MCC, Prosecco and sparkling wine – are they different?

• In champagnes and MCCs, the secondary fermentation – when the bubbles form – happens in the actual bottle, after the bubbly has been corked. • Proseccos undergo the secondary fermentation in steel vats and are bottled after that. • Sparkling wines are simply carbonated wines – the bubbles are artificially introduced rather than produced by the wine itself.
