Consistent beers are made by lab testing. In this Brewery Pro article the team at Spark Breweries provides a comprehensive checklist for laboratory equipment for every size of brewery.
Which style is best? I hate hoppy crap. This beer tastes way better than that beer? I can’t believe people drink that mass produced swill? Now that’s drinkability!
Have you ever heard similar phrases to these? I think you have because I certainly have. The truth of the matter is that someone’s experience with what they eat and drink is totally subjective and everyone’s palate is different. Some people might be dipping their toe into their first craft beer, while others are crushing double oat cream chocolate hot cross bun flavoured IPAs on the regular.
What undoubtedly is the most important aspect we can control as brewers is the consistency of our beers, so no matter what beer is preferred by our customers they can expect the same thing the next time they pick up a beer. How do we achieve consistency? Well that’s done in the Lab. If you’re not measuring something it’s not science, I think that’s what my biology lecturer said…
What should I even be testing?
Enter the Analytica EBC if you want to know the best practice laboratory testing method and every test that is available to conduct within your brewery this is the place to go.
This will form the basis of your in house laboratory checks to maintain quality within your brewery. The relevance of a particular test is up to you, your process and the skills of those conducting the test.
What lab equipment does every craft brewery need at a minimum?
- Plato hydrometer & refractometer this can be inexpensive glass versions for the hydrometer and a simple or digital refractometer.
- Inexpensive option:
- a lab quality glass plato hydrometer for measuring apparent extract (FG) and a digital refractometer such as the Hanna instruments HI96841 for measuring original extract and mash extract (before fermentation), or brewhouse checks. Or
- The Anton Par Easydens, which will do all your brewhouse and cellar checks all in one.
- More expensive option: a DMA 35 Basic from Anton Paar which will also do all your brewhouse and cellar checks all in one.
- Inexpensive option:
- Laboratory Thermometer
- Laboratory pH meter and calibration buffer solutions
- Trade weight certified scales
- A device to measure C02/carbonation in your bright beer tanks or uni tanks – where ever you carbonate
- Inexpensive recommendations:
- The Taprite Beer Carbonation Tester or
- The Zahm SS-60 Volume Meter.
- Inexpensive recommendations:
If you package beer in house:
- A dedicated area to store packaged beer which has been assigned a unique batch code for traceability.
- Can double seam inspection tools
- Crown seal crimp gauge to ensure an adequate seal is made
Medium Sized to Large Production Brewery
If your brewery is starting to reach the 5000hl annual output range then the following equipment is worth its weight in gold:
- A dedicated climate control room as a lab
- A trained quality manager/microbiologist!
- A bench top digital density meter
- O2 meter (ppb)
- Digital CO2 metre
- Can or bottle headspace tester
- Magnetic stir plate plate with sti bars
- Carlsberg flask for yeast propagation
- A dedicated yeast propagation tank
