Yogurt has become an integral part of our daily lives, and its versatility has led to an explosion of flavors and types. From Greek yogurt to coconut yogurt, the options are endless. But have you ever wondered what makes yogurt, well, yogurt? The answer lies in the yogurt starter, a crucial component that transforms milk into a creamy, tangy delight. In this article, we’ll delve into the world of yogurt starters, exploring the various options available and how to use them to create your perfect cup of yogurt.
The Science Behind Yogurt Starters
Before we dive into the types of yogurt starters, it’s essential to understand the science behind them. Yogurt is created through a process called fermentation, where microorganisms like bacteria and yeast feed on the lactose in milk, producing lactic acid as a byproduct. This lactic acid is responsible for the characteristic tang and thickness of yogurt.
In traditional yogurt production, a yogurt starter culture is added to the milk, containing the necessary microorganisms to kick-start the fermentation process. These microorganisms, typically Lactobacillus bulgaricus and Streptococcus thermophilus, work in harmony to break down the lactose and create the perfect environment for yogurt to form.
Types of Yogurt Starters
Now that we’ve covered the basics, let’s explore the various types of yogurt starters available:
1. Store-Bought Yogurt Starters
The most common and convenient option is to purchase a yogurt starter from a health food store or online retailer. These starters usually come in the form of a freeze-dried powder or a liquid culture and are specifically designed for home yogurt making. Store-bought starters are a great option for beginners, as they provide a guaranteed outcome and are easy to use.
2. Yogurt from a Previous Batch (Perpetual Starter)
If you’re an avid yogurt maker, you can use a small portion of your previous batch as a starter for the next batch. This method, known as a perpetual starter, allows you to create a continuous cycle of yogurt production. Simply set aside a small amount of your previous batch, store it in the fridge, and use it as the starter for your next batch.
3. Yogurt from a Friend or Online Community
You can also obtain a yogurt starter from a friend who already makes yogurt or from online communities and forums dedicated to yogurt making. This method is an excellent way to get started, as it allows you to tap into the knowledge and experience of others.

What is a yogurt starter?
A yogurt starter is a blend of friendly bacteria, typically Lactobacillus bulgaricus and Streptococcus thermophilus, that is added to milk to ferment it and create yogurt. These bacteria convert the milk sugar (lactose) into lactic acid, thickening the milk and giving it a tangy flavor. Yogurt starters can be found in various forms, including powders, capsules, or even frozen or dehydrated cultures.
Using a yogurt starter allows you to control the type and amount of bacteria in your yogurt, which can be especially beneficial for those with digestive issues or who prefer a particular flavor or texture. Additionally, yogurt starters can be reused multiple times, making them a cost-effective and convenient way to produce your own yogurt at home.
What are the different types of yogurt starters?
There are several types of yogurt starters available, each with its own unique characteristics and benefits. Some common types include thermophilic starters, which are suitable for hot temperatures and produce a thick, creamy yogurt, and mesophilic starters, which thrive in moderate temperatures and produce a thinner, more gel-like yogurt. There are also starters specifically designed for goat’s milk, sheep’s milk, or non-dairy milks, as well as those that are tailored to produce specific flavors or textures.
When choosing a yogurt starter, it’s essential to consider the type of milk you’ll be using, the desired consistency and flavor, and any dietary restrictions or preferences. With so many options available, it’s easy to find a starter that meets your needs and helps you create the perfect yogurt for your taste buds.
How do I store my yogurt starter?
Proper storage is crucial to maintaining the health and potency of your yogurt starter. If you’re using a powdered starter, store it in an airtight container in the refrigerator or freezer to keep it away from light and moisture. For liquid starters, it’s best to store them in the refrigerator and use them within a few days of opening.
