blanc de blancs traditionally means white wine from white

suppose all white wine is 'white of white' but on a wine label
it should but often doesn't, denote that it is a white made from
only white grapes. Champagne and other (white) fizzes are
commonly made from black grapes. Another thing, I *think/ just
about believe* that there are very few rules regarding use of
the term blanc de blancs: it's possible that a producer or
retailer could label a red wine like that without getting into
trouble.

I don't know if I really get you message. First, 99.9% of all
white wine is made from white grapes. There are well-known
exceptions: Champagne (except for those labelled "Blanc de blancs"
which are made from chardonnay only) and white zin the most
notable. Second: Most other fizzes worldwide are made from white
grapes. Third: The usage of "blanc de blancs" on the labels of
white wine (still or sparkling) is not restricted, as long as
there are no red grapes in the make-up. Fourth: "Blanc de blancs"
on the label of a red (or rosé) wine is ruled out, of course,
since it's misleading.
