Gotta say... Heineken Zero is much better than I expected it to be. I was expecting something more like lightly-sugared hop squeezings. It tastes like a slightly lighter version of Heineken Light. Which, while maybe not the best beer in the world, does at least taste like beer. It's good enough I can have one (or two, or a hundred - no alcohol) and not have to pretend I like it. I actually like it just fine. It's handy.
I suppose if you don't like Heineken at all, you will not be impressed. But rather like the stuff - all versions.
I just tried Clausthaler “Dry Hopped” non-alc. Actually somewhat OK.
The Guinness zero is strange. They managed to get many of the flavors of actual Guinness but not all of them. And what’s missing isn’t the relatively small (4.2%) amount of alcohol, it’s something bigger.
