Aloes have occasionally been used to restore decayed hops, though with such poor success that we should hardly think the experiment was often repeated. Professor Bradly, a Cambridge professor of botany, wrote as follows:—“I cannot help taking notice here of a method which has been used to stale and decayed hops, to make them recover their bitterness, which is to unbag them, and sprinkle them with aloes and water, which, I have known, has spoiled great quantities of drink about London; for even where the water, the malt, the brewer, {82} and the cellars are each good, a bad hop will spoil all: so that every one of these particulars should be well chosen before brewing, or else we must expect a bad account of our labour.” The age of hops is known by their appearance, odour, and feel. New unsulphured hops, for instance, when rubbed through the hand feel oily. In their first year they are of a bright green colour, have an aromatic smell and the lupuline is a bright yellow. In the second year they get darker, have a slightly cheesy odour, and the lupuline becomes a golden yellow. In the third year the lupuline is a dark yellow, the smell being about the same as in the second year. In the hedges about Canton is found a variety of hop growing wild. It has been named the _Humulus Japonicus_. “Although this species,” says Seemann, in his _Botany of the Voyage of H.M.S. Herald_, “was published many years ago by Von Siebold and Zuccarini, we still find nearly all our systematic works asserting that there is only _one_ species of Humulus, as there seems to be only one species of Cannabis. This, however, is a very good species, at once distinguished from the common Hop by the entire absence of those resinous spherical glands, with which the scales of the imbricated heads of the latter are scattered, and to which they owe their value in the preparation of beer, making the substitution of the one for the other for economical purposes an impossibility.” So much then for the first and principal use of hops—and yet a few lines more on the same subject; from Christopher Smart’s poem of the _Hop Garden_:— Be it so. But Ceres, rural Goddess, at the best Meanly supports her vot’ry, enough for her If ill-persuading hunger she repell, And keep the soul from fainting: to enlarge, To glad the heart, to sublimate the mind And wing the flagging spirits to the sky, Require the united influence and aid Of Bacchus, God of Hops, with Ceres joined, ’Tis he shall generate the buxom beer.
