We use homegrown non-gmo popcorn and season with all natural, gluten free, and vegan ingredients. There is no butter or cheese! BjornQorn's special flavor comes from nutritional yeast, which is a high protein and high B-vitamin seasoning that is popular in vegan cuisine, but is especially great on popcorn. Our popcorn is popped directly by the heat of the sun. We use enormous mirrored reflectors to collect the sun's rays and focus them on our kettles. On a sunny day, each kettle saves as much electricity as an entire house would use! 3 ounce bag.
