Cologne and Dusseldorf enjoy one of Europe's most entertaining rivalries, even if it doesn't get much airtime in the UK. These German cities are at daggers drawn over football, carnivals - and beer. Cologne has Kolsch; Dusseldorf Altbier. Both styles are brewed by Orbit, a thoroughly Euro-phile outfit. It's a laudable approach in a city swamped by hop-heavy pale ales, which is nonetheless beginning to appreciate Germany's magnificent contribution to the world of beer. On this occasion, I think Dusseldorf is the winner, with the nutty, bitter Neu the pick of Orbits brews. You may disagree, particularly if you're from Cologne.
