Added "ASBC Modification Using Mass"
In summary, the measurement of titratable acidity is a technique to quantify the total acid level of a beer. A major assumption was made: all the acid in the liquid was lactic acid. Two beers could have the same TA measurement, but have differing levels of palatable acidity, due to the acid makeup of the beer.
===ASBC Modification Using Mass===
The ASBC method requires both an accurate measurement for both beer volume and density. Depending on the quality of lab equipment available, these measurements can have variable error bars. In general, more accurate mass scales are more affordable than similarly accurate volume or density instruments; therefore, only using the beer and acid mass will lead to a more consistent measurement.
For a numerical example, assume 15mL beer, 5mL 0.1M NaOH:
