I'm not so sure about this, I have done some research on the topic for a book I am working on and it appears that in some cities at certain times, safe water was hard to come by and for that and other reasons people consumed beer/wine as their primary beverage and with nearly every meal. I have studied this in the context of the effects on society of coffee and coffee houses that came with displacing beer and taverns as the main beverages and gathering points of society in 17th and 18th century England.<p>Here is an excerpt from James Howell in 1660:<p>"Tis found already, that this coffee drink hath caused a greater sobriety among the Nations. Whereas formerly Apprentices and clerks with others used to take a morning draught of Ale, Beer or Wine, which, by the dizziness they cause in the Brain, made many unfit for business, they use now to play the Good-fellows in this wakeful and civil drink"<p>And another from the historian Michelet:<p>...For at length the tavern has been dethroned, the detestable tavern where, half a century ago, our young folks rioted among wine-tubs and harlots. Fewer drunken songs o' night time, fewer nobles lying in the gutter... Coffee the sobering beverage, a mighty nutriment of the brain, unlike spirituous liquors, increases purity and clarify; coffee, which clears the imagination of fogs and heavy vapours, which illumines the reality of things with the white light of truth; anti-erotic coffee, which at length substitutes stimulation of the mind for stimulation of the sexual faculties!"<p>[1] <a href="https://books.google.com/books?id=Gbmhwpxe9usC&pg=PA10&lpg=PA10&dq=hath+caused+a+greater+sobriety+among+the+Nations.+Whereas+formerly+Apprentices+and+clerks+with+others+used+to+take+a+morning+draught+of+Ale,+Beer+or+Wine,+which,+by+the+dizziness+they+cause+in+the+Brain,+made+many+unfit+for+business,+they+use+now+to+play+the+Good-fellows+in+this+wakeful+and+civil+drink&source=bl&ots=rPgKd9fknG&sig=mVVqFbrC4KEv71lLqstfnag-BKg&hl=en&sa=X&ei=nfXbVKjCMY_ooASQqYKYCQ&ved=0CCMQ6AEwAQ#v=onepage&q=hath%20caused%20a%20greater%20sobriety%20among%20the%20Nations.%20Whereas%20formerly%20Apprentices%20and%20clerks%20with%20others%20used%20to%20take%20a%20morning%20draught%20of%20Ale%2C%20Beer%20or%20Wine%2C%20which%2C%20by%20the%20dizziness%20they%20cause%20in%20the%20Brain%2C%20made%20many%20unfit%20for%20business%2C%20they%20use%20now%20to%20play%20the%20Good-fellows%20in%20this%20wakeful%20and%20civil%20drink&f=false" rel="nofollow">https://books.google.com/books?id=Gbmhwpxe9usC&pg=PA10&lpg=P...</a>
