Brewing: From Grains to Glass
The
Brewing Process:
The Ingredients: At Solstice Brewing Company we begin each beer by selecting the
proper malts to achieve the color, body, and roasted or carmel flavors in the
finished beer. Light beers have little or no roasted or toasted malts and dark
beers have a lot of heavily roasted malts.
The malt is then “cracked” in a
mill and mixed with hot water in the mashtun until the temperature is stabilized
somewhere between 148 and 158 degrees. The grains are then steeped for
approximately 60-90minutes. During this time natural enzymes in the grain spring
to life and begin breaking down starches in the grain into fermentable sugars.
After the grain has been steeped
it is then sparged (rinsed) with warm water. The sparge water runs over the
grains, picking up the sweet liquid along the way, and moves into a boiling
kettle. After the grains have been sparged with the appropriate amount of water
the resulting liquid in the kettle is called wort.
The wort is then brought to a
boil and hops are added. Hops are boiled in the wort for different amounts of
time to bring out different flavor profiles. The addition of hops at different
times of the boil can change the amount of bitterness, the aroma, and the herbal
flavor of the beer.
Once the hop boil is complete the
wort is cooled and yeast is added to begin the fermentation. The yeast begins to
consume the fermentable sugars in the wort and produces alcohol and Co2 as
by-products. After 10-14 days the yeast will have consumed all of the sugar and
go dormant. The beer is then cooled for several days and then filtered.
Calculated amounts of Co2 are then injected into the beer to give it just the
right amount of bubbles. The beer is then ready to be packaged for shipping or
served up straight out of the tanks of your local brewpub. Cheers!
