I bought this vanilla thinking it was grain free (meaning gluten & corn free). From what I can tell, it is NOT corn free, only gluten free. That is why I cannot give it the full 5 stars. It is a very nice vanilla if you do not have dietary restrictions.
I have a corn intolerance and have problems with vanilla extracts in general. I emailed the company and they replied that their alcohol is made from sugar cane. I tried the product and I had no reaction - yippee! Additionally, this product has a really rich vanilla flavor. I loved the flavor it gave to my buttercream frosting. Highly recommend it.
