Ah, if only! I've only been able to make Eiswein once, when I lived in the Snowies, from a Chardonnay grape vine. It was wonderful. Haven't been able to afford to buy the stuff for years.
These grapes here are mostly a very old German sultana vine, an ancient pre-phylloxera Shiraz grape which I grew from a cutting from a friend's vineyard, and a delicious tiny black grape of which I have never been able to find out the name. If indeed it has one. I grew it from a piece I salvaged from a vine that was growing on the fence of an early-settler house that was being demolished at Mount Barker, and have never seen a vine quite like it. It's closest to a Zante currant, but not the same - the fruit is a little smaller and has a much stronger flavour. It dries beautifully to tiny sweet currants, is delicious eaten fresh and makes a good dessert wine. I'm trying to propagate it and spread it about.
I have other vines, but none that fruited this year.
