What is the name of the technique where Prosecco producers intentionally leave lees in the bottle, resulting in sediment?

Answer

*col fondo*

While the standard Charmat Method involves filtration to remove spent yeast cells (lees), a small segment of dedicated Prosecco producers utilizes the *col fondo* technique. This approach represents a deliberate return to older traditions where the lees are intentionally retained within the bottle when the wine is packaged. The retention of these spent yeast cells directly leads to the presence of sediment in the final product. Wines produced this way are described as offering a 'wilder' profile and increased texture, appealing to consumers seeking the complexity and richer mouthfeel traditionally associated with bottle-aged sparkling wines, but originating from an Italian base.
