Greek yogurt's signature thick, creamy texture and high protein content come from a deliberate process that removes most of the liquid, or whey, from regular yogurt. It is therefore not made *with* whey, but rather, is a product created by removing it.

Greek yogurt undergoes a straining process that removes most of the liquid whey. While regular yogurt contains both whey and casein, the extensive straining primarily removes the liquid whey, leaving behind a product with a higher concentration of casein protein.

Greek culinary tradition reveals that authentic yogurt is not always made from cow's milk, with traditional village recipes using nutrient-rich sheep's milk. While most supermarket Greek yogurts are cow-based, genuine versions often rely on the milk of sheep and goats, which roam the rugged terrain of Greece.

According to industry data, over 90% of all yogurt consumed worldwide falls into two main categories: set and stirred. The main processing steps in the manufacture of set and stirred yogurt are similar initially, but diverge critically during the incubation phase, a difference that directly impacts the final product’s texture and consistency.

According to food scientists, the primary distinction between stirred yogurt and other forms is its post-fermentation processing. Understanding what's the difference between stirred yogurt and yogurt primarily comes down to whether it was stirred before or after incubation, a seemingly small step that creates very different textures and culinary applications.

For every container of commercial yogurt sold, the production process begins with milk that has been thoroughly pasteurized. This means that yes, the milk base for your vanilla yogurt is pasteurized, a crucial and standard step for ensuring food safety and product consistency.

According to food science, all Greek yogurt is a form of fermented yogurt, but not all fermented yogurt is Greek yogurt. This distinction lies in a single, important production step that dramatically impacts the final product's texture, taste, and nutritional profile.

The vast majority of commercial and traditional yogurts rely on a symbiotic starter culture consisting of two key bacteria: *Streptococcus thermophilus* and *Lactobacillus delbrueckii subsp. bulgaricus*. This co-culture is essential for initiating fermentation, which transforms milk into the creamy, tangy product we know as yogurt.

Around 70% of the world's population is lactose intolerant to some degree, making the fermentation process central to dairy consumption for many. This remarkable biochemical process explains how does Lactobacillus convert milk to yogurt, transforming simple milk into a complex, tangy food rich with beneficial bacteria through a controlled series of reactions.

Over 621 million kilograms of yogurt were produced using *Streptococcus thermophilus* in 1998, a testament to its critical role in the dairy industry. This specific strain of *Streptococcus* is deliberately included in yogurt for its vital role in fermentation, contributing to the product's characteristic texture and tangy flavor, as well as providing potential health benefits.
