Yogurt is a staple in many kitchens, enjoyed for its creamy texture, versatility and nutritional value. But walk down the supermarket dairy aisle and you'll find plenty of options, including regular yogurt, Greek yogurt and Greek-style yogurt. So, what exactly is the difference between regular yogurt and Greek yogurt, and which one should you choose?
While both are made through the fermentation of milk using live bacterial cultures, the biggest difference comes down to one simple step: straining.
Let's explore how they're made, how their nutritional profiles compare and why both can be a valuable addition to a balanced diet.
How Is Regular Yogurt Made?
Regular yogurt is made by fermenting milk with specific live bacterial cultures.
During fermentation, these bacteria consume lactose, the naturally occurring sugar in milk, and produce lactic acid. As acidity increases, milk proteins coagulate, giving yogurt its characteristic thickened texture and slightly tangy flavour.
Once fermentation is complete, regular yogurt is cooled and packaged without removing the whey. This gives it a softer, smoother and often more pourable consistency.
Regular yogurt is available in a variety of fat levels, flavours and textures, making it a versatile ingredient for breakfast, smoothies, baking and everyday meals.
How Is Greek Yogurt Made?
Greek yogurt begins in much the same way as regular yogurt. Milk is heated, cooled and inoculated with live yogurt cultures before being left to ferment.
The difference happens after fermentation.
Greek yogurt is strained to remove some of the liquid whey, leaving behind a thicker, denser yogurt with a naturally creamy consistency.
Because some of the liquid is removed, the remaining yogurt becomes more concentrated. This means Greek yogurt typically contains more protein per 100g than regular yogurt, although the exact nutritional content depends on the milk and manufacturing process.
The longer the yogurt is strained, the thicker it becomes. This is what gives Greek yogurt its distinctive consistency and makes it particularly popular for breakfast bowls, dips, sauces and high-protein meals.
Regular Yogurt vs Greek Yogurt: What's the Difference?
Although both products are fermented dairy foods, there are some notable differences.
1. Protein content
Greek yogurt generally contains more protein per 100g than regular yogurt because straining concentrates the milk solids and removes some of the liquid whey.
Protein contributes to muscle maintenance and growth, supports tissue repair and helps keep you feeling satisfied after eating.
This makes Greek yogurt a popular choice for people looking to increase their daily protein intake.
2. Texture and consistency
Regular yogurt has a softer, smoother consistency and is often easier to pour.
Greek yogurt is thicker, denser and creamier because much of the liquid whey has been removed during straining.
3. Carbohydrates and lactose
Greek yogurt often contains less lactose and fewer carbohydrates per 100g than regular yogurt because some of the whey, which contains lactose, is removed during straining.
However, Greek yogurt is not necessarily lactose-free. The amount remaining varies depending on the milk, cultures and straining process.
4. Fat content
Neither type of yogurt is automatically higher or lower in fat. The fat content depends primarily on the milk used.
Both regular and Greek yogurt are available in full-fat, reduced-fat and fat-free varieties.
5. Taste
Regular yogurt generally has a mild, slightly tangy flavour.
Greek yogurt tends to have a richer, more concentrated tanginess, with a creamy mouthfeel that makes it particularly versatile in both sweet and savoury recipes.
Which Is Better for Gut Health?
Both regular and Greek yogurt can contribute to a healthy diet and provide beneficial live microorganisms when they contain active cultures.
The bacteria used to ferment yogurt convert lactose into lactic acid, creating the characteristic flavour and texture while changing the composition of the milk.
However, not all yogurts contain the same bacterial strains or quantities of live microorganisms. Some commercial products are heat-treated after fermentation, which reduces or eliminates their live cultures.
If you're choosing yogurt for its live cultures, look for products that clearly identify live or active cultures and have not been heat-treated after fermentation.
It's also worth remembering that more protein or a thicker consistency does not automatically mean a yogurt is better for your gut. Both regular and Greek yogurt can be nutritious choices.
Can You Make Greek Yogurt at Home?
Absolutely! In fact, making Greek yogurt at home is surprisingly simple.
All you need is fresh milk and an active yogurt starter culture.
Once your milk has fermented and developed a set consistency, simply chill it and strain it through a fine cloth, cheesecloth or nut milk bag to remove the whey.
The longer you strain it, the thicker your yogurt becomes. You can even adjust the consistency to suit your preferences, from a soft, creamy Greek-style yogurt to an extra-thick consistency.
With a live starter culture, you can also use a portion of your previous batch to inoculate your next batch, making homemade yogurt an ongoing kitchen ritual.
At Symbiota, we love bringing traditional fermentation methods into modern kitchens. Our Greek Yogurt Starter Culture makes it easy to get started, giving you the opportunity to create fresh, creamy yogurt at home using your choice of milk.
So, Which Should You Choose?
Ultimately, both regular yogurt and Greek yogurt have a place in a balanced diet.
Regular yogurt is a versatile, everyday fermented food with a softer consistency, while Greek yogurt offers a thicker texture and generally higher protein content per serving.
If you're looking for a convenient way to increase your protein intake, Greek yogurt is an excellent option. If you prefer something lighter and more pourable, regular yogurt may be more suitable.
Greek yogurt is traditionally fermented using the same two primary bacterial species found in conventional yogurt:
-
Lactobacillus delbrueckii subsp. bulgaricus (formerly known as Lactobacillus bulgaricus)
-
Streptococcus thermophilus
These are the two classic thermophilic yogurt starter bacteria. They work together in a process called symbiotic fermentation, where each organism supports the growth and activity of the other.
