When I was in practice, I could pretty reliably identify a sparkling wine
as a ("real") Champagne, and which district from within Champagne but not
better than that. I'm reasonably good a picking out a Penedès. I expect a
master Sommelier can do better and as part of the exam I believe they are
required to (among other things) identify with 75% accuracy six wines with
respect to grape varieties, country and district of origin, vintage and
quality level when presented blind.I can't do that. -- Charles
