Sour ales make ya’ pucker!

A customer returned to the store, noting that a bottle of ale they’d purchased was sour. Upon further investigation, we discovered that the bottle in question was Vichtenaar, a Flanders red style.


Some beers, such as Flanders red ales, are supposed to taste sour. For example, Vichtenaar is a refreshingly sour ale that’s matured in oak casks for a minimum of eight months and bottled without any further blending. it’s a traditional ale with intentionally fruity-sour-oak notes and refreshing aftertaste. And, as the brewer describes it, this beer is lively and layered with notes of Madeira, vanilla, and oak.

An intentionally sour beer…really?
Sour may be a crazy descriptor to attract people to beer, but what about “bitter”? There are tons of hop-heads out there seeking the next big bitter. Like bitter, sour has a drying effect on the palate. Sour can be like the biting fruit of a lemon, sweet vinegar, or even sour wood — hence, sour beers have a wide range of flavors.


About Belgian & American sour ales
Belgian sour ales are interesting and balanced, with fruit and wood notes that make them refreshing. Belgian brewers age their sour beers in unlined wooden vessels instead of modern stainless-steel. The wild yeasts and microflora that live in the crevices of the wood take their time and create a complex, tart result.

American craft brewers started experimenting with sour in the mid 1990s; generally attempting to copy Belgian lambics, a style with sharp acidity, barnyard funk, and fruity notes.

Why do sour ales cost more than a typical beer?
Sour ales cost more for a few reasons— the wild yeasts and bacteria are slow, some take 18 months or longer to reach fruition; and the wild yeasts and bacteria are tenacious, so brewers have to take care to isolate them from the rest of the brews or risk cross-contamination and all-out funktification of their brewery.

Serving sour ales
Serve sour ales in a flute, snifter, tulip, or oversize wine glass. Drink them at cellar temperature (45–50°F).

About sour beer styles

Oud bruin ales/Flanders brown ales are light to medium-bodied, deep copper to brown in color. Extremely varied, these beers are characterized by a slight vinegar or lactic sourness and spiciness to smooth and sweet. A fruity-estery character is apparent with no hop flavor or aroma. Low to medium bitterness. Oak-like or woody characters may be integrated into the overall palate — and while Flanders red ales are aged in oak, the brown ales are warm-aged in stainless steel. Typically old and new Brown ales are blended, like lambics. These are old ales and have roots back to the 1600s when they were brewed as a “provision beer” that would develop some sourness as it aged. 4-8% abv.

Note: We had the opportunity to sample a young and 20-year vintage of Liefman’s Goudenband, a delicious oud bruin, at an industry beer tasting event in 2007. While the young beer had its characteristic sour, the flavors in the vintage had melded, was incredibly smooth, and exhibited a reduced sour character.


Flanders red ales are commonly referred to as the “red” beers of West Flanders. Belgian Red Beers are typically light-bodied brews with reddish-brown colors. They are infamous for their distinct sharp, fruity, sour, and tart flavors that are created by special yeast strains. Very complex beers, they are produced under the age old tradition of long-term cask aging in oak, and the blending of young and old beers. This style is indigenous to West Flanders, Belgium, and was typified by the products of the Rodenbach brewery, established in 1820. 4-8% abv

Gueuze is a traditional Belgian blend of young and old Lambics, which are bottle after blending, then aged for 2-3 years to produce a dryer, fruitier, and more intense style of Lambic. There is no hop character, some are filtered and force carbonated. They have an intense sourness. Gueuze and lambics stem from a farmhouse brewing tradition that is several centuries old. 4-6% abv

Berliner Weisse is a very pale, sour, refreshing, low-alcohol wheat ale. This style is a regional specialty of Berlin, and was referred to by Napoleon’s troops in 1809 as “the Champagne of the North” due to its lively and elegant character. Only two traditional German breweries still produce the style. 2.8-5% abv
