Yep I think the word "style" is a work around that tells you it is not real. We get our Greek Yoghurt from a non commercial dairy who have now expanded and become commercial due to it's popularity. You can definitely taste the difference between fake and genuine.
I think genuine Greek yogurt tastes pretty awful. But it is good substitute for Ranch or sour cream and that is why I use it. I will mix it with fruit and oats sometimes as well but that is just to fill my belly... i never crave it.
If I am going to suffer though something that I don't really like the taste of because of the nutritional elements of it, I will become really angry if someone duped me and filled up that space with sugars and other chemicals. I will never forgive this brand.
I only use it as a marinade on chicken fillets along with some other ingredients. Plain yoghurt on it's own is terrible and guess honey would be the obvious choice most people add to it.
