Aha! I've been sampling some Bluniverse and I know where the bite comes from - it's the pineapple! Ms Universe has a lot of Pineapple in it, along with the Kali Mist. So it's a blueberry taste with a pineapple backbite.
The jar smells amazing!
Too bad it doesn't give you the buzz you were looking for. I agree the smells and taste from her were excellent. The 1 I grew was more Indica than I expected but it was still worth running again.
