back when i worked for uncle dan, i did some staff education on the no alcohol peroni and heineken and most of the staff couldn't pick which was which. i know i could just taste a difference and that was if i really looked for it.
Maisels Weisse Alkoholfrei is the best 0-0.5% beer I've tried, and there was a month or so last year when I tried every one I could find. It had enough flavour that it tasted bloody good even without the alcohol contribution. Second best way Weihenstephaner Hefeweizen Alkoholfrei, daylight to everything else.
Back in the noughties in the UK Guinness put out a zero alc beer called "Kaliber". It wasn't bad and on holiday over there - I was supposed to be teetotal at the time, long story - I drank Kaliber at the holiday cottage.
Perfect excuse to slurp a Kaliber, walk over to the next village and sink a few pints of Theakstons or Black Sheep then back to the cottage for another Kaliber. Nobody would know the difference but SWMBO was puzzled that I seemed to be farting a lot.
