and growlers lose their freshness more rapidly. 

    Beer in a can has additional benefits, including portability and security against oxidation and carbonation loss. Maintenance of bottle packaging is problematic, and recycling of bottles does not occur as frequently as we would want.

    Beer can develop a flat, skunky, or disagreeable flavour if it's been stored past its best-before date, which is one of the main points of this article. Most beers taste best when consumed on the day they were created, and freshly brewed craft brews have an intense flavour and aroma. 

    Beer in bottles can be stored for up to six months in a dark, cool area like a refrigerator, but bottle beer can become bad within three months if left at ambient temperature. 

    The best protection from oxygen and light is provided by cans, which should be drunk within three months when stored at room temperature and six months if refrigerated. 

    Maintaining beer in kegs at a low temperature is vital, as the flavour of kegs that have not been pasteurised deteriorates after 45-60 days.

    The ideal conditions for consuming a growler or growler are a dark, cold place, with "cool" being defined as a temperature range between room temperature and freezing. Appropriate storage of large containers like kegs should be stored apart from perishable objects. 

    Beer tastes best when stored in the refrigerator, where it is shielded from light and temperature extremes. 

    Keeping an eye on your beer will help it last longer, but there are three main opponents to avoid when drinking beer: sun, air, and any pathogens present. Beer can be ruined by the sun's ultraviolet rays, so it's best to store it somewhere dark for as long as possible.

    The compounds in the plant undergo a chemical reaction when exposed to UV light, resulting in a distinct flavour. Oxygen reacts with other elements, resulting in variations in beer flavour. Since bacteria are killed by alcohol, modern brewing equipment has helped diminish the threat of contamination. The yeast used to brew ales is similarly impacted by the cold, as its reproductive cycle is slowed.

    FAQs About Brewed Beer

    Beer can last for a long time, but its flavour and quality will decline. Generally, beer is at its best within the first few months after brewing.


    Not necessarily. Unlike some other food and drink products, beer is not required to have an expiration date. However, some breweries label their beer with a "best by" or "bottled on" date to give consumers an idea of how fresh the beer is.


    Expired beer is not necessarily harmful, but its flavour and quality will deteriorate over time. It may taste stale, flat, or have off flavours.


    Beer should be stored in a cool, dark place to slow oxidation and maintain freshness. Exposure to light and heat can cause the beer to degrade more quickly.


    While storing beer in the fridge is generally a good idea, it can still go bad if it's kept in there for too long. This is especially true for beers that are not pasteurised or have a high hop content, which can make them more susceptible to spoilage. It's best to drink your beer within a few months of purchasing it, regardless of whether it's been stored in the fridge.
