It can be deduced that the date on the reverse label is designed to be read as a bottling date as well. The first batch, labeled as ''1er soutirage'' or "first racking' has a best by date on 10/12/2020 and a neck label of 2010-2011. This would mean that it was bottled on December 10, 2010. Oude Geuze Tilquin à L'Ancienne is released yearly in several batches/bottlings. The ''1er soutirage'' bottling was initially given to friends of Tilquin and was later available to purchase online for a short period of time.
All Oude Gueuze Tilquin à L'Ancienne bottles with a 2010-2011 neck label are a blend of one- and two-year old lambics, with the brewery having received their first batch of wort in 2009.
Oude Gueuze Tilquin à L'Ancienne is currently the only commercial gueuze on the market to contain lambic from Cantillon.
