Unpasteurized Beer: Safe Or Not?

Pasteurization is the process of heating beer to a temperature that kills any living microbes. It is used by some brewers to sterilize and stabilize their product without changing its chemistry or flavor. However, craft breweries often choose not to pasteurize their beers, as the rapid heating and chilling can negatively impact the flavor. So, is it safe to drink unpasteurized beer? Yes, as long as it has been stored properly and kept cool. Unpasteurized beer has live yeast and enzymes, which are good for gut health, and the alcohol content kills any harmful bacteria.

Unpasteurized beer is safe to drink as long as it's stored properly and kept cool

Unpasteurized beer is safe to drink, but it must be stored properly and kept cool. Pasteurization is a process that heats a liquid to a temperature that kills bacteria and harmful microbes. Beer is usually pasteurized by running the cans and bottles through a hot water spray of around 140°F (60°C).

Unpasteurized beer skips this step, so it needs to be continuously chilled to remain fresh. It should be kept at 3°C from the time it's bottled or kegged until it's consumed. It should also be consumed within 45 to 60 days of the production date.

Unpasteurized beer has several benefits. Firstly, it has a fresher and more flavourful taste compared to pasteurized beer. The rapid heating and chilling process of pasteurization can cause a loss of aroma and flavour. Secondly, unpasteurized beer contains live yeast and enzymes, which are good for gut health. The alcohol content also kills any harmful bacteria.

However, there are some drawbacks to unpasteurized beer. It has a shorter shelf life, typically lasting between 60 to 180 days, depending on packaging and refrigeration. It also needs to be continuously chilled, which can be inconvenient and expensive.

Overall, unpasteurized beer is safe to drink as long as it is stored properly, kept cool, and consumed within a reasonable timeframe.

Pasteurization kills bacteria and microbes, but it can also negatively impact the flavour of the beer

Pasteurization is a process that heats beer to a temperature that kills bacteria and microbes (around 100°C or 212°F). While this process is used to sterilize and stabilize beer, it can also negatively impact the flavour. The rapid heating and chilling can cause a beer's aromas to be lost and its flavour to become 'flattened'.

Those who prefer unpasteurized beers argue that the process gives the brew a 'burnt sugar' flavour and ruins the true flavour of the beer. Unpasteurized beer is often considered to have a better flavour because it hasn't undergone this process.

However, it's important to note that the decision to pasteurize or not is not just about flavour. Pasteurization extends the shelf life of beer and helps with standardization of taste. It also means the beer can be kept at room temperature without spoilage. Unpasteurized beers, on the other hand, need to be continuously chilled to remain fresh and have a shorter shelf life.

Ultimately, the choice between pasteurized and unpasteurized beer comes down to a balance between preserving the flavour and achieving a longer shelf life.

Unpasteurized beer has a shorter shelf life than pasteurized beer

Unpasteurized beer, on the other hand, has a shorter shelf life and needs to be continuously chilled and consumed as close to the production date as possible. As a rule, unpasteurized beer should be consumed within 45 to 60 days of the production date. Some unpasteurized beers can last anywhere between 60 to 180 days if kept in constant refrigeration.

The shorter shelf life of unpasteurized beer is due to the absence of the pasteurization process, which kills bacteria and prevents further fermentation. Without pasteurization, unpasteurized beer is more susceptible to contamination and must be kept refrigerated at all times to prevent spoilage.

The main benefit of unpasteurized beer is that it often has a fresher taste compared to pasteurized beer as it has not been sitting around for as long. Additionally, the yeast present in unpasteurized bottles of beer can grow unfettered, elevating the flavor of the beer exponentially.

Unpasteurized beer has live yeast and enzymes, which are good for gut health

Unpasteurized beer has a plethora of health benefits, particularly for gut health. The process of pasteurization involves heating a liquid to a temperature that kills off bacteria and dangerous microbes. While this process is useful for sterilization, it also removes the live yeast and enzymes that are beneficial for gut health.

Unpasteurized beer contains live yeast, which is a type of beneficial bacteria known as lactobacillus. This bacteria has probiotic effects, similar to those found in fermented foods like yogurt or kefir. Probiotics are known to have a positive impact on gut health, and can help to improve digestion and enhance the immune system.

In addition to live yeast, unpasteurized beer also contains enzymes that can aid in digestion. The hops present in beer possess digestive properties such as gastric acid, pancreatic enzymes, and cholecystokinin, a gut hormone that is released after a meal. Unpasteurized beer also contains B vitamins, which are essential for maintaining a healthy gut.

The benefits of unpasteurized beer for gut health are significant. By consuming beers that have not been pasteurized, individuals can take advantage of the live yeast and enzymes present in the beverage, which can improve digestion, enhance immune function, and promote a healthy gut microbiome.

Craft breweries tend to produce unpasteurized beer, while macro breweries tend to pasteurize their beer

Pasteurization is the process of heating beer to a temperature that will kill any living microbes. It is used by some brewers to sterilize and stabilize their product without changing the chemistry or flavor. The modern technique was perfected by Louis Pasteur in 1873, and it was revolutionary at the time as refrigeration was uncommon and beer had a tendency to spoil. Pasteurization is also used to prevent infections from packaged beer.

Some people in the modern beer community decry the process of pasteurization. They argue that the process gives the brew a 'burnt sugar' flavor and that pasteurization and too much filtering ruin the true flavor of the beer. However, without a side-by-side comparison of a pasteurized and unpasteurized sample of the same beer, these changes in flavor are speculation.

On the other hand, macro breweries often pasteurize their beer to ensure shelf stability and prevent quality issues. Common methods of pasteurization include flash pasteurization, which heats the beer quickly and then cools it down immediately, and tunnel pasteurization, which involves heating the finished product (beer in a bottle, keg, etc.) to kill bacteria.
