The Oatly Production Process: Enzyme Power
The sweetness found in many of Oatly's oat milks is a direct result of their unique production method. The process starts with a simple blend of water and oats. From there, the magic happens thanks to naturally occurring enzymes, specifically amylase.
During production, amylase enzymes are introduced to the oat and water mixture. These enzymes function similarly to those in our own digestive systems, breaking down complex carbohydrates and starches found in the oats into simpler sugars, such as maltose. It is this enzymatic breakdown, or hydrolysis, that creates the sweet, milky flavor profile that many people enjoy in store-bought oat milk. This is a critical step that also helps prevent the final product from having a slimy, starchy texture, a common issue with some homemade oat milk recipes. The manufacturer then heats the mixture to deactivate the enzymes, preventing further saccharification.
Labeling Standards: A Tale of Two Regions
One of the most confusing aspects of oat milk's sugar content is how it is labeled, which can differ significantly depending on the country. For example, in the United States, FDA guidelines require that any sugar created during processing through controlled hydrolysis, like Oatly's, must be declared as "Added Sugars" on the nutrition label.
In contrast, many European markets consider this sugar a byproduct of the oat, meaning it is not always labeled as an 'added sugar'. This discrepancy explains why a consumer might see two different labels for the exact same product depending on where they buy it. It's important to read the nutrition facts panel carefully and understand the labeling rules of your region. Oatly is transparent about this process, explaining that the sugars are a product of the oats themselves, not something they are intentionally adding for sweetness.
Sweetness Comparison Across Oatly Varieties
Not all Oatly products have the same amount of sugar, offering different options for various preferences and dietary needs. The sweetness level can depend on the specific formulation and how extensively the enzymatic process is carried out.
- Oatly Original Oat Milk: A popular choice, this version contains approximately 7 grams of total sugars per serving, all derived from the enzymatic process.
- Oatly Full-Fat Oat Milk: Similar to the original, the full-fat version also contains around 7 grams of total sugars per serving.
- Oatly Low-Fat Oat Milk: This variety also contains about 7 grams of total sugars per serving, but with a lower overall fat content.
- Oatly Unsweetened Oat Milk: This product is specifically engineered to have less sugar. Oatly's food scientists have developed a method to reduce the maltose content, resulting in 0g of total sugars on the nutrition label.
- Flavored Oat Milks (like Chocolate): As expected, these versions contain added sweeteners in addition to the naturally derived oat sugars, so you can expect a higher total sugar content.
How Oat Milk Sugar Compares to Dairy Milk
It's a common point of discussion whether the sugar in oat milk is higher or lower than cow's milk. A comparison can help put the numbers into perspective.
| Feature | Oatly Original Oat Milk | Semi-Skimmed Cow's Milk | Comparison | , | 
|---|---|---|---|---|
| Total Sugars | ~7g per 240ml serving | ~12g per 240ml serving | Oatly contains less total sugar. | |
| Sugar Source | Enzymatically-produced from oat starch | Lactose (naturally occurring) | Different sugar types and sources. | |
| Added Sugars (US Label) | 7g | 0g | FDA rules differ for processing. | 
From a nutritional standpoint, the sugar in standard Oatly products is slightly lower than the lactose in cow's milk. The key difference is the source: one is a result of oat starch breakdown, while the other is a naturally occurring milk sugar (lactose).
Conclusion
Yes, there is sugar in Oatly oat milk, and it's a planned outcome of the manufacturing process. By using natural enzymes, the starches in the oats are converted into simpler sugars, creating the sweet taste and creamy texture consumers enjoy. While Oatly does not add sweeteners to its plain varieties, different countries' labeling regulations may cause this naturally derived sugar to be listed as "added sugar" on packaging. For those watching their sugar intake, the Unsweetened version is an excellent option with zero grams of sugar. Understanding this enzymatic process allows consumers to make informed choices based on their dietary needs and preferences.
Making Homemade Oat Milk: Avoiding the Enzymes
If you prefer to control the level of sweetness and avoid the enzymatic conversion of starch to sugar, making your own oat milk is a straightforward alternative. The key is to minimize the soaking and blending time to prevent the oats' starches from breaking down. A common mistake is over-blending or using warm water, which can activate the enzymes and result in a slimy, sweet liquid. For a less sweet product, use cold water and blend for just 30-60 seconds before straining thoroughly through a nut milk bag. You can then add natural sweeteners like dates if desired, giving you complete control over the final flavor.

Frequently Asked Questions
1. Does Oatly add sugar to its plain oat milk? No, Oatly does not add cane sugar or other sweeteners to its unflavored oat milk varieties. The sugar comes from the oats themselves through an enzymatic process.
2. Why is sugar sometimes labeled as 'added sugar' on Oatly packaging? This depends on the country. In the US, FDA regulations require that sugars created during controlled hydrolysis, which Oatly uses, be listed as 'Added Sugars'. In other regions, like Europe, it is categorized differently.
3. How much sugar is in a glass of Oatly Original oat milk? A 1-cup (240ml) serving of Oatly Original oat milk typically contains 7 grams of total sugars, which is the amount listed as 'added sugars' on the US label.
4. Is the sugar in oat milk unhealthy? The sugar in oat milk is primarily maltose, which has a high glycemic index and can cause a blood sugar spike, but whether it is 'unhealthy' depends on your overall diet and consumption. For most people in moderation, it's not a concern, especially when compared to cow's milk which has a similar sugar content.
5. Does Oatly have a sugar-free option? Yes, Oatly offers an Unsweetened oat milk version. This product is specifically manufactured to have 0g of total sugars per serving.
6. How is the sugar content reduced in Oatly Unsweetened? Oatly's food scientists have developed a special process for their Unsweetened variety that reduces the amount of maltose created during the enzymatic breakdown of the oats.
7. How can I avoid the sugar in store-bought oat milk? To completely avoid the sugar produced through enzymatic processing, you can either purchase Oatly's Unsweetened product or make your own oat milk at home, ensuring you use cold water and minimal blending to prevent the enzymatic process.
