BEAD-Proof, a term used by our distillers to express that fort of proof of the standard strength of spirituous liquors, which consists in their having, when shaken in a phial, or poured from on high into a glass, a crown of bubbles, which stand on the surface some time after. This is esteemed a proof that the spirit consists of equal parts of rectified spirits and phlegm. This is a fallacious rule as to the degree of strength in the goods; because any thing that will increase the tenacity of the spirit, will give it this proof, though it be under the due strength. Our malt-distillers spoil the greater part of their goods, by leaving too much of the flinking oil of the malt in their spirit, in order to give it this proof when somewhat under the standard strength. But this is a great deceit on the purchasers of malt spirits, as they have them by this means not only weaker than they ought to be, but flinking with an oil that Bead-Proof they are not easily cleared of afterwards. On the other hand, the dealers in brandy, who usually have the art of sophisticating it to a great nicety, are in the right when they buy it by the strongest bead-proof, as the grand mark of the best; for being a proof of the brandy containing a large quantity of its oil, it is, at the same time, a token of its high flavour, and of its being capable of bearing a very large addition of the common spirits of our own produce, without betraying their flavour, or losing its own. We value the French brandy for the quantity of this essential oil of the grape which it contains; and that with good reason, as it is with us principally used for drinking as an agreeably flavoured cordial: but the French themselves, when they want it for any curious purposes, are as careful in the rectification of it, and take as much pains to clear it from this oil, as we do to free our malt spirits from that nauseous and fetid oil which it originally contains.
