Arguably brewing the most sought-after beers in the world, Cantillon brewery's Jean Van Roy has near god-like status in the world of beer. Brussel's Cantillon is a lambic brewery, where the beer is exposed to natural yeasts in the air and left to ferment in small oak barrels for several years. Beers of different vintages are then blended to balance the sweetness and sourness, before either being bottled or left to age over fruit, which is where Cantillon comes into its own. They use local grape skins, apricots, raspberries, cherries...anything they think will add to the beer. The results are some of the most delicious, complicated and rewarding beers in the world.
