What has a longer shelf life, canned beer or bottled beer?

Monday, February 13, 2023
Canned beer typically has a longer shelf life compared to bottled beer, with a shelf life of up to 9 - 12 months months before flavours can begin to deterioriate slowly. This is due to the tighter seal provided by the can, which helps to protect the beer from light, air, and other elements that can impact the flavor.

 Additionally, the aluminium used in cans acts as a barrier to oxygen, which can further extend the shelf life. The main advantage of canned beer over bottled beer is the increased protection from light and air, which can cause the beer to spoil more quickly. Cans also have the added benefit of being more sustainable and easier to recycle.

One potential disadvantage of cans is that they can have a slight metallic taste, which can affect the flavor of the beer. Beer bottle caps, though bloody brilliant, will over time allow oxygen to enter the beer. In contrast, bottled beer is more susceptible to spoilage due to its exposure to light and air. 

Many brewers use brown glass bottles or offer UV protection on clear or green glass bottles to reduce the impact of light on the beer. Beer bottles which are exposed to too much sunlight radiation are said to be 'skunked'.

Why does beer taste taste better when drunk from a glass rather than from an aluminium can?


Beer can taste better when consumed from a glass rather than an aluminum can for a few reasons. 

Firstly, the sense of smell plays a significant role in the perception of taste, and the aroma of the beer is more pronounced when it's in a glass. When drinking from a can, the beer is not exposed to the air, which can limit the release of aromas. 

Additionally, aluminium can have a slight metallic taste, which can affect the flavour of the beer. This metallic taste can be particularly noticeable in beers with a lighter flavor profile, and can detract from the overall taste experience. 

Glass, on the other hand, does not have an impact on the flavor of the beer and allows for the full range of aromas to be experienced. Drinking from a glass can also be a more visually appealing experience, as the beer can be seen in its full glory, which can enhance the overall enjoyment of the beer.

It's also worth noting that some beer styles, such as stouts and porters, are often served in a specific type of glass, such as a tulip glass or a snifter, that is designed to enhance the flavor and aroma of the beer. 

One simply cannot get that experience when drinking from a can! 

Why is aluminium used for making beer cans?


Aluminium is widely used for making beer cans because it offers several advantages over other materials. 

Here are some of the reasons why aluminium is the preferred material for beer cans: 

  • Lightweight: Aluminum is a lightweight material, making it easier and more cost-effective to transport and distribute. 
  • Durability: Aluminum cans are strong and durable, which helps to protect the beer from physical damage during transport and storage. 
  • Barrier properties: Aluminum is an excellent barrier to light, air, and other elements that can impact the flavor and quality of the beer. 
  • Recyclability: Aluminum is a highly recyclable material, and the recycling rate for aluminum cans is very high. This makes aluminum cans a more sustainable option compared to other packaging materials. Cost-effective: Aluminum is relatively cheap to produce compared to other materials, making it a cost-effective option for beer companies. 
  • Versatile: Aluminum can be molded and shaped into different forms, allowing for innovative packaging designs and branding opportunities. 
  • Quick cooling: Aluminum conducts heat well, which makes it possible to quickly cool down canned beer on hot summer days. 

Which beer company first introduced canned beers to the market?

Canning beer was first introduced by the American beer company Krueger's in 1935. The circumstances leading up to this introduction were influenced by several factors, including the Prohibition period and technological advancements in the canning industry. 

Before Prohibition, beer was primarily sold in kegs and bottles, and the canning of beer was not yet a common practice. However, with the passage of the 18th Amendment to the US Constitution, the production and sale of alcohol was banned, leading to a decrease in the demand for beer. 

During this time, the canning industry was undergoing significant advancements, and canning technology was being developed for a variety of food and beverage products. 

In 1935, Krueger's saw an opportunity to use this technology to can beer, and they became the first beer company to do so. The introduction of canned beer was a major turning point for the beer industry, as it allowed for more convenient and efficient distribution and storage. The lightweight and durable nature of cans made them an ideal packaging material, and they soon became popular among beer drinkers. 

After Prohibition was lifted, the demand for beer increased, and more beer companies began to adopt the canning of beer. 

Today, cans are a ubiquitous part of the beer industry, and they continue to be used by beer companies worldwide.
