Ummm the belgian fruit beers start with beer.. Quite solid stuff alcohol-wise as well.. In which then fruit is soaked ( traditionally the sour cherries they call "krieken" ), originally to preserve it, the added taste to the beer is a bonus.
Later the added-flavour thing was done with fruit juice added to the still-quite-potent beer. Mort Subite ( sudden death ) and Verboden Vrucht ( forbidden fruit ) come to mind as well-known brands. Handle with care, they tend to trip up the unwary..
I don't know what to call the unholy concoction featured in the article, but beer it is not, nor would it be allowed to be called that in the civilised parts of the mainland. ( The uncivilised parts deal with this hipster shyte in a more time-honoured and more terminal way...)
