This is one of the traditional ways I learned to make yogurt.
I’ve made yogurt from scratch many times, and when I was in other countries this was one of the methods I was shown: heat the milk, let it cool enough for the live culture, add a spoonful of yogurt as the starter, then let it ferment warm.
That warm fermentation is what allows the cultures to multiply and acidify the milk. And here’s where it gets interesting: different strains behave differently.
Depending on the culture I’m using, I may continue straining it at room temperature for a period of time, because some cultures can continue fermenting and increasing in viable bacteria under the right conditions. If the strain is better suited to a more controlled or cooler environment, I’ll use the refrigerator instead.
The key is that strain, temperature, acidity, and time all matter. More time at room temperature does not automatically mean more beneficial bacteria.
Then as the whey drains out, the yogurt gets thicker — from yogurt, to Greek-style yogurt, to a thick labneh-style spread.
Old-school method, a little microbiology, and a very good reason to make your own. 😉
