---------------------------------------------------------------------- Date: Mon, 23 May 2005 00:01:22 -0400 From: Scott McAfee <scmcafee at cox.net> 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. -Scott Return to table of contents

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. link to FDA http://www.fda.gov/bbs/topics/NEWS/NEW00122.html Link to quackwatch http://www.quackwatch.org/11Ind/shortt.html Here is a page of water related pseudo science.

Date: Mon, 23 May 2005 09:35:00 -0700 From: "Richard S Sloan" <richard.s.sloan at us.hsbc.com> 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.

Date: Mon, 23 May 2005 09:52:04 -0700 (PDT) From: Matt <baumssl27 at yahoo.com> 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 Return to table of contents
