What is

shelf-stable
milk?

It’s real milk you can store in the pantry, thanks to airtight, no-light packaging.

Shelf-stable vs. refrigerated milk

Horizon shelf-stable and refrigerated milk are both organic. Both are real milk. Both are delicious. What makes shelf-stable different is how it’s pasteurized and packaged. With higher temperature pasteurization and special packaging, shelf-stable milk can be stored safely without refrigeration. Never run out of Horizon again—just stock the pantry with shelf-stable. Always use it by the best-by date and store it in the fridge after opening.


UHT pasteurization

Pasteurization is the process we use to help eliminate bacteria in milk. The process for shelf-stable milk is called UHT pasteurization, or Ultra High Temperature. Milk is heated to a very high temperature for just a few seconds, which destroys bacteria for a longer shelf life.


Packaging

Special packaging, along with UHT pasteurization, is the key to shelf-stable milk. We use Tetra Pak® cartons that lock in nutrition and great taste and lock out air and light. Be sure to follow the recycling instructions on the packaging. Many of the recycled cartons get a second life as paper products and building materials.


Single-serves

Our single-serve milk boxes are also shelf-stable, so you can store them in the pantry and take them anywhere—for lunches, for travel, at sports practice or to the park. A Horizon milk box delivers 8 grams of protein and a good source of calcium, along with the goodness of real organic milk.
