Lol.. The parents have more than just grape names.. Grape is in the "lineage" of both parents. And fact is, there is no such thing as identical in the world of autos. Similar, yes.. Same, no.. Also "lime" or citrus, is one of the most common terp profiles in all of cannabis.. Lime/citrus is as common as a cell phone. So naming a strain "fill in the blank" lime, and saying that every plant smells or tastes like lime isn't saying much.. Specific flavors on the other hand, grape, coffee, rootbeer, etc are hard to lock down in an auto. Keep in mind that when breeding autos, there is no way to smoke or test the flowers of the mother plants before they are pollinated.. So breeders don't know what the mother tastes like until after it's seeded and harvested. You can only select a plant to pollinate based on what you see and smell, and then hope for the best. Grape Stomper Og, the mom of sour stomper, is one of the most grape dominate tasting and smelling strains in the photo period world, and was found and hunted by one of the most respected breeders to ever hunt strains. So again, the grape smell and taste is in the "lineage" of couple grape.. It will show up... but how often that pheno shows up, to me, is unknown. Could be 1 in 4.. Could be higher.
