Chemetrics, 10-100 ppm range.

This is a ‘ripper’ test where the sulfite is titrated with an iodide-iodate titrant in acid solution using a starch indicator. The test is rapid, simple and the reagents are stable.

Accuracy is 2-10 ppm; because the test depends on recognizing subtle color differences, this test is more difficult and susceptible to error for red wine. Each kit contains 10 tests.

By Keith Weuste
The Titrettes work with red wine too. Have the titrette in front of a florescent light and watch the bubbles for the color change.
