Bringing the QC Lab into the Brewery

Brewmetrix is on a mission to eliminate the hassle and chemicals involved in the quality control (QC) of the brewing process. “The vision is to have a chemical-free QC lab inside the brewery,” said VP of R&D for Brewmetrix, Dr. Sydney Sukuta. “All the quality-control tests that the brewery would normally send out to an outside testing lab can be done quickly and by in-house personnel – no special degrees or training required.”

Who is Brewmetrix?

Brewmetrix is a start-up company based in Nevada, using a patented approach to analyze liquids. The initial product, targeting small- to mid-sized breweries, is a complete QC system to measure any liquid property of interest to the professional brewer. The system is simple to use, yet incorporates cutting edge spectroscopy, machine learning and cloud computing to provide real-time lab-quality results.

“We’ve been working with a mid-sized brewery in the Silicon Valley area to develop the initial product,” Sukuta said. The brewery market is attractive because brewers want to know specific properties of their beer during various parts of the process, which fit perfectly with Brewmetrix’ combination of spectroscopy and computational capability. Chemical properties important to brewers include: apparent extract (PEA), original extract (PEO), percent alcohol content, bitterness (IBU’s), color (Degrees Lovibond), pH, free amino nitrogen (FAN) and yeast viability.

To use the Brewmetrix system, a small sample of the liquid to be tested would be drawn into a cuvette. The top of the shoebox-sized system (shown above) would be opened, and the cuvette placed in a slot inside. Once closed, the system will take the measurements needed to determine a variety of measurements/specifications, upload the data to the cloud- where machine learning is applied to identify and validate the measurements. The results are then relayed, in real-time, to the user’s device, which could be a phone app or email.

Sukuta states that this approach to quality control is much more convenient. “Currently, breweries have to wait hours or days for results,” Sukuta explained. “Using the Brewmetrix system, that time is reduced to minutes.” The benefits of the system, in addition to the convenience, is that batches of brews in large stainless steel vessels can be moved on to the next step in the process faster, without waiting for results and possibly having conditions change during the waiting time. “If you can work with your smartphone, you can work with Brewmetrix, and then this becomes accessible to average person.”

The Brewmetrix product is part black box, part wireless device and part machine learning AI. The actual Bremetrix instrument is the size of a shoebox, with one of StellarNet’s custom OEM spectrometers inside. “As you can tell, we’re not doing standard spectroscopy”, Sukuta said.

So why StellarNet?

Sukuta met StellarNet at a Photonics West show several years ago. He began speaking with the team about the mini rugged spectrometers, and eventually purchased one for the early stages of the Brewmetrix product. Eventually, more spectrometers were purchased as development continued and application-specific needs were identified.

Quality Control in a small to mid-size brewery

Current Method:

  • Brewer takes sample
  • Sends to external lab with chemicals, personnel, equipment
  • Sample gets tested, analyzed
  • Brewer waits for results
  • Results are sent back to the Brewer
  • Time-consuming and expensive

With Brewmetrix:

  • Brewer takes sample
  • Places into Brewmetrix system using StellarNet’s custom OEM spectrometer, data is taken in seconds, sent to cloud for analysis
  • Results are instantaneously sent back to the Brewer’s device(s)
  • Fast, convenient and reliable

“StellarNet has been easy to work with,” Sukuta said. “We’re not doing something standard here, and StellarNet’s team was willing to work with us and our programmers. They’ve customized their product specifically for our application. Their support has been great.”

“We have so much to offer OEM integrators, designers, process managers, and manufacturers,” says David Parrino, StellarNet’s Director of OEM Business Development. “At StellarNet, we are willing to explore new territory with our customers and we don’t require a huge commitment to work with a designer to create something spectacular.

All it takes is a phone call to get things started.” Jason Pierce, VP at StellarNet, agrees. “With over 30 years of in-house design expertise, on-site programmers who specialize in integration with external systems, and our new zAP2 wireless capabilities for any of our spectrometers, StellarNet is a great partner for innovative companies like Brewmetrix.”

Why Spectroscopy?

The idea for Brewmetrix actually came from using spectroscopy to classify skin cancer cells. “That was part of my research,” Sydney said. That chemical free lab-in-a-box idea continued to grow, and eventually grew into the Brewmetrix product. Approximately five years ago, the team started working with breweries to evaluate the product, and use the data obtained to apply for patents. For three years, the company has been acquiring data, tweaking prototypes and validating requirements.

The return-on-investment (ROI) for a brewery using a Brewmetrix system will depend on how many external lab tests are required each month, but for the typical micro-brewery, the cost ROI will likely be less than twelve months. But truly, the most valuable ROI is to never lose a batch of beer to a failure in quality. The larger the production volumes, the higher the stakes are for the brewery. If a brewer can catch something early, they might be able to correct that mistake before it becomes a large investment of ingredients literally poured down the drain.

Brewmetrix is initially offering its product to small- to mid-sized breweries, and is currently recruiting beta-test partners. However, the system can test any liquid, which includes drinking water. Therefore, the next target market for Brewmetrix is the water testing market. “Right now, the company is getting patents and becoming certified with the state of California, like stand-alone chemical labs are currently certified with the state. This will be necessary when the company begins to target water testing applications,” Sukuta concluded.

Interested in the Brewmetrix product?

Brewmetrix plans to begin offering its product to mid-sized breweries beginning in 2019. The first Brewmetrix product should be available by the time of 2019 The American Society of Brewing Chemists in New Orleans, June 24–26, 2019. Brewmetrix is seeking small- to mid-size breweries interested in the Brewmetrix product to participate in initial product rollout before the product is released to the public.
