AST

Contains potassium metabisulfite, ascorbic acid and hydrolyzable tannin in carefully balanced amounts to maximize antioxidant and antimicrobial action. When used on grapes, AST provides the antibacterial and antioxidizing protection delivered by sulfur dioxide, while limiting macerating action. It is suitable for the treatment of grapes intended for sparkling wine base, white grapes rich in phenolic substances and for grapes that have been machine harvested. When used in the treatment of must derived from grapes rich in aromatic precursors, it assists in the production of wines with intense varietal aromas. AST is very effective in preventing atypical ageing off-flavors.

  • Applications: anti-oxidant protection of grapes and juices; aromatic grapes; must for base wine for sparkling wines; prevention of atypical ageing
  • Dosage: 100-200 g/ton of grapes; 15-20 g/hL in juice; 10 g/hL of AST provide approx. 28 ppm SO2
