A canning line unexpectedly stops during a packaging run. A conveyor bearing fails after weeks of daily washdowns. An auditor asks for documentation on every lubricant used throughout your facility.
None of these problems starts with the beer—they start with the equipment behind it.
From brewhouses and fermentation tanks to packaging lines and glycol cooling systems, breweries depend on properly lubricated equipment to keep production running safely and efficiently. Choosing the right food-grade lubricant helps reduce the risk of contamination, extend equipment life, support food safety programs, and minimize costly downtime.
Whether you operate a growing craft brewery or a large-scale production facility, understanding where food-grade lubricants are used—and how to choose the right one—is an important part of protecting both your equipment and your product.
In this guide, we'll cover:
Food-grade lubricants are specially formulated oils, greases, and fluids designed for equipment used in food and beverage manufacturing. Unlike conventional industrial lubricants, they're made with ingredients approved for environments where accidental food contact may occur.
For breweries, the most important distinction is between NSF H1 and H2 lubricants.
| Classification: | Where It's Used: | Food Contact: |
| H1 Lubricants | Processing and packaging equipment | Incidental contact permitted |
| H2 Lubricants | Maintenance areas away from production | No food contact permitted |
Because breweries frequently operate around open product, packaging materials, and washdown environments, H1 lubricants are typically the appropriate choice anywhere incidental contact is possible. They help support food safety while protecting equipment from wear, corrosion, and premature failure.
Different areas of the brewery place different demands on equipment—and the lubricants that protect it.
Let's walk through the brewing process and explore the most common applications for food-grade lubricants and fluids.
After boiling, wort must be cooled quickly before fermentation begins. Plate heat exchangers and glycol cooling systems play a critical role in this process.
NSF-certified food-grade propylene glycol is commonly used in these closed-loop cooling systems because it provides efficient heat transfer while helping protect against corrosion and freezing.
As yeast converts sugars into alcohol, fermentation naturally generates heat. Glycol jacket systems circulate chilled food-grade propylene glycol around fermentation tanks to maintain consistent temperatures and protect beer quality.
Packaging equipment often operates continuously and is cleaned regularly with water and sanitizing chemicals.
Common lubrication points include:
These applications benefit from H1 lubricants that offer excellent water resistance, corrosion protection, and long service life.
Many breweries also use food-grade propylene glycol in cold storage rooms and long-draw draft systems to maintain serving temperatures and protect cooling equipment.
While every brewery has unique equipment, the table below provides a quick reference for common lubrication and cooling applications.
| Brewery Area: | Equipment: | Recommended Product: |
| Wort Production | Plate heat exchanger | NSF food-grade propylene glycol |
| Wort Transfer | Plate heat exchanger | H1 food-grade oil |
| Fermentation | Glycol jacket systems | NSF food-grade propylene glycol |
| Packaging | Conveyor chains | H1 chain lubricant |
| Packaging | Bearings | H1 grease |
| Packaging | Gearboxes | Food-grade gear oil |
| Packaging | Fillers & cappers | H1 lubricant |
| Cold Storage | Chillers & circulation systems | NSF food-grade propylene glycol |
| Draft Systems | Long-draw glycol systems | NSF food-grade propylene glycol |
Not every food-grade lubricant is designed for the same application.
The best choice depends on your equipment, operating environment, maintenance schedule, and food safety requirements. Selecting the right lubricant starts with understanding how and where your equipment operates.
Before purchasing a lubricant, ask these four questions.
If a lubricant could accidentally contact beer, ingredients, or packaging materials, choose an NSF H1 lubricant.
When in doubt, H1 is the safest choice for brewery production equipment.
Frequent sanitation removes lubrication over time.
Equipment exposed to water and cleaning chemicals benefits from lubricants with strong water resistance, corrosion protection, and good adhesion to metal surfaces.
Different applications require different performance characteristics.
Consider:
Matching the lubricant to the application helps maximize equipment life and reduce maintenance.
Always verify the recommended viscosity, lubricant type, and maintenance intervals for your equipment.
A lubricant that performs well in one application may not be appropriate for another.
| Expert Tip: Standardizing H1 lubricants across similar equipment can simplify maintenance, reduce inventory, minimize misapplication, and streamline food safety audits. |
Food-grade lubricants aren't the only fluids that help keep brewery equipment operating efficiently. Many breweries also rely on NSF-certified food-grade propylene glycol in glycol chillers, fermentation jackets, cold storage systems, and long-draw draft lines.
Unlike industrial glycol formulations, food-grade propylene glycol is specifically designed for food and beverage applications where incidental contact could occur. It helps maintain consistent process temperatures while providing reliable heat transfer, freeze protection, and corrosion resistance for closed-loop cooling systems.
Using the proper glycol concentration is just as important as selecting the right product.
Too little glycol can leave your system vulnerable to freezing, while too much can increase viscosity, forcing pumps to work harder and reducing heat-transfer efficiency.
Although every system should follow the equipment manufacturer's recommendations, many breweries operate with glycol concentrations around 35–40%. A good rule of thumb is to maintain a solution with a freeze point approximately 20–25°F below the chiller set point to help protect the system without sacrificing cooling performance. Regularly checking glycol concentration with a refractometer is a simple preventive maintenance step that can help verify system performance before problems develop.

Even experienced maintenance teams can make lubrication mistakes that affect equipment reliability.
Always use H1 lubricants where incidental food contact is possible.
Repeated cleaning removes lubrication and increases the need for relubrication.
Cooling systems should use NSF-certified food-grade propylene glycol—not industrial formulations.
Routine inspections and proper lubricant selection help prevent costly equipment failures before they interrupt production.

Most brewery production equipment should use NSF H1 food-grade lubricants because incidental food contact is possible.
H1 lubricants are approved for incidental food contact, while H2 lubricants may only be used where food contact is impossible.
No. Brewery cooling systems should use NSF-certified food-grade propylene glycol designed for food and beverage applications.
It depends on the equipment, operating conditions, and washdown frequency. Always follow manufacturer recommendations while adjusting intervals based on your operating environment.
It helps regulate temperatures in glycol cooling systems while providing freeze protection and corrosion resistance in food-processing environments.
Many breweries reduce complexity by standardizing H1 lubricants across similar equipment wherever practical, making maintenance and inventory management easier.
Sometimes, but not always. While many breweries standardize on compatible H1 lubricants to simplify maintenance and inventory, different equipment may require specific viscosities or formulations. Always follow the equipment manufacturer's recommendations and consult your lubricant supplier when consolidating products.
