---------------------------------------------------------------------- Date: Tue, 22 Jan 2008 00:15:13 -0600 From: "Brian Lundeen" <blundeen at mts.net> Subject: Hot water heater elements One of the great things about the HBD is that it seems to attract a lot of expertise in areas other than pure brewing knowledge. I am hopeful that somewhere out there is a person with a deep knowledge of the world of hot water heater elements. My electric kettle (built in Saskatoon Canada by someone who at last contact seemed to want to distance himself from ever having sold these commercially for fear of lawsuits)is fitted with a couple of 3000W low watt density elements which appear to be Giant 10G30 80 units, at least that is what is on the back cover plate. After my latest brew session, I seem to have scrubbed my way from a nice shiny copper surface to a dull silver one. In other words, my latest cleaning with a hot PBW solution and a soft scrubbie has taken away much of the copper sheathing and mostly exposed the metal underneath. I had no idea my cleaning regimen would do this to copper, but what's done is done, and I am now left with a dull silvery element of unknown makeup. Can anyone tell me what this is, and whether it is safe to continue using for boiling my wort? Thanks Brian, in Winterpeg Return to table of contents

Date: Tue, 22 Jan 2008 08:47:31 -0600 From: "Joe Walts" <jwalts at gmail.com> Subject: Re: Incredible head foam stability I doubt that the atmospheric change has much to do with the beer's foam. Most cabins are pressurized to the equivalent of 8000 ft altitude, or 10.91 psia (compared with 14.696 at sea-level). The respective partial pressures of carbon dioxide at sea-level and 8,000 ft, which determine CO2 escape rates, are 0.56 and 0.42 psia. The difference should be pretty negligible compared with the ~26 psia (~11 psig) of CO2 in a cold Bud. If anything, the foam would dissipate slightly faster at cabin pressure because of the increased pressure gradient between the beer and the air. It's the opposite of nitrogenating a draft beer. The American Society of Brewing Chemists' journals are stuffed with research on foam stability, which never fails to glaze my eyes. I'm pretty sure the big guys use synthetic chemicals, which doesn't do much to stop the widespread practice of pouring their beers with as little head as possible.

Las Vegas Winterfest 2008 is just weeks away, on 9 February 2008. We're looking to grow the competition back to what it used to be, and we need your entries! Two bottles and $7.00 is all it takes to get your beer, mead, or cider in. Shipped entries are accepted 21 January to 1 February...in other words, Right Now. :-) If you're coming from out of town to judge or steward, you can save a few bucks and bring your entries with you. This year's competition will be held at the Freakin' Frog, on Maryland Parkway across from UNLV. We'll need all of the judges and stewards we can muster; if you're interested, send me some mail. It's not too late! For more detailed info, see our competition webpage: http://www.nevadabrew.com/twiki/bin/view/Competitions/Winterfest08Announce If you're not familiar with Las Vegas or don't know where to find the Freakin' Frog, look no further than this link (split across two lines because HBD barfs on long lines): http://maps.google.com/maps?f=q&hl=en&q=4700+Maryland+Pkwy,+Las+Vegas,+NV&i e=UTF8&om=1&z=15&ll=36.104873,-115.137234&spn=0.023647,0.053301&iwloc=addr Thanks, and good luck to all entrants! I'd especially like to thank in advance the judges and stewards, as without them, homebrew contests just don't work. :-) Scott Alfter scott at beerandloafing.org Return to table of contents
Date: Tue, 22 Jan 2008 20:57:32 -0000 From: "Antony Hayes" <anthayes at btinternet.com> Subject: Long range planning: Great British Beer Festival The Great British Beer Festival runs from 5th to 9th August 2008 (http://www.camra.org.uk/page.aspx?o=195496). This is a great beer festival, and well worth the short trip over the Atlantic. The London Amateur Brewers meet on 4th August, and any homebrewers over for the festival are welcome to attend. Please let me know if you are keen. Cheers Ant Hayes Hildenborough, Kent Return to table of contents
