23C – Oud Bruin

Overall Impression: A malty, fruity, aged, somewhat sour Belgian-style brown ale.

Aroma: Complex combination of fruity esters and rich malt character. Medium to medium-high esters commonly reminiscent of raisins, plums, figs, dates, black cherries or prunes. Medium low to medium high malt character of caramel, toffee, orange, treacle or chocolate. Spicy phenols can be present in low amounts for complexity. A sherry-like character may be present and generally denotes an aged example. A low sour aroma may be present, and can modestly increase with age but should not grow to a noticeable acetic/vinegary character. Hop aroma absent. Diacetyl is perceived only in very minor quantities, if at all, as a complementary aroma.

Appearance: Dark reddish-brown to brown in color. Good clarity. Average to good head retention. Ivory to light tan head color.

Flavor: Malty with fruity complexity and typically some caramel character. Medium to medium-high fruitiness commonly includes dark or dried fruit such as raisins, plums, figs, dates, black cherries or prunes. Medium low to medium high malt character of caramel, toffee, orange, treacle or chocolate. Spicy phenols can be present in low amounts for complexity. A slight sourness often becomes more pronounced in well-aged examples, along with some sherry-like character, producing a “sweet-and-sour” profile. The sourness should not grow to a notable acetic/vinegary character. Hop flavor absent. Restrained hop bitterness. Low oxidation is appropriate as a point of complexity. Diacetyl is perceived only in very minor quantities, if at all, as a complementary flavor. Balance is malty, but with fruitiness and sourness present. Sweet and tart finish

Mouthfeel: Medium to medium-full body. Low to moderate carbonation. No astringency.

Comments: Long aging and blending of young and aged beer may occur, adding smoothness and complexity and balancing any harsh, sour character. This style was designed to lay down so examples with a moderate aged character are considered superior to younger examples. As in fruit lambics, Oud Bruin can be used as a base for fruit-flavored beers such as kriek (cherries) or frambozen (raspberries), though these should be entered in the Classic-Style Fruit Beer category.

History: An “old ale” tradition, indigenous to East Flanders, typified by the products of the Liefman brewery (now owned by Riva), which has roots back to the 1600s. Historically brewed as a “provision beer” that would develop some sourness as it aged. These beers were typically more sour than current commercial examples. While Flanders red beers are aged in oak, the brown beers are warm aged in stainless steel.

Characteristic Ingredients: A base of Pils malt with judicious amounts of dark cara malts and a tiny bit of black or roast malt. Often includes maize. Low alpha acid continental hops are typical (avoid high alpha or distinctive American hops). Saccharomyces and Lactobacillus (and acetobacter) contribute to the fermentation and eventual flavor. Lactobacillus reacts poorly to elevated levels of alcohol. Water high in carbonates is typical of its home region and will buffer the acidity of darker malts and the lactic sourness. Magnesium in the water accentuates the sourness.

Style Comparison: A deeper malt character distinguishes these beers from Flanders red ales. The Oud Bruin is less acetic and maltier than a Flanders Red, and the fruity flavors are more malt-oriented.

23B – Flanders Red

Overall Impression: A sour, fruity, red wine-like Belgian-style ale with interesting supportive malt flavors and fruit complexity. The dry finish and tannin completes the mental image of a fine red wine.

Aroma: Complex fruity-sour profile with supporting malt that often gives a wine-like impression. Fruitiness is high, and reminiscent of black cherries, oranges, plums or red currants. There are often low to medium-low vanilla and/or chocolate notes. Spicy phenols can be present in low amounts for complexity. The sour aroma ranges from balanced to intense. Prominent vinegary acetic character is inappropriate. No hop aroma. Diacetyl is perceived only in very minor quantities, if at all, as a complementary aroma.

Appearance: Deep red, burgundy to reddish-brown in color. Good clarity. White to very pale tan head. Average to good head retention.

Flavor: Intense fruitiness commonly includes plum, orange, black cherry or red currant flavors. A mild vanilla and/or chocolate character is often present. Spicy phenols can be present in low amounts for complexity. Sour flavor ranges from complementary to intense, and can have an acidic bite. Malty flavors range from complementary to prominent, and often have a soft toasty-rich quality. Generally as the sour character increases, the malt character blends to more of a background flavor (and vice versa). No hop flavor. Restrained hop bitterness. An acidic, tannic bitterness is often present in low to moderate amounts, and adds an aged red wine-like character and finish. Prominent vinegary acetic character is inappropriate. Diacetyl is perceived only in very minor quantities, if at all, as a complementary flavor. Balanced to the malt side, but dominated by the fruity, sour, wine-like impression.

Mouthfeel: Medium bodied. Low to medium carbonation. Low to medium astringency, like a well-aged red wine, often with a prickly acidity. Deceivingly light and crisp on the palate although a somewhat sweet finish is not uncommon.

Comments: Long aging and blending of young and well-aged beer often occurs, adding to the smoothness and complexity, though the aged product is sometimes released as a connoisseur’s beer. Known as the Burgundy of Belgium, it is more wine-like than any other beer style. The reddish color is a product of the malt although an extended, less-than-rolling portion of the boil may help add an attractive Burgundy hue. Aging will also darken the beer. The Flanders red is more acetic (but never vinegar-like) and the fruity flavors more reminiscent of a red wine than an Oud Bruin. Can have an apparent attenuation of up to 98%.

History: An indigenous beer of West Flanders, typified by the products of the Rodenbach brewery, established in 1820 in West Flanders but reflective of earlier brewing traditions. The beer is aged for up to two years, often in huge oaken barrels which contain the resident bacteria necessary to sour the beer. It was once common in Belgium and England to blend old beer with young to balance the sourness and acidity found in aged beer. While blending of batches for consistency is now common among larger breweries, this type of blending is a fading art.

Characteristic 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.

Style Comparison: Less malty-rich than an Oud Bruin, often with more of a fruity-tart profile.

Vital Statistics:

OG:  1.048 – 1.057

FG:  1.002 – 1.012
