Since December 2008 Nokian Panimo rolled out a series of new beers. Non of their old beers remained. The name and appearence changed as well as the types. It seems like they got rid with the old Wackerbauer style and signature. Yes, Prof. Wackerbauers signatures which was on the old canes and bottles couldn't be found any more.
In 2008 I brought one of the bottles to one of the students at the VLB Berlin. They found it very funny to see their retired professors signature on a bottle of a brewery stating that this is good quality.
Btw, they also have a new website which you like to check out.
