Alcoholmeter Tessa Scale

The alcoholmeter with the aid of a copper parrot spout attached to distillate outlet will provide constant and accurate readings while the distillate is exiting the condenser spout. Nearly every country has its own alcoholmeter or a special scale model, Portugal and Spain are no exception. This alcoholmeter comes with a Tessa scale, specifically used in the northwest part of Portugal and Spain in the distillation of “Verde” wines (a naturally sparkling wine) due to its lower alcoholic volume - commonly 9 %v/v.
