Subject: Re: Mashing on an Electric Coil Stove
In HBD1130 David Ferguson asks about mashing on an uncontrollable
stove:
I would suggest using decoction mashing when suitable for the beer
you're making. You'll only need the hottest and nothing settings.
An other method (which also buffers temperature drop) is
placing the mash-tun in a larger kettle with water.
(if you have a number of cheap enamel on
steel pots ranging from 5 to 40L(1.5-10Gal))

N2 coming out of solution from the blood, muscle and other fluids and body
tissues when a diver ascends too rapidly. This forms tiny bubbles that
cause neurological and physiological damage to the body.
Although diatomic nitrogen (N2) is a very stable element and is relatively
inert at low temperature and pressure, it is easily dissolved in fluids
such as blood, water or beer. I can't say if or why it causes a good head

Subject: Scotch Ale/Caramel Flavor
I tried to make a Scotch Ale six weeks ago or so, and I've just
opened the first couple of bottles. I used about 1/4 pound of
"Mexican" brown sugar in the five gallon batch. Mexican brown
sugar seems to be highly unrefined, and has an absolutely
delightful molasses taste to it.
Now that the yeast is firmly on the bottom of the bottles, I
can tell that there is very little molasses on the nose, and
just a faint aftertaste. Just for fun the other day, I went out
and bought some MacAndrews and McEwain's Scotch ale to compare.
Since I like the MacAndrews better, I'll talk about IT. The
first thing I noticed was a strong malt/caramel nose and
flavor. We're talking strength like drugstore candy. More
caramel than malt, I think. Tasty. My attempt doesn't come
close. MacAndrews has more hop bitterness than mine does, but
with all that caramel it probably needs it. The color, body,
gravity, head, and the rest are fine in the beer I made --
what's missing is the caramel flavor.
It was an all-grain recipe:
5# 2-row
4# Cara-Vienne
1# Cara-Munich
1/4# Mexican Brown Sugar
Wyeast 1098
7 HBU Kent Goldings bitter
Mashed at 155 F to get unfermentables up
The question I have is "How do I get the stronger caramel
flavor?" The only thing I can think of to try is to get a few
quarts of the strong first runnings from the lauter tun, and
boil the h*ll out of it while sparging the rest to caramelize
the sugars. Or maybe melt the brown sugar in a saucepan, and
caramelize it before adding it to the boil pot. Or maybe buy
some Brach's (tm)
caramel cubes and dissolve `em in the wort instead of the brown
sugar?
Got any ideas for me??

Subject: Humor
It appears that Ulick Stafford (ulick@bernini.helios.nd.edu) took my recent
attempt at humor over his "cake beer" as a personal insult and put down.
I meant nothing of the kind and apologized privately but thought it would be
useful to mention it publicly in case anyone else thought likewise.
When someone says he put cakes in his beer, it is more than I can resist. He
was obviously referring to cakes of baker's yeast. Just for the record, I
used dry yeast in my experiment and make no claims about any other type.
Also, for the record I refuse to use :) and accept the consequences.

Subject: Single Malt Scoth Whiskey
Re: Bottling.
Single Malt Scotch Whiskey refers to the Whiskey coming from a
single barrel. A whiskey like Chivas Regal is a blended
whiskey. In a blended whiskey the intent is to produce a
product with identical taste from year to year. With a Single
Malt whiskey each barrel will have differnt taste, however subtle
that provides a tasting adventure to the drinker.
If what you have is indeed barrels of single malt whiskey . I would
bottle the contents of each barrel separately and label accordingly
and enjoy the nectar of the heather.
Regarding bottling and flame point, If flamibility is an issue do it
in a well ventilated place like outside. Reusing glass liquor bottles
with screw caps should be acceptable or wine bottles with corks. The
liquor bottle and screw cap seems more practical with regards to re capping.
On principle I would not use plastic liquor bottles.

I have not tried a vent pipe, but I would guess that due to grain compaction
you will get a very large flow through the vent pipe and this would make for
alot of HSA and poor heat transfer in the heater due to all the foam. ie I
don't like it. Still an anti-RIMS zealot!
There are still alot of micros using dry yeast. The dry yeast used to come
from Siebels and was of a pretty high quality. I understand from Micah that
they are now being sold by Crosby and Baker (I think). He is planning on
using them at Murphy's Creek. The use of dry yeast in brewing at micros,
when you pitch a brick of yeast in a batch provides a large population of
good guys to bad guys and I haven't seen much problem around here that I
would contribute to dry yeast use. Now bottling (which Murphy's Creek plans
to do) is another story. Those small counts of critters can cause problems
when the beer is not stored and handled properly (which IS always the
case).

Subject: Re: RIMS, vent pipe, and channeling
In HBD 1130, Michael.Burgeson@Eng.Sun.COM (J. Michael Burgeson) writes
about a proposed RIMS system, and says:
> With a RIMS system, channeling during the mash would not be a
problem.
I am not sure this is the case. The purpose of the recirculation is to
evenly distribute both the heat and the enzymes/starches/etc. If
significant channeling is occurring, this distribution will not be as
efficient, thus reducing the potential gains from the recirculation.
> What I would like to propose is using a vent pipe, but running it >
outside the mash/lauter tun.
While putting the tube outside will certainly eliminate this as a
source of channelling, I am skeptical as to whether this vent tube is
worth having. My understanding of the compaction problem is that it is
due to the suction from the recirc pump. If this is so, then a vent
tube will not help (regardless of whether it is inside or outside the
vessel). The tube will merely act as a manometer, displaying the
suction inside the vessel as a drop in liquid height in the tube. The
exception to this is if the suction is great enough to drop the fluid
level in the tube below the level of where it enters the vessel, in
which case air will be sucked into the vessel from the tube. This will
"clamp" the suction in the vessel at its present value, not allowing it
to increase any further. However, (1) you may already have significant
compaction at this level of suction, and (2) air will be entrained into
your recirc stream, possibly causing loss of pump prime, and hot-side
aeration.
My suggestion is to use the vent tube, installed outside the vessel,
but use a clear tube so that you can observe the fluid (suction)
level. Find a level (by trial and error) where compaction does not
occur, and set your pump flow rate to maintain approximately that
level. (This would probably require constant monitoring, or better
yet, a closed loop feedback system.)
Another suggestion, which I throw out for discussion, is this: why not
recirculate _upward_ through the grain bed? It seems as though this
would reduce the compaction problem, as you are no longer creating
suction within the bed...
Disclaimer: My degree is in Chemical Engineering, so I am very
familiar with the physics involved here; however, I speak from
_in_experience, as I have not built nor used a RIMS system. I am
planning one, but will have to wait to get sufficient $$$ before I can
build one. Anyone from the Salt Lake area want to pool resources???
Good Luck,

>I am a semi-experienced homebrewer contemplating my first all grain
batch. I'm wondering though if I will be able to use an electric stove
to maintain the precise temeratures needed for a successful mash.
I think it is worth stating an opinion which other may choose to disagree
with.
Contrary to popular opinion and probably one of the many momilies that keep
extract brewers from taking the plunge into all grain is the perceived need
for precise temperature control for a "successful mash". If by a successful
mash we mean producing a good beer at a nominal extract yield, I suggest that
you can achieve that even if your mash temp wanders randomly between 150F and
160F for 30 minutes or more.
With the right equipment and attitude, the "plunge" into all grain really
becomes more like falling off a log.
The notion about precise temperatures is based on the theoretical action of
enzymes on starches which produce slightyly different amounts of different
sugars at various point in the temp range.
If that is important to a first time all grainer, I would be very surprised.
These details are important for acheiving nominially different character for
different styles of beer but I seriously doubt that very many home brewers
are capable of maintaining the kind of temperature control required to prove
the point.

Subject: Mashing on an Electric Coil Stove
Thanks to all who replied to my question regarding mashing on an
electric stove with limited heat settings. Sounds like it's not that
big a problem. The following is a short collection of replies:
>From Tim Fairclough
I mash in my oven and boil on the electric coil stove all the time. By
mashing in the oven I mean: setting my oven as low as it will go which
will hold a mash at 150 degrees perfectly. I stir ocasionally during the
mash period and heat the sparge water during the last half hour or so of
the mash period. I have done three partial mashes and one full mash this
way with great success (IMHO). I should mention I have only done
infusion mashes. Good luck.
>From Karl Sweitzer
I use a .25 inch thick plate of brass over my coil stove to more equally
distribute the heat. I found that I got coil burn marks in the bottom
of my thin boiling pot (even with extracts!).
>From Jason Goldman
I mash on an electric stove and I've been very successful. The trick is
not to be in too much of a hurry. In other words, if you are 10 deg shy
of your target temperature, don't turn the stove on red_hot to get it up
quicker. When I do ales, I heat my mash water to around 180 def F. Then
when I add the grain, it settles out to about 158 deg F. After stirring
in the grain so I achieve a good mash in, I take it off the stove and put
the lid on. If the temperature was too low (or if the mash temp drops),
then I put it back on the stove on hot/less hot for a while to raise the
temp. Grain is a very good temp buffer on its own.
> From Ed Hitchcock
If you're making a lager, you can do a decoction mash. Heat the
mash water to about 135-140F and add grist. Let rest 1/2 hr. Remove a
portion of the mash (grain and liquid) and bring that to a boil on the
stove and add back to the mash to raise the temp. You may want to do rests
at 149-145F and 159-155F, so you'll want to remove maybe 3 quarts or so
(I've never actually done a thick decoction, so I can't give you the exact
numbers) to boil. You can take small amounts and repeat a few times which
takes a little longer, but you won't cook too much of the mash, nor
overshoot your target temperature.
***************
I couldn't resist throwing in my $.02 on the Alcohol and other drugs
thread too. The only reason I see to outlaw the use of drugs is to
protect the public against people who use them. IMHO the government
should have no right to tell me what I can and can't do to myself, but
if I start affecting those around me I am beyond my rights. With that
in mind, I would say someone high on a stimulant would be more likely
to affect those around them and hence would be more dangerous.
Alcohol, being a depressant, slows people down. Although they can
still be violent and troublesome, I think the general opinion is that
they would not be such a threat to the public as someone on a
stimulant, hence less regulation.
I am opposed to regulation of *most* drugs (although I use no illegal
drugs by my own choice) and will never understand the arguments for
legalizing alcohol, but not marajuana (sp?).

Subject: oatmeal
How do other people incorporate the oatmeal into an oatmeal stout (or
other beer)?
I've made 3 or 4 batches, and previous to last weekend I had used
Quaker oats from the supermarket, and added them to the mash.
Last weekend it was easier to go the the natural food store and buy
rolled oats from the bulk bins.
I frequently taste the grain when the sparge is through, to verify that
it is tasteless. This is usually the case. This is confirmed by the
fact that animals (including birds when there are other food sources)
don't seem to be very interested.
However, last weekend, there was still definitely oatmeal flavor in
the "spent" grains.
I don't remember whether I've tasted the Quaker oats batches. However,
I donate my spent grains to a friend who uses them for
landfill/compost. He reported that there was definitely some animal
who had been eating around that batch.
Would I get better extraction if I cooked the oats before adding them
to the mash? Or is the flavor of the oats not really the point anyway?
Thanks,
Laura

Subject: A few questions about mashing...
I am planning to brew the following two batches this weekend.
1) Imperial Stout
Desired Yield: 5.5gallons@.1075
Estimated Extract Effeciency: 27 (pts*gal/lb)
Total Malt: 15.5
.5 lb Chocolate
.5 lb roasted Barley
.5 lb flaked (barley or red wheat)
14 lbs Klages
Method: Overnight single step infusion mash starting at ~155F (should
end at ~145F)
Sparge with ~5 gallons 180F water (No Mashout)
Boil 30 minutes
Hops:
Boil: 60 IBU Chinook (1 hour)
Flavor: 10 IBU Cascade (15 minutes)
Aroma: 1.5 oz Cascade (15 minute steep)
Immersion Chilled to 80F
Yeast: Wyeast Irish Ale (.5l starter from slant)
2) American Brown Ale
Desired Yield: 5.5 Gallons@1.045
Estimated extract efficiency: 27 (pts*gal/lb)
Total Malt: 9.25lbs
.5 lb 40L Crystal
.25 lb black Patent
.25 lb Chocolate Malt
.25 lb Flaked (barley or Red Wheat)
8 lbs Klages
Method: 2 hour single step infusion mash at 156F (should end at ~154F)
Sparge with ~5 gallons 180F water (No Mashout)
Boil 30 minutes
Hops:
Boil: 25 IBU Cascade (1 hour)
Flavor: 5 IBU Cascade + 5 IBU Willamette (15 minutes)
Aroma: .5 oz Cascade + .5 oz Willamette (15 minute steep)
Immersion Chilled to 80F
Yeast: Steinbart's Brown Ale (.5l starter from slant)
And, I have a few questions (imagine that!):
1) In the past, I have made my own roasted barley by toasting milled 2
row klages at 350F for 15 minutes. The beer came out *very* cloudy.
Any ideas how to avoid this?
2) When a yeast's attenuation percentage is listed, is that
%(fermentable sugar) or %(total sugar)
3) How can one determine the fermentable/unfermentable ratio *prior*
to mashing? What percentage fermentables can I expect at 158F mash?
At 148F mash?
4) I have never gotten the iodine test to go negative in less than 2
hours in the 153F-156F range. The top of the mash may test negative
for starch, but upon stirring, the test will go positive. I always
wait untils the stirred mash tests negative. I also tend to get very
alcoholic, thinner bodied ales. I would prefer a fuller bodied lower
alcohol (4.5% desireable) brew. Should I be stopping the mash before
the test goes negative?
5) I prime with 1.5qts 1.040 sweet wort for bottling. THis is roughly
equivalent to 3/4cup corn sugar. Should I increase this for the stout
due to the high gravity?
Phew...
Thanks in advance,
Drew

Subject: Long distance dispensing
I haven't yet resolved with my spouse the issue of space in the kitchen
fridge for a beer keg, but I thought up this compromise the other day:
How about putting the keg and CO2 tank in the basement and running a 1/4
inch line up through the kitchen floor into the fridge, then through a
steel cooling plate and a tap? This way, a single glass of beer would be
cooled enough, and for a group, you could put the cooling plate into a tub
of ice.
My major concern is that I'd have to crank up the pressure to get a good
flow through about 12 feet of tubing, then the brew might be two gassy when
it's finally dispensed.
I'd appreciate hearing from folks who have used a long line between the
tank and the tap, and just what kind of problems you encountered.

Subject: RIMS
In HBD1130 Michael Burgeson mentioned possible differences in efficiency
between a "conventional" sparge and a recirculating sparge ala RIMS.
I have used both methods, and both worked OK with virtually no difference
in efficiency. So use whichever method you're comfortable with.
about channeling:
I also have never observed any channeling in my mashes, but to be
honest, I've never really been looking specifcally for that. I'll look
a little closer next time.
about vent tubes:
The vent tubes I have used in the past worked very well for minimizing
mash compaction due to suction from the pump. The tubes become less
effective as the quantity of grain increases. I'm not sure, but there
probably is a point where sheer weight of the grain is a factor.
When the vent tubes do suck air, there is foam generated, and HSE could
be a factor. HSE never seemed to be a problem for me, but it could be
a concern in a RIMS setup. So far,
I like my current method ( described later ), but being an obsessive
tinkerer, wait till next week. :)
On my last two batches, I have used the vertical screen tube in the middle
of the mash until sparge time, when I removed it and recirculated the
wort at a slow rate ( no heat ), and then performed a "conventional"
sparge. On the first batch with the tube, I simply had the copper return
tube with a few holes drilled in it submerged below the surface of the
wort. On the last batch I had a 3/8" copper tube ( again with holes
drilled in it ) coiled in a spiral around the screen tube and spaced
approximately halfway between the screen tube and the side of the mash
tun. This setup gave a very consistent temperature in all parts of the
mash, with no compaction at all.
As Bob Jones correctly pointed out, the ultimate test of a RIMS setup
is a large batch using predominately wheat malt. I plan to try that
sometime this summer.
Cheers,
Alan

Subject: Refrigerator Idea
A few months ago, I successfully staged a coup de etat and gained possession
of the family freezer, hooked it up to my airstat, and brewed happily it
it while using my other beer fridge for serving temperatures. Unfortunately,
after a spousal counter revolution combined with decreased availbility of
food, the freezer is now a freezer again .. with food in it instead of beer.
Oh well.
Now I have a dilemma with Texas summer coming. I need a 48-50F fermenting
environment, and a little lower temperature for serving.
I have an idea I have been considering:
With the airstat set at 49F, and the plastic freezer baffles set for
minimum freezer temp, I placed a container of water with a thermometer
in the freezer compartment. The water temperature stays at about 34F, and
has not frozen after about 3 days inside. The temperature inside the rest
of the fridge is 49+-2F
Since the fridge holds 4 5gal soda kegs, I want to have two fermenting, one
aging, and one serving. My idea is to construct the equivalent of a
jockeybox inside the freezer compartment. ( A cold plate would be nice,
but they are kind of pricey ) The beer from the serving keg would pass
through the coil and be chilled some, depending on how long the tube
was, flow rate, etc.
Has anyone tried anything like this?
Is this a crazy idea?
Any comments are welcome.
Cheers,
Alan
