 Tannin VR Color

Specially formulated to stabilize wine coloring matter. TANNIN VR COLOR® has a high content of naturally active catechins (OxyProtect™ process) that allow the formation of chemically stable covalent bonds with anthocyanins for a superior color stabilization effect.

Tannin VR Color is used to improve the active tannin/anthocyanin ratio in such cases:

  • Grapes harvested at sub-optimal phenolic ripeness.
  • Grape Varietals with a naturally poor tannin/anthocyanin ratio.
  • Varietals that have color management problems (extraction/stabilization).

Dosage: 200 to 300 ppm - 1.6 to 2.4 lbs/1000 gal.
