What is Unpasteurized Beer?
If you think that unpasteurized beer is similar to unpasteurized milk, you’re correct. But do you know what pasteurization involves? Probably not. So here is a simple explanation to begin: pasteurization is a process that heats a liquid—such as beer—to a temperature that kills off bacteria and dangerous microbes. That is around 212°F (100°C). Many brewers have used pasteurization as a means of stabilizing and sterilizing their brews without needing to change the beer.
Here is where emphasis on many brewers is needed. Craft breweries rarely pasteurize their beers, while many commercial and domestic beers—Budweiser (excluding the Budvar variety), Coors, Millers—are always pasteurized. Keg or bottle form, most products from domestic brands, even Heineken, are pasteurized.
So when you see that beer is unpasteurized, it means that the pasteurization step was skipped.
A Brief History of Unpasteurized Beer
Did you know that the process of pasteurization was first invented by Louis Pasteur, a French scientist who sought to make French beer tastier? He originally started his work in the grape fields of France, but he later moved on to ale. Pasteur was studying diseases that were present in beer, and he noted that beer fermented at higher temperatures would spoil faster.
Pasteur decided to do something about that. In 1873, Pasteur patented his design for pasteurization, a process that revolutionized beer processing and packaging.

Is Unpasteurized Beer Safe to Drink?
Most beers, regardless if they are filtered or unfiltered, pasteurized or unpasteurized, have been sterilized. When they are left unpasteurized, this means that any microorganisms in the beer are killed off by the alcohol. Oftentimes, it also has probiotics that can boost your gut health, though the alcohol will negate that if you drink too much.
Furthermore, the yeast present in unpasteurized bottles of beer will grow unfettered, and that elevates the flavor of the beer exponentially. When comparing pasteurized vs unpasteurized beer flavor, people often say the latter is ambrosial.
What is Its Shelf Life?
The main benefit of pasteurization is that it extends the shelf life of the beer. A bottle of pasteurized beer can remain fresh-tasting for about six to nine months. Some can last up to a year in the refrigerator. Meanwhile, unpasteurized beers can last anywhere between 60 to 180 days, depending on the packaging and if it is kept in constant refrigeration.
If you purchase it, make sure you don’t let it get hot; no one likes skunky, off-tasting beer!
