Joenos Ascorbic Acid (Vitamin C), 10 g Powder as Antioxidant

Ascorbic acid, better known as vitamin C, serves as an antioxidant in winemaking. It captures oxygen before it attacks color and aroma, and is therefore often used in oxygen-sensitive steps such as bottling.

The powder can be weighed out precisely and dissolves easily. The 10 g pack suits the small quantities in which ascorbic acid is usually used. Dose according to the package instructions and use the agent in a targeted way rather than generously. Keep in mind that ascorbic acid can complement sulfiting but does not replace it.

• Contents: 10 g ascorbic acid (vitamin C) as powder
• Effect: antioxidant protection for wine and must

Manufacturer's information:

• Dosage: approx. 5-10 g per 50 liters, maximum 25 g/hl
• Before adding, set the free SO₂ to 40–50 mg/l; afterwards, ascorbic acid makes the iodine test show more free SO₂ than there is, so later measurements are only possible in a laboratory
• Copper content maximum 0.25 mg/l
• According to the manufacturer, may reduce the risk of UTA (untypical ageing note); use only together with sulphur and add only once the free SO₂ has been set – ascorbic acid does not replace sulphur
