Large wineries owned by immensely land-rich historic trusts are a typical feature of the franconian wine scene, especially in Würzburg. As these go back to charitable - or not so charitable - institutions founded in the late middle ages or the 16th century, they have had some time to accumulate land, assets and reputation. By running wineries alongside hospitals (that's where the "spital"-part comes from), nursing homes and real estate operations, they preserve a forgotten model of business, social services and agriculture whose usefulness must have seemd self-evident to citizens in many premodern cities.
To the Wine Rambler, Silvaner remains one of the undervalued German grape varietals, particularly as seen from my London perspective. I don't think I have ever come across a Silvaner in a London restaurant or wine shop. This may not mean very much of course as Londoners would also find it difficult to get German Pinot Blanc or Pinot Gris, for instance, but I recently learned that even more knowledgeable wine people can confuse Silvaner with the (Austrian) Grüner Veltliner (Silvaner is sometimes called 'Grüner Silvaner'). Is this Silvaner from the Juliusspital winery going to change all that?
