What is the relationship between EBC and SRM?

The European Brewery Convention (EBC) and the Standard Reference Method (SRM) are both measurements used to quantify the color of beer, but they do so using different scales. The correct answer is that EBC is equal to SRM multiplied by 2.

This relationship comes from the fact that the EBC color measurement is generally considered to be twice that of the SRM measurement for the same sample of beer. This means if a beer measures, for example, 5 SRM, it would measure around 10 EBC. This factor of two helps brewers and beer enthusiasts convert between the two systems, which can often be found on labels or in brewing literature. Understanding this relationship is crucial for those involved in brewing and evaluating different beers, as it facilitates clear communication of beer color between regions that may prefer one measurement over the other.

The other options suggest either an entirely different relationship or a misunderstanding of how the two systems compare, highlighting the importance of knowing precise conversion factors in brewing.
