Westhofen is Kirchspiel, Martin?
from UK-Forum;
it is from 40 years old vines of MORSTEIN.
and is not GG.
The GG Morstein is from 60 years old vines.
hi Martin
Interesting ranking. Years since i tried a Gunderloch, but it was fine.
Was your own ranking similar to the overall?
Claus,
Gunderloch was the clear winner for ALL.
The ranking is also MY ranking more or less. But you wouldn´t be surprised when I tell you that I saw Keller Morstein and Wittmann Morstein&Brunnenhäuschen much better. 
See you soon,
Martin
Fwiw, I have Rothenberg '13 GG on prearrival.
PM with inquiries.
