I just found a great deal on 2007 JJ Prum Wehlener Sonnenuhr Auslese at Costco. I had noticed it recently priced at $50, not a great price. Today I saw that they dropped the price to $30. I took the last 9 bottles from the Westlake Village location. Perhaps it is still available at a Costco near you.
I am unaffiliated with Costco, only a happy customer!
I remember paying that exact price for the 2001, an amazing vintage for German Rieslings as I am sure you are very aware ... at a local (Redmond, WA) wine shop known for its typically over-priced great wines. JJ Prum is always welcome in my home. I'll never forget the 1971s and 1959s I have enjoyed over the years.
