Frequently asked questions

How to add the acid?
The acid is dissolved in a small amount of wine and added during racking or stirring; then the acidity is measured again.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
