A Treatise on the Brewing of Beer
Coolers will last many years without repairing; when, on the contrary, cooling tubs, &c. are frequently out of repair, and are as lumber, being of little or no use, except when used in brewing.
From the before mentioned improvements you will always finish your brewing before a late hour at night, which will enable you to pay the more attention to the worts in the tuns, &c.
Care should be taken to keep the brewing utensils as clean and as sweet as those used in a dairy; for without cleanliness it is impossible to have your beer in a good and wholesome state.
The copper should be cleaned after each brewing, as it will keep it bright; when it is used but seldom, and in wet or damp weather, the verdigrease will appear, but care should be taken to examine and clean it, previous to the warier's being put in for brewing.
