But beta-glucans aren’t the problem with rye — it has less than barley. It’s the arabinoxylans that make it gummy and viscous.
but arabinoxylans are essentially a non-degradable fiber so there no rest that's going to significantly modify that
I think they're pretty much impervious to everything except exogenous enzymes (and I'm not sure those are available in food grade.) I BIAB too, and don't really mind slow draining. The syrupiness is pretty much only a problem with the current beer -- I've made roggenbier with >50% rye and a normal gravity, and been happy with the results.I make a Kentucky Common with corn grits and rye malt. Even with BIAB I have slow draining. I was thinking of using the rye in the cereal mash instead of pilsner malt,so the rye would be boiled along with the corn.
Is this a good idea ? Will this break down the arabino's ?
