Yes, friends, TWO (count them, two) web sites on some odd side soda in the Coca-Cola universe. One of them a (mostly) dead brand, the other a brand about to be released nationally.
I remember Surge. I actually liked it when it came out; as it was a less sweet version of Mountain Dew. Not only that, but the taste was a bit stronger. In fact, it has a slight peppery taste that popped up towards the back of the tongue. It wasn't bitter, but it definitely had a spicy taste to it.
In the end, I believe it was that spicy
Now we have Vault. It's Surge, but with a better coloring (yellowish instead of dayglo green) and without that peppery back-taste. I'm looking forward to it, as I still love the Surge Taste and Vault Has it.
BTW...Mountain Dew MDX sucks! It's "power pack" is definitely powerless. I've tried it, definitely did nothing to keep me from sleeping on my job.
