After knowing where your yogurt came from and how it is made, Let us find out the different types of yogurt.

Greek Yogurt
Greek yogurt has a higher protein content than other yogurts because the manufacturer drains the whey liquid from the yogurt, resulting in a thicker texture. Greek yogurt is made from the milk of cows, sheep or goats. Greek yogurt is called Greek because the original thicker yogurts were made in Greece. It is sweeter than American and European yogurts.

Liquid or Yogurt Beverages
Commonly known as smoothies, it is almost the consistency of a milkshake. The liquid yogurt contains the health benefits of fiber and any vitamins the fruit contains. The yogurt contains calcium and beneficial bacterial from the live cultures in the yogurt. They are available in most grocery stores among the other types of yogurts. In addition, they can easily be made at home in a blender or food processor with plain yogurt and the desired fruit.

Regular Yogurt
Yogurt made from regular milk contains the most fat, at least 3.5 percent milk fat by industry standards, according to AboutYogurt.com. There aren't any additional flavorings added, so plain yogurt is what original yogurt actually tastes like.

Custard
Custard yogurts generally are the ones that come with fruit already mixed in the yogurt cup. They are also known as French- or Swiss-style yogurts. Yogurt in its purest form has a thin and silky texture--except for the Greek kind. Custard yogurts have additives in them that are labeled as natural, but this does not mean they are naturally in the yogurt. Yogurts that have been thickened into a pudding or custard form and have added flavorings and fruit were created in order to better market yogurt to the general public.

Frozen
Frozen yogurt is frequently chosen by dieters as a healthier alternative to ice cream. It is available in soft- and hard-serve types. Freezing does not kill the bacteria cultures but some manufacturers use heat-treated yogurt or non-fermented milk. A frozen yogurt product with active cultures will provide the same health benefits as in traditional yogurt, but the consumer should also check the sugar, fat and calorie content before selecting a product.
Now you know the different types of yogurt, you can now experiment and try them all.
