Making alcohol is a sensitive procedure, and things can go wrong during the process resulting in a spoiled end product. That is why preservatives in wine are such an important component in ensuring the final product delivers the desired result. Preservatives in beer and wine help keep the fermentation process stable so that the flavour and aroma remain intact.

Our wide range of preservation ingredients is used in the beer brewing and wine fermentation processes. They are important for home brewing and microbreweries as they help preserve the quality of the batch and prevent spoilage. Among our products, we offer antioxidants such as Anoxyde and Suprarom and sulphates such as Sulfiredox, Oenosteryl 5 Effervescent, and Sulphur Rings. Please see our full range of homebrew preservatives or get in touch for any support.

Why Do We Use Preservatives inWine?

Preservatives are used in beer and wine for several reasons.

Firstly, while wine might taste great when freshly made, over time it spoils due to the effects of oxidation and bacteria.

Secondly, preservatives help protect the wine against these spoiling compounds, which otherwise could strongly degrade the flavour, aroma, and colour of the wine over time.

These preservatives include those normally used during the wine-making process, and those used for correcting any problems that occur during the process, such as offsetting poor-quality grapes.

Common Preservatives in Wine Making

  • Antioxidants–As the name implies, these preservatives are specifically designed to prevent the deterioration that occurs when the wine is exposed to oxygen. Sulphites are one of the most common antioxidants used in winemaking and can be added at any stage of the process.
  • Yeast –This type of preservative is used to improve the overall quality of wine batches, in particular their taste and aroma. Two types of yeast are used in winemaking: ambient yeast, which is naturally occurring, and cultured yeast which is added separately.
  • Acid control –The acidity of alcohol can affect the taste of wine as well as how long it will last. This preservative helps reduce the amount of acid in the wine, leading to a smoother and creamier taste overall.
  • Tannins –These preservatives are not essential to the wine-making process, but they do help balance the flavour and improve the texture. As such, many brewers use tannins to give their wine more character.
  • Fining agents –During fermentation, grape particles called colloids can affect the overall look and taste of the finished product. Fining agents help remove these particles, leaving you with crystal-clear wine.
  • Stabilisers –Wine fermentation can be an unstable process, and anything from temperature fluctuations to rough handling can ruin a brew. Stabilisers help protect the wine from any sudden changes that could potentially adversely affect them.
