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”.

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

• Kit volume: 80 ml
• Method: Two-reagent differential at 635 nm
• Limit of linearity: 180 ml/l
• Limit of detection: 2.0 mg/l (ppm)
• Calcium is present in wine at concentrations of 6 to 165 mg/L. Instability due to calcium tartrate appears at 4 to 7 months of fermentation.

Carbon dioxide is a natural gas produced during fermentation that is dissolved in wines. The addition of CO2 during preparation directly affects the aroma and taste of wine and can enhance freshness and acidity in the mouth, softening the sweetness. However, it can also intensify bitterness and astringency. Info + Purchase
