Boon Oude Geuze VAT 31 is an exceptional, complex Belgian Lambic beer crafted by the master blenders at Brouwerij Boon in Lembeek, Belgium. At a robust 8.5% ABV, this specific release is a "Mono Blend," meaning it showcases the unique personality of a single historical oak barrel—Foeder No. 31, which was originally built between 1905 and 1908. The base Lambic was brewed on November 30, 2015, and allowed to age in this historic cask for four and a half years before being blended with just a touch of young Lambic to trigger secondary bottle fermentation. Packaged in a traditional 375ml corked-and-caged bottle, this cellared geuze pours with a fine, elegant carbonation and opens with a complex, cognac-like aroma. On the palate, it delivers a smooth yet deep profile marked by notes of apricot, walnut, and a prominent, clean oak character, making it a highly sought-after gem for beer connoisseurs and cellaring enthusiasts alike.
