Cependant, chez tous les grades, les teneurs en enzymes se situaient amplement à l'intérieur des limites jugées acceptables pour le malt canadien; les différences observées étaient sans doute liées à la teneur en eau au décuvage, significativement plus faible chez les deux grades supérieurs, puisque la teneur en protéines, facteur déterminant clé de la teneur en enzymes, ne différait pas significativement selon les grades.

Standard Select did show significantly higher diastatic power than both other grades and significantly higher α-amylase levels than the Special Select samples. Enzyme levels for all grades, though, were still well within the commercially acceptable range for Canadian malt. Differences in enzyme levels were most likely due to the significantly lower steep-out moistures for samples in the top two grades as protein levels, a key determinant of enzyme levels, were not significantly different among grades. Malt extract, a key component of malt quality, was very similar among the three grades.
