Wachau is not only famous for its landscape and its wines. In areas where the soil is less favourable for wine apricots (in "Austrian German" called "Marillen", dont forget, the German spoken in Austria differs sometimes noticeably from the one spoken in Germany, this is even valid for the written language - you might get them even cheaper if you call them as a non-German foreigner by this name) are grown which have the fame to be the best all over Austria. In spring (April) these areas look fantastic with all the Marillen trees in full blossom. If you are here in the right time in summer (late July but it varies according to the weather, of course) you should buy and enjoy the Marillen, they are offered outside the gardens along the road. The fruits are only harvested when fully matured and therefore are not transported over longer distances than maybe to Vienna (other than those which are harvested almost green months earlier in Spain and Greece and transported even as far as to Finland where they arrive still hard an half green and almost tasteless, of course. The Marillen which are not sold at the spot are used to produce jam and to distill an excellent Schnaps. This is a sophisticated product and therefore quite expensive but has an incomparable smell and taste.
What to buy: The fruits you buy best from the gardens along the road during the harvest.
Marillenbrand from small and very small farmhouse distillers, sometimes even offered at this occasion along the road but do not buy without tasting first (the industrially produced stuff from producers like Bailoni or Spitz you usually get in Austrian supermarkets and in airport duty-free shops).
What to pay: The fruits cost according to the good or bad harvest - the better the harvest the cheaper the fruits.
The Schnaps (Marillenbrand) is not cheap, really good ones cost around 14 EUR and more for half a litre.
The most economic and charming way to purchase a larger quantity of wine in Austria is always right at the farmsteads of the producers. It is advisable to call ahead and the commented tasting is often a great experience itself.
What to buy: The most popular wine here is the "Gruener Veltliner" but also Riesling, Welschriesling (all white) and Zweigelt (red) are great here.
Lothar says that it might be the best price/quality relation for white wines all over Europe.
