  • Technique: Gas Chromatography-Flame Ion Detection (GC-FID)
  • Price- NY*: $30; Price- non NY: $45

 Sensory Appraisal (distillates)

  • Purpose: Products will be assessed by a panel of three trained enologists to make preliminary judgments about sensory flaws.

  • Price- NY*: No charge; Price- non NY: $60


Acetic Acid (kombucha)

  • Purpose: Acetic acid is the most abundant volatile acid.
  •  Technique: HPLC/Enzymatic
    • Price: $90

Alcohol: Ethanol (kombucha)

  • Purpose: The amount of ethanol in kombucha must be less than 0.5% alochol by volume.
  • Technique: Gas Chromatography-Flame Ion Detection (GC-FID)
  • Price: $45

Sugars: Residual Sugar (kombucha)

  • Purpose: Quantification of the fermentable sugar (glucose and fructose).
  • Technique: HPLC/Enzymatic
  • Analysis Notes: Reported as a percentage, this analysis gives an indication of sweetness level. Yeast can metabolize both glucose and fructose.

* Analyses are offered at a discount to all New York bonded wineries, home winemakers, and craft distilleries because a portion of testing costs (50% for members; 25% for non-member NY wineries) are subsidized by the New York Wine and Grape Foundation (NYWGF). We are unable to offer this discount to wine distributors or out-of-state wineries because of the nature of NYWGF funding.
