Tehnologie aplicativă la prelucrarea strugurilor cu aciditatea excesivă

Abstract

Manufacture of the wines from raw materials with titratable high acidity has been optimized through deacidification with natural reagents, which does not alter considerably their nativity, namely with the ash obtained from vegetal raw material – by burning of annual vine canes or from the combustion of sunflower seed shells after oil exctraction. The invention relates to the wine industry, namely to a process for wine production provides for the chemical deacidification administration of a reagent locing used ash obtained by burning of annual wine alcools, which is introduced in a dose of at most 1,0 g/dm3. Partial chemical deacidification can be successfully used for triggering and carrying out a guaranteed malolactic fermentation, which is of particular interest in the production of red wines.
