The available flavors take a page from their potato chip flavors with Maple Bacon, Salt & Fresh Ground Pepper, Sea Salt, Sriracha, and White Cheddar available. Of the five, only White Cheddar is not verified as non-GMO by the Non-GMO Project.
Kettle Brand Popcorn is available at select stores starting this summer in 5-oz bags with a suggested retail price of $3.69 per bag. It's not yet searchable via their online product locator so you might just have to keep an eye out or call around.
