The Sub‐Committee was unable to recommend the determination of wort fermentability as an alternative to the determination of diastatic activity in the evaluation of malts. Potassium ferricyanide solution is recommended as an alternative to Fehling's solution in the determination of the diastatic power of malt because the titration is simpler and the reproducibility of the determination is less dependent on the volume of cold water extract taken for diastasis.
