Process: Milk Processing

What is Low-Temp, Vat Pasteurized?

Hartzler’s Dairy uses a low-temperature vat pasteurization method. This ensures our milk retains a majority of its enzymes, which are crucial for proper digestion and good health.

Pasteurization of commercially-sold milk is required by the U.S. Food and Drug Administration to ensure that harmful bacteria in milk is eliminated. Standard pasteurization methods utilize high-heat, high-volume methods that unfortunately kill beneficial enzymes as well as bacteria. Some milk is even ultra-pasteurized to the point that it can be stored without being refrigerated. Some in the dairy and health industries refer to ultra-pasteurized milk as “dead milk” because everything -- harmful and beneficial - have been killed

What is Non-homogenized?

While most milk undergoes homogenization, ours does not.  Homogenization was developed simply to give milk a balanced consistency, eliminating the need to shake it before drinking. Milk in its natural state has a cream layer that floats to the top.

Anyone who grew up on a farm, or before homogenization was common, will tell you that the cream gives milk a clean, full-bodied flavor and is the most desirable part! We tend to agree.

Package: Why Glass Bottles Matter

Hartzler's Glass Milk Bottles

While some folks love the nostalgia of our glass bottles and seeing the cream line at the top, there are actually some very important reasons why our milk is sold in glass bottles.

The first is that it prevents the absorption of unwanted chemicals from seeping into your milk. Most plastic bottles and jugs leak measurable amounts of chemicals into the liquid they contain. (Please refer to the sources below.)

The thick glass bottles we use also keep milk cooler, adding to its freshness.

And last, but by no means least, our philosophy of doing things “as nature intended” also applies to the way we treat the earth. Instead of further adding to landfills, we collect, sanitize and reuse our 1/2-gallon glass bottles. You only need to return them to any location that sells Hartzler Milk, and you’ll receive a deposit and the bottles will be picked up by our drivers to take back to our plant and reused.
