  • Color: Copper to very dark. SRM/EBC color values can be misleading because the red spectrum of color is not accurately assessed by these measurement systems.
  • Body: Low to medium-low with a refreshing mouthfeel
  • Malt Flavors & Aromas: Roasted malt aromas and flavors including cocoa are acceptable at low levels. A very low level of malt sweetness may be present and balanced by acidity from Lactobacillus.
  • Hop Flavors & Aromas: Not present
  • IBUs/Bitterness: Very low to medium-low, though acidity and wood aging (if used) may mask higher bitterness levels.
  • Fermentation Characteristics: Brettanomyces-produced aromas and flavors should be absent or very low. Fruity esters expressed as cherry or green apple attributes are apparent. Overall flavor is characterized by low to high lactic sourness. Some versions may express very low to low acetic sourness and aroma.
  • Common Ingredients: A base of Vienna and/or Munich malts, light to medium cara-malts, and a small amount of Special B are used with up to 20% maize. Low alpha acid continental hops are commonly used (avoid high alpha or distinctive American hops). Saccharomyces, Lactobacillus and Brettanomyces (and acetobacter) contribute to the fermentation and eventual flavor.
  • Commercial Examples: Cuvée des Jacobins Rouge, Duchesse de Bourgogne, Rodenbach Grand Cru, Rodenbach Klassiek, Vichtenaar Flemish Ale
