It’s important to note that while the Noris milk bottled in glass jars is non-homogenized, Noris also produces and distributes a homogenized milk (only available in one-gallon plastic jugs) under the label, ‘Organic Life’.

This appears to be a move to help keep the business afloat by offering a product that more closely resembles supermarket fare. This being said, the Organic Life milk is still low-heat pasteurized, so it only stays fresh for about seven days. What’s more, the Organic Life milk comes from the same cows living the same great Noris Dairy life that few cows will ever experience.

In addition to the glass jugs, our family often also buys a gallon of the Organic Life milk solely for mom and dad’s mocha habit. Homogenized milk tends to produce better microfoam (http://en.wikipedia.org/wiki/Microfoam) for mochas and lattes. I believe this is because the fat molecules are more evenly distributed throughout the milk when it’s homogenized –compared to its non-homogenized sister, which lets the milk separate naturally.

If you have a decent espresso machine that can produce microfoam (few can), you’ll certainly notice the difference. Professional machines like the La Marzoccos used by Stumptown Coffee (and others) produce perfect microfoam with homogenized milk, and nearly perfect microfoam with non-homogenized milk (as long as the barista knows what they’re doing).

Our Gaggia Espresso Pure machine produced terrible microfoam out of the box, but a simple move of the o-ring gasket on the steam wand turned it into a pretty decent microfoam producer (likely the best you’ll get for $250).

My point is this: Noris glass jar milk is non-homogenized and delivered in its perfectly natural, low-pasteurized state. The one-gallon plastic jugs feature a homogenized version of the same perfectly natural, low-pasteurized milk. Pick your poison, you won’t be dissatisfied.
