Subject: More on rice hulls
OK, I have to admit it: I use rice hulls every time I brew and I have no
idea why. Can someone please explain? Is it mechanical (good filter
material)? Chemical? Should I them at the bottom of my mash/lauter
tun, or mix it throughout the mash? Once upon a time after a stuck
mash, someone recommended them to me, and I haven't had a stuck mash
since. Generally, I prefer science to superstition, so, what gives with
rice hulls?
My suspicion: My stuck mash was during one of my two wheat beers. I
also suspect that the hulls are supposed to migrate to the bottom when
you circulate the wort prior to sparging. Since I use my mash tun as my
lauter tun, should I always use rice hulls, or only with sticky
adjuncts? I've got a manifold with a bunch of hacksaw slits, if that
makes any difference.

Subject: Re: Perfect sterilization solution
Hi,
In response to the Perfect Sterilization Solution post, I think this
is total BS.
Here is a old (and very bad) joke a chemistry professor told me in college
Two chemistry majors walk into a bar. The bartender says to the first,
"What can I get for you?"
"H2O."
"And you," asks the bartender?
"I'll have an H20, too."
The second guy died.
For those who are not chemistry majors, the second guy ordered H2O2,
commonly known as hydrogen peroxide which is a very common
disinfectant. There is alot of BS floating around about hydrogen
peroxide claiming that it can cure cancer, AIDS, and just about
everything else. There have been deaths associated with people trying
to use it in this manner. The FDA has issued a report on it in 1989.
This company is simply just another peddler of misinformation.
Hydrogen peroxide is toxic at any concentration and is lethal in large
doses.

Subject: RE: taking into account the rice hulls?
Since I use a cooler as a mash tun, what I do is this.
I always pre-heat my cooler with hot water while I am prepping everything
else to avoid heat loss by adding strike water to a cold container. You can
toss the rice hulls in at this point. When you drain the pre-heat water,
you have pre-soaked hulls that wont affect your strike volume.

Subject: Ethanol-y taste and cidery flavors
Greg asks what I mean by "ethanol-y":
>OK, I'll bite. What's an ethanol-y taste? What real
>beer doesn't taste of ethanol?
I guess I mean a "hot" or "unmellowed" alcohol taste
and smell that I notice in young beer(especially young
high gravity beer). To me it is even more apparent in
young cider. I also find that (as with that tripel)
it ages out--though obviously with enough sugar it
wouldn't (pure ethanol, for instance).
I think probably this taste is related to the "cidery
flavors and sugar" thing. Maybe when there's not
enough malt flavor to back up the alcohol you taste
mostly alcohol and it's a lot like cider. This was
posed in some post by de Piro, and I tend to buy it,
instead of various theories involving "invertase
flavor" or increased appleish esters. Maybe I'll do a
blind tasting of beers with various amounts of vodka
or water added and report the results.
If someone really wanted to know if ethanol is the
sole cause of cidery flavor they could add some of
corn sugar to half a batch of wort, ferment both
halves, and then add the right amount of Everclear to
the other half batch, then compare them. Anyone ever
done that?
I have no understanding of how or why such a flavor
would mellow but it happened with our tripel and has
been reported in the archives. If anyone can explain
why, I'd be interested to hear.
Matt
