Bringing the Glacier Fresh taste to life

Mash Mixer
Mash mixer is where the brewing process begins and the ground malted barley and water are mixed.
Natural enzymes in the malt break down starches into sugars, which are used by the yeast to produce alcohol during fermentation.
This mash mixes for approximately 2 hours where it is then pumped to the lauter tun.
Lauter Tun
The Lauter Tun filters mash into two components:
      Mash (remains)
      Wort
Filtration process takes up to two hours as the wort is moved through the bottom of lauter tun onto the Brew Kettle
Brew Kettle
The wort boils in the Brew Kettle at temperatures of 100° C or 212° F.
At this point:
      Color develops
      Wort is sterilized
      Excess water boils off
      Hops are added
The Brewery uses specially selected hops which are added at certain intervals and add aroma as well as a slightly bittering taste
Hot Wort Tank
Hot wort leaves the brew kettle and travels to the Hot Wort Tank
Wort sits here briefly, giving time for leftover hops or protein to settle before being pumped to Wort Cooler
Wort Cooler
The wort cooler acts as a heat exchange
It is made up of vertical chilled water plates and when the wort enters it's a temperature of 98° C, and leaves at a much cooler 13.5°
Fermenter
The fermenter holds the wort while the yeast is added
Yeast ferments the sugar in the wort into alcohol, which is the step which creates beer
This process takes anywhere from six to ten days depending on the type of beer
Centrifuge
The next step is the aging process
As the beer is transferred to the aging tanks, the centrifuge separates the yeast from the fermented beer
The removed yeast is stored in refrigerated tanks which is reusable ten to twelve times
Aging Tanks
The beer is then chilled in the Aging Tanks
It remains here anywhere from one to three weeks depending on the type of beer
There are 25 aging tanks in the brewery.
Beer Filter
The Beer Filter removes any yeast that's left, this is the stage that gives the beer a bright and clear appearance
The filter itself is made up of vertical stainless steel mesh screens coated with celite
The filtered beer is then carbonated by adding CO2 as it is transferred to the bottling or kegging tanks
The alcohol content is then checked to ensure it is within the correct parameters
Beer Tank
The finished beer is then held in a Bright Beer Tank
This is where quality tests are performed
When the beer meets all the quality requirements it is cleared to enter the bottleshop
The filler will draw the beer from the tanks via pumps and lines where it will then be bottled
The Bottleshop
The bottleshop is where the beer is bottled before and packaged before being distributed
The entire bottling process takes approximately 2hrs 40minutes
Depalletizer
The depal removes returned cases from pallets stacked seven tiers high
It then sweeps each tier off one at a time onto the de-scrambling table
The operator then directs the cases onto the conveyor that takes them to the bottom saw
Uncasing/Saw
The bottom saw cuts off the bottom of the cases as they pass by
The saw operator removes the case remains as they pass by
The bottles are then picked up by the debris remover and discharged onto the bottlewasher’s supply conveyor
Bottlewasher
The bottlewasher acts similar to a giant dishwasher
It removes labels and thoroughly cleans the bottles both inside and out with a hot caustic solution
It takes bottles 28 minutes to pass through the washer
Bottle Filler
The bottle filler controls the entire functionality of the bottleshop
This is where the beer is bottled
The filler operator:
      Ensures bottles are filled to proper levels
      Correct crown torque and crimp values are applied
      Ensures correct C02 levels in the beer (alcohol- content)
Pasteurizer
Pasteurization is the process of heating that protects the flavor and consistency of the beer
It destroys any stray yeast cells leftover in the beer
Bottles are slowly raised to a temperature of 61°C then cooled back down to room temperature
This process takes approximately 40 minutes
Labeler
In the labeler, the label is picked up and applied to the bottle with a fast-drying glue
The label is then smoothed over the bottle
Case Packer
The Brewery cases its beer in 6, 12, 15, 18, and 24 packs
The cases are unfolded, the beer dropped or slid into the case and then folded and glued in place
A similar fast drying glue is used to seal the cases
Each case is coded to identify its production date which is so precise it is coded down to the very minute it is cased
Palletizer
The palletizer stacks the cases on a pallet and spin wraps them in stretch wrap for protection and security
The process is now complete and the beer is ready for distribution
