I tried Shakparo when it appeared at my local liquor store and had an adverse reaction twice. I consider myself to be highly sensitive celiac positive. I emailed the brewery to inquire weather or not they brew their gluten free beers on the same equipment as their regular beers. the following is their response:
"Yes it is, all of our products are made in the same brew kettle. After each use they are sterilized."
Buyer beware! While all the ingredients are gluten free (not gluten removed) I have found this beer to cause severe reactions.
