71. Belgian-Style Flanders Oud Bruin or Oud Rood Ale

Belgian Flanders Oud Bruin or Rood Ales are copper to very dark. The Flemish word "oud bruin" means old brown, and "oud rood" is old red. SRM/EBC color values can be misleading because the red spectrum of color is not accurately assessed by these measurement systems. Chill haze is acceptable. Bottle conditioned versions may appear cloudy when served. Fruity esters expressed as cherry or green apple attributes are apparent. Hop aroma and flavor are not present. Hop bitterness is present to be very low to medium-low, though acidity and wood aging (if used) may mask higher bitterness levels. Roasted malt aromas and flavors including a cocoa-like character are acceptable at low levels. A very low level of malt sweetness may be present and balanced by acidity from Lactobacillus. Brettanomyces-produced aromas and flavors should be absent or very low. Oaky or woody flavors may be pleasantly integrated into overall palate. Overall flavor is characterized by low to high lactic sourness. Flavors of wine or distilled spirits associated with used barrels should not be present. Bottle conditioned versions are often a blend of old and young beer to create the brewer's intended flavor balance. Some versions may be more highly carbonated. Body is light to medium-light with a refreshing mouthfeel.
