What is a noted difference between Flanders Red and Oud Bruin in terms of acidity?

Flanders Red beers are known for their complex flavor profile, which often includes a prominent fruity character balanced by a certain level of lactic acidity. Oud Bruin, while also sour, tends to showcase a more malt-forward profile with less pronounced acidity in comparison to Flanders Red.

The key aspect distinguishing these two styles is the level of acetic acidity, which gives a vinegary quality to the beer. Flanders Red typically allows for a more intense sourness that can exhibit acetic notes, especially when compared to the maltier Oud Bruin, where the focus is more on the sweetness and body derived from the malt rather than the sourness. This results in Flanders Red being perceived as having a sharper acidity and, at times, more complexity from the acetic fermentation.

Thus, stating that Flanders Red is more acetic and vinegary than Oud Bruin accurately captures the distinctive character of these two styles, highlighting the differences in sourness and acidity that are fundamental to their profiles.
