For most people the concept of a "non alcohol" beer is anything under 0.5% ABV. Which I think is also the legal limit for a "NA" beer. After all, even kombucha has a slight bit of alcohol due to it being a fermented product. So most of the ones on the market do list a bit of alcohol in them. This is especially true for anything that is trying to be a NA "microbrew" style.NA - non-alcohol? Do these NA beers folks are talking about have alcohol in them? AB in the image above apparently does: "contains less that 0.5% alcohol". Is there a NA beer that has 0.0% alcohol. Asking for me.
The Budweiser Zero I posted about above is one of the few that lists "0%" ABV, as does Heineken NA. Though if one were militant about not having ANY alcohol, I might do a bit more research as I have no idea if "0%" actually means "under 0.04%" or something.
