I agree that the Lindemans Framboise is sweet and highly carbonated, but it is what it is and I for one think it is good. One must keep in mind the irreverent nature of the Belgian beers, "who cares what others think and who cares what style it "adheres" to". The previous refers of course to the Lambic "style" but I would say Lindemans Framboise is its own as should all beers in my opinion, unless of course you are a Trappist Monk and/or also possibly an Abbey.
Anyway, all this to say, Lindemanns Framboise is a damn fine "fruit lambic" in my opinion. Bottom line is... did you like it and would you drink it again?
Here is to throwing styles to the wind, slaint.
