Sterilizing Solution

Sterilizing solution has two uses: sterilizing equipment or sterilizing must. Each one requires a different strength. Each winemaker has his own view on what the proper strength solution to use.

Sterilizing solution for equipment

 Soak equipment at least five minutes in sterilizing solution.

Make a gallon of 1/2% sterilizing solution and keep it sealed in a jug so sulfur dioxide does not evaporate.
