This is NOT a regular mountain dew flavor. I'm not sure why they're trying to pass it off as such. It tastes like some sort of diet pop. The "regular" pepsi is the same way. I'm not sure why they have to ruin all soda stream items with artificial sweetener but I probably won't be buying any more of these.
This is not regular mtn dew. Tastes okay, but it is misrepresented. Its sugar free, and is sweetened with sucralose which has a horrible bitter aftertaste. Relabel it as mtn dew zero or diet. If you like diet mtn dew, its probably great.
I really enjoy the branded flavors: Pepsi, Mountain Dew, and Starry. They taste very good with half the sugar as regular soda. Much better tasting than diet or zero calorie soda. I wish they would come out with more branded flavors.
If I'd known there was acesulfame in the mix, I would never have purchased it. The mix tastes like a diet drink, and is frankly ruined (for me) by the inclusion of chemicals that alter the flavor. Great idea, not well executed.
