The French beer scene has improved over the last 10 years but yeah, it's still quite limited in terms of selection. When I was first visiting there really wasn't much at all outside of Belgian beers, though I've since had a few very good beers from Paris and other parts of the north of the country. Usually only finding them in larger markets, though, as you say.

The UK's beer scene is wildly different to the rest of Europe, and not something that we've managed to export very well. Hell, we could even export cask ale (rare outside of the UK) to Paris without it spoiling these days, yet nobody really does. Whether it's due to taste or the awkwardness of casks I don't know, but I do think it would meet with success in Paris if someone did it properly. Not all beer has to be refrigerated and fizzy. We have so many varieties that you just don't get with fizzy keg beer, and much of it notably weaker in alcohol content. Some examples:

Mild at ~2.5% (made from reusing the materials used to make Bitter), Session at ~3.5%, Bitter at ~4%, Best Bitter at ~5% etc. IPAs are the hot thing even over here now but we get notably more variations in those than most places too.

I'd be curious to know from anyone in Germany if they have equivalents to these sorts of categories, as what we get from Germany over here tends to all be about the same strength.

Due to ADHD meds I do now have to drink less, and the best non-alcoholic beer I've found so far is Guinness 0%. I'm not a massive Guinness drinker, it's alright but there are other stouts I prefer, but the 0% version is surprisingly close to "real" Guinness and has none of those sock-y flavours that most non-alcoholic beer has.
