Breweries and Diftilleries, 



The immenfe coppers ufed in thefe and other 

 great publick undertakings, being generally un- 

 tinned, are peculiarly fubjedl to corrofion, and there- 

 fore demand uncommon attention to cleanlinefs. 

 In brewhoufes, if any portion of wort (be it ever 

 fo fmall) is left to (land in the copper when cold, 

 or longer than abiblutely neceflary, without being 

 well cleaned out, it not only difpofes the whole 

 quantity of the fubfequent liquor fpeedily to turn 

 four, but, what is worfe, impregnates it with the 

 poifon of copper, incapable of being corre<fled by 

 the fucceeding fermentation. 



The evil is greatly increafed by a warm feafon; 

 hence the frequent complaints of dale beer, parti- 

 cularly in the fummer time, among many families. 

 Such liquor within two or three weeks becomes 

 acid, and unfit for ufe; and if the impregnation of 

 copper is confiderable, it proves emetick, and highly 

 pernicious to thofe who drink it as daily beverage. 

 On the other hand, thofe brewers who pay clofe 

 attention to their veflels, and reward their fervants 

 for doing the fame, prevent this unwholefome im- 

 pregnation altogether, and have the additional fatis- 

 faCtion to find that their beer, inftead of being re- 

 turned on their hands as unfound, remains fweei; 

 and entire even in the hotted fummers.
