THE GRAIN ROOM |
|
Here
is where we begin our brewing process. Almost any grain can be used
in the production of beer, but we choose to use Barley, the preferred
grain. Our maltsters supply us with the finest imported "2-row"
English malted barley. To this we add other specialty grains from
around the world in order to produce our unique beers. The malted
barley comes to us in 55 lb. grain sacks, and are hand loaded into
our mill. Unlike many other breweries that purchase their grain
by the tanker and then pump it into silos, we prefer these small
grain sacks. By using these we are able to inspect, smell and taste
all the grain as we begin the brewing process. In this process the
grain is loaded into the grist mill (the red machine) and cracked
open to expose the starches inside the grain. These starches will
give the beer flavor, color, body and some will be fermented into
alcohol. As the grain is mill it is augured into a holding vessel
called the grist hopper. |

MASH TUN |
|
The
milled barley is now placed into the Mash Tun. Here, hot water is
mixed with the grain starting an enzyme conversion process. This
converts the starch to two different sugars- fermentable and non-fermentable.
The mash tun has a slotted screen false bottom. This allows us capture
the sweet liquid called "wort" and leave the grain husks
behind. These husks or "spent grain" still have nutritional
value and is given to our local organic farmer. As we capture the
wort, hot water is sprayed "sparging" on the top of the
grain insuring extraction of most all the sugars. Form here the
wort is pumped to the brew kettle. |
 |
BREW KETTLE |
|
Here
the wort is vigorously boiled for one and a half hours. Three major
things happen in brew kettle. First the heat sterilizes the wort.
Second, evaporation reduces the volume and makes the flavors much
more intense. Lastly here is where we add the hops to the beer.
Hops give the beer the bitterness needed to balance the sweetness
from the grain. Once boiling stops we circulate the wort in a swirling
motion, called "whirlpool". By mechanical action any particulates
are driven to center, just like when you swirl tea leaves in your
cup. Once settled, from the side of the tank we draw off the clear
wort. Before leaving the brewhouse the wort must be cooled to about
65 F. This is done by pumping the hot wort through a heat exchanger.
Then its off to the fermenters. |
 |
FERMENTATION |
|
As
the cold wort is pumped to the fermenters yeast is added. This single
cell animal metabolizes the fermentable sugars in the wort producing
alcohol and carbon dioxide. Fermentation generates a lot of heat
so to maintain a constant temperature our tanks are "Jacketed"
with a cooling system. Depending on the style of beer being made
fermentation can take from ten days to six weeks. As the fermentation
process comes to an end we chill the beer causing the yeast to fall
to the bottom of the tank and leave the beer bright and clear. |
 |
RACKING AND PACKAGING |
|
Upon
completion of fermentation, some of our beers are filtered, then
held in conditioning tanks. Here extra carbon dioxide may be added
"polishing" to replace what was lost in filtering. Now
the beer is ready to be packaged. The beer is then kegged or caned
and is now ready for all to enjoy!! |
