The refinement is a fundamental stage in the wine evolution, as it allows the winemaker to highlight the qualities of his wine and to increase its stability over time. One of the most studied practices for the obtainment of full-bodied and harmonious wines with an intense and varietal aroma is the bâtonnage, an oenological technique with a long tradition in Burgundy, consisting in keeping the wine in contact with the less for several months and periodically re-suspending the lees by means of a gentle stirring. Inspired by this tradition a modern range of wine maturation and refining agents has been developed, named Bâtonnage Plus, which make the cell’s noble constituents immediately available in the form of mannoproteins-rich yeast hulls.
