I think Squirt has wood rosin in it too. So I just looked up the ingredients, and it appears that the formula has changed.

But if you scroll down, to Slice and Tropicana products, you can see it is in those now instead!

It is still in Squirt:

So what is "wood rosin" ?

So I wonder why Pepsi took it out of Mountain Dew recently?
I bet there is a reason.

I really like the Diet version of Lipton Green tea. I have one a day. Sometimes I have a Diet Vernor's But not every day either.

I tend to let the bubbles work off since carbonation is hard on me now that I am older. Vernors was a local product when I was growing up. It is an acquired taste still today.

It seems the wood rosin is in fruit type drinks that are not "clear" but opaque. Why it is not listed on Mountain Dew anymore is a mystery to me.
