📢 What does copper sulfate do to wine?

An aqueous copper sulfate solution is typically used as a source of copper ions – these copper ions react with the sulfide ions in the wine to form insoluble copper sulfide, which is then removed by settling or filtration. This is a very effective way of removing the stench caused by sulfide ions from the wine.

📢 What happens when you add sugar to wine?

Yeast converts sugar to alcohol, and the amount of residual sugar left in the wine after fermentation determines how sweet or dry the finished wine is… Adding sugar to finished wine gives you more control over the final sweetness of the wine and also can correct weak flavor caused by poor quality wine ingredients.

Most of the time copper is added to the wine in the form of Copper Sulfate s(CuSO 4 •5 H 2 O), also known as Copper Sulfate solution. To avoid over adjustment, copper lab trial should be performed. Volume of wine, must, juice:

Copper fining of wine has been employed for many years as a way to remove sulfides from wine. An aqueous copper sulfate solution is typically used as a source of copper ions – these copper ions react with the sulfide ions in the wine to form insoluble copper sulfide, which is then removed by settling or filtration.

Copper is added to wine in the form of Copper Sulfate pentahydrate (CuSO 4 • 5H 2 O), a blue crystalline powder. The active ingredient in Copper Sulfate is the copper ion. The addition calculations on this site all assume you're using Copper Sulfate pentahydrate, as opposed to metallic copper or straight Copper Sulfate (the green stuff).

Copper sulfate is commonly added to wine to remove these unpleasant sulfidic wine aromas (often referred to as ‘reductive’ characters). It has been assumed that the copper ions bind to sulfur-containing compounds to form insoluble copper sulfides (Godden 2000), which are then removed by cold settling or filtration, although some recent work has highlighted the difficulty of this process (Clark et al. 2015). Often copper additions

Luckily, most of the copper present in juice is removed during fermentation via formation of sulfides and through binding to yeast and removal with the lees. However, steps should be taken to ensure optimal fermentation conditions to minimise the risk of a sluggish or stuck fermentation. This can be done by:

After a wine has been freshly fermented it goes through a period of stabilization. The chemicals added during this process are designed to pull unwanted characteristics out of the wine.
