Part 4. Chlorine contents of grapew ines.

Abstract

Chlorine in grape wines was determined by Volhard method. Results obtained were as follows:
1) Chlorine contents in 14 samples of wine showed the maximum of 42.522 mg/l, and the minimum of 12.765 mg/l. A tendency was found that the wine of high quality contained small amount of chlorine.
2) Wines made from hybrid variety of Koshu×Afs-Ali with white juice method and the ones made with skin must method showed no significant difference in their chlorine contents. Therefore, it was assumed that the chlorine is distributed uniformly in whole berry tissues.
3) Chlorine contents in wines from the grape of Seibel 13053 were varied with manurial conditions. The grape from the elements privation plots gave wines of higher chlorine contents and low quality.
