Brussels, Belgium

Brussels is the gateway to Belgium's 1,500+ beer styles, with a UNESCO-recognized culture centered on lambic and gueuze from the Senne valley. Cantillon Brewery, producing wild-fermented lambics since 1900, offers year-round tours, and the city hosts over 200 beer cafés. This diversity is 40% broader than the average of the top 10, and its lambic brewing method is more labor-intensive than #4 Portland's craft ales, requiring a 3-year aging process.
