Titratable Acidity Analysis
Measurement of total or titratable acidity.Total/Titratable Acidity (TA) measures acidity by titrating a sample with a standardized base to a pH end point. TA is expressed as g/L acid equivalents or as a % acid equivalent and should not be confused with expression of hydrogen ion concentration by pH. TA is reported in applicable acid equivalents - malic acid for cider, citric acid for seltzer, lactic acid for sours, or acetic acid equivalents for kombucha.
TA affects taste and positively correlates to the perception of acidity, snappiness, sourness, tartness, etc. in a wide range of beverages including wine, sour beer, cider, seltzer, kombucha, and sake. This analysis provides an evaluation of titratable acidity for a cider, seltzer, kombucha or sour beer.
