In the interest of science, I'm trying to gather some info on the use of various protease enzymes to clarify beer. Has anyone used a serine protease like papain conjugates or Amino-Quik? Or a proline endoprotease like Clarity-Ferm?
I've been reading through old threads and other websites and have found very little information where homebrewers have actually used any of the above and given relevant results.
Qualitatively, I'd like to know:
-Did you add to the mash, or pitch with yeast?
-Was the body or head retention negatively impacted?
-Did you notice any negative effects on the fermentation (i.e, longer lag phase than usual or higher finishing gravity than expected?)
-Was the finished beer's clarity satisfactory?
I'm probably going to perform a controlled experiment comparing the efficacy and drawbacks of non-malt proteases in the foreseeable future, but before I go and blow my ramen noodle funds for the next two months, I'd like to get some opinions first.
