yes it does leave unpopped kernels
not all of the kernels pop in popcorn bags but the best so far Orville reddenbocker.
Popcorn pops based on the moisture content held inside the kernel and yes does vary by brand, age of the kernels and storage times.
Different bags mean different ages and storage places. They could of been made with different things and older things. All popcorn bags are different might have less kernels or less unpopped kernels when u cook it. I am doing a science fair project and I'm doing it on, "Does the different brands of popcorn affect the total of unpopped kernels?" I have a lot of info that you can see above. You think there is no a lot of info but go to Google and type in, "does different types of popcorn affect the total of unpopped kernels and look. One thing that makes a difference is amount of popcorn in the bag, how much time you put it in for, and the most important is INGREDIENTS. This girl did something like this and she said palm oil makes a difference. The smallest things make the biggest differences.
Pop Secret
It depends on how long you pop the bag in the microwave.
