I agree with many of the other posters about the Berry Weiss being over the top. To me, it's like you made a shandy with beer and kool-aid. It's too sweet and too fruity.
IIRC the old advertising literature for that beer said it was blackberries, raspberries, and loganberries...I remember wondering what the heck a loganberry was. I'd go for a mixed berry blend and considering the amount that the berries overwhelm the beer, any dark berries would get you close.
Leinie's was the first craft beer I started to drink, but they do a lot of their beers over the top - Berry weiss is too much berry, sunset wheat (which I'll drink gladly, but there are better wits) is too fruity, the maple bock is good for one beer, but it's too mapley, etc.

Yes, that *is* beer. Water, malt, hops, and yeast mean it's beer. Go ahead and try a glass...
