...or Dominikaner Weingut Christoph von Nell-Breuning, to be precise.
This estate in the Ruwer village of Kasel was a completely new one to me. They own land in three different sites: the well-known Kaseler Nies’chen; Kaseler Kehrnagel; and the monopole vineyard Kaseler Dominikanerberg, which is comprised primarily of blue slate.
I had the opportunity to try two of von Nell-Breuning's Riesling's over the past week:
2012 Kaseler Nies’chen Riesling Spätlese Trocken
Lightly off-dry, medium-bodied, a bit tight, moderately acidic, mineral, with slightly muted lime and red fruit notes. This will benefit from a more few years.
1994 Kaseler Dominikanerberg Riesling Auslese
Pretty sure that I grabbed the last bottle of this. Nose of peaches, and caramel, with a bit of botrytis. Creamy, elegant, lightly sweet; old style Auslese; lightly slaty, with peach, honey, and vanilla flavors. Sharper slate on the finish. Showing really nicely.
While not at the qualitative level of Grünhaus or Karthäuserhof, both of these wines were very reasonably priced, selling for under $20 each.
Historically, von Nell-Breuning has also been a significant producer of sekt.
Currently, von Nell-Breuning' swines are being distributed in Massachusetts by Carolina Wines. I also found out that several years ago, the late Mosel Wine Merchant briefly imported them.
