Simply Nature Organic Grassfed Milk

Aldi offers a range of milk options, ranging from whole to 2%, to chocolate, and even organic and grass fed. Aldi’s Simply Nature Organic Grass Fed Milk caught my eye recently, and I decided to give it a try.

Simply Nature Organic Grassfed Milk

It sells for $4.19 for a 64-oz. or half-gallon carton, or 6.5 cents per fluid ounce, but I got mine on sale for $3.49, or 5.5 cents per fluid ounce. The grass fed milk is a Regular Buy, meaning it should always be on store shelves. For comparison, Horizon Organic Milk, sold at Walmart and other stores, is about 7 cents per fluid ounce.

The milk is reduced fat, containing 2% fat, or 30% less fat than whole milk, according to the carton. The carton states the milk contains Vitamins A and D and is Grade A, homogenized, ultra pasteurized, and comes from cows fed a grain-free diet.

The carton also states: “Why try Simply Nature Organic Grassfed Milk? The diet of a dairy cow counts! Grassfed, grain free diets, straight from lavish green pastures.”

The carton displays a small seal from Validus Verification Services indicating that the producer received an Animal Welfare Review Certification. Certification includes meeting requirements on proper animal handling and management, herd health procedures and care, food and water quality standards, and housing that promotes animal comfort and cleanliness.

The side of the Simply Nature Organic Grass Fed Milk carton also states: “Simply Nature is proud that the farms that produce our organic milk are Validus Certified. Validus is a USDA Process-Verified program for animal welfare certification.”

My family didn’t have any complaints about the taste of Aldi’s Simply Nature Organic Grass Fed Milk, although my husband (who likes milk) thought it had a slightly different taste — with grassy notes — compared to conventional milk. Also, the carton stated the milk was good for about a month and a half from the date when I purchased it, which seemed like a long time to me, but it also said it was best to consume the milk within seven days after opening the carton.

Is Grass Fed Milk Healthier?

Science shows that there are some benefits to drinking milk from grass fed cows rather than grain fed cows.

The American Dairy Association states that milk that comes from grass-fed cows has more healthy fats such as CLA or conjugated linoleic acid and an Omega-3 fat called alpha-linoleic acid. The University of Minnesota Extension says another type of fat called linoleic acid, which is an Omega-6 fat and has been linked to cardiovascular disease, diabetes, and obesity, shows up in lower amounts in pasture-fed cow’s milk as well.

Where is Aldi’s Grass Fed Milk From?

The carton doesn’t say who produces this milk or where it came from, but I visited the website Where Is My Milk From? and entered the carton’s code numbers. It told me Aldi’s grass fed milk is from Aurora Organic Dairy in Platteville, Colorado. Aurora Organic Dairy is a large factory farm with more than 15,000 cows. (According to The Washington Post, that’s about 100 times the size of a typical organic herd.) Aurora has also supplied milk for brands sold at Walmart, Costco, and Target.

Aurora Organic Dairy has come under criticism for not following organic milk production standards. In May of 2017, The Washington Post wrote an investigative piece about Aurora titled “Why Your ‘Organic’ Milk May Not Be Organic”. They visited the farm several times in 2016 and never saw more than 10% percent of the cows grazing outdoors at any one time. They saw the same trend when consulting satellite photos of the farm.

The Washington Post also had a dairy science professor from Virginia Tech evaluate samples of milk from eight farms or companies, some organic and some not, including Aurora Organic Dairy. According to their tests, Aurora’s organic milk tested like conventional grocery store milk with lower levels of CLA and linoleic acid, the healthier components of organic milk. It did not have the numbers associated with organic milk.

The Cornucopia Institute, a nonprofit whose mission is “promoting economic justice for family scale farming,” maintains a scorecard on major dairy producers. In its scorecard for Aldi’s Simply Nature milk, it confirms that Aldi’s organic milk comes from Aurora Organic Dairy, “the largest factory-organic dairy producer in the USA,” and it states that “10 years ago, USDA inspectors found Aurora in ‘willful’ violation of the law, including illegally bringing in conventional cattle and confining cows without grazing.” Aldi was scored low by the Institute in large part because it did not respond to the Institute’s request for information.

What About Other Grocers?

Aldi isn’t the only store singled out by the Cornucopia Institute. The Institute points out that none of the private-label store brands they contacted participated in their dairy survey and scorecard program. Other store brand milk that receives a low rating on their scorecard includes Trader Joe’s, Kroger’s Simple Truth, Meijer Organics, Costco’s Kirkland Signature, and Walmart’s Great Value. A common thread is transparency, as few grocers seemed inclined to respond to the Institute’s request for information.

Horizon Organic, a large-scale organic farm operation with products sold at both our local Walmart and our local Target, also scored low in large part because it did not respond to the Institute. Horizon has, like Aurora Organic, been criticized for its practices.

The Cornucopia Institute argues that private-label organic products are “buyer beware,” and they recommend that consumers contact stores to confirm where their milk is coming from or buy name-brand milk from brands that are more transparent. It notes that while customers who buy organic products like to know where their food comes from, private-label products “often obscure these facts.”

The Verdict:

Aldi’s Simply Nature Organic Grassfed Milk is advertised as coming from cows fed a grain-free diet, and it tastes fine. It’s also cheaper than a lot of other similarly labeled grassfed organic milk. There are, however, a lot of questions about Aldi’s supplier: Aurora Organic Dairy is a large factory farm that has come under criticism several times in the past decade for allegedly not following standards for organic milk production.

Aldi is by no means the only grocer whose organic milk supply line is in question, but it still leaves us concerned. After all, if we’re going to pay extra for milk that is marketed as organic and grassfed, we want to make sure that the cows in question are actually raised in the way the packaging suggests. We can’t ultimately say what consumers should do, except to arm themselves with the best information they can.

  1. This is good info. I’d like to find an organization, grass-fed milk option that is affordable and actually practices what they claim. Too bad this isn’t that option. Kind of makes me wonder about Aldi’s organic, cage free eggs as well, which we frequently buy.

  2. I have small question that how it is possible for very long shelf life of organic milk. Which kind of preservatives are added?

    • There are no preservatives listed among the ingredients. It’s specially sealed, which helps it to last if the container hasn’t yet been opened. However, you do have to use it within a week once opened.

  3. Thank you for this thoughtful post! I’m a milk fanatic. Also lived in Switzerland where cows regularly eat grass. The health benefits are profound. Anyway, grass fed cow’s milk in the United States is often not organic and this is actually a good thing. Dean foods (the biggest milk producer and producer of Horizon Organic) lobbied the government to say that if cows are outside they cannot be organic because the rain is not organic and neither is the grass. So what most of us would consider natural and grass fed cows are rarely organic. Instead the word “organic” is usually for cows fed organic corn in stalls (not good). If you want grass fed milk check a local dairy and don’t stress on the “organic”, and ask how they raise their cows. Organic Valley is also one of the only major brands which does have high standards and somehow manages to make it organic, but it’s often $8.99 for a 1/2 gallon. And unfortunately Organic Valley is not at Aldi.

  4. Comment on milk cartons.
    Why can’t Aldi (and others) use the old-style, waxed cartons that have no plastic lid. They worked very well and did not contribute plastic bits for birds to eat (and die from). Just pry the carton top open with your two thumbs and fold the spout out. More ingenious than the current ones, with add-on plastic spout.

  5. Nothing on the label says ultra pasteurized that I can tell…. Would like the definitive word on this if anyone can help please.

    • If you click on the photo of the nutrition information in this post, it states toward the bottom of the carton that it’s ultra pasteurized.

  6. This milk might be a limited-time Aldi Find now. It’s in the weekly Aldi ad for May 29th, 2024.
