Maceration is defined as the softening and breaking down of skin resulting from prolonged exposure to moisture. It was first described by Jean-Martin Charcot in 1877. [ 1 ] [ 2 ] Maceration is caused by excessive amounts of fluid remaining in contact with the skin or the surface of a wound for extended periods.
Maceration continues during the fermentation period, and can last well past the point when the yeast has converted all sugars into alcohol. The process itself is a slow one with compounds such as the anthocyanins needing to pass through the cell membrane of the skins to come into contact with the wine.
Pre-fermentation Maceration is generally performed at a controlled temperature to delay the onset of fermentation. This technique improves the extraction of varietal aromas and their precursors which are mainly located in the skin. Acidity decreases as does the ratio of Colloids (large pectin type molecules) and aging potential. To be ...
Treatment: The bumps go away on their own over several months. However, they are contagious, even to other parts of your own body, so Dr. Zeichner recommends getting professional treatment.

The press first draws the screw back into the container as the grapes to be loaded in. Then the screw moves forward horizontally acting more like a "battering ram" than an auger by intermittently pushing the cake in "impulses" against the far end of the press. While producing slightly less phenolic press fraction, the disadvantage of this press ...
