Starting the week with a handful of coffee - Espresso m&m's

Coffee and chocolate go together like peanut butter and jelly. The combination is a no-brainer, which must be why m&m's keeps revisiting it. 

We've had: 

• Pumpkin Spice latte m&m's - review
• Coffee Nut m&m's
• Crunchy Espresso m&m's - review
• Café Mocha m&m's - review
• Caramel Cold Brew m&m's 

And now these. What makes these any different from it's predecessors?
