Subject: IIPA IBUs

In addition to the limit of how many IBU's you can get into a beer, there is
also a limit to the sensory perception of bitterness. I have heard this
limit stated as 65 IBUs, but have not tested this myself and had always
believed the limit to be higher. Of course, this is only the perception
limit for bitterness, not hop flavor/aroma.

Subject: Iso-alpha acid solubility

The maximum solubility of iso-alpha acids is not dependent on
the maximum percent utilization of iso-alpha acids. If the maximum
solubility is 90%, which I am not questioning, then one should
be able to achieve this regardless of the efficiency of utilization.
And it doesn't matter how one performs the additions. It is dependent
on the properties of the solvent, temperature, and perhaps the
concentration of other solutes. This list of factors is not
exhaustive, but it doesn't include percent utilization.

Subject: Re: IIPA IBUs

For what it's worth, I built a saturation limit into my recipe
spreadsheet. I don't have access to my formulas right now (I'm still
in on a hospital computer, so I can't download anything), but you can
view them here if you know how to trace formulas in Excel:

https://sites.google.com/site/republicbrewpub/

The name of the file is Recipe_Gallons.xls. I believe my formulas
follow the Tinseth model below 65 IBUs (modified to allow positive
bitterness contributions of late kettle and whirlpool hops), and then
linearly decrease the effectiveness of alpha acid additions so the
projection passes near one of the Deschutes data points (80ish actual
IBUs for a calculated 240ish IBUs?). I don't remember if I included a
max IBU limiter, but the amount of hops needed to get to the Deschutes
example would be absurd. I also did something with the Sierra Nevada
hop school results that were printed in Zymurgy or BYO a short while
back, but it may have just been a spot check of my calculations.
Considering the massive dependence of hop utilization on brewing
equipment and procedures, as well as the fact that perceived
bitterness is only loosely correlated with IBUs (and has its own
saturation limits), I'm comfortable with ballpark accuracy until it
can be improved upon by better experimental data.

Subject: Re: IIPA IBUs

Hi All,

Interesting discussion in the last few HBDs about IBUs and solubility
limits of alpha and iso-alpha acids.

I've heard many times that the limit is "about 100 IBUs". I'm not sure of
the source for this and definitely don't have references to back it up.

However, I made an American barleywine many years ago that had a predicted
207 IBUs (Tinseth formula). It measured at 115 IBUs using the ASBC method
and a 1:1 dilution with distilled water. The measurement was made about 13
months after pitching the yeast.

FWIW, YMMV.

Subject: RE: Sun-dried hops?

Doug,

I've never dried my hops in the sun, just laid them out on old window
screens on saw-horses (good air circulation) in the shade. I've used these
with great success for flavor/aroma additions. Not for bittering since I
don't know the alpha acid content to be able accurately calculated IBUs. I
did however make entire batches with fresh picked hops (Harvest Ales) and
that worked great. The other use for the hops was for my lambics. Just
left all the hops in an open grocery bag in my basement for a year or more.
Yes, they really did smell cheesey. That worked well also. Good lambic
with those hops.

From: mossview5 <mossview5 at gmail.com>
Subject: Re: IIPA IBUs

Many brewers use the various hop utilization formulas to estimate their
bittering level in their beer. Many of those formulas provide acceptable
estimates of bittering (iso-alpha content in mg/L). Unfortunately, those
formulas don't adequately address the solubility limit of alpha acids and
iso-acids in wort and water.

As has been alluded to in previous posts on this subject, there is an
alpha acid solubility limit. AJ's post and the Deschutes Brewery blog both
provide the implication. I can add that there are several other
peer-reviewed journal articles that specifically point out that both alpha
acids and iso-alpha acids have limits in solution.

Probably the most definitive work to date on this subject is from Malowicki
and Shellhammer. They were conclusive in establishing that the maximum
solubility of alpha acids is about 90 mg/L. They also established that the
maximum conversion of alpha to iso-alpha is about 75 to 85 percent of the
alpha acid content. That points to a maximum iso-alpha content of about
80 mg/L which is equivalent to 80 IBU. So, no matter how much hop
volume and alpha acid content you throw in a wort, the maximum IBUs will
be about 80.

Fortunately, there are other bittering components from hops and other
wort components that add to the perception of bittering. Unfortunately,
there is little research into this area since most beers are crafted far from
the alpha acid solubilty limit. Components like beta acids, phenols, and
tannins add to the bittering perception. So there can be a more bitterness
perception, it just won't be from iso-alpha acid content.

So next time someone says that they bittered to some astronomic level,
you can just snicker. If they were aiming for a super bitter beer, the way
to really get there is to reduce the gravity of the brew to enhance the
BU:GU contrast. By definition, an IIPA is going to be less bitter than a
similarly bittered IPA or PA.

Subject: Re: IIPA IBUs

[Invoking janitorial privilege to reply early...]

Martin writes that because there is a solubility limit for alpha-acids
of 90mg/liter, and because only 75 to 85 percent of the alpha-acids are
converted to iso-alpha acids, that IBUs are capped at about 80.

That would be true if there was a strict sequence, without overlap of
1. Dissolve alpha-acids in the wort.
2. Convert dissolved alpha-acids to iso-alpha-acids.

But that's not what happens in the brew kettle. Instead solution of
alpha-acids overlaps with conversion of dissoved alpha-acids to
iso-alpha-acids. Thus, the iso-alpha-acid concentration can exceed the
limit imposed by alpha-acid solubility.

Consider this thought experiment: add enough hops to dissolve 80mg/ml of
alpha-acids, and boil to convert 75% of these to iso-alpha-acids. There
will now be 60mg/ml of iso-alpha-acids and 20mg/ml of alpha-acids. Now
add more hops to bring the dissolved alpha-acid content back up to
80mg/ml. Boil again. More iso-alpha-acids will be produced (possibly as
much as another 60mg/ml).

There are undoubtedly other limiters in play, though. There is a
solubility limit on iso-alpha-acids, which I had thought was about
100mg/ml. Conversion of alpha-acids to iso-alpha-acids may be inhibited
by the presence of iso-alpha-acids. Also, the solubility of alpha-acids
may be depressed by the presence of iso-alpha-acids.

But I am pretty sure that the limit is not 80. I know that Stone Brewing
claims to have measured Stone 13 to be very close to 100 IBUs (they list
it at "90+" on the bottle). Best citation I can find online for this is
at Stan Hieronymus's blog, Appellation Beer,
http://appellationbeer.com/blog/how-many-ibu-about-one-hundred/

There's also an interesting comment there from Stone brewmaster Mitch
Steele about the solubility and thus the IBU level decreasing as the
beer becomes more acidic during fermentation.

Subject: Re: IIPA IBUs

Nick brings up a good point about the measurement of iso-alpha acids.
The differences between calculated and measured IBUs in this article
by Deschutes Brewery are stunning (although I don't know the formula
they use for calculated IBUs...):

http://www.deschutesbrewery.com/blog/2009/02/13/lies-damn-lies-and-statistics/

Well, I hope it's the correct article. I'm in a hospital right now
and can't view websites with the word 'alcohol' in them. Anyway, late
and dry hopping with high-alpha varieties are great ways to build
massive hop flavor and aroma. Adding the majority of your late hops
at flameout and waiting a half hour before cooling your wort will help
a lot too; DMS isn't really a concern at the boiling rates of most
home breweries (I lose 15-20% of my wort in a 1-hour boil compared
with 5-10% seen by small craft breweries, who typically leave their
worts hot for a half hour to whirlpool). Last year, I was lucky
enough to attend a presentation on hopping methods by the quality
director of Rock Bottom. They performed a hop experiment across their
entire organization, and I found it hugely informative. Here's my
take on their results:

From: "A.J deLange" <ajdel at cox.net>
Subject: IBUs

It might be well to recall the introduction to the ASBC MOA for
determining beer bitterness by the international (IBU) method (the
method most accessible to home and craft brewers):
"Reports of the Subcommittee on Determination of Isohumulones in
Beer... indicate that bitterness units (BU), as determined in Method
A below, express the bitter flavor of beer satisfactorily..."
I doubt very much that the committee studies beers of over 100 IBU in
coming to that conclusion. Whether they did or didn't note that no
claim is made that the measurement accurately represents perceived
bitterness.

The method itself involves extraction of the beer with gasoline and
measurement of the absorption in 1 cm at 275 nm. The result is
multiplied by 50. Assuming the instrument is linear up to A = 3.0 the
maximum it could measure would be 150 IBU. Most analysts would
probably prefer to keep readings to no more than A= 2 for an
instrument rated to A = 3 so that would imply that perhaps 100 IBU
would be the upper limit.

The instrument does not have to be the limiting factor, of course. One
could simply dilute the beer 1:1 with DI water before doing the
extraction. In such a case a reading of A=2 would correspond to 200 IBU.

I'd have some questions about the solubility limits of isohumulones
but I really don't know what it takes to saturate a solution with
them. Nor do I have any feel for what it would take to saturate one's
palate. I know I wouldn't like a beer that bitter!

Subject: Hop Flavor and Aroma in High Gravity Beers

Paul Hethmon asks about some ways to improve his aroma and flavor
profile on high gravity beers:

I did some initial experimenting of my own this summer with my own
formulation of a clone of Oskar Blues
Brewery's "Gubna" beer. It is a very malty high gravity brew with lots
of hop flavor without that grassiness
that I have found in previous attempts to throw a lot of hops into the
boil to get up into that 100+ range of
projected IBU's. In talking with some of our club members here in
Nashville, several recommended that I
use most of my hops at the very end of the boil. The Oskar Blues website
indicated that this particular beer
uses Summit hops, one of the newer high alpha varieties that are
becoming available to homebrewers these
days. So I did just that, and ended up adding 1 ounce of Citra hops (AA
of 11%) at the beginning of my 10 gal batch boil because I needed
some whole hops to work in my kettle to help with the run-off and the
Summit hops were pellets. I ended up
adding 8 oz. of Summit pellet hops (AA of 16%) at the 10 min. mark
before shutting off the burner. Now, granted, this ends
up being a very expensive proposition, but the Pro-Mash calculation on
the IBU's gave me 78 IBU's on an OG of 1.078.
I ended up serving the two kegs at the Music City Brewers' Festival, and
even had some cans of Gubna to let
people do a side by side tasting, and it was pretty close in capturing
that beer's profile. Several people actually liked
mine better - probably because it was a lot more fresh! It was very
malty (it uses some rye and
dark Munich in the mash, I believe) and actually very hoppy, but not a
lot of harsh bitterness. Just what I hoped for.
But as I said, this costs a lot in terms of the amount of hops you have
to use, but it is worth trying at least once
to see the difference this makes with some of these high alpha hops.

I would expect that the little amount of Fuggle and Cascade hops you are
adding at the end will be "underwhelming" and "overwhelmed" by
the more intense hop bitterness from your Zeus hops at the beginning of
the boil.

Hey, Paul, I see that you are planning to come to our competition in a
few weeks. We're looking forward to seeing you
then! We can talk more at the Beer Dinner. Wish I still had some of that
Gubna clone to share with you.

Subject: RE: imperial IPA ibu

There is a threshold limit to what the human body can detect for IBU's.
If you really want to get the most bang for your buck with hopping use enough
hops for 1/4 of your bittering at 60 to 90 minutes then add 1/2 of the
remainder
during the final 20 minutes. This will give you the best results for
flavor. Then
add the last 1/4 at flameout. Good luck.

From: "Mike Patient" <mpatient at rta.biz>
Subject: RE: IIPA IBUs

Paul mentioned he got 196 IBUs from his IIPA in previous attempts. How is
this being measured?
My understanding of IBUs was that above 100 it is very hard to tell the
actual bitterness. Most human palates can't differentiate past that, and
most algorithms break down past that. Was this really measured, or was it
just an overkill of hops? (I bet it tasted gooooood though)

As for the hop aroma, I don't think the 20g at 5 and flameout is enough. I
do that with my APA and if I don't dry hop, it doesn't have much of a hop
aroma. I would cancel the last flameout addition and double it in the
secondary as dry hop, however, if you don't want to dry hop, how about
making a hop tea and adding that after fermentation? It won't make a mess,
and you'll get some aroma and possibly flavor out of them. I think 114 is
an attainable goal.

The problem is that any short courses are not likely to be sufficiently technical
and any good technical programs are multi-year degree programs.

Heriot-Watt offers an MSc degree in brewing and distilling by distance learning
from their International Centre for Brewing and Distilling.
http://www.postgraduate.hw.ac.uk/courses/view/119

Doemans in Germany has a similar program, but I am not aware of distance learning.

Perhaps you could start by picking up a few good undergrad courses in the basics,
physical chemistry, lab methods, microbiology, biochem.

I did one a year ago with an OG of 82 and 196 IBU based on some
recommendations that I couldn't go high enough. In the end I don't
think I went too high, but it was mostly bitterness and not much
aroma or distinctive hop flavor. I did EKG at 5 minutes left in the boil

So, for this one, I'm shooting right now for an OG of 80 and IBU of
114. Main bitterness is planned from from whole leaf Zeus hops. I've

20 g of Cascade at 5 minutes out and another 20 g at flame out.

Subject: DudaDiesel Followup

I posted a couple of weeks ago about experiences with the plate chillers
sold by DudaDiesel (www.dudadiesel.com). Based on the feedback
here and our local club list, I went ahead and purchased one.

To recap, the Shirron plate chiller is about 0.4 sq meters, the Blichmann
is about 0.6 sq meters. I ended up purchasing the 0.69 sq meter model
that Duda sells:

http://www.dudadiesel.com/choose_item.php?id=HX2330

$146 delivered.

This past Saturday, our local club had a brewout at my house and
I got to use it for the first time. My tap water is flowing at about 76 right
now. Using a gravity feed to the plate chiller and then to the fermentation
bucket on the floor, I was able to chill the wort to 80 degrees in around
10 minutes. I didn't measure my chilling water flow, but it was running
about half open.

So, I'm happy with my purchase.

In corresponding with the guy who owns Duda Diesel, he felt the
chiller I bought was 70% oversized. He also felt the shape of the chiller
was important for the efficiency of it as well. I had asked that question
since if you go by surface area alone, he had a few other models a bit
cheaper.

So I hope that's useful to someone here.

The bb sized buds/flowers you noticed are indeed male hop

They are sterile so no worries. They will not affect anything and

Subject: Male Hop Flowers?

I noticed a few of the these little (about BB size) flowers
on my Chinook hops last year but noticed them on my Cascades
this year. They may have been around on both but I just didn't
see them. Has anyone else seen this? These are on female hop
plants and I am getting normal female hop cones on the rest of
the plant.

Everything I have found on the internet indicates that the male
flower develops in early June and the female a bit later. I don't
see any evidence of any cones going to seed so I expect it is just
an anomaly but was wondering if anyone else has noticed this or
has additional info that may explain what is going on. I haven't seen
anything on any other varieties I grow just the Chinook and

Subject: Brewing Science Classes

Anybody familiar with any type of listing for brewing science classes?

I don't mean the LHBS stuff, I mean more like what Siebels or UC Davis does,
for those of us that have jobs and can't take the time to do the weeks and
semesters long full time stuff.

I have seen the MBAA stuff in Wisconsin, and Siebels and UC Davis, but I am in
PA, and am searchng for something I can do either on a night class deal or
online (I prefer the classes, I am on of those that learn better that way).

I know this is a long shot, but you never know unless you ask!

Subject: Fermentability of maple syrup

In an earlier post in this maple syrup thread, I pointed the readers to a site
that said maple syrup was about 65% fermentable. I found another site saying
maple syrup was 75% fermentable, but this same (second) site said that corn
sugar and table sugar were each only 80% fermentable. I know something must be
wrong here.

In today's HBD, Matt Falenski pointed us to a Maple Wine in which he used maple
syrup as the only fermentable diluted to 1.110 specific gravity that fermented
to a final specific gravity of 0.98, proving that the maple is essentially 100%
fermentable (as is cane sugar and table sugar). Am I missing something here?

Subject: Maple Syrup

The one sample of maple syrup, from Stanstead, Quebec (right on the
Vermont border) that I measured came out at 65.98 Bx with a density of
1.3225. Thus a liter of it would weigh 1.3225 kg and contain 872.6 grams
of "sucrose". Presumably, all this is fermentatable so just do the
conversion to whatever units you like and treat it as ordinary sugar.

Subject: Re: Fermentability of maple syrup

I actually was amazed at the fermentability of maple syrup.
I did not measure the Brix of the syrup before using, I'll do that
next year though. (Anything above about 66-67 Brix starts to crystallize,
anything below is too watery) It started out at 1.111, and finished
out at 0.984. I've never had anything go that low before!

If my refractometer calculations and corrections were correct it should
have been about 16.96% ABV. When I tested it on our Anton Paar alcohol
meter at work, it gave me an ABV of 16.39% so it was very close.
I backsweetened it before I took any more readings and ended up with a
final SG of 1.008.

From: <stihlerunits at mosquitobytes.com>
Subject: Maple Syrup - Part II

After I posted my question regarding the extract of maple syrup I got to
thinking that it should really not be all that hard to calculate it
based upon the information available. I was going to cancel my post but
alas it was too late.

I appreciate all the responses I got for my question.

At any rate, I came up with a value of 32-33 gravity units per pound per
gallon which is similar to what other folks have noted.

I believe I calculated the values correctly but....

At any rate, I'd appreciate it if folks would check out what I have and
see if my logic (or arithmetic) is off somewhere.

By definition maple syrup contains 66-68% sugar. The 68% is an end
member since I believe the sugar crystalizes into maple sugar that
concentration.

At any rate, using any number of online Brix/Specific Gravity converters
you would find that 66% and 68% correspond to specific gravity values of
1.329 and 1.342 respectively.

I'll just do the 66% one as an example:

(1.000 ml/1.329 g) x (453.59 g/lb) = 341.30 ml/lb

(341.30 ml/lb) X (1.00 fluid oz/29.57 ml) = 11.54 fluid oz/lb

34% or 3.92 fluid oz. of which is water.

Now converting to weights:

66% of one pound (i.e. 16 oz.) of maple syrup is 10.56 oz by weight of
sugar and the remaining 5.44 oz. by weight is water.

When one adds one pound of maple syrup to one gallons (128 oz.) of water
you end up with 128 oz. + 3.92 oz. = 131.92 fluid oz. of water and 10.56
oz. by weight of sugar.

Therefore, the resultant sugar content is: 10.56 oz./131.92 fluid oz. =
0.0800 or 8.00% sugar.

Once again using your trusty Brix converter you find this corresponds to
a value of 1.032.

Therefore, for 66% maple sugar the extract is 32 gravit units per pound
per gallon.

Doing the same calculations for 68% one finds that 11.40 fluid oz. of
such maple syrup is one pound and the corresponding extract is 1.033 per
pound per gallon.

Therefore, the extract of maple syrup should be 32-33 gravity units per
pound per gallon.

Please let me know if I've gone amiss somewhere.

Cheers,

Subject: Maple Syrup

In reply to Scott Stihlers question about predicted extract
of maple syrup...

At a minimum, maple syrup has a 66% sugar content (66 Brix)
but can have more. It's SG is roughly about 1.331.
The darker the color, the stronger the flavor, too, so
keep that in mind.

I've never done a beer with maple syrup yet, but I have
done a few maple wines,
check these out if you're interested...

Scott Stihler asks for the potential extract of maple syrup. The value I have in
my homegrown software is 28.9 units*gallons/lb with a color of 15 degrees
Lovibond/38.6 EBC, but we all know maple syrup comes in lots of different colors
and who knows how variable the specific gravity is.

One can simply measure it with a hydrometer by diluting it in a precise manner
and calculating the gravity based on the dilution. I read that it is about 65%
fermentable at the following site:

Maple syrup has an extract of about 1.045 pounds/gallon, very similar
to the average as honey.

Subject: Ancient Nubians Drank Antibiotic-Laced Beer

People have been using antibiotics for nearly 2,000 years, suggests a new
study, which found large doses of tetracycline embedded in the bones of
ancient African mummies.

What's more, they probably got it through beer, and just about everyone
appears to have drank it consistently throughout their lifetimes, beginning
early in childhood.

While the modern age of antibiotics began in 1928 with the discovery of
penicillin, the new findings suggest that people knew how to fight
infections much earlier than that--even if they didn't actually know what
bacteria were.

Subject: Extract of Maple Syrup

I was wondering if anybody happens to know the predicted extract of
maple syrup.

I was thinking of brewing a maple syrup porter or stout but I've been
unable to find a value for the extract in terms of specific gravity per
pound of maple syrup per gallon of wort.

Cheers,
