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!

Oude Geuze Boon is a monument of taste with an alcohol content of 7%. It’s a magnificent blend of 90% mild 18 month-old lambic, 5% strong 3 year-old beer and 5% very young lambic, which provides fermentable sugars and wild yeasts. All our beers are aged in oak casks, mixed in a vessel of 25,000 litres and chilled. Before bottling, we bring the mix to fermentation temperature. The bottles are then placed in an air-conditioned room, which leads to a secondary fermentation in the bottle. This is when the lambic becomes gueuze. After several months of aging in the bottle, the gueuze develops its delicate flavour.
