Description

Used to determine the Total Acidity in a wine, the CellarScience Acid Test Kit is an invaluable tool for any home winemaker. Total Acidity measurements are important to winemaking because the correct amount of acidity is key to maintaining a wine which is balanced in flavor and stable for ageing.

Kit Contents:

  • Large Reaction Vial
  • 10mL Syringe
  • 4oz of Sodium Hydroxide Reagent
  • Phenolphthalein Indicator in 1oz Dropper Jar

Reagent Stability Information:

  • Sodium Hydroxide Solution - 0.1 Normal (2 year shelf life cool & closed, 3 month shelf life cool and opened)
  • Phenolphthalein Indicator - 1.0% (5 year + Shelf life)

Reasonably accurate
The test kit is much more accurate than the colorimetric test paper type kits. The syringe used to measure wine volume and volume of sodium hydroxide titrant is not particularly accurate. A much higher degree of accuracy is possible if a pipet is used to measure wine volume and a buret is used to measure the volume of sodium hydroxide required to neutralize the acid. The phenolphthalein indicator works well for white wine but the endpoint (color change) is not distinct in red wine. I recommend using a pH meter and neutralizing to pH 8.2 rather than using an indicator. The sodium hydoxide solution should not be left open any longer than required. Carbon dioxide in the air reacts with sodium hydroxide, reducing the effective NaOH concentration which would result in a higher acidity value than the wine actually has.

TA kit
This kit is a step above most of the others. Easier to read color change in large container because the lid allows quick mixing while waiting to see the change. Large enough for inserting probe from pH meter which takes the guess work out of finding the endpoint.

Manual TA test kit
It works much better than the Vinmetrica SC-300, at least I can get a more accurate reading as to the acid value.
