This Month is esteemed one of the principal Seasons for brewing of Malt Liquors for long keeping; the Reason is, because the Air at this time of the Year is temperate, and contributes to the good Working or Fermenting the Drink, which chiefly promotes its Preservation and good Keeping: for very cold Weather prevents the free Fermentation or Working of Liquors, as well as very hot Weather; so that if we brew in very cold Weather, unless we use some Means to warm the Cellar while new Drink is Working, it will never clear itself as it ought to do; and the same Misfortune will it lie under, if in very hot Weather the Cellar is not put in a temperate state, the Consequence of which will be, that such Drink will be Muddy and Sour, and, perhaps, never recover; or if it does, perhaps not under two or three Years. Again, such Misfortunes are often owing to the badness of the Cellars; for where they are dug in springy Ground, or are subject to Wet in the Winter, then the Drink will chill, and grow flat and dead. But where Cellars are of this sort, it is adviseable to make your great Brewings in this Month rather than in _October_; for you may keep such Cellars temperate in Summer, but cannot warm them in Winter, and so your Drink brew'd in _March_ will have due time to settle and adjust itself before the Cold can do it any great harm. It is adviseable likewise to build your Cellars for keeping of Drink, after such a manner, that none of the external Air may come into them; for the variation of the Air abroad, was there free admission of it into the Cellars, would cause as many Alterations in the Liquors, and so would keep them perpetually disturb'd and unfit for drinking. I know some curious Gentlemen in these things, that keep double Doors to their Cellars, on purpose that none of the outward Air may get into them, and they have good reason to boast of their Malt-Liquors. The meaning of the double Doors, is to keep one shut while the other is open, that the outward Air may be excluded; such Cellars, if they lie dry, as they ought to do, are said to be cool in Summer, and warm in Winter, tho' in reality, they are constantly the same in point of Temper: they seem indeed cool in hot Weather, but that is because we come into them from an hotter abroad; and so they seem to us warm in Winter, because we come out of a colder Air to them; so that they are only cold or warm comparatively, as the Air we come out of is hotter or colder. This is the Cafe, and a Cellar should be thus dispos'd if we expect to have good Drink. As for the Brewing Part itself, I shall leave that to the Brewers in the several Counties in _England_, who have most of them different Manners even of Brewing honestly. What I shall chiefly touch upon, besides what I shall speak of Cellaring, will relate to Water, Malt, Hops, and the keeping Liquors.
