I struggle between giving this 3 or 4, even 5 stars - because I am just thankful for the substitute, as I have a condition that I need low acid coffee for. However, I DO have to admit, it tastes like burnt coffee (as someone else put it) and it is no Peets or Starbucks. The taste, and the flavor it leaves in your mouth after you are done, is something I don't think I will ever get used to.  Update: I had my father in law up. Would like to say that if you are one, like he is, that puts mounds of creamer and sugar in your coffee...apparently you will not notice a difference in taste from this brand to another. Hope that helps!
Wonderful substitute...

We have been living gluten-free for 5 years now, and this mix is the best I have found!  It makes great waffles.
Amazing!

I really wanted these to taste good, but there is something in there that is very bitter. I had to add too much sugar to make them even slightly palatable. No one would eat them. They LOOKED delicious after baking and they're healthy, but that's only if you manage to choke one down. I have tried their gingerbread, corn muffin mix, and jalapeno cornbread mix and those are all great.

Oh so bitter tasting......
