Introduction
Offshore
Ale's goal is to make beer from scatch that distinguishes itself
clearly from the mass-market brews we are all too familiar with.
Instead of outlandish marketing campaigns, we choose to spend our
resources and energies on making a range of beers full of aroma and
flavor. We brew crisp, golden lagers, copper colored Pale Ales, highly
aromatic IPAs, an award winning Nutbrown Ale, unique Belgian Style
offerings, and coal black stouts. With 10 beer lines and two cask
engines we can offer a lot of variety. Our Head Brewer, Neil Atkins, is
known for making several different seasonal and special brews, along
with regular beers of distinction.
To
get the full range of color, flavor and aroma of the types of beer we
make, it is important to understand the basic ingredients. Each brew is
a blend of four items: malt, water, hops, and yeast. Varieties and
quantities of each item will change the character of the beer. It is up
to Joe, to ensure that the water for brewing is pure, that the yeast
strain is healthy, and finally, to balance the malt body with the hop
bite, with the freshest possible ingredients.
Malt
Malt-- "The Soul of Our Brews"
Malt
is typically barley, a cereal grain, that has been soaked in water,
germinated, and then kilned. During the malting process, naturally
occuring enzymes in the barley begin to convert starches to sugars that
will later feed the yeast used in fermentation. The amount of heat and
water sprayed on the grain during the malting process also produces
varying degrees of distinctions, with further roasting giving the
deepest colors and flavors. The blend of these various types of malt
give beers their fermentable and non-fermentable sugars as well as
color and body.
-
Malt provides the color to the beer. Pale and Pilsener malts give us
golden ales and lagers. We use Pilsener malt in our East Chop
Lighthouse Lager. The Stonewall India Pale Ale has pale malt, and
crystal (caramel) malt for its copper color. We use Pale, crystal and
chocolate , a dark roasted malt, to give the Nutbrown Ale its
distinctive deep brown appearance. Porters and Stouts have about 10%
Roasted Barley or Black Patent Malt for their deep, black color.
-
We
also brew with specialty malt for certain beers. We blend in Pale Malt,
Munich and Vienna malts for our Munich Helles. We also use various
malts like Smoked Malt, Wheat Malt, Flaked Oats, and Rye Malt depending
upon the brew.
-
The
amount of alcohol in the final product is directly related to the
amount of malt in the brew. Malt contains sugars that the yeast
converts to alcohol during fermentation. The unfermentable sugars from
malt, dextrins, create the body of beer. Whereas the fermentable sugars
are converted into alcohol.
Our beers range in strength from 4% abv. [East Chop & Nutbrown] to 10% abv. [Imperial Stout].
Hops
"The Spice of Beer"
If
malt is the soul of beer, then hops are the spice. Hops provide
bitterness and aroma to beer. Hops grow on vines, producing tiny
flowers that look like soft green pine cones. They are resinous and
sticky. Once they are harvested and dried, they are vaccuum packed as
whole hops or hop pellets. We use a number of different varieties of
hops that are traditional with either ales or lagers.
-
Cascades, Amarillo and East Kent Goldings varieties are used in the ales we produce for their floral and fruity aroma.
-
Hersbrucker Halletau,Czech Saaz, and Tettnang hops are used in German lagers for their spicy aroma and noble character.
-
Other hops we like to have fun with are...Crystal,Chinook, English Fuggle, Perle, Slovian Goldings, Sterling and Ahtanum
Hops
are added to the kettle during the boil. The longer they are boiled the
more bitterness is extracted. For flavor and aroma, we add the hops at
the very end of the boil and into the whilrpool.
We
add whole hops to the cellar tanks for the IPA and the other special
ales to provide a more intense hop aroma. This process is called dry
hopping. No bitterness is added when dry-hopping.
Water
Water makes up 92 - 95% of each glass of beer.
Our water on the Island of Martha's Vineyard is an excellent source for brewing.
Yeast
Yeast
is a single celled microorganism that ferments various sugars in the
wort in the presence of oxygen. The two main by-products of
fermentation are carbon dioxide and alcohol. Keeping the strain pure
and clean is the most important part of the process to ensure a
repeatable fermentation and consistent final product.
- Offshore Ale Company has two main yeast strains, a lager, or bottom fermenting strain, and an ale, or top fermenting strain.
- Both
yeast strains are kept on slants in a laboratory at White Labs for our
use. When we need a fresh batch of yeast, usually every 2 - 3 months,
they provide a fresh, new starter culture.
- Ale yeast produces a distinctive fruity flavor to the beer
- Lager yeast produces a distinctive, slightly dry , more neutral flavor to the beer.
White
Labs also has an extensive laboratory of specialty strains of yeast our
brewer finds interesting to brew with. Belgian yeasts from Trappist
Monks and traditional German Hefeweizen yeasts are used for special
limited release beers.
Brewing Process
Mash
Milled Malted Barley (or Rye, Wheat, sometimes even Rice and Corn) are
added to the grist bin, which is situated above the MASH TUN. It is
then dropped slowly into the Mash Tun where it is mixed with hot water,
creating a mash. The Mash rests for at least 1 Hour so that all
starches in the malt can convert to sugar. This sweet, fermentable
liquid from the mash is called wort. The wort is recirclated in order
to create a clean,clear wort. This is to vorlauf or turbwort. This
sweet wort is then run off through the screened plates in the Mash Tun
to the KETTLE where it will be boiled. While the wort is running off,
we spray the grain with more hot water, a process called sparging. Once
all the wort is completely run off, the spent grains are picked up by a
local farmer, Elisha Smith for cattle feed. He also usually brings us
fresh eggs and sits down at the bar to enjoy a half pint of Pils.
When the kettle is full, we start the boil, and add hops to the wort.
We use a number of different aromatic hop varieties for our beers.
After 1.5 hours of boiling, we cool the wort to fermentation
temperature through a heat exchanger into one of our 10 bbl fermenters.
Ferment
While cooling into the fermenter, yeast is added through the manway,
and the tank is then sealed up. Our ales are made with a top fermenting
yeast strain that actually floats to the top of the wort as krausen,
and our lagers are made with a bottom fermenting strain that settles
during fermentation. Ales ferment at around 69° F for 4 – 7 days.
Lagers ferment at a lower temperature of about 48° F for 10 – 21 days.
At the end of the fermentation, the temperature is lowered to allow the
yeast to settle out and be harvested to be pitched into the next batch
of wort. Beer flavors mature at this stage, called secondary
fermentation, during the 7 - 14 days of storage. We also "dry hop" some
ales at this stage, adding hops to the cellar tank to give beer more
aroma.
FOR CERTAIN LUCKY BEERS...we have
Wooden Casks. Some are from Bourbon Distillaries, others are from
Wineries. We age our Inkwell Imperial Stout and Kilt Lifter Scotch Ale
in these casks. This aging process adds flavor rarely found in beer.
Just try one and you'll be hooked.
Filtration and Serving
After aging at about 40° - 50°, the beer is cooled to 33° F in the
fermenter. Under pressure, the beer is transferred through cellulose
sheets in our FILTER PRESS and into a SERVING TANK. Once the beer is
filtered it is then carbonated in the serving tank. It is now ready to
be poured by one of our friendly bartenders, Glen, Shae, Sam, Brooke or
John. Our beers are all natural and without preservatives, fresh,
unpasteurized and delicious.
Note: Not all of our fresh brews are filtered. It is normal and
expected to find a little cloudy appearance in some of our beers such
as, the IPAs and Hefe-Weizens and any of our Vintage and Wood Aged
beers. Enjoy them naturally!!!
