The Brewers Almanac reports that during 2008, twenty traditional brewers and 1,659 specialty
brewers produced a total output in the United States of 180.4 million barrels of beer (a barrel
contains 31 US gallons).
During the same year, the United States imported 25.9 million barrels
of beer produced in other countries.
consumption of beer in the United
States has risen from 16.0 gallons per year in 1900 to 19.8 gallons in 2009.
The total value of
shipments by the US brewing industry during 2007 was approximately $21.2 billion.
Slingsby Brewery is a regional US brewery that specializes in high quality, English-style ales. Its
product lines include brown ale, pale ale, porter and stout.
Slingsby makes its beer using a
traditional process of blending sugars from malted barley and wheat grains, hop flowers and
water. The skill of the brewmaster creates the desired aroma, color, foam and flavors through
recipes, fermentation and aging.
The brewing process consists of malting, milling, mashing, brewing, cooling, fermentation,
racking and finishing.
Malting is the process of getting the barley ready for brewing. Malting allows wetted
grain to germinate, releasing starches.
The brewer then dries the malt in a kiln and
sometimes roasts the dried malt.
Milling crushes the grain into grist to increase its surface area;
Mashing mixes the grist with heated water in a vat (called a mash tun) to convert the
starches to sugars for fermentation. The brewer then strains the sugar rich water in a
process of lautering to separate the liquid, known as wort, from the grain solids.
Brewing boils the wort in a brew kettle. The boiling stage of brewing involves many
technical and chemical reactions.
During this stage, the brewer makes important
decisions that will affect the flavor, color and aroma of the beer.
The brewer adds certain
types of hops at different times during the boil for either bitterness or aroma.
The brewer passes the wort through a device that removes the solids, and then transfers
