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 18/19 Assemblage #14 bottled on 13/12/18. Blend made with 100% lambic brewed by 3 Fonteinen orignating from 6 different barrels and from 9 brews. This blend is made of 60% young lambic and 40% semi-old and old lambic.

Season 2019-2020. Assemblage #25 bottled on 16/01/20. "This specific Cuvée Armand & Gaston has been blended with lambikken from seven different barrels and foeders and eight different brews. The oldest lambik was brewed in the first days of 2017, which is more than four and a half years prior to the release. We let this bottle condition for an extended time in our own cellars, and we will tuck away part of this blend for extended ageing in a beautiful, but undisclosed farm cellar somewhere in the Pajottenland."

Season 2020-2021. Assemblage #17 bottled on 20/01/2021. "This Cuvée Armand & Gaston has been blended with lambikken from four different barrels and originating from four different brews. Twenty percent of the cereals that we used for brewing the young lambik, were sourced in Brabant through our own farmers’ network. The old lambik that we used — brewed in the first days of 2018 — comes from two small 400-litre barrels that we found to be gently oxidative. The weighted average age of this blend upon bottling was eighteen months.."

Season 2020-2021. Assemblage #49 bottled on 27/04/2021. "For this specific Cuvée Armand & Gaston, we blended lambikken from three different barrels and five different brews. Upon bottling, the average age was about twenty months. A quarter of the lambikken used were brewed with heirloom Pajot grown cereals, from our own farmers’ cereal collective. The characteristics of this geuze make it an excellent geuze for extended ageing."

Season 2020-2021 Assemblage #43. Bottled on 20/04/2021. "In the spring of 2020, we bottled a Golden Blend (season 19|20 No. 40), containing lambikken from four different barrels and six different brews with three different breweries. Fifteen months of cellar conditioning and ageing later, this geuze blend appeared not to have carbonated. A part of the bottles was therefore opened again and was re-blended with both two potent jonge lambikken and 50-month oude lambikken - all 3 Fonteinen - to give the Golden Blend a second push to bottle carbonation and additional depth. This way, the weighted average age of this blend currently is at more than 36 months, with the oude lambik being brewed at the beginning of 2016."

Season 2021-2022 Assemblage #125. Bottled on 06/10/2022 "For this Oude Geuze, we blended six different lambikken originating from five different barrels. The lambikken used were one-, two-, three- and four-year old. This renders the weighted average age up to more than twenty-six months.

Bottled on 03/05/2022 "For this particular blend of Oude Geuze, we blended lambikken originating from six different barrels and ten different brews, brewed by three different brewers. We put a large part of lambikken of at least 24 months old (44%) and of at least 36 months old (36%). This way, the weighted average age of this blend upon bottling is more than 29 months. Of the lambikken brewed by 3 Fonteinen, more than half of the cereals used was sourced from our own Cereal Collective in and around Pajottenland."

Season 2021-2022 Assemblage #75. Bottled on 24/05/2022 "This particular blend of Oude Geuze consists of nine different brews originating from nine different barrels.

"For this Oude Geuze, we blended lambikken from three different barrels and six different brews, brewed by both Brouwerij Lindemans (38%) and ourselves (62%). More than two thirds of the lambikken were two-year and three-year lambikken, rendering the weighted average age of the blend upon bottling to moren than 24 months. All cereals used with the 3 Fonteinen brews were sourced in our own Cereal Collective."

Season 2021-2022 Assemblage #94. Bottled on 26/07/2022 "For this Oude Geuze, we selected lambikken from four ex-sherry barrels - three Oloroso and one Palo Cortado - with highly peated characteristics, and blanded these with a more mellow lambic to balance it all out. Consequently, we used lambikken from five different brews and six different barrels, spread over young, quite a lot of three-year old and four-year old lambikken. This way, the weighted average age is more than 35 months."

"This specific Oude Geuze Golden Blend only features one-and-a-half-year old and four-year old lambikken, but with the latter at 33% instead of the usual 25%. The oldest lambik was brewed on the 24th of January 2017 (so almost 50 months old). This way, the weighted average age of the blend amounts up to a tad more than 27 months. While blending, we added some honey from our own bee hives in Lot. The lambikken originate from three different brews and two different barrels."

Season 2020-2021. Assemblage n°41. Bottled on 07/04/2021. "This Platinum Blend is a blend of both jonge lambikken, two-year and four-year oude lambikken, originating from eight different brews and four different barrels. One fifth of the blend consists of lambikken brewed with our own sourced heirloom cereals from different spots in Brabant. The weighted average age of this blend is about 25 months, and the oldest lambik was brewed beginning of 2017.

Season 2021-2022. Assemblage n°59. Bottled on 08/04/2022. "For this particular Platinum Blend, we blended lambikken originating from five different barrels and eight different brews. This blend is a beast; we used almost 45% of four-year-old lambik (all brewed in April 2018) and an equal amount of two-year-old lambik. the This way, the weighted average age of this very Oude Geuze is more than 33 months upon bottling. Of all cereals used in these brews, almost 45% were sourced from our own cereal circle in Pajottenland."

Season 2020-2021. Assemblage n°40. Bottled on 01/04/2021.

We added some local honey from our own beehives to the blend. 100% 3 Fonteinen brewed lambik."

Season 2022-2023. Bottled on 24/12/2022. "This Zenne y Frontera is a very small bottling of a four-year old lambik that has aged for more than two-and-a-half-years on two Oloroso sherry barrels. The weighted average age of this Zenne y Frontera is therefor more than 45 months; the historical weighted average of geuze blends. The long ageing on the sherry barrels also results in a higher alcohol volume. This is indeed a bottle to be shared on special occasions. Bottle count: 770. 100% 3 Fonteinen."

"Our Cuvée Heritage Gueuze is a blend of the finest barrels of lambic and bears the label of the old brewery. They have a beautiful aging potential."

"This Gueuze is a traditional blend of young and old lambics.Just as a young larva develops for years within oak wood to eventually emerge as a beautiful beetle, this lambic undergoes a prolonged aging process in oak barrels to be enjoyed as Gueuze. Fermented, aged, and bottled on the farm."

"Boon Geuze Mariage Parfait has an alcohol content of 8%. It consists of 95% mild lambic, aged at least three years and specially reserved for this purpose, and 5% young lambic. The latter provides the fermentable sugars and wild yeasts. After mixing in a vessel of 25,000 litres, the wort (unfermented mixture) is filtered and chilled. If we are bottling, we bring it back to fermentation temperature. The bottles are placed in a climate-controlled space for the secondary fermentation. This is followed by maturing at low temperature for at least 6 months. Want to know the bottling date? Simply subtract 20 years from the “best before” date!
The soft, mildly sour berry taste, harmonises with the oak barrels’ aromas in which Geuze Mariage Parfait has ripen. The body speaks of vanilla followed by a bitter aftertaste of cloves that becomes increasingly intense. Sublime."

"Oude Geuze Boon Black Label Edition N°7 brings us back the typical long, dry aftertaste, yet very full-bodied taste that we are used to from Boon Black Label. With a very fresh citrus note and pleasant sparkle you can enjoy the Boon Black Label N° 7 as an elegant, easily drinkable tender Oude Geuze. This Edition N°7 was bottled on June 8, 2021. The blend is a mixture of lambic matured in oak barrels for one, two and three years. The Oude Geuze Boon Black Label Edition N °7 is a perfect aperitif beer. It is certainly also an ideal gueuze to enjoy with patience. It goes perfectly with fish dishes, such as combinations with oysters, salmon or mussels."
