What is the Martinotti method?

What is the Martinotti winemaking method? The Martinotti winemaking Method, also known as the Charmat Method, was invented by Dr. Federico Marinotti at the end of the 19th century. The technique produces crisp Italian spumante wines and a floral and fruity aftertaste through a natural second fermentation in large sealed tanks (known as autoclaves). Prosecco winemaking history goes back to the Conegliano School of Wine-making, founded in 1763 by doctor Antonio Carpené, the first person to use a secondary fermentation process that gave Prosecco its famous sparkle.
