This creates a sense of continuity and allows you to tailor the taste and texture according to your preferences. To maintain the culture for future use, it is necessary to practice some simple steps.
After making a batch of yogurt, set aside a small portion (around two tablespoons) as the starter for subsequent batches. Ideally, this should be done before flavoring or adding any sweeteners or fruits to ensure consistency in future batches.
Store the starter in an airtight container in the refrigerator until you are ready to make more yogurt. By consistently saving and reusing this starter, you can create an ongoing supply of delicious homemade yogurt.
Store-bought plain yogurt as a starter
For those who are new to making their own yogurt or don't have access to existing homemade cultures, store-bought plain yogurt can serve as an excellent alternative starter option. However, it is crucial to consider certain factors when choosing store-bought starters. Look for yogurts labeled "live cultures" or "probiotic" on their packaging since these indicate that they contain active bacterial strains necessary for fermentation.
Avoid yogurts with additives such as gelatin, thickeners, or excessive sugar since these can negatively impact the quality and consistency of your homemade yogurt. Several popular brands have gained recognition for producing reliable starters with consistent results.
For example, Fage Total Greek Yogurt has been praised for its rich taste and active cultures. Stonyfield Organic Plain Yogurt is another trusted brand that emphasizes organic ingredients and live cultures.
These brands have built a reputation for their commitment to quality, making them a recommended choice for those seeking reliable store-bought yogurt starters. Remember to check the expiration date and ensure the yogurt is fresh before using it as a starter to maintain the optimal bacteria count for fermentation.

Exploring Alternative Yogurt Starters
Raw milk as a starter culture source
Using raw milk as a starter culture for yogurt making is an intriguing alternative that offers distinct advantages and challenges. One of the primary benefits is the abundance of natural bacteria present in raw milk, which can contribute to the fermentation process and produce a unique flavor profile in homemade yogurt.
The diverse microbial population in raw milk adds complexity and depth to the final product, resulting in a rich and tangy taste that many yogurt enthusiasts appreciate. However, it is important to note that using raw milk as a starter also comes with potential risks.
Raw milk may carry harmful bacteria such as Salmonella or E. coli, which can cause foodborne illnesses if not properly handled or consumed unpasteurized. To mitigate these risks, certain safety precautions should be followed.
If you decide to use raw milk as a starter, ensure it comes from reliable sources with stringent quality control measures. Additionally, pasteurizing the raw milk by heating it to at least 161°F (71°C) for 15 seconds will effectively kill any harmful bacteria while preserving some of the beneficial microorganisms necessary for fermentation.
Probiotic capsules or powders as starters
Probiotic capsules or powders offer another alternative for those seeking to make homemade yogurt without traditional starters. These products contain specific strains of beneficial bacteria known for their probiotic properties, making them suitable candidates for kickstarting the fermentation process.
When selecting probiotic capsules or powders for yogurt making, it is crucial to choose those containing live cultures relevant to yogurt production.
