The distinction between Flanders Red Ale and Oud Bruin, as categorized by non-Belgian beer writers, is primarily based on the region of origin and the aging process of these beers. Flanders Red Ales are said to be brewed in West Flanders and are typically aged in oak, while Oud Bruin is generally aged in steel.
Flanders Red Ale, as the name suggests, originates from the Flanders region in Belgium, specifically West Flanders. These beers are known for their deep red color, complex flavors, and tartness. They are typically brewed using a combination of pale malts and specialty malts, which contribute to their rich and malty character. The use of specific yeast strains, such as Brettanomyces, adds a unique flavor profile, including fruity and funky notes.
The aging process of Flanders Red Ale plays a significant role in its development. After primary fermentation, the beer is often aged in oak barrels or foeders, large wooden vessels, for an extended period. This aging process allows the beer to undergo secondary fermentation and develop complex flavors through the interaction with the wood. The oak aging imparts additional flavors, including vanilla, tannins, and sometimes a subtle vinegar-like character. The result is a beer with a balance of sweetness, acidity, and oak character.
On the other hand, Oud Bruin, which translates to “old brown,” is also a traditional Belgian beer style originating from the Flanders region. These beers are typically darker in color, ranging from amber to dark brown, and have a more pronounced maltiness compared to Flanders Red Ales. Oud Bruin is often described as having a slightly sweet and sour taste, with more emphasis on the malty flavors.
Unlike Flanders Red Ales, Oud Bruin is typically aged in steel tanks or sometimes in oak, depending on the brewery. The use of steel for aging allows the beer to retain its malty character without the influence of oak flavors. This results in a cleaner and more straightforward profile, focusing on the malt sweetness and the subtle sourness from the fermentation process.
In terms of flavor profiles, Flanders Red Ales tend to have a more prominent tartness and sourness compared to Oud Bruin. The oak aging in Flanders Red Ales contributes to a more complex flavor profile with additional notes of fruitiness and wood. Oud Bruin, on the other hand, leans more towards a balance between malt sweetness and a milder sourness.
