I've purchased and used that all grape pack once before. 9 lbs I think it was. Very convenient. But definitely not dried. No different than a skins pack from a kit (which is what it is, just sold separately)
There is something called CabernetZyn by RayZyn on Amazon which claims to be dried Cabernet grapes. Reviewers complain of seeds and stems so it might be better for winemaking than snacking. They also offer Merlot and Chardonnay, also chocolate covered. Not sure those would be good. Kind of pricey, but might work if you really want some dried grapes.
In the past I have purchased the All Grape pack mentioned above from the finevinewines site.
Thanks so much for your posts on tweeting cheap kits, Joeswine. I have enjoyed them very much and tried several of your techniques with very pleasing results.
