This stuff is awful. I'm not saying it doesn't taste like Mt. Dew Zero, I'm just saying it was terrible. I'd never had MD Zero before, but I used to like Mt. Dew as a kid. Obviously not liking it as an adult.
My husband and son drink this every day. It tastes just like the store bought soda. We buy flavor syrups like raspberry, peach and strawberry to enhance the sodastream experience.
I really like the Zero Sugar Mountain Dew made with my Soda Stream. Historically Mtn Dew has been on the flatter side when purchased in bottles or cans so being able to make it myself I can fix that by adding more fizz. So now I get the same delicious taste but fizzier! This will be a regular buy for me.
