5. Mountain Dew
We are half way through our list of most popular vending machine drinks, and at number 5 we have Mountain Dew. Mountain Dew seems to be extremely popular among customers who buy from vending machines. If you ask me, no drink should be the color of yellow highlighter ink, but that’s just my humble opinion. However, if you own a vending machine that dispenses soft drinks, then stocking up on Mountain Dew seems like a really good idea for a business. Mountain Dew has a CSD percentage of about 7% which is really impressive.
