I have recently started trying out various alcohol free "beers". So far, the only ones that even remotely resemble something that tastes like beer are the ones from Waldhaus, Unertl, and maybe Becks. The Waldhaus alc. free are actually quite drinkable, and the Becks almost tastes better than the real thing (which isn't really saying much...). The rest have been anywhere from not-too-disapointing to just simply not worth consuming...
I am only going to list names and dates, the rest *mostly* isn't worth noting:
