It tastes the same, smells the same... I dont see any changes.
Edit
One thing that I find different after I spent more time with it.
First the smell is a bit less sweet. I can smell the sweetness when I smell "butter" and I do not smell as much sweetness with Golden Butter. (My previous gallon of "Butter" is a lot older than this gallon and could be why...)
The taste is still spot on, and It works just as well in the receipe that I have been using "Butter" in.
The original 'butter' flavor is discontinued which is a shame. I am not sure I can sub golden butter in for my flavors that call for butter... Is sweet butter discontinued as well?
Sweet butter was the original and has been discontinued and replaced with golden butter, which to me is the same.
So why did they discontinue "butter"... Lame.
So no one is going to ask? Fine... You ordered a gallon of it without knowing beforehand what it was? Or you called before found out and the double label was just a coincidence?
