I was on the EB Repo and went to a cooking demo and the Chef said it would be sold at Epcot. Im sure you can purchase it during Food and Wine Festival.
If you cannot find it close to home, try Rosa Regale by Banfi. I went to a demo at FWF a few years back and everyone fell in love with it and was buying it by the case.
Magicale tastes the same and the Chef onboard did mention Rosa Regale to the audience if they could not find Magicale to pair with the dessert offering.
