October Newsletter | CO2 Purity and Quality
CO2 Quality for Brewing
CO2 quality is as essential as any other utility and ingredient. CO2 influences beer’s sensory profile, foam, mouthfeel, and stability, all important to the drinking experience. Understanding the impact of CO2 purity in the final product is crucial, especially as suppliers diversify sources due to market demand.
With craft-scale CO2 recovery technology, small breweries can eliminate reliance on this volatile market and ensure consistent, high-purity CO2 that goes above beverage-grade standards.
Difference Between Beverage-Grade and Food-Grade CO2
The primary difference is in the specific testing standards and purity requirements they must meet, as set by regulatory bodies like the U.S. Pharmacopeia (USP), the Food and Drug Administration (FDA), and the European Commission (EC).
Food-Grade CO2 is tested with strict standards to ensure it is safe for food processing, storage, and transportation, while focusing on eliminating contaminants like heavy metals, pesticides, and microbiological impurities that could affect food safety.
Beverage-Grade CO2 must meet purity standards that prevent off-flavors, odors, or impurities that could impact the taste and appearance of beverages. The FDA also regulates this grade in the US, allowing up to 0.09% of other hydrocarbons.
Both grades are high-purity gases, but they undergo different testing and quality checks to match their intended purpose, whether that’s preserving food safety or ensuring beverage quality.
Manage CO2 Purity in the Brewery
Work Closely with Suppliers
Establish regular communication to verify that your CO2 meets purity standards. Request a Certificate of Analysis (COA) with each delivery to confirm quality.
Audit Supplier Practices
Periodically audit your supplier’s quality management and purity testing protocols to ensure they meet industry standards, ideally through independent ISO-certified labs.
Inspect Delivery Systems
In bulk deliveries, inquire about the maintenance of delivery trucks to avoid cross-contamination with non-beverage-grade CO2. In the brewery, maintaining CO2 storage and handling systems, like preventing condensation in gas lines, is also key to quality.
With a reliable CO2 recovery system in place, breweries can achieve the necessary high-quality standards right in their own brewery, while securing independence from an unpredictable CO2 market. It’s an investment that not only secures quality but also reduces operational costs, offsets carbon emissions, and offers brewers control over their own CO2 source.

MBAA Philadelphia District Technical Weekend
On November 2nd, former Master Brewers President Jaime Jurado will be speaking at the DISTRICT PHILADELPHIA MASTER BREWERS ASSOCIATION OF THE AMERICA Fall Technical Weekend at Yards Brewing Co.
With over 40 years of experience as a brewery engineer and expertise in sustainability and brewing technologies, Jaime will cover different aspects of CO2 recovery for breweries looking to reduce waste, lower carbon footprint, and improve operational efficiency. From scaling and calculating CO2 needs to understanding the potential for recovering CO2 through fermentation, Jaime’s seminar will give valuable insights for craft breweries of all sizes.
Circular Carbon Capture in the Drinks Industry Webinar
Zero Waste Scotland held a webinar on circular carbon capture in the beverage industry, featuring Steve Stewart from Stewart Brewing to talk about his experience with the implementation of CO2 recovery in the brewery. Before CO2 recovery, they were releasing 70 tons of CO2/yr into the atmosphere, but now with the DALUM CO2 Recovery Plant, they’re able to capture 45 tons of 99.99 % pure, odorless, and tasteless CO2, while only needing 35 tons for their operation. Implementing this technology has improved efficiency, job satisfaction, business resilience, and made it possible for them to save money for future investments. Watch the webinar and hear more from Steve on why he and his wife, Jo, thought that CO2 recovery falls part of their entire philosophy towards net zero, and how the brewery is coping with the challenges of global change:
