Many labels do not list "Sparkling Wine" since it is so declasse'.
For example, Ferrari "Champagne" just says "Brut" (CAP is specified different ways -- in this case just Methodo Classico)
I can show a lot of others. If it says "Brut" it means dry in the Champagne (or CAP) style/methode.
Likewise there can be sweet Bruts (e.g. N.V. Henri Abele Champagne Brut Cuvée Spéciale).
I was summarizing in that you won't see (or I never have seen) a Brut NOT done as sparkling.
I wanted to note that you can get really good "champagnes" NOT labeled "Champagne" but always labeled "Brut."
Gotcha. My wife is a true oenophile, and I thought I’d learned enough through osmosis, but I guess not.
