Mars Wrigley Confectionery has launched a second Flavor Vote campaign, asking M&M’S lovers to choose from three crunchy possibilities.

The new flavors — Crunchy Espresso, Crunchy Raspberry and Crunchy Mint — appeared at select retailers this week and will go nationwide April 1.  Fans can purchase and try each new flavor and cast a vote for their favorite once a day until May 25.

In August, Mars Wrigley will announce the winner, which will appear on shelves for 18 months afterward.

Mars Wrigley launched the first Flavor Vote in 2016 in honor of the M&M’S brand’s 75th anniversary. With more than one million votes submitted, fans selected Coffee Nut as their favorite peanut flavor, joining Original Peanut.

"We wanted to engage our fans once again by empowering them to help decide the next crunchy flavor of M&M'S," says Allison Miazga-Bedrick, M&M'S brand director. "We selected three new decadent flavors we believe our fans will enjoy, as they reflect the on-trend, unique and bold tastes growing in popularity across the U.S."

Each new flavor is made with dark chocolate and wrapped in M&M'S signature colorful crispy shell. The Crunchy Raspberry variety features a regular rice crisp center, and the Crunchy Espresso and Crunchy Mint varieties feature a cocoa rice crisp center.

Fans can vote by uploading or taking a "selfie" at flavorvote.mms.com, adding stickers to the image representing their favorite flavor and submitting to the website. They can also share their reactions on social media with hashtags #VoteCrunchyEspresso, #VoteCrunchyRaspberry or #VoteCrunchyMint. The brand's camera-shy fans can simply select their favorite flavor on the website to submit a vote or text the word "VOTE" to 84444.
