News from the Lab: Update on YeastMan
By Neva Parker
The New Year started off with a big bang for us at
White Labs. January is always one of our busiest months of the year – I
guess everyone starts gearing back up after the lull of the holiday
season. Our new Frings yeast propagation equipment has been put to good
You have probably heard in several other issues of
CBQ about our yeast tracking and inventory software, YeastMan. We are
currently in the final stages of testing with this program and are
working on developing the reporting phase.
In the next few months, you will be receiving our new
Quality Control Certificates with more detailed information on your
yeast culture, all tracked and reported through the YeastMan system.
Once a yeast process begins, it is assigned a lot
number by YeastMan. Each lot is then used to fill different brewery
orders and we are able to provide accurate and comprehensive
certification for a single order by tracking each step with this unique
These new certificates will be printed directly from
the program itself with data such as initial test results, final test
results, gravity, pH, cell count, and viability. We have also developed
a process to track and report beer and yeast analysis tests, which we
implemented for our Big QC Day.
Interest in our Big QC Day was beyond our
expectations! Our goal was to encourage beer testing by offering
convenience and a low price, which we were able to do by obtaining a
large number of samples. The microbiological and analytical tests began
in late February, when the sample boxes began returning to White Labs.
The micro tests included testing for presence of wild
yeast and bacteria (aerobic & anaerobic), while the analytical tests
comprised density, real extract, color, IBU, alcohol by volume, and
total VDK (diacetyl).
The testing took place over the course of several
weeks, and of this writing the testing was still taking place. We used
the YeastMan bar-coding and tracking system to maintain accurate records
of all those samples and beer styles. We will also be able to use the
system to report results compared to the average of all samples tested,
overall and within a particular style.
Thank you to everyone for your participation in this
event! We look forward to the results of this and future test days.
