Starting in the 1970s, particularly in the United States, enthusiastic homebrewers and small entrepreneurs began to push back against the uniform flavours of industrially produced lager. Pioneers such as Fritz Maytag, who took over the Anchor Brewing Company, and later founders of breweries such as Sierra Nevada, rediscovered traditional brewing methods and experimented with new hop varieties and flavour combinations. This movement spread worldwide and led to an explosion of beer styles, from hoppy IPAs to sour Belgian styles and experimental fruit beers. Today, craft beer culture forms a lively counterweight to the large commercial breweries and celebrates the diversity and craftsmanship of brewing.
