Found this from an old post on Catholic Beer Review. Thought you'd all appreciate. :)
Benedic, Domine, creaturam istam cerevisiae, quam ex adipe frumenti producere dignatus es: ut sit remedium salutare humano generi, et praesta per invocationem nominis tui sancti; ut, quicumque ex ea biberint, sanitatem corpus et animae tutelam percipiant. Per Christum Dominum nostrum.
Bless, O Lord, this creature beer, which thou hast deigned to produce from the fat of grain: that it may be a salutary remedy to the human race, and grant through the invocation of thy holy name; that, whoever shall drink it, may gain health in body and peace in soul. Through Christ our Lord.
