What is Greek Yogurt?

Greek yogurt is a popular type of yogurt. Greek yogurt has a thick consistency and is less sweet compared to other types of yogurt.

Though making Greek yogurt or any general yogurt remains the same, there are additional steps in making Greek yogurt that provides it with a thick consistency, unlike regular yogurt.

Firstly the milk is fermented to change the lactose in milk to lactic acid. The bacteria used for its fermentation are Streptococcus thermophiles and Lactobacillus bulgaricus.

These bacteria help in the coagulation of milk. Further, this mixture is passed through a mesh cloth, and the excess liquid is separated from the coagulated milk.

This process is traditionally repeated mostly three times to give the yogurt a thick consistency, and this is the process that separates Greek yogurt from any regular yogurt.

Greek yogurt hence requires more milk than regular yogurts. Greek yogurt is famous for its fluffy and soft texture. Nowadays, it is in high demand among health-conscious people as it has several health benefits and is less in calories. On average, 100 grams of Greek yogurt has 133 calories.
