It is indeed a completely different scene, which is genuinely interested in variety.

It's a bit of a cliche but you really can split Europe into "beer country/wine country/spirits country". France, Italy, Spain and Germany west of the Rhine are wine country. Munich is clearly beer country. And Germany has focused on perfecting a very narrow set of light beers, if you want diversity of taste that's all in the wines. Similarly you're not going to get Parisians interested in beer diversity when they have French wine to argue about.

(It is possible that climate change will shift this; England is starting to produce a few pretty good wines)

Guinness 0% is fantastic. Unlike a lot of brewers the Guinness company were very keen to retain their standards rather than slop out an inferior product to tick a box.
