1. A process for production of an alcohol product comprising the sequential steps of:
(a) holding a slurry comprising water and granular starch in the presence of an acid alpha-amylase and a glucoamylase at a temperature of 0° C. to 20° C. below the initial gelatinization temperature of the granular starch for a period between 5 minutes and 12 hours, and (b) fermenting the slurry in the presence of an acid alpha-amylase, a glucoamylase and a yeast at a temperature between 10° C. and 35° C. to produce the alcohol product, wherein step (a) and/or step (b) is performed in the presence of a phytase.
