I have also been thinking about comparing something. I usually drink non-alcoholic beers when I drive long distances.
But I tried Leffe Blonde 0.0 once, and it is the closest to the original. I also found the Kozel Dark acceptable. Of the industrial lagers, I can drink Heineken 0.0
But most of the other non-alcoholic ones, which is kind of a fashion now, I have to admit, suck.
Ah, and I forgot one other one, I was positively surprised by Brewdog's Punk IPA, but it doesn't taste the same.
