The Meaning of Milk Label Colors
As Paul Michael pointed out in his post Breaking the Bread Code: How to Get the Freshest Loaf, the plastic tabs on bread have meaning, and the colors are fairly standardized within the bread-making industry.
But what about milk?
We all know that different types of milk — from skim milk to whole milk and everything in-between — have colored caps and labels so you can tell them apart easily while you’re shopping. What you might not know, however, is that there is no standardized system among dairies that calls for a certain type of milk to receive a specific color.

Almost unanimously, the color for whole milk caps and labels is red — aside from a few rogue dairies that choose shades of orange or brown — which, light research suggests, is the result of do-as-the-Romans-do-type mentality. I looked up how the red cap started and why it is the preferred color chosen by most dairies, but there’s virtually no authoritative evidence.
The same thinking is also applied to 2% milk. Many dairies (but not all, by far) choose a variant of blue — from light to dark — to signify that the milk contains less fat but that it’s not low fat.
1% and skim milk is where the non-standardized system gets tricky. eHow claims that green is the color of choice of most dairies for 1% milk, while skim milk generally receives a purple cap. Except that’s not always the case — not even close. In fact, the 1% milk in my fridge, from Market Pantry (a Target brand), is yellow.
He compiled the milk-cap colors for the four most popular milk types — skim, 1%, 2%, and whole — from 33 popular dairies. As I mentioned, most of the whole milk caps were red, but lessen the fat content in the milk and a seemingly random rainbow of colors appear. There’s 2% with a red cap from Mayfield (which uses brown for whole milk), a purple cap for 1% from Alta Dena, and a green cap for skim from Sunnyside.
What’s even more interesting is that some brands — like Trader Joe’s — don’t distinguish their organic and non-organic skim milks — both receive a light blue cap — which can be deceiving to shoppers, especially those in a hurry.
In addition, Brenneman even offers to help standardize the colors using this system:
- Red Cap: Whole Milk
- Purple Cap: Reduced-Fat (2%) Milk
- Green: Low-Fat (1%) Milk
- Light Blue: Skim Milk
- Brown Cap: Chocolate Milk
- Pink Cap: Strawberry Milk
- Yellow Cap: Buttermilk
- Orange Cap: Half and Half
- Magenta Cap: Whipping Cream
Seems like a well thought-out solution, considering that many dairies are already on board with these colors choices for the various types of milk.
With such a seemingly easy problem to solve, why hasn’t it been standardized yet?
