 Perhaps the closest thing to passum is Moscato Passito di Pantelleria from Zibibbo, a variety of the ancient muscat grape, produced on Pantelleria, an island in the Strait of Sicily (50 miles from Tunisia) opposite to where Carthage used to be.Barossa Valley producer, Turkey Flat Vineyards has been experimenting with this style very successfully since 2002 with their 100% Marsanne aptly named 'The Last Straw'.Air-dried on racks for approximately 6 weeks it is fermented in new oak & now bottle post-fermentation to retain freshness.
