  • Acetaldehyde is one of the components of the oxidative chain of alcoholic fermentation. Acetaldehyde is also formed in the wine aging process by ethanol oxidation. Acetaldehyde concentration is closely related to SO2 content. This combination is responsible for antioxidant activity. Info + Purchase
  • Acetic Acid (Liquid) Replaces 12810 Acetic acid is produced during both alcoholic and malolactic fermentations and helps enhance flavors and aromas. When the wine is aerated or remains in contact with air, acetic acid bacteria can multiply, leading to a problem known as “acetic spoilage”. The characteristic aroma of this spoilage is due to ethyl acetate. Info + Purchase
  • Acetic Acid (Liquid) Y200 / Y400 format. Replace 23810 Acetic acid is produced during both alcoholic and malolactic fermentations and helps enhance flavors and aromas. When the wine is aerated or remains in contact with air, acetic acid bacteria can multiply, leading to a problem known as “acetic spoilage”. The characteristic aroma of this spoilage is due to ethyl acetate. Info + Purchase

  • Low nitrogen levels have been related to slow fermentation or sulfide production. Conversely, high levels can lead to microbial instability and production of ethyl carbonate. Info + Purchase
    • Kit volume: 150 ml
    • Method: Two-reagent differential at 340 nm
    • Limit of linearity: 200 ml/l
    • Limit of detection: 3.0 mg/l (ppm)

  • Anthocyanins are the tinted pigments in grapes, with the word coming from the Greek root “antos” (flower) and “kyanos” (blue). These pigments are found in both the skin and the pulp. Info + Purchase
  • Ascorbic acid is a compound found in ripe grapes at very low levels compared with other acids (30-60 mg/L). It disappears rapidly when grapes are crushed, leading to early oxidation of must. Due to its reducing properties, ascorbic acid is used as an antioxidant. Info + Purchase
