Champagne Sherry

[Hopleaf]

I'm trying to determine if there is such a thing as Champagne Sherry. I'm editing a recipe that calls for "...champagne sherry or aged sherry vinegar." I'm thinking it's missing a comma, but I can't be sure that there champagne sherry isn't an actual ingredient. I've already checked several resources (Barron's Food Lovers Companion and Webster's New World Dictionary) but haven't found anything. Anyone?

A typo for champagne vinegar?

that's what I was thinking, but wanted to make sure.

Well... there are the Champagnes of Thierry Triolet, which do to some extent taste like a cross between champagne and sherry (in a good way).
