What about mashing it out? Such as performing the same method as you wood (pun intended) with extracting the fermentables from the grains, and making sure you do not go over the 170 degree mark so you do not extract the tannins. From my understanding, I believe you would extract tannins from the grains if you go over that temp right?
Just a thought, and thanks
