Ascorbic Acid – 1kg Craft Bag

Ascorbic Acid (E300) – Brewing-Grade Antioxidant

Ascorbic Acid, also known as Vitamin C, is a powerful antioxidant widely used in brewing and beverage production to combat oxidation and preserve product quality. In beer, it acts as an oxygen scavenger—helping to protect delicate hop aromas, maintain bright colour, and prevent stale or “papery” flavours that develop during storage.

When used correctly, Ascorbic Acid enhances flavour stability and freshness without affecting taste or aroma, making it a valuable addition to both commercial and craft brewing operations.

Key Benefits

• Protects against oxidation – Reduces oxygen-related staling reactions in packaged beer.

• Improves shelf life – Maintains flavour, aroma, and clarity over time.

• Prevents off-flavours – Minimises “cardboard” or “papery” notes caused by oxidative stress.

• Enhances stability – Supports long-term product consistency and consumer satisfaction.

• Food-grade and versatile – Suitable for beer, cider, wine, soft drinks, and other beverages.

Application & Dosage

• Typical dosage: 2 – 5 g per hectolitre (g/hL) depending on oxygen exposure and beer style.

• Add as a fresh solution in deaerated water just before packaging or at the end of fermentation.

• Ensure proper mixing to achieve uniform distribution.

• Use in combination with other oxygen-control measures (CO₂ purging, low-O₂ packaging) for best results.
