More to come on that soon Ethan! Fruit is a great adjunct as well, not as much for body though, but one of my personal favorites to utilize, especially in big beers.
I have a gluten Intolerance- and have consistently used clarity ferm- specifically because I like to use liquid yeast- which has a tendency to have a gluten content as well. I've heard of people not using clarity ferm with Spelt and not having problems... but I don't personally take the risk...
