The world’s first truly golden lager, the "original pilsner" was first brewed in the Czech town of Pilsen back in 1842, by a bad tempered Bavarian called Josef Groll, using local Saaz hops and moist Moravian malt. Still brewed on the new site and matured deep beneath the brewery in cold cellars for more than a month, it is best enjoyed when drawn, daisy fresh and hazy, straight from the brewery tap. Called Kvasnicovy, this version is unfiltered, unpasteurised and with further yeast added after fermentation. What proper pilsner tastes like – and a million miles away from the pale imitations that purport to be "pilsner". £1.99 for 500ml, waitrose.com
