If Swabia were a nation, it would as of now be the world's only nation ruled by an environmentalist green prime minister. And it would have a national grape. And that grape's name would be Trollinger. Trollinger, known also as Vernatsch in the Alto Adige region of northern Italy, a grape that Jancis Robinson's authoritative Oxford Companion to Wine classifies as "distinctly ordinary". Not many outside of Württemberg deny that this is so.
