The level of volatile acids in wine and juice is an indicator of quality and is subjected to government regulation limits. Steam distillation is the preferred method for volatile acid determination. In this application note, learn how to perform the method by:
- Analysis of 2 unknown wine samples, 8 characteristic Swiss wine samples
- Protocol for sample preparation, steam distillation and titration
- Optimal parameters of steam distillation according to sample volume
- Calculations for determination of volatile acidity
Plus compare results to 31 laboratories with allowed accuracy limit of 0.05.
