Judges DON'T see the name of the beer?!! Well, I guess that explains why my
"50 point Porter", "World's Best Wit", "First Place Pale Ale" and "BOS
Barleywine" haven't been doing as well in competitions as I had expected
them to. Sigh, I guess I'll have to resort to old-fashioned methods for
winning comps. Like buying a $3000 brew system, and sticking with liquid
yeasts. ;-)

Subject: Las Vegas Water; S.Cal HB Shops
Andy asks about suggestions for his Las Vegas brewing water for mashing.
Here is his water report data:
Temp hardness 131 ppm
sodium 84 ppm
chloride 71.5 ppm
sulfate 224 ppm
calcium 74 ppm
magnesium 28.6 ppm
pH 7.9
Total dissalved solids 614 ppm
total hardness 302 ppm
But what is missing is the other half of the equation - the alkalinity
or bicarbonate concentration. Without the alkalinity, there is not
enough data to determine how the water will behave in the mash, and it
is nearly impossible to calculate what salt additions to make to
replicate another city's water. Of course, there is a caveat here: the
pH is 7.9, so you can attempt an ionic balance to estimate what the
bicarbonate concentration is, and you would probably be in the
ballpark. Probably easier to take another look at the report or call
the city public works department to find out.
Be that as it may, if Andy likes to brew British ales, I would say he's
there. There is no need to remove the temporary hardness, you can use
that mineral content to your advantage. The sulfate concentration is
good too.

Subject: Water
The following water analysis
Temp hardness 131 ppm
sodium 84 ppm
chloride 71.5 ppm
sulfate 224 ppm
calcium 74 ppm
magnesium 28.6 ppm
pH 7.9
Total dissalved solids 614 ppm
total hardness 302 ppm
doesn't tell us the most important brewing parameter which is the
alkalinity but we can guess that it is about 268 from the other
numbers. This would give a residual alkalinity of almost 200 which is
the real problem with this water even for British beers (to which you
are pretty much limited by the large sulfate content). Decarbonation by
boiling should work and yes, you need to decant the water off the
precipitate or in particular make sure the precipitate doesn't get into
the mash tun, at least, as letting it in would be like adding chalk to
your mash and totally defeat the decarbonation. Of lesser importance is
that over time carbon dioxide from the atmosphere will dissolve in the
water and cause some (but not all) of the precipitated chalk to go back
into solution. It is not necessary to decant immediately. The
redissolution takes some time.
Adding phosphoric acid probably isn't the greatest idea as you can
overshoot easily as you note (so be sure to use a pH meter and stop
adding when the water reaches a pH around 7) and it will also strip out
most of the calcium some of which you want to keep in there. You are so
heavy in sulfate and chloride that you don't want to add either
additional gypsum or calcium chloride. (Note that the boiling above
will leave plenty of calcium and magnesium). Other mineral acids
(hydrochloric or sulfuric) would probably be better bets but these
will, obviously, increase sulfate or chloride depending on which you
choose. If acid addition is to be considered perhaps lactic would be a
good choice but it will flavor the beer. IMO the best source of acid is
dark grains.
Obviously dilution with an equal volume of RO water cuts all the
numbers in half but it still leaves 100 ppm as CaCO3 residual
alkalinity which is still a bit high. 3 parts RO water to 1 part tap
water gets the RA down around 50 which is easier to deal with, still
leaves plenty of calcium and gets the sulfate and chloride down to the
point where you could supplement the calcium with gypsum or calcium
chloride without getting too much of either of those anions.
Using all RO and building up the mineral profile is clearly the best
option in terms of the control and flexibility it lends. Dilution with
RO water is probably the simplest.

Subject: Upgrading All-Grain System
Fellow Homebrewers,
I'm sitting over here in the desert wishing I was homebrewing. I've decided
it's time to upgrade my 5 gallon labor intensive system when I return home
this spring.
I can't imagine brewing 10 gallons at a time. I just can't drink that much
beer. I've been checking out brew kettles at SABCO, Northern Brewer, and
More Beer. Presently, I boil in a 7.5 gallon SS bargain brand kettle
without a valve which means using an immersion chiller and a sanitized Pyrex
measuring cup and funnel to transfer to the carboy...time consuming and
labor intensive.
It's time for a kettle with a valve, a hop back, and a counterflow chiller.
Tell me about ball valves and quick disconnects. I've seen mention of 3/8
inch or 1/2 inch ball valves with a barbed outlet. I've seen a choice
between brass or plastic disconnects. I don't have a brew sculpture or
designated brew bench...I assemble and disassemble between brews.
Should I go with barbed outlets and use silicone hose between the kettle,
hop back, and chiller, or should I use quick disconnects?
Do I have to use a pump with hop backs?
Are there any particular kettle, hop back, chiller combinations that work
well together?

Subject: Re: Water analysis suggestions to improve mash
Dear Friends,
In #4412 Andy in Las Vegas asks about treating his water of a given
analysis and lists a few options for dealing with it. Andy, I always use
your Option One (starting with RO water and adding salts to match
the desired target) anymore, I just find it far simpler and faster to
treat the "blank slate" of RO water to get what I'm after. I have the 5-
gal water-cooler plastic bottles and our grocery has the RO machine
right there next to the frozen aisle, so it's very convenient and it's
worth the extra four bucks for the convenience IMO.

Subject: Re: Water
Great response, and thanks for the insite. I will likely start using more RO
water than the 50-50 I did last time. Also, where I labled "temporary
hardness" should have said alkalinity (it IS labled as alkalynity in my most
recent water analysis but I thought the terms were interchangeable) So at
least the water isn't as bad as it could be.
Perhaps I will just start using all RO water and building it up from there.
Anyone know what is the going rate for an adequate RO system?
Thanks for the response.

Andy,
I think you're in great shape with the above water analysis. My water has
146 ppm bicarb with a pH of 9.2. As long as I make sure my calcium is at
least 75-100 ppm, I haven't had any trouble with my mash getting to the
desirable pH of 5.2-5.5.
If your mash pH doesn't come down to the desired range, then I would
recommend adding acid to get original water to a neutral pH (6.8), and then
mash. Also, I would recommend adding acid to your sparge water to get it
below pH of 6. I take my sparge water to pH of 5.8.
I'm not sure, but the sulfate level may make it difficult to brew a soft,
malty beer. You may want to experiment by diluting your water with RO
water.
If you're brewing malty beers, you may want to add 1 teaspoon of CaCl. By
my calculations, this would add 43 ppm Ca and 89 ppm Cl. If you're brewing
hoppy beers, you may want to add 1/2 - 1 teaspoon of gypsum. 1 t would add
approx. 50 ppm Ca and 107 ppm SO4. Keep in mind brewing books say a Sulfate
level greater than 450-500 ppm can give excess bitterness.

For those with a handy streak who aren't afraid of a soldering iron I
have found this link invaluable.

I have used the information from this web page to build my own
thermometer several temperature controllers for a refrigerator and a
chest freezer and also incorporated it in the temperature controller of
my RIM system. Most of the parts can be obtained from Radio Shack and
for folks like me who like building the equipment as much as brewing the
beer this is a great way to go.

Subject: Loathing the water in Las Vegas
Andy asks for options for brewing water adjustments for the water in Las
Vegas. Andy is almost correct in stating that "Other than the temp
hardness, it doesn't look that bad". The other thing that concerns me is
the high magnesium and sodium content.
Andy says he considered several options for water adjustment, but I have to
recommend that dilution with RO water is probably the way to go for most
brewing styles. The existing water does look OK for use as a "Burtonized"
water.
Andy considers using all RO water and adding minerals as needed. This is
always an option, but not necessary in all cases. The 50/50 dilution is a
pretty good suggestion for many brewing styles. The other suggestions that
Andy proposes, boiling with decanting and acid addition, are possibilities
for addressing the alkalinity problem. But, they don't address the other
mineral excesses.
The existing water has a slightly high residual alkalinity (RA) of 61. That
makes it a little unsuited for pale beers. An acid addition takes care of
that. My calculations show that it will take 2.5 tsp of 30% phosphoric to
bring 5 gal of sparge water to pH 5.3. It only takes 0.17 tsp of that acid
to neutralize the alkalinity in about 2.5 gal of mash water. One of those
graduated medicine droppers is just the ticket for gauging acid additions.
Diluting the existing water with 50% RO water does a world of good for this
water. The diluted water has ion concentrations of: Ca = 37ppm, Mg = 14ppm,
Na = 42ppm, Sulfate = 112ppm, Cl = 36ppm, and Bicarb = 79ppm. The RA drops
to about 30. It will only take 1.25 tsp of the phosphoric to treat the 5
gal of sparge water to pH 5.3. A miniscule .06 tsp of the acid will
neutralize 2.5 gal of mash water. With the low RA, I wouldn't bother with
any mash water pH adjustments. The mash should take care of itself.
I've only been to Las Vegas a few times. I'm surprised that I didn't notice
the minerally nature of the water there. I guess I was drinking other stuff
there ;-) Its my understanding that most of the city's water comes from the
Colorado River. I would have expected a lower degree of mineralization for
a surface water source, but I guess its a long river! I hope to be back in
Las Vegas this summer for some Beer and Loathing. I'll be sure to taste the
water then.

You'll find a directory of homebrew shops at the Brew Your Own website
(www.byo.com). The home page has a homebrew supply directory link for the
whole country. I've found it is up to date for the LA area. You're in

are now available for you to bid upon on ebay. They make a great Christmas
gift for yourself or your brewing friends, and I can personally attest that
they look GREAT on any bookshelf! Each set contains:
The Complete Practical Brewer, 1852, by M.L. Byrn
The Complete Practical Distiller, 1875, by M.L. Byrn
The Town and Country Brewery Book, circa 1830, by W. Brande
The auction on these fine publications commences at 12:00am, Tuesday,
12/02/2003 and will run for a week, this to allow those who can only read at
work a fair chance!. The following URLs will take you to their listings once
the auction has commenced.
