The reader need scarcely be told, that of no article there are more varieties than of porter. This, no doubt, arises from the different mode of manufacturing the beer, although the ingredients are the same. This difference is more striking in the porter manufactured among country brewers, than it is in the beer brewed by the eminent London porter brewers. The totality of the London porter exhibits but very slight differences, both with respect to strength or quantity of spirit, and solid extractive matter, contained in a given bulk of it. The spirit may be stated, upon an average, to be 4,50 per cent. in porter retailed at the publicans; the solid matter, is from twenty-one to twenty-three pounds per barrel of thirty-six gallons. The country-brewed porter is seldom well fermented, and seldom contains so large a quantity of spirit; it usually abounds in mucilage; hence it becomes turbid when mixed with alcohol. Such beer cannot keep, without becoming sour.
It has been matter of frequent complaint, that ALL the porter now brewed, is not what porter was formerly. This idea may be true with some exceptions. My professional occupations have, during these twenty-eight years, repeatedly obliged me to examine the strength of London porter, brewed by different brewers; and, from the minutes made on that subject, I am authorised to state, that the porter now brewed by the eminent London brewers, is unquestionably stronger than that which was brewed at different periods during the late French war. Samples of brown stout with which I have been obligingly favoured, whilst writing this Treatise, by Messrs. Barclay, Perkins, and Co.—Messrs. Truman, Hanbury, and Co.—Messrs. Henry Meux and Co.—and other eminent brewers of this capital—afforded, upon an average, 7,25 per cent. of alcohol, of 0,833 specific gravity; and porter, from the same houses, yielded upon an average 5,25 per cent. of alcohol, of the same specific gravity;[55] this beer received from the brewers was taken from the same store from which the publicans are supplied.
It is nevertheless singular to observe, that from fifteen samples of beer of the same denominations, procured from different retailers, the proportions of spirit fell considerably short of the above quantities. Samples of brown stout, procured from the retailers, afforded, upon an average, 6,50 per cent. of alcohol; and the average strength of the porter was 4,50 per cent. Whence can this difference between the beer furnished by the brewer, and that retailed by the publican, arise? We shall not be at a loss to answer this question, when we find that so many retailers of porter have been prosecuted and convicted for mixing table beer with their strong beer; this is prohibited by law, as becomes obvious by the following words of the Act.[56]
"If any common or other brewer, innkeeper, victualler, or retailer of beer or ale, shall mix or suffer to be mixed any strong beer, ale, or worts, with table beer, worts, or water, in any tub or measure, he shall forfeit 50l." The difference between strong and table beer, is thus settled by Parliament.
"All beer or ale[57] above the price of eighteen shillings per barrel, exclusive of ale duties now payable (viz. ten shillings per barrel,) or that may be hereafter payable in respect thereof, shall be deemed strong beer or ale; and all beer of the price of eighteen shillings the barrel or under, exclusive of the duty payable (viz. two shillings per barrel) in respect thereof, shall be deemed table beer within the meaning of this and all other Acts now in force, or that may hereafter be passed in relation to beer or ale or any duties thereon."
