The brewery consists of many different pieces. The
brewhouse was manufactured by Wachsmann in Germany. It is capable of being
automated, but unfortunately the control console is in German and none of the
brewers speak German.
The 30 hectoliter (~26bbls.) brewhouse was built and assembled
in Germany and shipped over by boat. It was then slid carefully into
place, and has put out many thousands of barrels over the
Basically everything in the system is hard piped. All
the junctions and T's are underneath the platform. The push-button console
controls either pneumatic or magnetic valves. Pneumatic valves are
controlled by pushing or letting out air. Magnetic valves are controlled
with electro-magnets and solenoids. This is a picture of the heat
exchanger and the vapor condenser underneath the platform of the brewhouse.
The brewhouse has an electronic console that is used to
control all the valves. The picture on the left shows a full view.
The numbers on the right represent the heat exchanger temp., kettle temp, water
doser, wort run-off counter, and a flow meter. The picture on the right
shows the flow of the mash from the kettle to the lauter tun.
 
The (2) fermenters are from Pub
brewing. The fermenters are 60 hectoliters, requiring each batch of
beer to be 'double brewed' - two brews into one fermenter.
The lagering tanks are made by JV
North West. They are horizontal tanks, which fit snugly into the
parking garage height cellar, and allow for easier carbonation and clarification
due to the large amount of head space and bottom space. There are (6) 60
hectoliter lagering tanks.
There are (4) 60 hectoliter serving tanks by JVNW. This
poses a huge problem when there are 5 beers on tap, so the brewers have to keg
off an entire serving tank's worth of beer and stash the kegs throughout the
cold room.
They
also have a lab down in the cellar to perform testing like HLP and cell
counts. Not many breweries have labs, so it is a very nice thing to have.
Brewing
at GB is different from ale breweries because they do lagers. The
brewhouse is set up to actually mash into the kettle. This allows the
brewers to do step mashes and decoction mashes. The agitator in the kettle
keeps the mash mixing while it is heated through the enzyme ranges. The
cone in the middle supplies heat (steam) and helps create a good boil.
The
mash is then transferred over to the lauter tun and runoff is collected into the
whirlpool. Once a certain amount is collected, it is transferred back to
the kettle for boiling.
