We should probably agree that it depends on your choice of stylebook.
I think we can probably also agree that the gentleman who has spent many nights drinking wines in said province be given leeway to use the local vernacular.
That picture of Tanqueray has made me thirsty for gin.
I don't drink gin often, but when i do...........
Not meant to give Mr. Jonson a hard time - just chiming in per BA "standards" with a "wink" (maybe that was not obvious).
FYI - Been in the wine biz for 25 years. Sales, Educator, Wine Judge, etc. One of my pet peeves is misspellings per grape varietals, appellations, etc.
What particularly irks me is New World wineries theft/fraud and bastardizations of Old World nomenclature (i.e. California "Burgundy", "Champagne", etc.). I am sure Alsatians are likely as persnickety about what they are called or how they are referred to, as we are about how many refer to "OHIO" incorrectly.
