3rd Annual Big QC Day -
Regional Results
Below you will find selected regional
results for Big QC Day 2009. The results are broken down regionally
for the following tests, in order: IBUs, Alcohol, Calories,
Micro, and Micro by Test.
IBUs
The IBU scale provides a measure of the
hop derived bitterness of beer. The higher number, the greater the
bitterness. Porters range between 20 to 40, for instance, while
India Pale Ales are 40 or higher.
The American Society of Brewing Chemists International Method,
bitterness units, is used. Iso-alpha acids are chemically extracted
using the organic solvent iso-octane. The ultraviolet light
absorbance is measured in a precision spectrophotometer, and the
results are reported in bitterness units.

Micro
The graphics
shows the percentage of beers tested that
had any level of bacteria contamination. Overall, tests
showed that 89 percent of the beers were
bacteria-free, up from 84 percent in the
2nd Annual Big QC Day and 80 percent in the 1st Annual Big QC Day. For
those breweries that did have bacteria in their beer, White Labs
suggests increasing quality control efforts and testing.
