Beer is bread. The calendar shows grapes, not grain. If grain were forbidden so would bread. If the fast were only about being miserable then I could accept that grapes = all alcohol. But it's not. The fast is about building us up spiritually. The reason we fast from certain foods - such as spam and big macs, but are allowed others like swordfish steaks and lobster - is to make us learn discipline and obey rules, even if we cannot understand them. I cannot believe that the Holy Church in its wisdom would ever take away something as life-affirming and love-kindling as beer.
