THE LONDON and COUNTRY BREWER
1736CHAP. V.
Of the Nature of several Waters and their use in Brewing. And first of Well-waters.Water next to Malt is what by course comes here under Consideration as a Matter of great Importance in Brewing of wholsome fine Malt-liquors, and is of such Consequence that it concerns every one to know the nature of the water he Brews with, because it is the Vehicle by which the nutritious and pleasant Particles of the Malt and Hop are conveyed into our Bodies, and there becomes a diluter of our Food: Now the more simple and freer every water is from foreign Particles, the better it will answer those Ends and Purposes; for, as Dr. Mead observes, some waters are so loaded with stony Corpuscles, that even the Pipes thro' which they are carried, in time are incrusted and stopt up by them, and is of that petrifying nature as to breed the Stone in the Bladder, which many of the Parisians have been instances of, by using this sort of water out of the River Seine. And of this Nature is another at Rowel in Northamptonshire, which in no great distance of time so clogs the Wheel of an overshot Mill there, that they are forced with, convenient Instruments to cut way for its Motion; and what makes it still more evident, is the sight of those incrusted Sides of the Tea-kettles, that the hard Well-waters are the occasion of, by being often boiled in them: And it is further related by the same Doctor, that a Gentlewoman afflicted with frequent returns of violent Colick Pains was cured by the Advice of Van Helmont, only by leaving off drinking Beer brewed with Well-water; It's true, such a fluid has a greater force and aptness to extract the tincture out of Malt, than is to be had in the more innocent and soft Liquor of Rivers: But for this very reason it ought not, unless upon meer necessity, to be made use of; this Quality being owing to the mineral Particles and alluminous Salts with which it is impregnated. For these waters thus saturated, will by their various gravities in circulation, deposit themselves in one part of the animal Body or other, which has made some prove the goodness of Water by the lightness of its body in the Water Scales, now sold in several of the London Shops, in order to avoid the Scorbutick, Colicky, Hypochondriack, and other ill Effects of the Clayey and other gross Particles of stagnating Well-waters, and the calculous Concretions of others; and therefore such waters ought to be mistrusted more than any, where they are not pure clear and soft or that don't arise from good Chalks or stony Rocks, that are generally allowed to afford the best of all the Well sorts.
Spring-waters are in general liable to partake of those minerals thro' which they pass, and are salubrious or mischievous accordingly.
At Uppingham in Rutland, their water is said to come off an Allum-rock, and so tints their Beer with its saline Quality, that it is easily tasted at the first Draught. And at Dean in Northamptonshire, I have seen the very Stones colour the rusty Iron by the constant running of a Spring-water; but that which will Lather with Soap, or such soft water that percolates through Chalk, or a Grey Fire-stone, is generally accounted best, for Chalks in this respect excell all other Earths, in that it administers nothing unwholsome to the perfluent waters, but undoubtedly absorps by its drying spungy Quality any ill minerals that may accompany the water that runs thro' them. For which reason they throw in, great Quantities of Chalk into their Wells at Ailsbury to soften their water, which coming off a black Sand-stone, is so hard and sharp that it will often turn their Beer sour in a Week's time, so that in its Original State it's neither fit to Wash nor Brew with, but so long as the Alcalous soft Particles of the Chalk holds good, they put it to both uses.
River-waters are less liable to be loaded with metallick, petrifying, saline and other insanous Particles of the Earth, than the Well or Spring sorts are, especially at some distance from the Spring-head, because the Rain water mixes with and softens it, and are also much cured by the Sun's heat and the Air's power, for which reason I have known several so strict, that they won't let their Horses drink near the first rise of some of them; this I have seen the sad Effects of, and which has obliged me to avoid two that run cross a Road in Bucks and Hertfordshire: But in their runnings they often collect gross Particles from ouzy muddy mixtures, particularly near Town, that make the Beer subject to new fermentations, and grow foul upon alteration of weather as the Thames water generlly does; yet is this for its softness much better than the hard sort, however both these waters are used by some Brewers as I shall hereafter observe; but where a River-water can be had clear in a dry time, when no great Rain has lately fell out of Rivulets or Rivers that have a Gravelly, Chalky, Sandy or Stone-bottom free from the Disturbance of Cattle, &c. and in good Air, as that of Barkhamstead St. Peters in Hertfordshire is; it may then justly claim the name of a most excellent water for Brewing, and will make a stronger Drink with the same quantity of Malt than any of the Well-waters; insomuch that that of the Thames has been proved to make as strong Beer with seven Bushels of Malt, as Well-water with eight; and so are all River-waters in a proportionable degree, and where they can be obtain'd clean and pure, Drink may be drawn fine in a few Days after Tunning.
Rain-water is very soft, of a most simple and pure nature, and the best Diluter of any, especially if received free from Dirt, and the Salt of Mortar that often mixes with it as it runs off tyled Roofs; this is very agreeable for brewing of Ales that are not to be kept a great while, but for Beers that are to remain some time in the Casks, it is not so, well, as being apt to putrify the soonest of any.
Pond-waters; this includes all standing waters chiefly from Rain, and are good or bad as they happen; for where there is a clean bottom, and the water lies undisturbed from the tread of Cattle, or too many Fish, in an open sound Air, in a large quantity, and where the Sun has free access; it then comes near, if not quite as good as Rain or River-waters, as is that of Blew-pot Pond on the high Green at Gaddesden in Hertfordshire and many others, which are often prefer'd for Brewing, even beyond many of the soft Well-waters about them. But where it is in a small quantity, or full of Fish (especially the sling Tench) or is so disturbed by Cattle as to force up Mud and Filth; it is then the most foul and disagreeable of all others: So is it likewise in long dry Seasons when our Pond-waters are so low as obliges us to strain it thro' Sieves before we can use it, to take out the small red Worms and other Corruptions, that our stagnant waters are generally then too full of. The latest and best Doctors have so far scrutinized into the prime Cause of our British malady the Scurvy, as to affirm its first rise is from our unwholesome stagnating waters, and especially those that come off a clayey surface, as there are about Londonderry and Amsterdam, for that where the waters are worst, there this Distemper is most common, so that in their Writings they have put it out of all doubt, that most of our complicated symptoms that are rank'd under this general Name, if they don't take their beginning from such water, do own it to be their chief Cause.
