"For this Oude Geuze, 2-year-old Lambic matured for 18 months on cognac casks. The previous cognac ageing leaves a refined impression of dried fruit, grape-like warmth and elegant oak, layered onto the vinous character of Lambic. The finish is dry, long and complex."

"Oude Geuze Oud Beersel – Reborn – Brewers Edition (75cl) is a unique anniversary blend celebrating 20 years since the reopening of Oud Beersel. This Brewers Edition was born from an exceptional international collaboration: brewers from Norway, Mexico, Romania, New Zealand, Poland, Australia, Luxembourg, Austria, and Chile travelled to Oud Beersel to taste and select lambics straight from the wooden barrels, and to craft one shared blend together.

Reborn is built around 4-year-old lambic from Demi-Muids (630 L) with a pronounced vanilla note, blended with younger lambic from Oud Beersel’s Oude Pijpen (650 L). The combination of barrel types, ages, and this collective selection results in an unusually elegant Oude Geuze—an international collaboration that showcases lambic tradition and craftsmanship to the world.

Participating breweries: Oud Beersel (Belgium) · Nøgne Ø (Norway) · Interstellar Brewery (Mexico) · One Two Brewery (Romania) · Garage Project (New Zealand) · PINTA (Poland) · Wildflower Brewing & Blending (Australia) · Totenhopfen Brauhaus (Luxembourg) · Hopfengrund (Austria) · Granizo (Chile) "

"This Oude Geuze starts with 2-year-old Lambic and then matured for 18 months on rum casks. The wood still carries traces of rum, bringing hints of molasses, cane sugar and soft vanilla that weave naturally into the Lambic profile. After bottle refermentation, the finish is long and elegant with a warm, gently spiced touch."

"This geuze is a tribute to the Pajottenland region and its rich heritage. This unique blend combines young and long-aged traditional lambic, brewed with premium barley and wheat harvested from the fields of the former Lords of Gaasbeek. For centuries, these fertile fields served as the granary that supplied the castle with its daily bread and beer.
This bottle of artisanal geuze is the result of more than five years of work. The oldest lambic was brewed in March 2021, and the bottle was bottled on October 3."

"The craft : In the autumn of 2024, we visited the Charente, the region of Cognac. There, we selected three different types of Cognac barrels: 30 year old barrels of 550 litres, 20 year old barrels of 450 litres, and young barriques of 220 litres. In these, we let a geuze blend mature for an extra season, until it became our beautiful Charent'euse.
The Experience : In the nose, Charent'euse reveals the unique character of cognac. The integrated wood tones combine vanilla with notes of matured eau de vie. The finish is long and silky soft, with a typical warm glow."

Season 2024-2025 Assemblage #27. Bottling date: 19/06/2024

"For this blend of Oude Geuze, we blended not less than three different barrels originating from eight brews, brewed by 3F (68%) and Lindemans (32%). About thirty-two percent of the blend was brewed in November 2019, rendering the wieghted average age on the moment of bottling to more than 29 months. While blending, we added a bit of honey from our Schaarbeekse orchard field bee residence."

Season 2025-2026 Assemblage #10.bottling date: 03/02/2026

"For this Oude Geuze, we blended lambic originating from three different barrels and nine different brews. Most of the lambics are our own, except for about 10% that was brewed by Lindemans. The blend consists of equal parts of young and two-year-old lambic and 10% of three-year-old lambic. This renders the weighted average age of this gueuze to more than 22 months on the moment of bottling"

Season 2022-2023. Assemblage #105 bottled on 19/03/2023. "For this Oude Geuze Cuvée Armand & Gaston, we blended six different barrels of lambics originating from eight different barrels. This geuze is blended with 53% one-year old and 47% three-year old lambik, rendering the weighted average age to almost 24 months upon bottling and 65 months upon its release. While bottling, we added some fresh lambik wort. The cereals were harvested with our cereal collective, a network of local organic farmers. One third of those cereals are heirloom varieties of wheat and barley."

Season 2024-2025 Assemblage #12. Bottled on 04/03/2025. "For this Zenne y Frontera, we blended all of our Gutiérrez Colosía barrels. This family bodega at the port of Santa Maria in the province of Cádiz, provided us with some of the finest barrels, of which one was a very outspoken Manzanilla barrel. This blend consists of lambik aged on five distinct sherry barrels. We matured very old lambic for another thirteen months on these barrels. Consequently, the weighted average age of this blend is over 60 months."

Season 2024-2025. Bottled on 13//01/2026. "The third batch of Zenne d'Auge is a blend of six very old Calvados cask matured lambics. These Calvados casks were sourced with Domaine Familial Louis Dupont in Victot-Pontfol, in the heart of Normandy. The history of this renowned cidrerie and calvados house goes back for more than 150 years. They are renowned for their balanced ciders and characterful calvados range. And they harvest their own organic sour and bitter apples from their own orchards as well. All lambics originate from four different 3 Fonteinen brews and six different neutral barrels, before they were put on the Calvados casks for extended ageing. This Calvados barrel matured geuze is the testament of blending our traditions & crafts. "

Season 2025-2026 Assemblage #16.Assemblage. Bottle date 10/03/2026. "For this Oude Wintergeuze, we blended two small foudres of our ‘Longest Boil’, and some wort of the latest brew of the same base beer. This brown lambic started out as an experiment in 2018 and follows an original recipe from the 19th century. At the beginning of each season, we now boil some of the first lambic brews for 18+ hours in order to ‘start up’ the brewing installation. As the wort reduces, the density rises (and so will the alcohol content) and due to the Maillard reaction, the lambic obtains a dark caramel-alike texture and colour. The weighted average age of this blend upon bottling more than 36 months due to the extended barrel ageing. "
