For stereotypical American or Japanese tourists who also love wine, a visit to Schlossgut Diel has to equal the feeling of a child realising it has been locked in an ice cream parlour for lunch break. After all we are not only talking about one of Germany's top wine estates, we are also talking about a "castle winery", as that is what "Schlossgut" translates to. Castle Layen, where the Diel family has been based since the Napoleonic wars, was built in the 11th century. The wines in the cellar are not quite as old, but rumour has it some go back to the early 20th century, so the both lovers of medieval towers and old wine should be very happy there.
Sadly, I have yet to visit Schlossgut Diel (preferably leading a raiding party), but at least I managed to get my hands on a few bottles of their Riesling - this Kabinett Riesling from the "gold hole" vineyard being one of them.
