Flanders Sour

The sour red/brown beers of Flanders can be considered as two different styles, or two ends of a single style continuum, depending on how you choose to view the issue. They are a clearly–defined sour ale subtype, one with strong historical traditions. Their character blends rich malt with tartness, and usually some fruity character as well. Oak aging is common in the traditional production of the style and therefore is often evident in the character. Many examples are also aged on fruit. At the red end of the style, the classic is Rodenbach at the brown end it is Liefmans, and there are several very good examples in between. (RateBeer)
