Blue Moon Beer: Safe To Drink After Expiry?

Blue Moon is a popular beer, but what happens if it expires? Is it safe to drink? Beer slowly changes over time, and low-gravity beers like Blue Moon can become stale and develop a wet cardboard taste. However, drinking expired beer is unlikely to be harmful to your health, and the worst-case scenario is that it doesn't taste good. The flavour may change, and it could give you a headache, but it won't make you sick. So, if you have a Blue Moon that's past its expiration date, you can try a sip and decide if you want to continue drinking it based on the taste.

Blue Moon uses a six-character expiration date

The expiration date is important for consumers to determine whether their beer is still good to drink. While drinking expired beer is not harmful to health, it may not taste as good as beer that is consumed before its expiration date.

Some people on Reddit have reported drinking Blue Moon that was two months past its expiration date and noticed an odd solid-like sediment. They also noted that the expiration date does not matter much, but they would not recommend drinking beer that is six months past its expiration date.

Another Reddit user received a box of Blue Moon with a date of May 14, 2019, and was unsure if it was the expiration date or the manufacturing date. Other users clarified that the date was the pull date, meaning a MillerCoors representative would pull it from the store after that date, and there is no harm in drinking the beer.

The health implications of drinking expired beer

However, there are a few things to keep in mind. Firstly, if the beer has lost its fizz, it is a sign that the seal was broken at some point, and the flavour will be affected. Secondly, if a non-tangy or non-acidic beer has a vinegary taste, it is an indication that bacteria have gotten in, and it should be discarded.

While drinking expired beer is usually safe, it is important to note that the taste of the beer may change over time. Beers that are past their prime may develop an unpleasant "wet cardboard" flavour, become overly sweet, or acquire the dreaded "skunky" taste, which is caused by a chemical reaction triggered by exposure to ultraviolet light.

To maintain the freshness and flavour of your beer, it is recommended to store it in a cool, dark place, preferably a refrigerator. If stored at room temperature, ensure that it is kept away from sunlight. Additionally, it is best to keep beers standing upright to minimise exposure to oxygen.

In summary, while drinking expired beer typically does not pose any serious health risks, it may result in an unpleasant taste experience. To avoid this, follow the storage recommendations provided, and try to consume beer as close to its "born on" date as possible.

The taste of expired beer

It's important to note that beer typically has a "'best before' date, not an expiration date. This means that it is still safe to drink after this date, but the flavour may have degraded.

In general, as beer ages, it becomes flatter and sweeter due to the oxidation of aroma and flavour compounds. A fresh lager, for example, will present bright hops flavour and refreshing bitterness, while an older lager will taste distinctly malty, sweet, and flat. Beers with hoppy characteristics, such as IPAs and pale ales, do not tend to age well and should be consumed fresh.

Very old beer may develop off-flavours described as "cardboard" or "vanilla-tobacco". It may also become chunky due to the formation of sediment, especially if exposed to temperature fluctuations. However, this sediment is harmless and simply a result of the beer being unfiltered.

While it is generally safe to drink expired beer, mould can still grow in old beer, especially if the bottle was dirty at the time of packaging or if the seal was broken. If there is mould in the beer, it is best to discard it.

The importance of light when storing beer

It is generally safe to consume expired beer, although it may not taste as good as it once did. However, storing beer properly is crucial to maintaining its unique flavour and ensuring quality. One of the most important factors to consider when storing beer is protecting it from light, especially direct sunlight.

Beer's greatest enemy is light, specifically direct sunlight, as it can cause chemical reactions that negatively impact the flavour of the beer. UV rays can react with hops in beer, producing a skunky flavour. This phenomenon, known as "lightstrike," occurs when ultraviolet and visible light rays initiate a photochemical reaction in the hop compounds, leading to the formation of 3-methyl-2-butene-1-thiol. The same chemical is also found in skunk spray, giving the beer an unpleasant taste.

To prevent lightstrike, it is essential to store beer in dark places, away from direct light sources. Brown bottles are commonly used by craft brewers as they effectively block out light under 500 nanometers, reducing the risk of lightstrike. On the other hand, green bottles only block ultraviolet light, while clear bottles offer no protection against lightstrike.

Cans are also an excellent option for light protection, as they completely block out light. Additionally, they have a tighter seal than bottles, preventing gases from escaping or entering the container. This helps to maintain the carbonation and freshness of the beer.

When storing beer, it is also crucial to maintain a consistent, cool temperature. Fluctuations in temperature can lead to premature aging, affecting the beer's taste and aroma. Ideally, beer should be stored at temperatures between 35°F and 45°F. Colder environments slow down the aging process, keeping the beer fresher for longer.

In summary, when storing beer, it is essential to keep it in a dark, cool place, away from direct sunlight and extreme temperature fluctuations. Proper storage ensures that the beer retains its unique flavour, texture, and carbonation, providing an optimal drinking experience.

The difference between expiration and pull dates

Pull dates and expiration dates are two different concepts that relate to the freshness and safety of food and beverage products. While both are important for consumers to consider, they serve distinct purposes and have different implications for product consumption.

Pull Date:

A pull date is designated by manufacturers or retailers as the last day a product should be available for purchase or consumption. It serves as a guideline for retailers to remove items from their shelves and for consumers to assess the product's freshness and safety. Pull dates are particularly important for perishable items, packaged foods, and beverages to ensure that consumers receive them at their optimal quality. The concept of a pull date has evolved to encompass not only product freshness but also food safety and regulatory compliance, aligning with consumers' expectations for transparency and quality assurance.

Expiration Date:

An expiration date, on the other hand, indicates the date after which a product is no longer considered safe to consume due to potential health risks. Consumption of food products after their expiration date is generally not recommended as the quality and safety of the product cannot be guaranteed. Expiration dates are especially important for products with strict freshness requirements, such as infant formula and some baby foods, which are required by federal law to bear expiration dates.

Key Differences:

The main difference between pull dates and expiration dates lies in their focus and level of criticality. Pull dates primarily indicate product freshness and quality, while expiration dates signify potential spoilage and health risks. Products with a pull date may still be safe for consumption shortly after the date passes, depending on storage conditions and product type. However, consumers should exercise discretion and inspect such products for any signs of spoilage. In contrast, products that have passed their expiration date are generally not recommended for consumption and should be discarded.

Application to Blue Moon Beer:

In the context of Blue Moon beer, the distinction between pull dates and expiration dates is essential for consumers. While an expired beer may not pose significant health risks if consumed shortly after the expiration date, it is essential to manage expectations regarding taste and quality. Beer can lose its optimal flavour and freshness over time, and consuming expired beer may result in a less enjoyable drinking experience. Therefore, it is advisable to prioritise drinking beer before its pull date to ensure optimal flavour and quality.
