There are several methods used in drying of Malts, as the Iron Plate-frame, the Tyle-frame, that are both full of little Holes: The Brass-wyred and Iron-wyred Frame, and the Hair-cloth; the Iron and Tyled one, were chiefly Invented for drying of brown Malts and saving of Fuel, for these when they come to be thorough hot will make the Corns crack and jump by the fierceness of their heat, so that they will be roasted or scorch'd in a little time, and after they are off the Kiln, to plump the body of the Corn and make it take the Eye, some will sprinkle water over it that it may meet with the better Market. But if such Malt is not used quickly, it will slacken and lose its Spirits to a great degree, and perhaps in half a Year or less may be taken by the Whools and spoiled: Such hasty dryings or scorchings are also apt to bitter the Malt by burning its skin, and therefore these Kilns are not so much used now as formerly: The Wyre-frames indeed are something better, yet they are apt to scorch the outward part of the Corn, that cannot be got off so soon as the Hair-cloth admits of, for these must be swept, when the other is only turned at once; however these last three ways are now in much request for drying pale and amber Malts, because their fire may be kept with more leisure, and the Malt more gradually and truer dyed, but by many the Hair-cloth is reckoned the best of all.
Malts are dryed with several sorts of Fuel; as the Coak, Welch-coal, Straw, Wood and Fern, &c. But the Coak is reckoned by most to exceed all others for making Drink of the finest Flavour and pale Colour, because it sends no smoak forth to hurt the Malt with any offensive tang, that Wood, Fern and Straw are apt to do in a lesser or greater degree; but there is a difference even in what is call'd Coak, the right sort being large Pit-coal chark'd or burnt in some measure to a Cinder, till all the Sulphur is consumed and evaporated away, which is called Coak, and this when it is truly made is the best of all other Fuels; but if there is but one Cinder as big as an Egg, that is not thoroughly cured, the smoak of this one is capable of doing a little damage, and this happens too often by the negligence or avarice of the Coak-maker: There is another sort by some wrongly called Coak, and rightly named Culme or Welch-coal, from _Swanzey_ in _Pembrokeshire_, being of a hard stony substance in small bits resembling a shining Coal, and will burn without smoak, and by its sulphureous effluvia cast a most excellent whiteness on all the outward parts of the grainy body: In _Devonshire_ I have seen their Marble or grey Fire-stone burnt into Lime with the strong fire that this Culme makes, and both this and the Chark'd Pit-coal affords a most sweet moderate and certain fire to all Malt that is dryed by it.
