Here MTF member Andy Carter presents an alternative calculation for measuring titratable acidity. The ASBC method requires both an accurate measurement of 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. Additionally, small gravity differences don't have a large impact when using the ASBC calculation. The following calculation for TA does not use specific gravity.
