JL Wolf - Vintages and Library wines

Hello Mr.Loosen,
Thank you for taking the time to answer our questions on this board.

My wife and I discovered our love for Riesling from your bottling, 2005 JL Wolf Forester Pechstein Spatlese. Thank you for making one of the best wines we have ever tasted.

My questions:
What was your favorite vintage of this bottling?
What are your thoughts on 2005 and 2010 vintage? 2010 is my wedding year. I would like to cellar a few cases for the next 2o years.
Have you stored any older vintages in your cellar?
