Wine with natural fermentation is the last born in Barichel house. While all the other wines are produced following the Charmat-Martinotti method, in this case the use of the autoclave has been abandoned to perform the second fermentation in the bottle, according to the rules of the classic method. Conegliano Valdobbiadene Prosecco DOCG "Natural Fermentation" by Barichel is a young and dynamic sparkling wine, well made.
