Subject: Re: Braggots
Given the low to none usage of hops in a
Strong Scotch Ale and the current price
of hops, a Wee Heavy Braggot seems like
a good idea. Dave's point on the
caramelization is well taken and that
may take a very long boil with or
without hops.
If I do use hops with a 10 gallon batch
and boil for 90 minutes or more, would
an ounce of Fuggles be too much or too
little?

Subject: Accepting Entries for the 15th Annual BUZZ Off in West Chester, PA
On Saturday, June 7th, Brewers Unlimited Zany Zymurgists (BUZZ) is holding
the 2008 BUZZ Off home brew competition at Iron Hill Brewery & Restaurant in
West Chester, PA. The BUZZ Off is one of the top Philadelphia area homebrew
competitions featuring some of the best beers, meads and ciders from around
the country. In addition we are proud to announce that a portion of our
proceeds will be donated to Philabundance (http://www.philabundance.org/), a
local organization committed to hunger relief in the Delaware Valley.
For another year we are a qualifying event for the prestigious Masters
Championship of Amateur Brewing (MCAB). We are now accepting entries from
May 12th through May 24th (23rd for mail in). For complete details and
entry forms, please see our website, http://hbd.org/buzz.
Thank you for your support!

Subject: Solarflo Jet Burner Sources
Does anyone know of a source for the full line of Solarflo jet burners?
http://www.solarflo.com/impinged.htm
They won't talk to me, only manufacturers, and I can't find anyone who
carries their full product line or can give me any solid information.
If anyone knows of a supplier that can get me their full impinged and
slotted jets catalog, as well as any engineering documentation I'd be
forever in your debt. I know they have some documentation not posted on
their web site because I found some here:
http://www.teecoproducts.com/catalog/I5.htm#1
They won't talk to me either, but I'm pretty sure that this page came
directly from Solarflo because all their other descriptions did.
I also need a place that will actually sell it to me.
What I'm looking for and what I want to know is whether the Solarflow
slotted jets have a higher turn-down ratio than their impinged jets. I
need a high quality, energy efficient burner to use under my 55-gal
boiling kettle whose firing rate is capable of being modulated with a
butterfly valve. I've used Chinese-made "wok burners" (impinged jet) in
the past, but like most things from China, they're not very well made
(shoddy tolerances). All the outdoor burners I've seen are horribly
inefficient, and given that I'm going to be doing 175-L boils I'm
really going to want the efficiency, given the cost of fuel.
I'm estimating that I'm going to need ~28,000-Btu to bring 175-L from
65*C to ~99*C and ~32,000-Btu to boil 175-L for 1-hour with an
evaporation rate of 7.5%/hr. Those calculations do NOT take into
account the efficiency of the burner, just the number of Btu's that
need to actually get into the kettle. Figuring that the burner should
be ~70% efficient, that makes ~36,000-Btu input to bring the wort up to
boil and ~42,000-Btu/hr input to boil at a 7.5% evaporation rate. So, I
figure a 50,000-Btu/hr burner should do the trick, and, by having the
ability to modulate the firing rate I'll be able to reduce the risk of
the inevitable boil-over at the start of boil by throttling back the
full-fire rate back to a safe level.
If anyone has any good alternatives to the types of burners I'm
contemplating, I'm all ears. I also realize that any burner I get is
not going to be cheap...
[Note: this burner is going to be used indoors, housed in a combustion
chamber beneath the kettle with outside air piped in from below to
provide ALL primary and secondary combustion air...and yes, there is
going to be a properly sized flue attached to exhaust all combustion
gas. There will also be a CO/combustable gas alarm in the room as well.
I'm very aware of the dangers here, but it's just a scaled down version
of any gas-fired professional kettle...]
On a brighter note, Grainger sells a really nifty 1/2-in. NPT butterfly
valve for $10...the downside is that it's only rated for 120*F for
water service. I'm going to use it to modulate the gas going into the
burner...you can look at it here (it also comes in 1/4, 3/8, 3/4-in):
