How Do Brewers Like BrewDog Make Over 50 ABV Beers Exactly?

In the ever-evolving world of craft beer, one of the most intriguing techniques for producing beers with extremely high alcohol content (over 50 ABV) involves a combination of freezing and fortification with grain alcohol. Breweries such as BrewDog and others have pushed the boundaries of what is possible, creating beers that are both formidable and fascinating.

The Technique of Freezing and Irrigation

In addition to the freezing method mentioned, beers with extraordinarily high alcohol percentages are often fortified with grain alcohol to further elevate the ABV level. This process is meticulous and involves multiple steps, ensuring that the final product is of the highest quality.

The Legend of Eisbock: Discovered By Accident

A notable technique that proves the viability of producing high ABV beers is the Eisbock, a legendary beer style that was discovered by accident. The process begins with a higher ABV beer, in the 10-12 range, which is carefully frozen. Water freezes first, leaving the more concentrated alcohol to remain.

There are two main methods for achieving this result. One involves pouring the beer into a container and allowing it to freeze, after which the ice is removed. An alternative method is to use a plastic bucket that can withstand the expansion of the ice, allowing the liquid to be drained out from the bottom. The remaining liquid is higher in alcohol content, and thus, the beer is concentrated.

This process, though challenging, is not uncommon among craft brewers. Multiple breweries, including Barlow Brewing, have successfully applied this technique to produce Eisbock. It is a testament to the creativity and technical skill of modern brewers.

BrewDog: Setting Standards in High ABV Beers

BrewDog, a well-known Scottish microbrewery, has set the benchmark for extreme ABV beers. Their Tactical Nuclear Penguin, with an ABV of 62%, was once considered the strongest beer in the world. Although it is no longer the absolute champion, it remains a symbol of the brewery's commitment to pushing boundaries.

Despite its impressive strength, producing a product like Tactical Nuclear Penguin is not without its challenges. Brewery notes emphasize the importance of starting with a clean, high-quality base beer to ensure the final product is free from off-flavors. This meticulous attention to detail is crucial in the creation of any high ABV beer.

Striving for Perfection: The Art of Eisbock

The production of Eisbock demands perfect craftsmanship. As highlighted by BrewDog, maintaining a clean beer is paramount. Any impurities or off-flavors can be amplified during the ice removal process, leading to an unsatisfactory end product. This fact underscores the need for rigorous quality control and attention to brewing purity.

One day, it would be remarkable to sample a bottle or have a pint of Tactical Nuclear Penguin. Its rich, concentrated flavor and bold ABV would certainly be a remarkable experience for any beer enthusiast.

For those interested in exploring the realm of high ABV beers, understanding the techniques behind Eisbock, as well as the dedication of breweries like BrewDog, can offer a deeper appreciation for the craft of brewing. Whether through freezing, fortification, or combining both methods, pushing the limits of ABV continually challenges and fascinates the world of craft beer.
