Do you know Weißherbst? A Weißherbst is made from red grapes that are processed as if they were white grapes - as happens with many other Rosés as well. The special thing about a Weißherbst is that it must be from one and the same red grape variety. (Similar to a single malt whisky.) And it must be a quality wine. Maybe it is a special German thing. Have you ever tasted a Weißherbst?
