Years ago there was a thread on HBT complaining about a company selling kits to make sparking wine with 100% fruit juice from the store. It got heated real quick. I'll link the thread if I can find it.
Letting it condition with some of the lees was a bad idea. Sucker geysered as soon as I popped the cap of.
I made some with cranapple and Nottingham that I let ferment to about 1.005 and bottled in a champagne bottle for the fizz. Wasn't half bad honestly.
