Famous Austrian exports: Mozart, Arnold Schwarzenegger, singing families in matching paisley outfits, Brüno and Hitler. Not so famous Austrian exports: Grüner Veltliner. Which is a bloody shame, because if ever there was a food-friendly, not-too-alcoholic summer refresher to show Pinot Grigio how it should be done, then Grüner Veltliner (or ‘Groovey’ as it is sometimes known, but only by wine-tits) is it.
