Styles are ever evolving,
and knowledge is paramount.
Here is a key to help decipher some data about our beers.
INTERNATIONAL BITTERNESS UNITS
A measurement of isomerized alpha acids from the hop additions in the kettle. For pale beers, it generally indicates strength and bitterness, but can be deceiving. IBU’s are also important in understanding the balance of the beer, and dark, malt pronounced beers may have high IBU’s in order to balance the profile without having a pronounced bitterness in the beer itself.
STANDARD REFERENCE MEASURE
A measurement of the color of the beer. Malt type, kettle additions, and fermentation all affect the final color. The higher the number, the darker the beer. This can be an indication of style and profile, but not accurately without other information.
Gravity units are the measurements of dissolved solids in a solution. The original gravity is a measurement of potential fermentable sugars prior to primary fermentation. It’s taken in reference to that of pure water at a certain temperature, which has a value of 1.000. Brewer’s use it for various data points, but it is used as an indication for potential abv.
The final gravity, in tandem with the original gravity, determine the alcohol content. FG also is an indication of how dry a beer is. The lower the number, the drier the beer. Agricolis and Aevum have low FG, while Caligo leaves more sugars behind for a heavier, sweeter beer.
unit abbreviation for barrel
One U.S. beer barrel is 31 gallons. Kegs come in fractions of a bbl and most kegs you would have encountered are ½ bbl or 15.5 gallons. Dancing Gnome Brewery is a 10 bbl brewhouse and will produce 310 gallons in a single brew.
Yielding 18-20 ½ bbl kegs depending on the beer.
