Grappa Alcoholmeter Cartier & Gay Lussac Scale

This alcoholmeter with the aid of a copper parrot spout, which is attached to the distillate outlet of the condensing recipient, will provide constant and accurate readings of the exiting distillate. This model includes both the Cartier and Gay Lussac scale. The Cartier scale was introduced in 1771 for the purpose of testing liquor, and is still favored by many even though it was replaced by the Gay Lussac scale in 1824 better known as alcohol by volume (ABV) and often expressed as a percentage of the total volume.
