I just opened a Meg. Amarone kit I am going to start and it came with the grape pack and the raisins. The instructions say to use one or the other but not both. I am assumuting the grape pack is the way to go but when I look at the grape pack, it is identical to the one I received with my Merlot kit. Does it matter what grapes are used as I would think the generic grape pack would change the taste of the Amarone to whatever grapes were used to make the grape pack? I hope I got my concern across. Thanks.
