Mushroom because of its nature will be more compact and provide less volume than a kernel the same size that is butterfly. Think of rolling your clothes when you pack a suitcase vs just fluffing them up and throwing them in. rolling is more compact so will take up less space. The mushroom doesnít have the butterfly branches that take up space and provide the increased volume. If you pop a popping of Mammoth you would get appx 28 CC per gram of popcorn. If Caramel and Sweet, appx 32 CC per gram. If Weaver Gold you would get appx 48 CC per gram. MWVT is volume per weight. So popping it and dumping it in you popper cabinet you would get appx 50% more volume with Weaver Gold vs CS and 70% more than with Mammoth. If they actually scooped it out and put it in containers there is now way Weaver Gold does not provide more volume. Now the kernel size is much bigger with Mammoth and CS than Weaver Gold, so if you looked at a kernel side by side, Weaver Gold is smaller. Remember when you pop 32 oz you will have more kernels in Gold that the others and that contributes to the volume as well as the shape of the kernel. Thatís just popping and dumping. Now it gets tricky. Depending on the coating process, how heavy the coating is and how much the corn is being tossed around etc, you will have more breakage with butterfly and offset that advantage some. Mushroom because it is ball shape wonít have near the breakage. So if they want the "WOWĒ thatís a big kernel, it is Mammoth. If they want most servings per weight, itís Weaver Gold as long as they arenít beating the crap out of the kernels. If they want the most volume per weight with minimal breakage in a coating process then CS is the best. Another option would be LK butterfly. A lot of snack manufacturers use it for Kettle. It is more durable than Weaver Gold and still gives a more tender butterfly flake than mushroom.
