WTB old(er) reisling

I’m interested in acquiring older rieslings. I’ve yet to experience characteristic tertiary aromas and flavors (petrol, rubber, lots of slate etc) of a mature riesling and am hoping for good examples. Producer and sweetness levels/ style are less important to me than an overall mature riesling characteristics, though I do love young JJ Prum wines. Thanks ahead of time!

Charles - how old were you looking for? 70’s, 80’s, 90’s, early 2000’s?

looks like Chris is selling some.

I’ve got some I can spare, '50s-80s, that won’t break the bank.
Email me auntboy@mac.com if you’re interested:)
