Could be from an old bug that allowed players to steal certain items that would then retain odd names and/or colors. There are also various graphics for grapes depending on where they came from, ie. the Thanksgiving Cornucopia has several unique graphics for items received by clicking it. If memory serves correct, there are also certain items with unique graphics held inside locked boxes/chests in town shops. The grapes may have come from a lockpicked chest in an inn or food shop. The top right bunch looks like grapes of wraiths, when they 1st came out if you stole them they would lose their original tags to be replaced with the normal “grape bunch” tag. Then again, I could be wrong on all suggestions but thats all I got
