Updated August 1, 2019. The vegan Burger King Impossible Whopper is about to go nationwide. Starting August 8, the meat-free Whopper will roll out to every Burger King in the U.S., CNN reports. The burger -- developed in collaboration with Bay Area vegan startup Impossible Foods -- was first available at 59 locations around St. Louis, Missouri. The restaurant said the test went "exceedingly well." According to Cnet, more than one hundred stores across San Francisco, California received the fast food giant's new plant-based option last June. The meat-free Whopper was then made available Miami, Florida; Montgomery, Alabama; Baltimore, Maryland; Las Vegas, Nevada; and Columbus, Georgia are also now offering the meat-free Whopper. Burger King plans to roll out the Impossible Whopper across the chain\u2019s more than 7,000 locations nationwide by the end of the year. But the chain hasn't yet decided if it will be a permanent addition. Chris Finazzo, Burger King's president for the Americas, told CNN Business that they will monitor its sales for a few months before making a decision. "We very much believe in the category," he said, noting that the Impossible Whopper brought new customers and those who haven't visited in a long time to the restaurant. Will the Impossible Whopper Launch In Other Countries? There are reports that Burger King may soon launch its vegan Whopper in the UK. According to The Caterer, the chain is exploring meatless options based on the Whopper's success in the U.S. \u201cFollowing the launch of our meat-free whopper trial in the U.S., we know there is a huge appetite for alternative options to meat here in the UK. We are currently exploring opportunities to bring a meat-free burger to the UK," said a Burger King spokesperson. Burger King also told Narcity that the new plant-based burger "will likely come to Canada" sometime later this year. While no date for Burger King Canada has been announced, the recent announcement that the Impossible Whopper will roll out to all U.S. locations could mean a launch in Canada is imminent. In a video published by CNET, editor Brian Cooley says that although the burger is \u201cthe Tesla of food,\u201d it hasn\u2019t been \u201cwidely available... until now.\u201d The new menu addition includes Impossible Food\u2019s Impossible Burger 2.0, the latest iteration of the burger, which responds "better" than the original Impossible Burger in a restaurant environment, holding up to various preparation methods. According to the video, the new Impossible Burger is able to withstand \u201cthe death-defying drop at the end of ," and it was this factor that eventually convinced Burger King to launch the product. https:\/\/www.youtube.com\/watch?vN9FED3jkNTo April Fool's Day Launch Pat Brown, CEO of Impossible Foods, confirmed that although the announcement landed on April Fool\u2019s Day, the launch is real. He said, \u201cyou can think of it as a \u2018meta\u2019 April Fool\u2019s Joke.\u201d He explained, \u201cpeople will get a burger that they will actually believe it\u2019s made from an animal, and be told it\u2019s made from plants, and think it\u2019s an April Fool\u2019s joke and it\u2019s not!\u201d Upon trying the burger, Cooley admits \u201cwhat\u2019s so good about it, is how unremarkable it is. It\u2019s just like a whopper." The launch marks a change in the chain\u2019s operating methods. The New York Times notes that the new menu option is the result of an unlikely pairing between a business that \u201cpromotes its devotion to beef on every Whopper wrapper (\u201c100% Beef With No Fillers\u201d) and a start-up that is committed to getting people to stop eating beef.\u201d The publication also reports that despite the success of other partnerships between plant-based burger brands and restaurant chains, a national rollout of the Impossible Whopper would mark the largest of its kind in the U.S. The new burger also received praise from the Deputy Prime Minister of Singapore Tharman Shanmugaratnam. \u201cI\u2019ve tried the \u2018Impossible Burger\u2019, and it\u2019s actually very tasty\u201d, he wrote on his Facebook page. \u201cThis can indeed become a big deal,\u201d he continued as he quoted a section of a Vox article on the burger launch. \u201cThis is a huge deal for those who want to see meat alternatives replace actual meat because of concerns over animal cruelty or climate change. If this scales up, it could help save hundreds of thousands of animals from suffering on factory farms, and it could fight global warming by reducing the number of methane-producing cattle. It could also combat other problems like antibiotic resistance.\u201d Is the Impossible Whopper Burger King's First and Only Vegan Option? This new Impossible Whopper isn't Burger King's first foray into offering a meatless option. The chain currently features a MorningStar Farms vegetarian burger on its menu. The patty isn't currently vegan-friendly, however, Kellogg-owned MorningStar Farms has announced all of its patties will be vegan by 2021. This could mean that, in two years time, Burger King could have at least two plant-based burger options on the menu. Several other items offered by Burger King are vegan, including its French Toast Sticks, Dutch Apple Pie, Garden Side Salad, Oatmeal, Hash Browns, and French Fries. Impossible Foods' Mission Through partnerships with major restaurant chains, Impossible Foods is on a mission to transform the global food system. The brand wants to show people that they can still enjoy the taste of meat, without the need for animal agriculture, and the destructive impact it has on both the environment and our health. \u201cWe\u2019ve been eating meat since we lived in caves,\u201d the company\u2019s website notes. \u201cAnd today, some of our most magical moments together happen around meat: weekend barbecues. Midnight fast-food runs. Taco Tuesdays. Hot dogs at the ballpark. Those moments are special, and we never want them to end. But using animals to make meat is a prehistoric and destructive technology.\u201d Using plants to make meat, on the other hand, is progressive, notes Impossible Foods. One Impossible Burger requires half the land of a traditional beef burger, one-quarter of the water, and produces one-eighth of the greenhouse gas emissions. The patty is so environmentally-friendly, it has even been acknowledged by the United Nations. In September 2018, Impossible Foods and competitor Beyond Meat were both awarded the title of \u201cChampions of the Earth\u201d by the UN. \u201cFor their pioneering work towards reducing our dependence on animal-based foods, Ethan Brown and O\u2019Reilly Brown have been selected 2018 Champions of the Earth in the category of science and innovation,\u201d the UN said in a statement. It\u2019s not just the UN who believes in the company\u2019s mission, consumers are on board too. According to Eater, the company had sold more than 13 million burgers by the end of 2018. Impossible Burger 2.0 The brand's original Impossible Burgers were made with textured wheat protein, coconut oil, and potato protein among a variety of other plant-based ingredients. Its latest product, the Impossible Burger 2.0, is a new and improved recipe, made with soy protein concentrate, coconut oil, and sunflower oil. According to Impossible Foods, the second edition of its patty is even "juicier and taster" than its predecessor; it's also more versatile and contains the same amount of iron and protein as traditional ground beef.\u00a0 The magic ingredient to both the original Impossible Burger and the Impossible Burger 2.0 is known as \u201cheme,\u201d aka soy leghemoglobin. The Heme Controversy According to Impossible Foods, \u201cheme is found in every living being -- both plants and animals,\u201d and it\u2019s this ingredient that makes \u201cmeat taste like meat.\u201d The brand\u2019s heme is made via yeast fermentation and has been FDA-approved, but it doesn\u2019t come without controversy. Impossible Foods felt that testing its heme on rats would make a difference in earning the brand major successful distribution approvals -- cue backlash and outrage from the vegan community. Pat Brown -- Impossible Food's CEO and founder -- justified the decision by weighing up the negative consequences of animal testing against the huge ethical advantages of achieving Impossible Foods' end goal: eliminating the need for factory farming billions of animals with widespread distribution of its realistic plant-based meat. \u201cWe were confronted with an agonizing dilemma: we knew from our research that heme is absolutely essential to the sensory experience meat lovers crave,\u201d Brown wrote in a statement in 2017, which acknowledged and attempted to justify the brand's use of animal testing.\u00a0 \u201cReplacing animals in the diets of meat lovers would absolutely require heme," he continued. "So without the rat testing, our mission and the future of billions of animals whose future depends on its success was thwarted. We chose the least objectionable of the two choices available to us.\u201d He concluded, "nobody is more committed or working harder to eliminate exploitation of animals than Impossible Foods,"\u00a0adding that he felt avoiding the animal testing dilemma was not an option for the brand. "We made the choice that anyone who sincerely cares about reducing suffering and exploitation of animals should make,"\u00a0he said.\u00a0"We hope we will never have to face such a choice again, but choosing the option that advances the greater good is more important to us than ideological purity." Fast Food Chains Embrace Vegan Food Impossible Foods isn\u2019t alone in its goal of dismantling the food system and building a new sustainable, ethical future. It\u2019s joined by consumers who are ready for change, some are driven by the environment, some by animal welfare, and others by their own health. These shifting attitudes are in turn having an impact on America\u2019s fast food industry. Before Burger King, White Castle partnered with Impossible Foods. After a successful initial trial period last year, Impossible Sliders are now available in all of White Castle\u2019s 377 restaurants. Customers have embraced the new menu addition. Magazine writer Peter Economy said\u00a0 about the Impossible Slider, \u201cthe Impossible Burger didn\u2019t just look, smell, and feel like a burger, it tasted like one too. I don\u2019t mean \u2018sort of\u2019 or \u2018kind of\u2019 tasted like a burger -- I mean it really did taste like a real, cow-based burger. If this is the future of fast food, then count me in.\u201d Fast food giant McDonald\u2019s has also embraced the vegan movement earlier this year, adding a vegan burger option at its global HQ in Chicago. The new McAloo Tikki -- which is already served in restaurants across India -- was introduced at the end of 2018. Outside of the U.S., McDonald\u2019s offers vegan-friendly veggie wraps and Happy Meals in the UK, and vegetable nuggets in Norway. It also announced earlier this year that it's working on a new meat-free option for Australian customers. In McDonald's Germany and Israel, customers can get the Big Vegan. The McDonald\u2019s burger every conscious consumer wants on the fast-food menu is the McVegan. Currently only available in Sweden and Finland, the McVegan consists of a soy patty, flavored with mushroom powder, onions, and peppers. Forbes recently reported that more than 160,000 people have now signed a petition asking the fast food chain to bring the McVegan to its American restaurants.
