I want to make some of this banana wine, but I cannot find any golden raisins that contain no preservatives or sulfites. I know it will be a while before I need them, but don't want to get a batch going and cannot find the raisins. Can anyone direct me to where I can find/order them at? Everything I've looked at on Amazon has preservatives or sulfites. Also, I'm relatively new at winemaking, so could someone tell me what a grain bag is (Yooper's original post says "Put into grain-bag, tie top,.....)? Is this the same thing as a nylon jelly straining bag? Thanks in advance!
