Wine Additives, Nutrients & Acids

Wine additives and nutrients help home winemakers manage fermentation, prepare fruit and stabilise finished wine. Different products perform different jobs, from supporting healthy yeast activity to improving fruit extraction and preparing wine for bottling.

Our Wine Additives, Nutrients & Acids range includes products for traditional wine, fruit wine and mead making.

Wine Nutrients for Healthy Fermentation

Healthy yeast needs suitable nutrition to ferment effectively. This becomes particularly important when the must provides limited natural yeast nutrients, such as when making mead.

Vintner’s Harvest Wine Nutrient 100g provides DAP, magnesium compounds, vitamins and trace minerals to support healthy yeast activity and complete fermentation.

Fruit Preparation and Pectinase

Fresh fruit naturally contains pectin, which can make juice extraction more difficult and may contribute to haze in finished wine.

Vintner’s Harvest Pectinase 75g breaks down pectin in crushed fruit. As a result, it can improve juice yield and flavour extraction while also helping produce clearer fruit wine.

Citric Acid for Winemaking Equipment

Vintner’s Harvest Citric Acid 100g is used as a final rinse after cleaning and sterilising winemaking equipment. It helps adjust the pH of the rinse water before equipment returns to use.

Stabilising Finished Wine

Once fermentation has finished, correct stabilisation can help prepare wine for sweetening and bottling.

Handcraft Supplies Campden Tablets x 100 contain sodium metabisulphite and can be used when treating fruit must or preserving finished wine and cider.

Meanwhile, Vintner’s Harvest Potassium Sorbate 50g – Wine Stabiliser helps prevent remaining yeast cells from reproducing. Campden Tablets and potassium sorbate can therefore work together when stabilising finished wine before sweetening or bottling.

Wine and Mead Making Supplies

Choosing the right additive depends on the stage of your winemaking process. Nutrients support fermentation, pectinase assists with fruit preparation, while Campden Tablets and potassium sorbate have important roles during treatment and stabilisation.
