Fermentation characteristics
Brettanomyces-produced aromas and flavors should be present in Oud Reds and may be present in Oud Bruins. Fruity esters expressed as cherry or green apple attributes are apparent. Very slight levels of ethyl acetate (red apple) may be present. Overall flavor of Oud Bruin is fundamentally characterized by medium low to high lactic sourness. Many versions express very low to medium acetic sourness and aroma; acetic sourness may also be absent.
Additional guideline notes & competition context
These beers showcase a pleasant, complex, vinous character and refreshing acidity. Oaky or woody flavors may be pleasantly integrated. Flavors of wine or distilled spirits associated with used barrels should not be present. These beers are often a blend of old and young beer to create the brewer’s intended flavor balance.
