Subject: Acidifying sparge water
This usually isn't necessary as the pH during the sparge isn't critical
as long as it stays below 6 or so to reduce the amount of husk tanins
brought over. If the source water is at high pH and alkaline then you
may find you reach pH 6 before all the sugar is extracted and this is
the case in which you may want to add some acid. If the pH of your
runoff is 6 or less when the runoff has reached 3 P then you should be
OK without treatment of the sparge water. At 3 P each gallon of runoff
you leave behind contains about 120 grams (approximately 4 litres x
approximataely 1 kg/liter x .03) of extract (about 4 Oz or 1 Oz per
quart) so it's not generally worth pushing it and risking tanin
extraction or taking the trouble to adjust the sparge water and winding
up with acid anions in the brew.
If the water is very alkaline (you are hitting pH 6 when the extract is
5 P or higher) then you may wish to decarbonate it somewhat. Sparge
water has to be heated to 170F or so anyway and you might just want to
take it up to boiling to let it drop carbonate (it turns murky). The
amount of carbonate it drops can be increased by adding a calcium salt
such as the chloride or sulfate but this increases the amount of those
anions going into the kettle. Also adding a wee bit of calcium carbonate
insures nucleation sites for the CaCO3 that is to precipitate. A larger
problem with this suggestion is that it takes time for the calcium
carbonate to settle. If you are treating the mash water in this way (or
some other way as with, for example, lime) increase the volume treated
to include the sparge water.
If you are determined to use acid then the advice already given is
valid. The amount of acid required, in milliequivalents per liter, is
approximately the alkalinity of the water in the same units i.e. if the
alkalinity of the water is 200 ppm as CaCO3 then approximately 200/50 =
4 mEq/L acid will be required. This approximation holds as long as the
starting pH of the water is 8.3 or less. Most potable sources qualify.
The approximation is pretty fair as long as the pH change is a couple of
points i.e 8.3 to 6 or 7 to 5. The amount required can be more precisely
caculated using the steps set out at
http://www.wetnewf.org/Brewing_articles/Water_acidification.html but a
pH meter or test strips should be your guide as there are lots of ways
to have the calculated acid amount get you to a pH other than the one
you wanted. So what pH do you want? In a worst case we might suppose
the source water was at pH 8.3 (near the limit allowed for municipal
water in the US). If the pH is reduced to 6 almost 70% of the alkalinity
will have been neutralized so 6 seems like a reasonable target.
Let me comment briefly on Ron's unfortunate experiences with pH meters.
I certainly have had similar experiences in the past but technology has
advanced. I am now almost to the 3 year point (to be reached in May) on
a relatively simple gel filled electrode. This is a record for me and
I'm somewhat in disbelief but this electrode, while its response is
slower than it was in the past, still has 97-98% of the Nernst slope and
an offset which hasn't shifted more than a couple of mV from what it was
when new. I have never even used enzyme cleaner on it. I do put it into
wort but not hot wort and I think that must have a lot to do with it.
Apparently the stresses of going from hot to cold are most effective at
reducing electrode life. Now this is not a $78 item I bought at a
homebrew shop but it isn't a $300 double junction refillable electrode
either.

Subject: Boston Homebrew Competition
It is with great pleasure that The Boston Wort Processors present the
13th Annual Boston Homebrew Competition, sponsored by the Allagash
Brewing Company, on Saturday, March 1st. This year's competition
follows in the fine tradition of brewing and judging that has been
proven at our previous competitions. This competition attracts
entries from many of the best brewers not only in New England but
across the country and is judged by many of the founding members of
the Beer Judge Certification Program. We look forward to your
participation this year.
This is a BJCP Registered/Sanctioned event and we will be judging all
28 BJCP 2004 Styles for this competition. Also, as has been the case
since its founding, this year's contest again will be part of the New
England Homebrewer of the Year series and as in past years, will serve
as the Northeast Region Qualifying Event for the Masters Championship
of Amateur Brewing (MCAB).
For information about the competition, to register enteries, or to
signup to judge or steward, please see http://bhc.wort.org.

Bah, I consider the expense an investment in my sanity. Washing, sanitizing,
filling and capping bottles, thousands and thousands of times in your
brewing life... How do you put a price tag on avoiding that? A keg fridge is
worth it at twice that price.
Having said that, I refuse to spend $100 on a fancy drip tray. I consider
this a completely needless expense for a piece of gear that just isn't
required. A cheap plastic tray on the floor under the taps does the same
thing.

Subject: sugar
I've enjoyed Lagunitas' "Brown Shugga" quite a bit, and am considering
trying something similar at home. Not surprisingly, this beer
contains a significant amount of brown sugar, by some accounts 200lbs
per batch. I'm not sure what that comes out to in lb/gallon, but my
question to HBDers is this: If you've used brown sugar, table sugar,
molasses, belgian candi sugar, or other forms of sucrose, how much
have you added? What are the limits past which flavor is negatively
affected?
I've read that back in the "olden days" of home brewing, many recipes
were 50% table sugar or more, and generally had a negative,
sherry-like flavor. In my opinion, the commercial ale in question has
a surprisingly light body and warm alcohol notes that nicely
complement the flavor of the beer. That, and, at 9.9%, it'll knock ya
back in yer chair....
Thoughts?

It is possible to get the Chimay yeast right from a bottle of Chimay. A
while back I collected about 1/4 ounce of stirred beer from a bottle of
Chimay. I think it was the red label, but any should work. In the past the
corks were dated, but that seems to be gone now. If you can get a fresh
shipment, try it in a stir plate. It took about 4 days to show any
activity. Start with a small starter, an ounce or so, then build it up a
couple times.
The findshed beer tasted like Chimay!
