Tartaric Acid 100g (Food Grade)

Tartaric acid is the main acid found in grapes and the standard choice for adjusting the acidity and pH of homemade wine. This 100g pack suits smaller batches and the occasional winemaker who wants enough on hand for a few corrections without committing to bulk.

How much to add

Dosage: About 1g per litre lowers pH by roughly 0.1. Dissolve the powder in a little warm wine or water first, then stir it through the batch before fermentation. Always check with a pH meter or acid test kit rather than adding by eye, and adjust in small steps.

Making wine regularly? The 500g pack is better value per gram and saves reordering.

Frequently asked questions

Is this tartaric acid food grade?

Yes. This is food grade tartaric acid, additive code E334, the same acid naturally found in grapes. It is approved for food and beverage use in Australia and New Zealand.

Tartaric or citric acid for wine?

Tartaric for grape wine. It is stable, it is what grapes naturally contain, and it will not be broken down by bacteria during fermentation. Save citric acid for after fermentation is finished, and use it sparingly.
