Season 2021-2022. Assemblage #42. Bottled on 23/02/2022. "For this Langste Kook / Longest Boil - a special version of the Cuvée Armand & Gaston - we brewed a typical lambik wort, but with an extended boiling time. We usually boil for five hours - the highest in the lambik world and about tenfold of modern beer brewing. Now, we boiled a whopping eighteen hours. 18. Hours. After a full year of barrel fermentation and maturation, we blended with a young portion of lambik to assure continued bottle fermentation. With a weighted average age of the blend of almost twelve months upon bottling, this is a rather young geuze, but all lambikken were brewed with Pajottenland grains from our own Cereal Collective."

Season 2019-2020. Assemblage #59 bottled on 11/03/2020. "his Oude Geuze Cuvée Armand & Gaston Vintage was blended and bottled on Wednesday March 11th 2020. We let this bottle age for an additional four years before releasing it. It is a blend of one-, two- and three-year-old lambikken, originating from five different barrels and six different brews. The oldest lambik was brewed in April 2017. On the moment of the release, the weighted average age of this blend will have reached 67 months, or more than five and a half years. A true geuze, purely natural. Fully spontaneously fermented from brew to bottle, unfiltered, unpasteurised."
