petiotization

from The Century Dictionary.

• noun A process, much used in France (where it was devised by Pétiot, a Burgundian landowner) for producing a sort of secondary wine by adding to the marc, or residue from the expression of the juice of the grapes, a solution of sugar in water and submitting the mixture to fermentation.
