Why Do Mini M&M's Taste Different Than Regular Ones?

First released in 1941 as a heat-resistant treat for WWII soldiers, M&M's have grown into a cultural icon — with roughly 400 million produced daily in the U.S. From being requested by NASA crews as the first candy in space to expanding into flavors like strawberry shake, mint, and pretzel, this brand has been constantly evolving. But the introduction of M&M's Minis in 1997 didn't just add a new size of candy-coated goodness; it created an entirely new sensory experience for chocolate-lovers all over the world. 

Have you ever wondered why these tinier candy counterparts taste even sweeter than their original creations? Well, the answer to why these M&M's minis taste different lies in your tastebuds and the tiny candies' candy shell-coated surface. According to the National Science Foundation (NSF) Center for Sustainable Nanotechnology, mini M&M's owe their heightened sweetness entirely to their structural geometry and surface area, rather than added sugar.

When you pop a handful of the smaller candies into your mouth, their diminished size creates a higher surface-area-to-volume ratio compared to standard-sized M&M's. Even though a serving of these tiny candies contains roughly the same mass of sugar and caloric value as their larger counterparts, this small difference changes how your tongue's taste buds interact with the confection. And because of this maximized exterior area, your tongue comes into contact with a much greater portion of the candy-coated shell at once. 

This tricks your taste buds into registering a more concentrated sweet flavor right away, creating the illusion of a sweeter experience — despite the ingredients being practically identical. Evidently, with M&M's Minis, you are getting much more than just a one-note chocolatey bite. Ultimately, the science proves that when it comes to intensifying flavor perception, size (and surface area) truly matters just as much as what is on the inside.

While you can simply snack on these candies straight from the bag, mini M&M's can be used for a variety of different purposes. Try adding these to your ice cream sundaes for a satisfying crunch! Or maybe use them in our soft batch mini M&M's chocolate chip cookies. Whether you gravitate towards the classic size or the mini version, next time you stop by your local grocery store, why don't you buy a bag of each and try to taste the difference?
