The variety is not that extensively grown here in Oz - in blends more than straight varietals - and I was surprised to learn that double the number of Greco De Tufo vines existed here last year than Malvasia vines !
I do remember some years ago a Riesling/Malvasia blend from the erstwhile Mornington Peninsula winery Ermes Estate. Chalmers blend Malvasia Istriana with Picolit to produce a Passito style dessert wine that is common in Italy.
Round and richly textured in taste with nutty, dry herb and peach characteristics backed up by good acid and a mineral backbone. Appealing grapefruit citrus and honey finish. Savoury with some phenolic grip to it. Light to medium-bodied wine with a viscous, almost oily quality. Shows loads of heart and character, an alluring complexity and basically, it's such great drinking. Age has certainly not wearied this Malvasia and let's hope there's more stand alone varietals like this one in future years. Excellent.
