The distinction between Flanders Red Ale and Oud Bruin, as categorized by non-Belgian beer writers, is primarily based on the region of production and the aging process. Flanders Red Ales are generally brewed in West Flanders and undergo aging in oak, while Oud Bruin is typically aged in steel.
Flanders Red Ales, true to their name, originate from the Flanders region of Belgium, specifically West Flanders. These beers are known for their vibrant red color, complex flavors, and tartness. They are often described as having a sour or acidic character, with notes of red fruit, oak, and vinegar. The aging process in oak barrels lends additional depth and complexity to the beer, as it allows for the development of distinct flavors and aromas over time.
On the other hand, Oud Bruin, meaning “old brown” in Dutch, is also a style of beer hailing from the Flanders region. Oud Bruin is typically characterized by its deep brown color, malty sweetness, and a more restrained acidity compared to Flanders Red Ales. These beers often exhibit flavors of caramel, dark fruit, and a subtle tartness. Unlike Flanders Red Ales, Oud Bruins are commonly aged in stainless steel tanks instead of oak barrels. This results in a cleaner and crisper profile, allowing the malt flavors to shine through.
While the distinction between Flanders Red Ale and Oud Bruin is not universally agreed upon, it can be useful in understanding the general characteristics of these beers. However, it is important to note that there is some overlap between the two styles, with variations existing within each category. Brewers may have their own interpretations and methods of production, leading to a diverse range of flavors and profiles within both Flanders Red Ales and Oud Bruins.
As a sommelier and brewer, I have had the opportunity to taste and compare various examples of Flanders Red Ales and Oud Bruins. One memorable experience was trying Rodenbach Grand Cru, a renowned Flanders Red Ale known for its complex blend of flavors. The beer showcased a beautiful ruby color and a pronounced tartness that was balanced by a rich malt backbone. The oak aging contributed a subtle vanilla and woody character, adding depth to the overall profile.
In contrast, I have also enjoyed the delightful nuances of an Oud Bruin such as Liefmans Goudenband. This beer possessed a deep brown color with a slightly sweet aroma of caramel and dark fruit. The tartness was more subdued compared to Flanders Red Ales, allowing the malt flavors to take center stage. The absence of oak aging resulted in a cleaner and crisper finish, making it a refreshing and enjoyable brew.
To summarize, the difference between Flanders Red Ale and Oud Bruin lies in the region of production and the aging process. Flanders Red Ales are typically brewed in West Flanders and aged in oak, imparting a sour and complex character. Oud Bruins, on the other hand, are often aged in steel tanks and offer a maltier and slightly less tart profile. However, it is important to note that there can be variations within each style, and individual brewers may have their own interpretations. Exploring different examples of these beers can provide a deeper understanding and appreciation for the unique flavors and traditions of Belgian brewing.
