Federweißer is the German name for a sparkling must1 from the first harvested white grapes - often those grapes that lack the quality to making a good wine. It is also known as Sauser or, in Austria, Sturm (tempest2), and is usually available from the beginning of September until the end of October, depending on in which region the grapes are grown.
