United States Pharmacopeia, USP, is the official standard setting authority for medicines, supplements and health care products in the United States. Glycol carrying the USP Grade provides an assurance that the product is approved for Food Applications. Penguin Chillers Propylene Glycol is produced using the highest quality making it perfect for brewing and for use around food or food related products.

Recommended Glycol Mix

We recommend using a 35% – 40% glycol to water mix.   Depending upon the application (desired operating temp/freeze point) you can use any combination of water to glycol mix ratio that you prefer. However, it’s a standard practice for brewing applications to use a 35% to 40% mix ratio.


Mixing Example:

1 Gallon of Glycol + 1.75 Gallon of Water = 2.75gal of 36.3% Glycol Mix.


1 Gallon of Glycol + 1.5 Gallon of Water = 2.5gal of 40% Glycol Mix.
