What makes a wild beer?

Answered by Dustin Gorski

A wild is a truly unique and adventurous brew that pushes the boundaries of traditional beer styles. What sets wild beers apart is the use of wild yeasts, primarily Brettanomyces, which are collected in various ways. These yeasts are often found in the natural environment, such as on the skins of fruits or in the air around us. They bring a whole new level of complexity and funkiness to the beer, resulting in a truly one-of-a-kind drinking experience.

One method of collecting wild is by scraping the skin of a fruit, like a strawberry, and capturing its microflora. This process involves carefully selecting the ripest and most flavorful fruit, then gently scraping a small portion of its skin. The collected material is then transferred to a sterile container, where it undergoes a fermentation process to cultivate and isolate the wild yeast. This yeast can then be used in the process to create a beer with distinct fruity and funky flavors.

Another way to acquire wild yeast is by purchasing a wild yeast culture from a laboratory. These cultures are often cultivated from specific regions or unique sources, like the bark of a certain tree or the flowers of a particular plant. These lab-grown yeasts offer a more controlled approach to wild beer production, allowing brewers to experiment with specific flavor profiles and characteristics.

Once the wild yeast is obtained, it is introduced into the wort during the fermentation process. The yeast interacts with the sugars in the wort, converting them into and carbon dioxide, just like conventional brewing. However, the wild yeast brings its own set of flavors and aromas to the beer, resulting in a range of interesting and unpredictable outcomes.

One of the key characteristics of wild beers is the funky flavors and aromas they exhibit. Brettanomyces, in particular, is known for producing unique compounds that can result in flavors reminiscent of barnyard, horse blanket, or even sweaty socks. While these descriptions may not sound appealing, they contribute to the complexity and depth of the beer, creating an intriguing drinking experience for those who appreciate the unconventional.

In addition to the funky flavors, wild beers often showcase a range of other flavor profiles. Fruity esters, spicy phenols, and tart or sour notes are also common in these brews. The combination of wild yeast, varied fermentation temperatures, and extended aging can result in a myriad of flavors that evolve over time, making each bottle a truly unique experience.

Wild beers are not for everyone, as their unconventional flavors can be an acquired taste. However, for those willing to explore the boundaries of traditional brewing, they offer an exciting and rewarding journey into the world of experimental and artisanal beers.

What makes a wild beer truly special is the use of wild yeasts, primarily Brettanomyces, collected in diverse ways. These yeast strains bring a range of funky and complex flavors to the beer, resulting in a unique and adventurous drinking experience. Whether obtained from scraping the skin of a fruit or purchasing a lab-grown culture, the wild yeasts used in these beers contribute to a wide array of flavors and aromas that are not typically found in conventional brewing. So, if you're up for a wild ride and ready to embrace the unexpected, give a wild beer a try and discover a whole new world of flavors.
