What color is your beer? This colorimeter was used for comparing the color of beer samples to a standard range of colors for malt beverages. The many shades of beer are achieved by using different amounts and varieties of malt in the brewing process. Pale lager, Pilsener, amber ale, bock, porter, stout, and imperial stout are just some of the different types of beer that can be distinguished by both taste and color. ??
The brewmaster would place a sample of beer in a clear glass container on the instrument’s shelf. By turning the wheel, the operator would match the color of the sample with one of the tinted panes of glass. Each of the colors in the wheel represents a standard measurement called "Degrees Lovibond." ? Happy #NationalBeerDay! #BeerHistory #FoodHistory #SmithsonianFood #CheersToHistory ?
