-
And a Cluster
it Was !
-
- Eight
teams converged on the WeekEnd Brewer Saturday September 13th,
2008 for the 5th
Annual Ted Warren Cluster Brew Competition.
-
- This
year Competition Coordinator William Spiesberger decreed that all
beers brewed at the competition were required violate the terms of
German Purity Law of 1516 otherwise known as the Reinheitsgebot.
Accordingly, a variety of non-barley brewing ingredients could be
seen at the competition including candy bars, blueberrys,
raspberrys, ginger root, honey, and lots of sugar and spices.
Reports of explosive fermentations circulated for a least a week.
-
- It
has also been rumored that a radical sect of JRHB brewers have
staged a Counter-Cluster Brew and are producing beers with
unorthodox ingredients such as corn (yawn).
-
- This
all points to a very beery club Christmas Party which will be
hosted by Mike and Bobbi Lang in December where the winning team
will be determined through consumption (and a popularity vote).
-
- The
name of the winning team will engraved on the Cluster Brew Mash
Paddle which hangs at the WeekEnd Brewer for all to see, and the
team will have exclusive bragging rights for a full year.

Spiesberger gave a recap of this years 15th
Annual Dominion Cup competition, which was held on August 30th
at Capital Ale House. This years competition included 153 entries,
at least one entry in all 23 BJCP categories, entries in 63
different subcategories, and entries from 62 different brewers from
12 states. William thanked Capital Ale House for all their help,
and the judges and stewards who participated. William reminded the
club of the CASK sponsored competition scheduled for November 15th
in Portsmouth and urged members to enter beers and to volunteer as
judges and stewards.
-
- The
5th
Annual Cluster Brew, after some discussion was confirmed as
scheduled for September 13th
at the WeekEnd Brewer.
-
- Steve
Severtson then gave an excellent and thorough presentation on how
to brew Oktoberfest/Marzen beers which was followed by Ted Smith
who presented several Oktoberfest beers for the attendees to sample
and comment on which included Paulaner, Hacker Pschorr, Spaten,
Hofbrau, and Sam Adams. Thanks to both Steve and Ted for a great
presentation.
-
- Robert
Doucet then conducted yet another great club raffle.

Short on hops
-
- Because the beer-making
ingredient is hard to come by, these home brewers are adding a new
hobby to their list: gardening.
-
- By Lindsey Nair; The Roanoke
Times
-
Tuesday, September 02, 2008
-
- Chris Arthur keeps a blue
binder beside his cash register. It holds a four-page laminated
list of hops.
- Arthur used to be able to order
dozens of different kinds of hops for his Roanoke store, Blue Ridge
Hydroponics and Home Brewing. Recently, he ordered 12 varieties and
just three were actually available.
-
- Arthur and his wife, Fran, had
hoped to sell 80 pounds of the beer-making ingredient in their tiny
Williamson Road store this year. But a combination of factors,
including bad weather and a struggling economy, has driven prices
so high in the past year that the Arthurs aren't sure they could
afford the inventory anyway.
-
- "It
is a shortage situation as well as a cost increase situation,"
said Julia Herz, spokeswoman for the Brewers Association in
Boulder, Colo. "Many factors all came into play in the global
market to affect hops all at once." As a result, retail stores
and online suppliers like the Arthurs have imposed restrictions on
the amount of hops a customer can buy at one time. It is a move
that has driven home brewers in Roanoke and beyond to add a new
hobby -- gardening -- to their list.
-
- Already
known as an adventurous bunch, these brewers are planting hop vines
thousands of miles from the Pacific Northwest, where all commercial
hops in the United States are grown. That's not to say that hops
cannot be grown in Virginia. But with the amount of attention they
require, some wonder if it's worth it.
- In
the decade or so before 2007, there was such a surplus in hops that
farmers were partitioning off their acreage for other uses, Herz
said. Global beer production was up 3.5 percent. Then, in October
2006, a huge warehouse fire in Yakima, Wash., destroyed $3.5
million to $4 million worth of hops, or four percent of the
nation's total yield. Overseas, a combination of droughts, flooding
and hailstorms were wreaking havoc on crops, but the European
dollar was soaring, allowing Europeans to "snatch up U.S. hops
at a cost advantage," Herz said.
- Ethanol
production increased demand for corn, luring some American farmers
away from hops and driving up the price of grain, another important
ingredient in beer. Though industrial brewers, who buy hops on the
futures exchange, were somewhat protected from the shortage,
microbreweries and home brewers were left in short supply.
- Hop vines produces cone-shaped
flowers, which are used during the brewing process to impart
bitterness and aroma into the beer. Different hops produce
different results in the beer, so home brewers who like to
experiment prefer to use a variety of hops.
- Bryan Summerson, president of
the Star City Brewers Guild in Roanoke, said hops he once bought
for 99 cents per ounce have tripled in price. Some are even up to
$7 or $8 per ounce, he said, while others are not available at all.
-
- The
Arthurs have chosen to limit hops sales to five ounces per customer
per visit. Five ounces, however, is not enough for some of the
hoppier beers, which have been growing in popularity over the
years. Also at the Arthurs' store, customers must buy other
beer-making ingredients to prove they are not buying hops so they
can hoard them. Chris Arthur said it doesn't feel good to restrict
their customers, but they have no choice.
- "We
can't replace what we have quick enough and we really want our
regular customers to be able to come in," Arthur said. Online
beer-making supply sites have taken similar measures. For instance,
The WeekEnd Brewer
has a restriction of five ounces per week, and customers must buy
malt as well. "We may have to stretch our stock for 12 or more
months," the Web site states. "This will affect every
brewer in the world so please don't feel like we are picking on
you."
-
- This
spring, Summerson retreated to his Southwest Roanoke back yard with
five scraggly, paper towel-wrapped hop roots called rhizomes. He
buried the Fuggles rhizome beside the shed. The other varieties --
Crystal, Chinook, Centennial and Cascade -- were planted in a
square formation in the grass. To his wife Jenny's dismay, he then
constructed what she calls "football goals" made out of
white PVC pipe, which stick out of the ground beside the shed. Each
post is strung with twine from top to bottom so the vines can
climb. Fuggles took off, clawing its way to the roof of the shed
and providing Summerson with a bag full of cones, the hops flowers.
Chinook struggled to produce one handful. The rest are growing,
albeit slowly, and haven't produced any flowers.
- It
commonly takes two to three years to get cones off a hops plant.
Patrick Kennerly, who preceded Summerson as the brewers guild
president, has a 5-year-old vine that produced well only one year.
"Unless you are able to get out there and water them every
day, they get curled leaves and brown flowers," Kennerly said.
"The only way to beat it is if you can just be right on top of
it." Virginia hops are susceptible to mildew and pests such as
Japanese beetles.
-
- Home
brewers who get the hang of caring for their hops may eventually be
able to produce enough to make a couple of batches of beer.
Realistically, though, the home brewer who likes to experiment with
different recipes and brews more than a dozen or so times per year
will never be self-sufficient in the hops department. "I brew
too much," Kennerly said. "And there are probably 25 or
30 varieties that home brewers use routinely." At best, these
hobbyists can hope to supplement their hops needs with the cones
they are able to produce in the back yard. But that hasn't stopped
them from trying.
-
- "Across the entire
country, the demand for hop rhizomes is up," said Janis Gross
of the American Home Brewers Association, a division of the Brewers
Association in Boulder. "When they are available, they have
been snapped up almost immediately."
-
- Gross,
a home brewer herself, has recently had to spend more time creating
recipes for the association's journal, Zymurgy. She knows she can't
invite readers to make a beer with unattainable ingredients. So,
until the hop supply makes its slow climb out of the basement,
which some experts believe is starting to happen, home brewers will
have to start experimenting even more. They can do that by subbing
in different hop varieties in place of those that are not
available.
-
- Web
sites such as MoreBeer and Austin Home Brew Supply have added
substitution pages for customers who want to make a beer but can't
find the specific hops. Another option, Gross said, is trying out
other herbs, spices or additives that provide a bittering effect in
the beer. Historically, spruce tips were used when hops were not
available. But hops also act as a preservative, so hops-free beers
can be less stable.
-
- The
Star City Brewers Guild is embracing the challenge, Summerson said.
For their quarterly competition in September, members are required
to use some newer varieties of hops that are easier to obtain, such
as Palisades or Glacier. And even during this shortage, Summerson
said, the guild has suffered no lack of interest. In fact, the
44-member club has actually grown over the past year. "We've
had a lot of new members in the past few months," he said.
"Compared to buying beer in the store, even with hops the way
they are, it still comes to like 39 cents per bottle."

-
- 7B. California Common Beer
-
- Aroma:
Typically showcases the signature Northern Brewer hops (with woody,
rustic or minty qualities) in moderate to high strength. Light
fruitiness acceptable. Low to moderate caramel and/or toasty malt
aromatics support the hops. No diacetyl.
-
Appearance:
Medium amber to light copper color. Generally clear. Moderate
off-white head with good retention.
-
Flavor:
Moderately malty with a pronounced hop bitterness. The malt
character is usually toasty (not roasted) and caramelly. Low to
moderately high hop flavor, usually showing Northern Brewer
qualities (woody, rustic, minty). Finish fairly dry and crisp,
with a lingering hop bitterness and a firm, grainy malt flavor.
Light fruity esters are acceptable, but otherwise clean. No
diacetyl.
-
Mouthfeel:
Medium-bodied. Medium to medium-high carbonation.
-
Overall
Impression: A
lightly fruity beer with firm, grainy maltiness, interesting toasty
and caramel flavors, and showcasing the signature Northern Brewer
varietal hop character.
-
History:
American West Coast original. Large shallow open fermenters
(coolships) were traditionally used to compensate for the absence
of refrigeration and to take advantage of the cool ambient
temperatures in the San Francisco Bay area. Fermented with a lager
yeast, but one that was selected to thrive at the cool end of
normal ale fermentation temperatures.
-
Comments:
This style is narrowly defined around the prototypical Anchor Steam
example. Superficially similar to an American pale or amber ale,
yet differs in that the hop flavor/aroma is woody/minty rather than
citrusy, malt flavors are toasty and caramelly, the hopping is
always assertive, and a warm-fermented lager yeast is used.
-
Ingredients:
Pale ale malt, American hops (usually Northern Brewer, rather than
citrusy varieties), small amounts of toasted malt and/or crystal
malts. Lager yeast, however some strains (often with the mention
of “California” in the name) work better than others at
the warmer fermentation temperatures (55 to 60˚F) used. Note
that some German yeast strains produce inappropriate sulfury
character. Water should have relatively low sulfate and low to
moderate carbonate levels.
-
- Vital Statistics:
-
OG: 1.048 – 1.054
-
IBUs: 30 – 45

-
- California Common or “Steam
Beer” History:
- California
Common or “Steam Beer” was originally produced in
California (San Francisco) from the mid-1800s to the mid-1900s
using a brewing method that utilized lager yeasts at ale
fermentation temperatures. Mechanical refrigeration was not
available at the time, and cold water supplies or ice were not
readily available to that area, which originated an alternative
brewing process out of necessity, likely just on the heels of the
Gold Rush. It was considered an inexpensive and low-quality beer,
as shown by references to it in literature of the 1890s and 1900s.
By 1891 a mug of steam beer generally cost five cents in San
Francisco, and bottled lager beer was three times as expensive. An
1893 article in Western Brewer magazine dryly noted that steam beer
was "not a connoisseur's drink." Most readers of that
period understood that steam beer drinkers were creatures utterly
without taste and refinement (and you thought a clear bottle 40oz
Hurricane was a new phenomenon).
-
- All
that said, Ray Daniels in his book Designing
Great Beers
notes that many of the period brewers used all malt formulations
and that the beer was likely highly variable in quality. “Given
the young age of the beer when delivered to the saloon, as well as
the sometimes sizable increment in kraeusen, the flavor of these
beers probably changed from day to day even before they were
tapped.”
-
- Wahl & Heinus’
American Handy Book of Brewing and Malting (1902) describes
California Steam Beer as “a very clear, refreshing drink,
much consumed by the laboring classes.” “Malt alone,
malt and grits, or raw cereals of any kind, and sugars, especially
glucose, employed in the kettle to the extent of 33 1/3 percent….
Roasted malt or sugar coloring is used to give the favorite amber
color of Munich beer.” Possibly to help make it more
drinkable, many brewers seem to have hopped it very heavily. Heavy
hopping may also have helped maintain stability for a beer stored
in a warm climate without refrigeration. There are no records of
the type of hops used, but it's reasonable to conclude that the
bulk of the hops would have been grown within California, and the
primary variety grown in that period was Cluster. The hopping rate
was approximately equivalent to two ounces of hops for a
five-gallon batch, although what the alpha-acid content of the hops
at that time was is questionable.
-
- Period
brewing texts describe the steam beer as generally an amber beer,
often compared to Munich beer. The color was due to caramel malt,
roast malt, caramelized sugar, or any combination of these.
Specific gravity was in the range of 1.044 to 1.050. The grist was
sometimes all malt but often contained corn. Sugars were frequently
added in the kettle, sometimes comprising as much as 33 percent of
the total fermentables. Many different mashing schedules and
methods were used, but it was very common for the final conversion
temperature to be near 176 F. The boil was generally from one to
two hours. About one pound per barrel of a bottom-fermenting yeast
was pitched. High kraeusen was usually established within 14 hours.
The beer was then run into the shallow wooden fermentation tuns or
“coolships”, to ferment for two to four more days at
temperatures generally in the low 60s. The shallow vessels helped
to reduce the temperature rise from fermentation and the production
of off-flavors in the beer. From there it was generally racked into
wooden barrels. Surviving steam-beer barrels are impressively
strong vessels, made with very thick staves and lined with pitch.
Some 30 to 40 percent of the volume racked into the kegs was fresh
beer at high kraeusen, depending on the desired degree of
carbonation. The unfermented sugars in this kraeusen beer would
condition the beer in the keg during five to ten days of aging at
the brewery. Finings would be added along with the kraeusen.
- Explanations of the word
"steam" are all speculative. The carbon dioxide pressure
produced by the kraeusening process was very high, some suggest on
the order of 40 to 70 pounds per square inch, and one possibility
is that it was necessary to let off “steam" before
attempting to dispense the beer, which would look and sound like
steam being released from a boiler. According to Anchor Brewing,
the name "steam" came from the fact that the brewery had
no way to effectively chill boiling wort using traditional means,
so they pumped the hot wort up to large, shallow, open-top bins on
the roof of the brewery. Thus during brewing, the brewery had a
cloud of steam around the roof let off by the wort as it cooled. It
is also possible that the name derives from "Dampfbier"
(literally "steam beer"), a traditional German ale that
was also fermented at unusually high temperatures and that may have
been known to nineteenth-century American brewers, especially those
of German descent.
-
- The modern “Steam Beer”
was originated by Anchor Brewing Company, which trademarked the
name Anchor Steam Beer in 1981. Although the modern company has
corporate continuity with a small brewery which was still making
traditional steam beer in the 1950s, Anchor Steam beer is a
craft-brewed lager. The company does not claim any close similarity
between it and turn-of-the-century steam beer.
- Those attempting to clone
today’s commercial variety may wish to include approximately
one to two percent of rye malt in the grist to add the touch of
sharpness that's so pleasing in the commercial example. Amber
colored wort similar to a bitter or an IPA is a good starting
point, and hop with Northern Brewer. All grain brewers will find
that if they have very soft water a little gypsum can be quite
helpful.
- Safety note: If you try to
kraeusen the beer at the historical rates noted above in a
Cornelius keg, make for darn sure that the safety pressure-release
valve is functioning correctly, and don’t even think about
trying it in bottles. They WILL explode.
