McDonald’s is making two big changes to its menu that will affect burger customers across the country.

The company announced that it will roll out two new iterations of its signature Big Mac, one bigger and one smaller than the original. In addition, the company confirmed to Business Insider that it has discontinued its “Create Your Taste” customizable burger platform, which allowed customers in select cities to build their own burgers on touch-screen kiosks.

Big Mac fans will soon have new options to choose from on the McDonald’s menu. The Grand Mac and Mac Jr. will join the signature Big Mac roster for a limited time on McDonald’s national menu in early 2017.

The Grand Mac is made with two 100 percent pure beef patties for a total of one-third pound with two slices of American cheese and iconic special sauce served on a larger sesame seed bun with lettuce, California minced onions, and pickles. Each Big Mac patty is seasoned with salt and pepper in McDonald’s kitchens.

The Mac Jr. is a single-layer Big Mac that’s easier to eat on the go. The 100 percent pure beef patty is bigger and packs in all the flavor of the Big Mac but without the middle bun.

“The Big Mac is a legend and a great-tasting burger with hints of pickle relish, mustard, garlic, and onions,” says McDonald’s chef Mike Haracz. “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.”

Earlier this year, Central Ohio and Dallas/Fort Worth tested these burgers to gather valuable feedback from consumers. In advance of the national rollout, customers in Florida and the Pittsburgh area will be able to experience these new sandwiches before the rest of the country, beginning in mid-November.

Meanwhile, the company is pulling the plug on the “Create Your Taste” platform, which has been tested in several locations since 2014, and which the company announced last year would expand to 2,000 locations nationwide. “Create Your Taste” allowed customers to assemble their burgers on large touch-screen kiosks, choosing from dozens of ingredients, and then to have the burgers brought out to their tables.

A company spokeswoman told Business Insider that “Create Your Taste” would be replaced by “Signature Crafted Recipes,” which will similarly give customers an opportunity to customize their burgers, but with fewer options.
