BEER.
107
Sometimes the first wort is brewed by itself into strong ale, the Second by itself into an} n ei mediate quality : and the third into small beer : but this practice is not much fol-l°wed m this country.
We shall now treat of the boiling in of the hops ; The wort drawn from the mash-un, whenever it is pumped into the copper, must receive its allowance of hops. Besidesevaporating off a portion of the water, and thereby concentrating the wort, boiling has awotold object. In the first place, it coagulates the albuminous matter, partly by themat, and partly by the principles in the hops, and thereby causes a general clarification” the whole mass, with the effect of separating the muddy matters in a flocculent form,econdly, during the ebullition, the residuary starch and hordeine of the malt are con-verted into a limpid sweetish mucilage, the dextrine above described ; while some of theglutinous stringy matter is rendered insoluble by the tannin principle of the hops, whichs till further the clearing of the wort. By both operations the keeping quality®. ta e beer is improved. This boil must be continued during several hours; a longerone for the stronger, and a shorter for the weaker beers. There is usually one seventh° T one sixth part of the water dissipated in the boiling copper. This process is known° ?*(- e coat m u ed a sufficient time, if the separation of the albuminous flocks is distinct,an .d if these are found, by means of a proof gauge suddenly dipped to the bottom, to beoo lected there, while the supernatant liquor has become limpid. Two or three hours’oil is deemed long enough in many well-conducted breweries; but in some of those ine glum, the boiling is continued from 10 to 15 hours, a period certainly detrimental tolearor na derived from the hop.
Many p re f er adding the hops when the wort has just come to the boiling point.
, e,r efTeet is to repress the further progress of fermentation, and especially the passageo the acetous stage, which would otherwise inevitably ensue in a few days. In this1 spee '’i° other vegetable production hitherto discovered can be a substitute for thej. Qr P ' The odorant principle is not so readily volatilized as would at first be imagined;im Wllen bo P i s mixed with strong beer wort and boiled for many hours, it can stillhot ^ a very considerable degree of its flavor to weaker beer. By mere infusion inTh t r ? c water > without boiling, the hop loses very little of its soluble principles,barl tann ‘ n oP the hop combines, as we have said, with the vegetable albumen of the„l , e ^ J an d helps to clarify the liquor. Should there be a deficiency of albumen andlated't 1 h* n conse quence of the mashing having been done at such a heat as to have coagu-jlj them beforehand, the defect may be remedied by the addition of a little gelatine toboiled 0 "* copper > mther in the form of calf’s foot, or of a little isinglass. If the hops beflavor-'h ^ W ° rt *" or a i° n " er P er i°fl than 5 or 6 hours, they lose a portion of their fineors th’ ° Ut tbe ‘ r na tural flavor be rank, a little extra boiling improves it.
