Jesse Takes the BJCP Exam !!!!!

Jesse Mertz, our fearless leader, recently sat for the Beer Judge Certification Exam, after taking prep classes put on by the Concord Area Homebrewers.  This is what he had to say about it:

The online pre-test was 200 multiple-choice/multiple-answer questions with no partial credit, which must be taken in 60 minutes.  I did pass that in order to sit for the exam.  The tasting portion was proctored, and was held at the Fisher Cats Stadium.  We had 15 minutes per beer to do a complete scoresheet, with a 15-minute break between beers 3 and 4.  Approximately 3 of the 6 had minor flaws, with 1 beer containing major flaws.  I would not attempt a BJCP certification without a fairly strong brewing background – I’m not sure how the non-brewers pass this thing, really.  Certainly challenging, and I learned a great deal, too.  The biggest thing that helped me was reading Zymurgy’s ‘Commercial Calibration’, studying the BJCP style guidelines themselves, drinking lots of beer and styles that I would not normally pursue, and filling out scoresheets on both commercial and customer beers.

If you are thinking of this exam, I guess you will have to knuckle down and study hard, which will also include tasting lots of beer in different styles.

Here are some resources

Hydrometer? Refractometer? What are they?

If you brew beer or make wine then you know that most everything we do is done to get fermentable sugar out of grain or fruit. We do this all just to give it to some hungry yeast in order to achieve our final result – alcohol!  This brings us to measuring those sugars, which we do to monitor the process and scientifically assess the health of the fermentation, as well as determine the strength of the final drink.  Fortunately we have some tools to provide that information, and they are so simple to use that no homebrewer should be without them.  There are a few scales that you should be aware of:

Brix: Used primarily in the wine industry.

Plato: Used by most professional brewers.

Specific Gravity: used by home brewers and some brewing professionals.

Balling: A measuring system used by vintners that has since fallen by the wayside.

There are many other industry dependent scales but we will be talking about the ones applicable to beer and wine. The two main devices used by home brewers are:

The Hydrometer

The simplest of all the devices, it was invented by Hypatia of Alexandria in the days before the dark ages fell and threw science back a thousand years.  A hydrometer measures the amount of sucrose in a liquid. The higher the amount of sugar per unit of liquid the higher the number will be on the scale.  The typical hydrometer consists of a weighted bulb at the base and a stem at the top.  Inside the stem is an insert with a scale showing Specific Gravity, Plato, or Brix, with sometimes Potential Alcohol as well.  The scale most homebrewers use (generally) is specific gravity, and it runs from .990 to 1.160.The Refractometer

A refractometer measures the sucrose content of a liquid by the liquid’s ability to bend a ray of light through a prism. These take only a drop of wort or must and are in some cases automatically thermally corrected.  Refractometers measure in Brix and/or Specific Gravity with only a drop or two of wort or must placed on the lens.


Both devices require calibration, for the hydrometer the testing jar should be filled with distilled water at 68 degrees.  If the measurement is more or less than 1.000, then note should be made for future brew sessions to adjust the reading by the degree of change.  For the Refractometer, a drop of distilled water is placed on the lens, the cover is closed making sure there are no air bubbles or dry spots.  Look through the lens and adjust the calibration screw till the scale is at zero Brix (or what ever scale it has in it).

The Pro’s and Con’s

The advantage of a Refractometer is the ability to analyze the liquid despite its temperature at anytime over the course of brewing.  The advantage of the Hydrometer is its cost, and ease of use.  Also once there is alcohol in the liquid the Refractometer needs a calibration table where as the Hydrometer needs a calibration table based only on the temperature of the liquid involved.

At Kettle to Keg we carry both Hydrometers (in many styles) as well as Refractometers – and if you need help learning how to use them we have knowledgeable staff on hand to help you!  With a little practice you can have a big impact on the quality of your brewing.
