Have pope Vincent III ban coffee instead of accepting it. Coffee was believed by some Christians to be the devil's drink. Pope Vincent III heard this and decided to taste it before he banished it. He enjoyed it so much he baptized it, saying "coffee is so delicious it would be a pity to let the infidels have exclusive use of it." Have him like the taste of coffee a little less and there is your excuse for no coffee. Now having mate replace tea in the western world is the problem. And don't think it isn't possible, until Vatican II all Catholics did not eat meat on any friday, and a lot didn't eat it on wensdays either. just have the church tradition of no coffee exsist unti lthe present day.
