A friend of ours recently gave us a bottle of German corn liquor called "Berentzen Traditions Korn." How similar is this to American corn whiskey or bourbon "white dog?" Does anyone know? Tangentially, what do you think of American corn whiskey sold commercially here? We have disliked the American versions we have tried, but found this German liquor fairly light and refreshing in small quantities. Apparently, the Germans drink it neat and chilled, which is the only manner in which we have consumed it.
