From English ale to Czech lager, Belgian sour to American pale ale, German Berliner Weisse to Australian Adelaide sparkling ale, award-winning author Tim Hampson explores beers from four continents to choose his 50 favorite brews.

He discovers dark beers, light beers, sour beers, imperial stouts, beers flavored with honey, herbs and spices, and beers that have been matured in wooden barrels that once stored some of the world's best whiskies.

The world of beer is undergoing a revolution. More beers and more beer styles are being brewed than ever before in the history of the best long drink on the planet. So it was no easy choice.

What will make the top 50, and will your favorite brew be included?
