For the past 40 years, the Big Mac has perhaps been the most recognizable item on the McDonald’s menu. Still, earlier this year, a report alleged that four-out-of-five millennials had never eaten the iconic burger, and now the Golden Arches could be tweaking the item to appeal to a wider audience.

According to Business Insider, McDonald's announced this week that it will soon be releasing two new Big Mac sizes—the “Grand Mac” and the “Mac Jr.”—at locations across the country. Though McDonald's has been testing the miniature and XL burgers at select restaurants for sometime, the new, nationwide release will begin in early-2017.

Over the years, McDonald’s has added a plethora of new items and innovations, but for decades the Big Mac has been seen as sacrosanct. Now the company will allow customers to play the role of Goldilocks, choosing between the single-patty Mac Jr., or a Grand Mac with 66 percent more beef and an extra slice of cheese sandwiched between an over-sized sesame seed bun.

"The Big Mac is a legend and a great-tasting burger with hints of pickle relish, mustard, garlic and onions," Mike Haracz, a manager of culinary innovation at McDonald’s, said in a statement. "We listened to our customers who told us they wanted different ways to enjoy the one-of-a-kind Big Mac taste. The classic combination of ingredients remains timeless and customers around the world continue to enjoy its signature taste."

Though customers will have to wait a couple months to sink their teeth into that Grand Mac (come one, who’s going to order a Mac Jr. when you can have two-thirds more beef in your mouth?), McDonald’s is clearly willing to do whatever it takes to get people excited about it’s classic burger again.
