1. A process for producing a fermentation product from starch-containing material comprising:
i) liquefying the starch-containing material at a temperature above the initial gelatinization temperature using:
an alpha-amylase; and
a protease having at least 95% sequence identity to the amino acid sequence of SEQ ID NO: 13;
ii) saccharifying the liquefied material obtained in step i) using a glucoamylase; and
iii) fermenting the saccharified material obtained in step (ii) using a fermenting organism.
