Key takeaways
The quick answer: How long does beer stay fresh?
Unopened beer typically stays fresh for 6-9 months beyond its best-before date when stored properly, and often even longer if refrigerated. Once opened, beer is best enjoyed within 1-2 days. It won't usually make you ill, but it will gradually lose its carbonation, aroma, and flavour.
Beer freshness at a glance
| Beer type | How long it stays fresh | Best storage |
|---|---|---|
| Unopened bottle or can | 6-9 months beyond the best-before date (often longer if refrigerated) | Cool, dark place or fridge |
| Opened bottle or can | 1-2 days | Refrigerate and reseal if possible |
| Keg or draught beer | 30-45 days (pasteurised) or 5-7 days (unpasteurised) once tapped, with proper dispensing and refrigeration | Chilled keg with CO₂ system |
| Fresh draught in a Pinter | Up to 30 days | Keep refrigerated and pour fresh from the Pinter |
Best before vs gone off: What the date actually means
| Best before | Gone off |
|---|---|
| Indicates peak quality, not safety | Indicates the beer has spoiled |
| Beer is often still safe to drink after the date if stored correctly | Should not be consumed |
| Flavour, aroma, and carbonation may gradually fade | May smell sour, taste stale, or show signs of contamination |
| It's legal to sell products past their best-before date in the UK if they're still fit for consumption | Spoiled beer should always be discarded |
The date on the label isn't a deadline. If your unopened beer has been stored in a cool, dark place, it may still taste great beyond its best-before date. Instead of relying on the date alone, use your senses before deciding whether to enjoy it.
How long does beer stay fresh - Based on styles
Beer freshness depends on the style. Some beers are best enjoyed within a few weeks of packaging, while others can hold their flavour for several months when stored properly.
1. IPA
Best within: 30-60 days
IPAs are packed with hop aromas that deliver citrus, tropical fruit, and floral notes. These hop compounds fade quickly, which is why fresh beer is especially important for hop-forward styles. The sooner you drink an IPA, the closer it will taste to the brewer's original intent.
2. Lager
Best within: 60-120 days
Lagers tend to have a cleaner flavour profile and fewer delicate hop aromas than IPAs, which helps them stay fresh for longer. Their balanced malt character and lower hop intensity make them less susceptible to flavour loss, allowing them to maintain their crisp, refreshing taste for several months when stored properly.
3. Stout
Best within: 90-180 days
The roasted malt flavours found in many stouts are generally more stable over time. Coffee, chocolate, and caramel notes often hold up well, meaning stouts can remain enjoyable for several months after packaging.
4. Cider
Best within: 90-180 days
Most ciders retain their crisp apple character for longer than heavily hopped beers. Proper storage away from heat and sunlight helps preserve flavour, carbonation, and overall freshness.
That said, many breweries use a 30-day freshness window as a benchmark for delivering beer at its absolute best.
Why beer goes stale
Oxidation
Oxidation happens when beer is exposed to oxygen after brewing or packaging. As oxygen interacts with the beer, fresh flavours begin to fade and are replaced by dull, cardboard-like or papery notes. This is one of the main reasons fresh beer tastes better than beer that has been sitting around for too long.
Light Strike
Beer doesn't get on particularly well with sunlight. When UV light reaches the beer, it reacts with compounds from the hops and creates a distinctive "skunky" smell and taste. This process, known as light strike, can happen surprisingly quickly, which is why many breweries use dark bottles or cans to protect freshness.
Temperature Fluctuations
Beer prefers a stable environment. Repeated warming and cooling speeds up the chemical reactions that gradually break down flavour and aroma compounds. Even a well-made beer can lose its character faster when stored in inconsistent temperatures.
Time Since Packaging
The fresh beer brewing process is designed to deliver beer with vibrant hop aromas, balanced flavours, and the right level of carbonation. As weeks and months pass, those qualities naturally begin to diminish. While some beer styles age well, most are at their best when enjoyed as fresh as possible.
How to tell if your beer has gone off
Before you take a sip, give your beer a quick once-over.
Watch out for these signs:

Meet Pinter - The machine that keeps beer fresh for 30 days
Pinter fresh beer machine uses a closed brewing, conditioning, and dispensing system, so the beer stays in the same vessel from start to finish, limiting exposure to oxygen that can dull flavour and aroma.
As the beer ferments, naturally produced CO2 creates a protective layer that helps preserve freshness. Combined with Pinter's Fresh Press technology and refrigerated storage, this controlled environment helps maintain brewery-fresh flavour for up to 30 days after brewing.
The result is fresh beer on tap at home without the rapid flavour loss often associated with traditional home brewing. Pinter also regularly runs offers where the machine is available at no upfront cost when purchased with beer packs, making it easier to get started.

This juicy, hop-forward beer delivers vibrant tropical fruit and citrus flavours, with the soft, hazy body that has made the style so popular.

Enjoyed fresh, this Hazy IPA showcases the bright, expressive character the brewer intended, with a smooth mouthfeel and a refreshing finish.
Fresh beer makes all the difference
The moment you crack open a bottle or can, freshness starts to disappear. Oxygen enters, carbonation escapes, and those bright beer flavours begin to fade. While an opened beer is usually safe to drink for 1-2 days if refrigerated, it won't taste as the brewer intended. Expect flatter carbonation, muted aromas and stale, oxidised flavours.
That's the trade-off with packaged beer: once it's open, you're committed to finishing it. Pinter is different. Freshly brewed beer is dispensed without opening the whole batch, so the remaining beer stays fresh for up to 30 days when stored as directed.
Fresh Beer at Home with Pinter
If freshness matters to you, Pinter makes it easy to enjoy fresh beer at home. Simply brew from a Fresh Press kit and enjoy beer that stays fresh for up to 30 days after brewing.
