What is Bu Gu beer?
BU stands for Bitterness Units and GU stands for Gravity Units. By dividing your bitterness units by your gravity units you arrive at a ratio which lets you know how bitter your beer is.
How is Bu Gu ratio calculated?
To calculate the BU:GU ratio, simply multiply the original gravity by 1000 then subtract 1000 to get the gravity units: (1.050 * 1000)-1000 = 50. Another way to say this is move the decimal place over three spaces and get rid of the “1” on the left. Now divide the IBUs by the gravity units to get the BU:GU ratio.
