Production Process: Straining vs. Fortification
While both Arla's Skyr and Greek yogurt are fermented dairy products, their paths to a thick, creamy consistency diverge. The core difference lies in how they achieve their final texture.
Greek Yogurt Production
Traditional Greek yogurt is a strained product. After the initial fermentation, the yogurt is placed in cloth bags or passed through filters multiple times to remove the liquid whey. This straining process concentrates the yogurt, resulting in a denser, thicker product with significantly higher protein and lower sugar content. Because more milk is used to produce the same amount of finished yogurt, it tends to be more expensive.
Arla Yogurt Production
Arla produces a variety of yogurts, but its most comparable product to Greek yogurt is Arla® Skyr, an Icelandic-style yogurt. The process for Skyr involves meticulously straining the whey to a greater extent than regular yogurt, much like Greek yogurt, which is why it is also notably thick and protein-rich. However, Arla also produces standard yogurts which are not strained to the same degree, and their 'protein' yogurts are often fortified with extra milk protein rather than being concentrated solely through straining. The Arla website notes their Skyr is made from skimmed milk and is naturally high in protein due to concentration, staying true to traditional methods.
Nutritional Differences
Because of the contrasting manufacturing methods, the nutritional profiles of Greek yogurt and various Arla yogurts are not identical. These differences are particularly pronounced in plain, unflavored varieties.
- Protein: Greek yogurt is celebrated for its high protein content, which is concentrated through straining. Plain Greek yogurt can contain about 15-20 grams of protein per 6-ounce serving. Arla's Skyr is also very high in protein, boasting around 10 grams per 100 grams, comparable to Greek yogurt. However, standard Arla yogurt contains less protein, around 3.5 grams per 100 grams.
- Calcium: In the straining process for Greek yogurt, some calcium is lost along with the whey. As a result, standard Arla yogurt often has more calcium than its Greek counterpart. Arla's protein-fortified yogurts and Skyr still contain calcium, but standard regular yogurt may have an edge for those prioritizing this mineral.
- Fat: Both Greek and Arla yogurts are available in a range of fat percentages, including non-fat, low-fat, and full-fat. Arla's Skyr is traditionally made from skim milk and is naturally fat-free, while Greek yogurt can use different milk types.
- Carbohydrates and Sugar: Due to the straining process that removes some lactose, plain Greek yogurt typically has lower carbohydrate and sugar content than regular yogurt. Plain Arla Skyr, also strained, will follow this trend, but flavored versions of both brands will have added sugars.
Taste and Texture Comparison
The production methods directly impact the final sensory experience of each yogurt.
- Texture: Greek yogurt is famously thick, dense, and creamy due to the concentration of milk solids. Arla's Skyr matches this dense consistency, often described as similar to a thick Greek yogurt. In contrast, a standard, non-strained Arla yogurt is much thinner and smoother in texture.
- Flavor: Greek yogurt has a distinct, tangy, and slightly sour flavor profile. Arla's Skyr offers a similarly tangy taste, which is characteristic of fermented products. Standard Arla yogurt, with its higher lactose content, is milder and often has a slightly sweeter taste.
Which Yogurt is Right for You?
Choosing between Arla yogurt and Greek yogurt depends on your specific nutritional needs, flavor preferences, and culinary applications. Here is a helpful guide to consider:
- For High Protein: If your primary goal is to increase protein intake for muscle building or satiety, Greek yogurt or Arla Skyr are excellent choices.
- For Higher Calcium: If you are prioritizing calcium intake, a standard, unstrained Arla yogurt will typically provide more per serving.
- For Lower Sugar: Both plain Greek yogurt and plain Arla Skyr have naturally lower sugar content than their standard or flavored counterparts, making them good options for managing blood sugar.
- For Cooking and Dips: The thick, dense texture of Greek yogurt and Arla Skyr makes them ideal substitutes for sour cream or mayonnaise in recipes, dips, and sauces.
- For a Milder Taste: If you prefer a less tangy flavor, a standard, non-strained Arla yogurt is a better fit.

Final Conclusion
Ultimately, the choice between Arla yogurt and Greek yogurt boils down to a few key factors: texture preference, nutritional goals, and price point. For those seeking maximum protein and a very thick, tangy texture, both Arla's Skyr and Greek yogurt are excellent, highly comparable choices. Greek yogurt may offer slightly more protein per serving depending on the brand, but Arla Skyr provides a similar experience, often at a competitive price. However, if your health priority is a higher calcium intake or a less tangy, milder flavor, a standard, non-strained Arla yogurt would be the better option. Both types offer valuable probiotics for gut health, provided you select varieties with live and active cultures. The best advice is to always read the nutritional information on the label and choose a plain, unflavored variety to avoid unnecessary added sugars, sweetening it yourself with fruit or a touch of honey if desired.
How the Environmental Impact Differs
The environmental footprint of yogurt production varies, particularly concerning the volume of milk required. Due to the straining process that removes excess whey, producing Greek yogurt and Arla Skyr requires significantly more milk than standard yogurt. This higher milk demand means a larger agricultural footprint per serving for these concentrated products. Some of the liquid whey strained from Greek yogurt can be a source of waste if not handled properly, though many companies now find ways to utilize it, for example, in animal feed.
For consumers concerned with environmental impact, this could be a deciding factor. However, many brands, including Arla, have made strides in sustainable dairy farming, so it's worth exploring a company's specific environmental practices rather than making a blanket assumption based solely on the product type.

Storage and Shelf Life
Both Greek and Arla yogurts require refrigeration to maintain freshness and preserve their active cultures. However, their thick textures can impact how they are stored and used. The dense nature of Greek yogurt and Arla Skyr makes them less prone to separation than standard yogurt, which can become watery over time. Always check the 'best by' date on the packaging, and once opened, consume the yogurt within a few days for the best quality and flavor.
Additives and Sweeteners
Consumers should be mindful of added ingredients in both Arla and Greek yogurt products. While plain versions are simple, flavored yogurts can be loaded with added sugars, artificial flavorings, and thickeners. Opting for plain yogurt and adding your own fruits or natural sweeteners like honey allows for better control over sugar intake. Some brands of Greek-style yogurt, as opposed to traditional Greek yogurt, may use thickeners to mimic the strained texture, so checking ingredient lists is important. Arla's products, like their protein yogurts, may also contain thickeners and sweeteners.
Uses in Cooking and Baking
The varying textures and flavors of Greek and Arla yogurts lend themselves to different culinary applications. Greek yogurt and Arla Skyr, with their thick, creamy consistency and tangy taste, are perfect for:
- Tzatziki sauce and other creamy dips.
- Marinades for tenderizing meat.
- Substitutes for sour cream or mayonnaise.
- Adding richness to smoothies.
Standard Arla yogurt, being thinner and milder, is better suited for:
- Creating lighter, smoother salad dressings.
- Mixing into baked goods for moisture.
- Use in smoothies where a lighter consistency is desired.
Ultimately, the choice comes down to the desired outcome of the recipe, whether it's a thick, creamy sauce or a light, refreshing drink.
Understanding 'Greek-Style' vs. True Greek Yogurt
It is also important to differentiate between authentic Greek yogurt and products labeled 'Greek-style'. True Greek yogurt is strained, but Greek-style versions may use thickeners to achieve a similar texture without the concentration process. This can impact the protein content, which is a key nutritional advantage of genuine strained yogurt. When comparing products, be sure to check the ingredient list and label to understand if it is a truly strained product or a 'Greek-style' alternative.
What are Probiotics in Yogurt?
Probiotics are live bacteria cultures added during fermentation that can benefit gut health. Most Greek and Arla yogurts contain these beneficial bacteria, but their potency and specific strains can vary. To ensure you're getting the best probiotic benefits, look for labels that explicitly state 'live and active cultures'. The fermentation process, for both types, also enhances nutrient absorption and makes the yogurt easier to digest for many individuals.
Conclusion: Making the Right Choice
Both Arla and Greek yogurt offer valuable nutrition and versatility in the kitchen. For those prioritizing high protein and a thick texture for dips and sauces, Arla's Skyr is a direct competitor to traditional Greek yogurt. However, if bone-strengthening calcium is a bigger priority and you prefer a milder flavor, a standard Arla yogurt may be a better fit. As with any food, the best choice is often a plain, unsweetened version to maximize health benefits and control sugar intake. Understanding the different production methods—straining versus fortification—will help you make an informed decision based on your personal health goals and taste preferences.
