I can’t remember the last time I saw Wiedemann’s in a store.
But I am fairly sure it is still around.
Like a lot of the regional brews, the original died out, then some craft guys bought the rights and started a craft brewery, claiming they have the “original recipe.”

I haven’t had any Wiedemann, but after a Cubs/Reds game in Cincy a month ago, we went to a bar and they were selling Hudepohl. Same thing.
