There are currently two color scales in common use: SRM in the US, and EBC in Europe.

The SRM (Standard Research Method) scale is based on an older scale called degrees Lovibond, and for all practical purposes SRM and degree Lovibond are identical.

American brewers use Lovibond to describe malts, while SRM is used to describe the color of the finished beer.

Hop Calculator

Calculation of hop rate required to obtain a specific bitterness (BU's)

Required value for calculations	Note and recommendations
Alpha Acid of Hop [%]	1 KG -> mg of bitterness
Required BU's [mg/ltr]	Select BU 7 BU - Budweiser 15 - 20 BU - Lager beer style 15 - 20 BU - Mild beer style 17 - 35 BU - Bitter beer style 30 - 50 BU - Stout beer style 40 - 65 BU - IPA beer style Above 65 BU
Alpha utilisation [%]	Depends of brewing equipment and production conditions
Quantity of beer to brew [barel]	. . . X 164 = [Liters]
Required Hops [kg]
This is a rough guide for calculating the quantity of hops for bittering purposes. BU - Bitterness units according to beer styles from 7 - 65 [mg/ltr]. Above 65 BU it is difficult to perceive the extra bitterness.
