DURHAM — Precision Fermentation of Durham has more money coming in. According to an SEC filing from earlier this week, the company has raised $6,076,274 of equity from a single investor.

The company’s focus is on the use of IoT (internet of things) technology to more accurately measure the conditions inside fermentation tanks. The BrewIQ system allows for custom alerts and data to help inform trends impacting output and consistency – critical to the beer industry. The technology can also be used in other fermentation industries such as distilled spirits, dairy, kombucha, and bio-ethanol.

Precision Fermentation last raised $2 million from two investors in March of this year. In June, the U.S. Patent and Trademark Office awarded the company two patents related to the “instrumentation, monitoring, and analysis of commercial fermentations.” Jared Resnick, the company’s founder and CEO, spoke about the complexities in the official press release.

“Fermentation is not a straight-line process; fluid density and volumes of dissolved gasses change with the progression of biological activity. These changes in turn impact sensor accuracy and make precision measurements with static individual sensors difficult. Our patented approach to fermentation monitoring uses multiple sensors and optimizes sampling timing and process, and then applies machine learning to the readings, ensuring accurate and timely measurements throughout each stage of the fermentation cycle.”

In total, the company has now raised more than $12.5 million since 2020.
