Our beer begins life as plump grains of premium two-row
barley. In the malting process, the grains are soaked in water and
allowed to germinate. Kilning or roasting the malted grains develops
distinctive character and gives the beer its rich flavor, color, and
body. We use only premium barley malts, and never corn or rice fillers.
Each year, we hand-select the finest hop cones from
growers around the world. To achieve the complex hop character that
is our trademark, we add different varieties of whole hops to the
brew kettles at specific points during the boil. Bittering hops go
into the brew kettles early to balance and offset the sweetness of
the malt. The most aromatic hops are added near the end of the boil
to capture the volatile oils that infuse our beers with their intense
flavor and aroma. Our Bigfoot Ale, Celebration Ale, and other specialty
beers receive an additional “dry-hopping” during the maturation
period.
Yeast is the magical organism that works its alchemy
on the malt and hops to produce our flavorful brews. We maintain and
culture several different strains in our laboratory to produce our
classic ales and lagers. Our ales are produced utilizing our original
distinctive strain of top-fermenting yeast. This special yeast, and
our carefully monitored fermentation profile, helps to produce the
wonderful aromatic qualities found in all of our ales. We seasonally
propagate a classic cold-fermenting lager strain to produce our range
of traditional all-malt lager beers. We will often culture unique
yeast strains from around the world to produce small batches of distinctive
beers.
Chico's location at the base of the Sierra Nevada and
Cascade mountain ranges affords us a pure and plentiful source of
water. Our brewing water is pumped from a deep aquifer that is continually
recharged by the snow and rain falling in the nearby foothills and
higher peaks. Like all of our brewing ingredients, we carefully treat
and monitor this vital raw material. Because of our commitment to
the environment and our local community, we strive to use this valuable
resource efficiently. Wastewater generated by the brewery is thoroughly
treated in our state-of-the-art recycling plant before being discharged.
So what distinguishes an ale from a lager? It has
nothing to do with strength, color, or bitterness. It’s the
yeast and the fermentation temperature. Ale yeasts ferment best
at warmer temperatures—as high as 75° F. Because yeasty
foam rises to the surface of the beer, these are known as “top-fermenting”
yeasts.
Lager yeasts, on the other hand, prefer cooler temperatures.
They are called “bottom-fermenting” yeasts because they
sink to the bottom of the tank at the completion of fermentation and
during the cold-storage period traditional for lager beers. This process
removes haze and gives lagers their characteristic clean, rounded
tastes.
