Monitoring changes in volatile acidity is important to detect the onset of spoilage.

This cash still complies with the American Society of Enologists-AOAC method to determine Acidity (Total Volatile) of wines. The steam chamber is heated by an 800 watt immersion coil that heats the distilled water to a boiling point in about 3 – 4 minutes. Two-way TEFLON stopcock fitted with funnel permits addition of sample into inner chamber or serves as an escape vent for CO2. The GRAHAM condenser has threaded fittings on the water feed and drain that makes the assembly and disassembly of the unit easier. Repairs and modifications possible for the cash still.
