The Standard Reference Method or SRM [1] is one of several systems modern brewers use to specify beer color. Determination of the SRM value involves measuring the attenuation of light of a particular wavelength (430 nm) in passing through 1 cm of the beer, expressing the attenuation as an absorption and scaling the absorption by a constant (12.7 for SRM; 25 for EBC).
Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display. [3] In marine aquarium keeping, a refractometer is used to measure the salinity and specific gravity of the water. In the automobile industry, a refractometer is used to measure the coolant concentration.
The concept is used in the brewing and wine-making industries. Specific gravity is measured by a hydrometer, refractometer, pycnometer or oscillating U-tube electronic meter. The density of a wort is largely dependent on the sugar content of the wort. During alcohol fermentation, yeast converts sugars into carbon dioxide and alcohol. By ...
During the brewing process, humulone undergoes isomerization to form both cis- and trans- isohumulone which are responsible for the bitter taste of the beer. [13] Hops also contain lupulones , or beta acids; [ 13 ] these beta acids are not considered in the initial bittering of the wort as much as their alpha acid counterparts since they do not ...

In the Abbe refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism.
In brewing, attenuation refers to the conversion of sugars into alcohol and carbon dioxide by the fermentation process; the greater the attenuation, the more sugar has been converted into alcohol. A more attenuated beer is drier and more alcoholic than a less attenuated beer made from the same wort .
