Context paragraphs:
Corsendonk: Corsendonk is a Belgian beer brand.  The brandname refers to the Priory of Corsendonk in Oud-Turnhout; which was in operation from 1398 to 1784, and was rebuilt in 1968 as a hotel complex by new owners Corsendonk Hotels.  In 1982, on the 125th anniversary of the Oud-Turnhout municipality, Jef Keersmaekers, grandson of Antonius Keersmaekers who had founded a brewery in 1906, was approached by the local tourist office to use the Corsendonk name for its abbey association, as an abbey beer marketing technique.  He launched "Pater Noster", now called "Corsendonk Pater" (or ""Abbey Brown Ale"" when marketed in America), and "Agnus Dei", now called "Corsendonk Agnus" (or ""Abbey Pale Ale"" when marketed in America).  As the family brewery had closed down in 1953, the beers were contracted out to other breweries, including Brasserie Du Bocq, who now brew all the brands.  Other brands include "Corsendonk Blond", "Corsendonk Bruin" and "Corsendonk Christmas Ale".

Duchesse de Bourgogne (beer): Duchesse de Bourgogne (] ) is a Flanders red ale-style beer produced by Brouwerij Verhaeghe in Vichte, Belgium.

The name of the beer is meant to honour Duchess Mary of Burgundy, the only daughter of Charles the Bold.  She was born in Brussels in 1457, and died in a horse riding accident.  Like all Flemish red ales, Duchesse de Bourgogne has a characteristically sour, fruity flavour similar to that of lambic beers.

Gueuze: Gueuze (or Geuze) is a type of lambic, a Belgian beer.  It is made by blending young (1-year-old) and old (2- to 3-year-old) lambics, which is bottled for a second fermentation.  Because the young lambics are not fully fermented, the blended beer contains fermentable sugars, which allow a second fermentation to occur.  Lambic that undergoes a second fermentation in the presence of sour cherries before bottling results in kriek lambic, a beer closely related to gueuze.
