Wie schon Donnerstag gesagt, wollte ich den Artikel über Proof abschreiben, da ich ihn lustig und interessant finde. Ihr könnt in in "Vintage Barware" auf Seite 126 finden.
Hier ist er, für alle die dass Buch nicht haben:
"It´s not showing your i.d. to gain admission to a bar as a youngster. Proof is an ancient term and refers to alcohol content. As a means of standardization in England, in the early years of alcohol manufaturing, a test was formed; a measured amount of alcohol mixed with a measured of water waspoured on gunpowder. The least amount of alcohol in the mixture that would still allow ignition of the gunpowder was called proof. If a great flame arose, the alcohol was too high. When a steady blue flame was noted, the spirit was considered the right strength. If the flame shuttered, there was too much water in the beverage. When 50% alcohol was blended with 50% water, the steadiest flame of all was perceived. They termed this blend "100% proof".
When the hydrometer was invented late in the eighteenth century, it was found that if placed in liquor, one could determite its density and calculate the amount of alcohol by the depth to which the hydrometer or weighted float sank. In 1816 Bartholomew Sikes improved the hydrometer, and Sike´s measurement of proof is still in use today. This system was explained to me by my uncle, Ray Foley, when he said "proof spirit is spirit which at 51 F. wighs 12/13 of an equal measure of distilled water, having at 51 degrees a specific gravity of .92308 in a mixtue of 57% pure alcohol and 43% water. In England, proof is 52,10%of alcohol by volume at 60 degrees F. In the USA , it´s 50% of alcohol by volume at 60 degrees F... so if that bottle in of vodka in the freezer says 100 proof, we know it´s 50% pure alcohol, and 80 proof means it´s 40% alcohol". Thank you uncle Ray."
