Bless, + O Lord, this creature, ale which by thy power has been produced from kernels of grain. May it be a healthful beverage to mankind, and grant that through the invoking of thy holy name all who drink thereof may find it a help in body and protection in soul. Through Christ our Lord. Amen. (English translation by Rev. Weller)
Of course, this should only be used in moderation.
