The Tribest yogurt maker is a quality product with mostly good reviews every where you look. The great benefit of making your own yogurt is that you know the good bacteria within your homemade yogurt are alive.
When you make yogurt with the Tribest electric yogurt maker you don't need the Life and Active seal (which is a great idea for store bought yogurt) because the very fact that your milk or soy milk has turned into yogurt PROVES that the yogurt bacteria are alive and well.
Yolife Yogurt Starter contains 4 different bacteria.
The 2 standard starter bacteria, Lactobacillus bulgaricus and Streptococcus thermophilus as well as Bifidobacterium longum and Lactobacillus acidophilus.
It is a non-dairy starter so that you can use it if you're vegan or want to make yogurt from soy milk.
I'm struggling to find any! I did see one person unhappy with the temperature, but if it is too high, the good bacteria that make the yogurt die, and most users are very happy with their yogurt so obviously this doesn't happen normally.
Yolife tell you what bacteria they use in the starter, but not which strain they are. They're not alone in this - none of the yogurt makers I have reviewed do - but simply stating that a yogurt contains Lactobacillus acidophilus, for example, is not sufficient nowadays. However as most of us don't eat enough of the lactic acid producing bacteria and their starter does contain that, this is a minor point.
Overall, the Yolife yogurt maker is a quality product.
