I decided to give Rachel's yogurt another try today. I figured that I'd give it a fairer shake by doing several things differently.
1. I bought something with a flavor name, instead of an "essence".
2. I searched for something with the furthest out possible expiration date.
3. I kept it colder, to prevent texture issues from slight warming.
I have concluded that this is a thinner yogurt than I tend to eat. I don't think it's too runny when cold, but even slight warming makes it too thin for my taste. I prefer something closer to a custard than a smoothie. It is also much more sour than I like. This time I got a mango, pineapple, passion fruit blend and I could tell that it was tasty, but it was just too sour for me personally. I don't even eat candy that's very sour. I will eat cherry sours and lemon drops, but not anything that most candy eaters would consider a "sour" candy (warheads, sourpatch kids, strips with sour powder whatever those are called).
So I give up, and I won't be buying anymore of that yogurt. They have interesting sounding flavors, and pretty packaging. If you like sour yogurt then you should give them a try, just be ready for a bit of a pucker.
