A member of our homebrew club organized a great tour of the Anheuser Busch Farfield Brewery yesterday. Since he works at the brewery, we received a great 2 hour behind the scenes tour.
The Farfield brewery has a 4 million! BBL production capacity and is actually one of the smaller A-B breweries. The LA Brewery can produces 12 milling BBL a year and the St. Louis Brewery can produce about 16 million BBL a year. Which is a truly amazing feat.
I wish I had taken more photos but I spent most of the time in awe of how the brewery operated.
One of the first places we stopped was the finishing fermentors.
There are 140 of these 1,600 BBL fermentors which span three floors of the building.
Beer is finished on birch wood in these fermentors. The birch wood is stored in these torpedo shaped canisters.
There brewery is incredibly energy efficient both in reclaiming water and also energy. All not brew water is used in atleast two processes. For example, the water from the last clean in place (CIP) cycle on a tank is saved and used as the first cycle on the next tank to clean. The brewery also has a bio-digester to generate methane to power the brewery, a giant windmill, and is planning on installing solar panels.
The brewery was automated in 2004 and now only needs 5 people per brew shift to operate everything. All brewing and tank transfers are controlled from a center control room in the brewhouse.
