Wine Analysis Home
- The Titratable acidity of a solution is an approximation of the solution's total acidity.
- The titratable acidity of a solution is measured by reacting the acids present with a base such as sodium hydroxide(NaOH) to a chosen end point, close to neutrality, as indicated by an acid sensitive colour indicator.(see equation and method)
- Titratable acidity, in regards to wine production, is given in units of g/L as per tartaric acid equivalents.
