Cornucopia appears to be another of the Paklab brands. They are not listed (that I could see) at the Paklab web-site. There was not much info available, and I have never seen them in the stores.
Except for the ports, sherries, and icewines under this name at one site, they all appeared to be like the Island Mist brand, so presumably have an f-pac containing sweetener and fruit flavouring.
