SO2 and acidity testing
Sulphur dioxide (SO2) is added to most wines and ciders to prevent spoilage
and extend keeping properties. Where sulphur dioxide is used its level
must be monitored to ensure both, that there is sufficient for it to
be effective and that maximum permitted SO2 levels are not exceeded.
Acid levels will affect the palatability and keeping qualities of wines
and ciders and will influence the amount of SO2 required.
Dr. Nilles kits
These are convenient portable kits suitable for carrying out tests on site
in the winery or cider barn. The reagents have an active life of at least
one year and the kits are very easy to use. This system is used by many
smaller vineyards and cider producers.
Sulfoquick Test. A complete test kit in
a strong carrying box for determination of free and total SO2. Sufficient
reagents for up to 200 tests of white wine or cider containing an average
of 50 mg/l.
Aciquick Test. For determination of total acid in wine, apple juice or
cider, packed in carrying box.
Titrofix kit.
This is a fast and efficient system mounted on a portable stand. Suitable
for use in a laboratory or on any table or shelf. This system is suitable for
winemakers or cidermakers who carry out frequent, multiple tests for SO2 and
acidity and require a high degree of accuracy. The test solutions have a shelf
life of around six months. This method is used by many of the larger English
