Oud Bruins, not restricted to, but concentrated in Flanders, are light to medium-bodied, deep copper to brown in colour. They are extremely varied, characterized by a slight vinegar or lactic sourness and spiciness to smooth and sweet. A fruity-estery character is apparent with no hop flavor or aroma. Low to medium bitterness. Very small quantities of diacetyl are acceptable. Roasted malt character in aroma and flavor is acceptable, at low levels. Oak-like or woody characters may be pleasantly integrated into overall palate. Typically old and new Brown ales are blended, like Lambics.
Average alcohol by volume (abv) range: 4.0-8.0%
