"Flint is our newest geuze inspired blend of wild ales. The beers that are used in this special blend where aged for 6 months up to 5 years in oak barrels. Peaches, straw, red wine barrel notes, some lemon funk with a hint of black pepper are present in the aroma. In taste you get pink grapefruit, white wine grapes, raw honey and some oak in the back with a earthy and somewhat leathery aftertaste. The mild acidity, tannins from the wood and a slightly bitterness from the aged hops, are complementing each other perfectly."

"Spróng is a blend of wild ales varying from 6 months up to 4 years, with Sicilian sage. This vintage we tried to enhance the herbal qualities of the sage together with a fresh, and vibrant but yet characterful blend of several oak puncheons (500 and 400 liters) and a rustic saison. The nose reveals herbal aromas of fresh sage, oak, bergamot zest, green jasmine tea, and even a subtle hint of mint. On the palate, the sage is well-integrated and complements the lemony, earthy, and funky notes from the beer. The acidity is balanced and not overpowering, which works well with the Spróng has a clean and refreshing aftertaste that invites another sip."

""The 2023 edition of this natural and sparkling sour cherry Lambic beer, born from the meeting of two glorious traditions, the Traditional Method for sparkling wines and spontaneous fermentation for Lambic beers. Oud Beersel cherry lambic is drawn in the bottle with the addition of the liqueur de tirage, which consists of sparkling wine yeast and sugar for secondary fermentation. The beer then ages for fourteen months in the bottle before being finished according to the "traditional method". This process allows the development of fine carbon dioxide which is trapped in the bottle and which makes the Lambic sparkling. The application of riddling and disgorging eliminates the yeasts present in the bottle. No added sugars by adding an expedition liqueur. The result is a BRUT and sparkling fruit lambic beer with an impressive palette of flavors."
