Adhumulone

~15% of Alpha Acids. Oxidizes into 2-methylbutryic acid which has an odor remniscent of Roquefort cheese.

Humulone

Primary Alpha Acid. ~20%-50% Primary aa found in most hops. Known for a “soft bitter flavor that is far from harsh.

Irish Moss

Clearing agent. Added to boil, ~15 min before end, to make proteins clump together.

Alcohol By Volume (ABV)

The percentage of a liquid that is alcohol.

Original Gravity (OG)

Original Gravity: A Measure of the sugar contents (density) of the wort. Measured in Specific Gravity (SG).A measure of mash efficiency. Used together with FG to calculate ABV.

Final Gravity (FG)

Final Gravity: A measure of the sugar contents (density) of the finished beer. Measured in Specific Gravity (SG). A measure of fermentation efficiency.Used together with OG to calculate ABV.

Specific Gravity (SG)

A measure of the sugar contents (density) of a liquid. Measured with a Hydrometer. It is common to measure two specific SG points: OG and FG. Together these two measurements are used to calculabe the ABV of the finished beer in addition to the apparent attenuation of the fermentation. Original Gravity (OG) Original Gravity: A […]
