So far, my favorite has been Guinness’ NA. It’s _almost_ imperceptible from the normal canned draught. My only real hangup with it is the extra plastic waste via the widget.
Likewise! I'm trying not to drink much anymore. But I always want something cold and fizzy. So it's a switch between refrigerated carafes of water, seltzer, and zero-alcohol beers. Although I feel incentivized not to have even the zero-alcohol beers since it's still 60 calories. While the seltzers I find are 0.
Any beer recommendations? I haven't tried much outside of the locally-supplied zero-alcohol Heineken and Corona.
The Bitburger NA with the blue branding is good. Don't be fooled if you don't like the normal Bitburger, imho their NA is much better :P OTOH, if you happen to like Bitburger, they also have a newer "dry NA" variant with green branding, that tastes much more like their alcoholic beer.
No idea about international availability, but at least a slight chance.
For wheat beer, the bigger German what beer breweries offer a NA variant these days, and those are quite good. I'm thinking of Erdinger and Paulaner, which are probably your best bet internationally. Don't tell anyone I know, but my secret recommendation however is Öttinger NA wheat beer. Those are cheap and taste very good (fellow Germans: If you don't believe me, do a blind tasting). But don't ever the mistake of buying or even drinking their normal Pilsner/Export beer - those taste like pi... ;-)
If you're ever in Germany, is "Mönchshof Radler Alkoholfrei". Radler is "shandy", a mixture of beer and lemonade. I've yet to meet anyone who likes beer but not this.
Where? In eastern US, Athletic Brewing makes really good hoppy ales. The ones from Brooklyn Brewery are good too, but a bit heavy for my taste.
In continental Europe, Germany has a large selection of lagers, good but not great. Clausthaler is an example. Also, I like the Czech beer Staropramen.
However most alcohol free beers don’t taste nice. Takes a bit of shopping around to find a brand that doesn’t taste like Ovomaltine.
