Mountain Dew Throwback is by far the best tasting Mountain Dew yet. It's got the taste of Dew but they use real sugar instead of syrup so you don't get that gross tasting syrupy after-taste.
I'm not surprised White-Out won considering it had the smoothest taste to it but then again the color is hideous.
I personally thought Typhoon was the best, it was sweet and fruit punchy but had like a kick of pineapple to it that made it delicious. If they had used real sugar instead of syrup and made it a little less sweet it would have been amazing.
On a side not Code Red is awesome but too sweet for an all the time drink. And Baja Blast is good but it'll never leave Taco Bell, not sure if thats a bad thing though.
