As the name suggests, the Geuze Discovery Box is a box that lets you discover several new geuze beers. The box contains four new Oude Geuze Boon ‘VAT’ beers, each matured in its own particular oak barrel at the Boon Brewery reserve. In the cellars of Boon Brewery today, there are 158 giant oak barrels known as “foeders”, each containing up to 27,000 liters of lambic beer. Visitors to the Brewery sometimes ask whether they can taste the beer in the barrels and whether the beer from a particular barrel can be bought in shops. In the past, this wasn’t possible because Oude Geuze Boon normally consists of a mixture of lambic from several different barrels. “But then we thought about it and, in 2013, we brought the very first Oude Geuze Boon VAT 44 to market,” explained Frank Boon, founder of the brewery. “This was a small production of Oude Geuze made up of 90% lambic from a single barrel, foeder number 44. The remaining 10% was a young lambic which contained the sugars for the bottle conditioning.” “The oak barrels in our brewery each have their own history and are characterised by unique microflora of wild yeast. The use of lambic from a particular oak barrel creates geuzes with very distinctive characteristics: vinous, whiskey-like, bone dry or very soft.
