2016年6月7日 · The ASBC Beer Color scale has a range of approximately 1 to 11 units, with the more yellow, pale worts at the low end of the scale and the redder color of dark worts, beers and caramels at the upper end of the scale.

2012年7月15日 · The ASBC method uses a spectrophotometer to assess the amount of light absorbed by beer in a 0.5-in. (1.25-cm) i.d. glass cuvette when illuminated with light at the specific wavelength of 430 nm; the SRM color rating is equal to 10 times this absorbance value.

The ASBC method for beer color and turbidity is: ASBC Beer-10, Color of Beer Part A, Spectrophotometric Color Method. The ASBC color metric is based on a spectral absorbance measurement at 430 nm of clarified beer using a UV-VIS spectrophotometer. The ASBC Beer Color scale has a range of approximately 1 to 11 units.

The ASBC and EBC measurements are now identical (both done at the same wavelength and in the same size cuvette) but the scaling is different. A photometer or spectrophotometer is used to measure the attenuation of deep blue (violet) light at 430 nm, as it passes through 1 cm of beer contained in a standard 1 cm by 1 cm cuvette.

An optek AF26 color monitor compensates for any background turbidity to measure proper wort color. Color dosing in a brewery can be monitored with an optek AS16 probe sensor

2016年12月2日 · ASBC色度指标是基于一个简单的光谱吸光度：在430nm波长下用光径0.5英寸比色皿测得（去除碳酸的）啤酒的吸光度。 在用ASBC测量色度的同时，也可以用10mm光径的比色皿测酒样的EBC色度。 这里用到一个转换因子1.27。 仪器校正时用蒸馏水做参比。 ASBC浊度是基于一个简单的光谱方法：测量蓝色430nm和红色区域700nm两个点的吸光度。 出于同样的原因,天空是蓝色的。 如果蓝色光谱和红色光谱的吸光率不同，那么液体的浊度就可以被测出来。 …

2024年9月12日 · ASBC 颜色指标基于使用0.5英寸光程池在430 nm处对脱碳啤酒进行简单的光谱吸光度 （A） 测量。 该公式最初定义为： ASBC 啤酒色度 = 10*（A1/2）， 430 nm. 在允许使用用于测量EBC啤酒颜色的相同10mm光程的比色皿同时测量和报告ASBC啤酒颜色时，使用1.27的转换因子来缩放使用10mm光程的比色皿测量的吸光度，以吸光度原始0.5英寸光程。 A1/2，430nm=1.27*A10mm@430nm. 当样品在10mm光程长度的池中测量时，所得的ASBC …

2008年4月29日 · In 1950 the ASBC adopted the Standard Reference Method (SRM) color system. Separately the Europeans developed another visual system called the European Brewing Convention (EBC). It originally used visual comparison, but some 25 years later changed to use a spectrophotometer in a slightly different way than SRM. Measuring Beer Color.

Color is experimentally obtained by using a spectrophotomer to determine the absorbance or transmittance of the sample. This method determines the color of beer by the spectrophotometric color method, the photometric method, and tristimulus analysis.
