Grape Maturity

  • Botrytis and laccase activity
  • Yeast assimilable nitrogen
  • Alpha amino nitrogen, ammonia
  • Gluconic acid
  • Ochratoxin A in grapes and wine
  • Sugar analysis and hydrometry

Winechek can support your winemaking process from the vineyard with maturity analysis, nutritional levels and glucose/fructose measured separately.  Once the fermentation has commenced analysis is available to support yeast health during fermentation.
