This Belgian Trappist brewery only makes one beer, but it is one of the most sort-after beers in the world. Brewed by monks within the walls of the monastry, Orval is an orange-hazed Belgian pale ale bottled conditioned with a special yeast called brettonomyces. When fresh the beer is sherberty sweet with a herbal hop profile and a hint of funky, farmyard-like brett. But after around six months the beer changes character completely, becoming dry and pithy almost like a Negroni, lifted by that lovely hop hit and remaining hint of sweetness. Truly one of the world's most enigmatic and brilliant breweries.
