Your favorite childhood chewing gum says a lot about you, but in adulthood, cartoony packaging and huge bubbles are less of a priority than taste, texture, its ability to keep breath from smelling like pizza, and most importantly, how long the flavor lasts.
To find out which brand lasts longest, we assembled a panel of three experienced gum chewers, each tasked with comparing the mouth-life of 14 different varieties of gum. The times listed are the overall averages, but it's important to note that there was almost no variation between chewers.
Since there's no codified scientific method for judging gum flavor, we decided a stick of gum was finished when all the flavor was transferred from the gum into the mouth, which typically coincided with hardening texture, apathy towards chewing, and eyes wandering towards the underside of nearby desks. Obviously most people chew gum for longer, but our tasters concluded that this is a consequence of residual flavor coating the mouth long after the gum itself becomes a lifeless waste of mouth space.
