Double Chocolate Nesquik

This product is a bit of a mystery. I don't know that it's necessarily "double" the chocolate of original Nesquik — the original Nesquik is already the best, most chocolatey mass-market brand of chocolate milk, and this just has a different kind of chocolate taste.

Nesquik Reduced Fat Chocolate Milk in a half gallon container

This replaced the Whole Milk version of Nesquik at every supermarket I've seen. This was an unfortunate decision by the good folks at Nestlé because it was quite a bit richer and better with whole milk than this watered-down version. But even in its new formulation, Nesquik is still probably the best mass-market chocolate milk.
