From Wikipedia, the free encyclopedia
Degrees Lovibond or
°L scale is a measure of the color of a substance, usually
beer,
whiskey, or
sugar solutions. The
Standard Reference Method (SRM) and EBC method have largely replaced it, with the SRM giving results approximately equal to the °L. The determination of the degrees lovibond takes place by comparing the color of the substance to a series of amber to brown glass slides, usually by a
colorimeter. The scale was devised by
Joseph Williams Lovibond.
