John - I used D254 in my primary and didn't start the MLF until after pressing. I'd check with WE to see what they say about doing an MLF on this kit. But, if it's an issue at all, I have a gallon bag of PS skins you can have.
That's quite the kind offer, your generosity is much appreciated!! Since they are already thawed, the plan to add the Bravado mix to them this evening will continue, unless WE get back in touch with me and tells me that they put sorbate into the juice during their manufacturing processes.
