Good news, Millennials: Diet Coke is introducing four new flavors that are sure to tickle your taste buds. 
 
 At least that's what Coca-Cola (KO) is hoping. 
 
 Starting in two weeks, you can buy Diet Coke in Ginger Lime, Feisty Cherry, Zesty Blood Orange and Twisted Mango. 
 
 They will come in a skinnier silver can, reminiscent of Red Bull's. And the company may have had another drink in mind when it mixed up the flavors -- LaCroix seltzer, which has attracted exactly the audience Coke is after. 
 
 Coke wasn't shy about which customers it's targeting. 
 
 "Millennials are now thirstier than ever for adventures and new experiences, and we want to be right by their side," said Rafael Acevedo, the group director for Diet Coke in North America. "We're making the brand more relatable and more authentic." 
 
 Another Diet Coke executive said the company cast a "broad flavor net" after examining what Millennials are eating and drinking, and tested everything from spicy notes to exotic fruits.

 The company even released a video of Millennials trying the flavors. (Their most common reaction: "Whoa.") 
 
 Coca-Cola spent two years on the relaunch and says it asked more than 10,000 people for their thoughts. 
 
 The company is not changing the classic Diet Coke formula, which will still be available in the traditional, squatter 12-ounce cans. 
 
 Coke has been paying special attention to its low- and zero-calorie drinks. 
 
 Over the summer, the company replaced Coke Zero with a drink called Coca-Cola Zero Sugar. It paid off: Last quarter, the company reported earnings and sales that topped forecasts, thanks in part to growth from the new product. 
 
 But in general, consumer appetite for soda, both regular and diet, is shrinking. People are turning away from the artificial sweeteners used to flavor diet sodas -- including the new Diet Coke flavors. 
 
 In a note published on Tuesday, the research group Cowen reported that diet soda sales fell 2% in the last three months of 2017. In that period, Diet Coke sales fell by 4% and Diet Pepsi (PEP) by 8%.

 Other sodas have tried this strategy: Pepsi sought to appeal to younger drinkers last year with a disastrous ad featuring Kendall Jenner offering a soda to a police officer on a protest line. After a backlash, the company apologized and pulled the ad. 
 
 Companies like Coke might want to focus on sparkling water instead of new diet drinks. 
 
 Cowen noted that over that same period in 2017, National Beverage Corp., which makes LaCroix, reported that sales improved 43% in the sparkling and still flavored water category. 

 What Is It: Diet Coke’s new Twisted Mango, Ginger Lime, Feisty Cherry and Blood Orange flavors 
 
 Who Tried It: Mark Marino, PEOPLE contributing writer 
 
 Level of Difficulty: 2 (I know this should be a 1, but drinking four cans of soda can make one’s tummy bloated) 
 
 It’s been a rough week. The free soda machine at our office has been broken since Monday, so I’ve had to survive mostly on water. And for someone who lives on an all-carb diet (carbohydrates and carbonated beverages), that ain’t easy. So you can imagine why I almost did a backflip when a package arrived today containing all of Diet Coke’s new flavors: Feisty Cherry, Twisted Mango, Ginger Lime and Blood Orange. I was excited by the news that they were hitting the market this month, and I couldn’t wait to find out which flavors popped and which ones fizzled (get it?). 
 
 First up: Feisty Cherry. It tasted slightly syrupy and more cherry-y than Coke-y, which I kind of liked. I didn’t quite get what was feisty about it — although I suppose I’d be pretty feisty too if I was trapped inside a can all day. After a few more sips, I thought I detected a bit of a spicy sensation in the back of my throat. Was my Diet Coke getting feisty with me or was I imagining it? I’m still not sure. Either way, I would definitely drink this flavor again, despite its sassy attitude. 
 
 Next I tried Twisted Mango. The only twisted thing about this beverage is the person who came up with the concept. There are some things that just don’t mix well: mango and Diet Coke, oil and water, Peggy and the rest of the Real Housewives of Orange County… you get the idea. It has a nice scent, though, and if you place a few sticks in the opening of the can, I bet it would make a nifty room diffuser.

 I had high hopes for the Blood Orange flavor, since I fell in love with the fruit when I traveled to Ortigia, Sicily, a few years ago. When I took a sip, I hoped it would bring back memories of myself happily wandering through the town’s old, narrow streets, the locals placing curses upon me as I passed. Instead, I was getting the “Want a Fanta?” theme song by that legendary girl group the Fantanas. This tastes like Diet Coke mixed with regular orange soda. Or was that Anbesol? For some reason my tongue was feeling a bit numb. Either way, I think if you want orange in your soda, just buy orange soda.

 Last up: Ginger Lime. Maybe it was because the Feisty Cherry singed my throat and the Blood Orange killed my taste buds, but I could not detect any ginger whatsoever in this drink. It does have a pleasant lime flavor, though, which seems a bit more subtle than regular Diet Coke with Lime. I’d definitely drink this again — and I wouldn’t rule out using it to marinate chicken. 
 
 The Verdict: Uh… the cans are nice? Honestly, the Feisty Cherry and Ginger Lime flavors are pretty good, but the Twisted Mango and Blood Orange are disappointing. And all of the new flavors just seem completely unnecessary. If you’ve got a successful formula, don’t mess with it, because introducing something new can really throw things off. Have we learned nothing from RHOC‘s Peggy?
– It appears soda-makers are getting increasingly desperate to hook young people on their product. On Wednesday, Coca-Cola announced four new flavors of Diet Coke—Twisted Mango, Feisty Cherry, Ginger Lime, and Zesty Blood Orange—expressly targeting Millennials, CNN reports. "Millennials are now thirstier than ever for adventures and new experiences, and we want to be right by their side," one Diet Coke executive says, adding the new flavors are "more relatable" for young people. The new flavors will be packaged in skinny cans reminiscent of Red Bulls. Mark Marino, a contributing writer at People, tried all four flavors, which Coca-Cola says it spent two years working on and had over 10,000 people taste. While Marino's conclusions weren't entirely positive—"I wouldn’t rule out using it to marinate chicken" and "I bet it would make a nifty room diffuser," for example—he wouldn't rule out drinking two of them in the future. And, hey, even Millennials need a good room diffuser.
