== Description ==
Oude Quetsche Tilquin à L'Ancienne ( véritable d'Alsace)is a lambic blended with a variety of plumsfrom Alsace. The plums are added in high concentration to one year old lambic for a period of four months (with the exception of the first test batch that aged for almost 6 months on fruit). The resulting fruit lambic is blended with additional two year old and three year old lambic to create a final fruit concentration of at least 250g/l. Oude Quetsche Tilquin à L'Ancienne is labeled as 6.4% ABV and is available in 375ml and 750ml bottles as well as on draught on occasion.
==Plum Varieties==
* 2011-2012 - Small test batch made with fresh prunes de Namur (Belgium), limited to 548 bottles and sold with a one 750ml bottle per person limit at the brewery only. The lambic spent almost 6 months on the fruit (fruit added 8/30/2011 and removed 2/23/2012).
* 2012-2013 - Made with fresh Quetsches véritable d'Alsace (France) because there were no prunes de Namur available due to cold weather. Released at Toer de Geuze 2013 after three months in the bottle.
* 2013-2014 (early season) - Made with fresh Quetsche véritable d'Alsace (France).
* 2013-2014 (late season) - Made with frozen Quetsche véritable d'Alsace (France). This is the first batch made with frozen fruit.
* 2014-2015 - This batch was split. Half of the batch was made with Prune de Namur, harvested by Jean Binamé in Bois-de-Villers, near Namur (Belgium). The remainder was made with Quetsche véritable d'Alsace (France). The ''Prunes de Namur'' version received a special labeling, pictured below.
Pierre Tilquin described the differences between the two plum varieties in a post on Facebook: "They are very close, but the Quetsche véritable d'Alsace is a little bit more sweet than the Prune de Namur, which is a little bit more sour. The Prune de Namur is also a little bit smaller than the Quetsche véritable d'Alsace".<ref name=TilquinPlumVarities> Facebook, [[media:TilquinPlumVarities-FB.png|Quetsche Tilquin - batches 2014-2015 in progress]], September 11, 2014</ref>
