"Only a pint at breakfast-time, and a pint and a half at eleven o'clock, and a quart or so at dinner. And then no more till the afternoon; and half a gallon at supper-time"

Beer was consumed daily in 1600s England.  The purity of water could seldom be guaranteed. Alcoholic drinks provided a popular alternative, having been boiled as part of the brewing process. Beer also provided a considerable amount of the daily calories consumed by working men.  Households generally brewed their own beer.

John insists that the average intake of an English yeoman is not at all excessive. His estimation of daily intake amounts to just under 5 litres of beer, taken over the course of the day from breakfast through to supper.
