Weirdly, making Rose Prosecco was illegal for the last few years. The “Prosecco” regulator thought it caused consumer confusion (and to be honest, we are easily confused). It is back now, since 2020, with a bang (or is that pop?).
Rose Champagne is one of the only wines in Europe that is made by blending red and white wines rather than by partial-skin-contact fermentation, like pretty much every other rose in the world. There you go!
