The Hopper and the Mash/Brew Kettle
The HOPPER and the MASH/BREW KETTLE

We use different brewing techniques for each of our beers. The technique (either a form of decoction or rising temperature infusion depending on the style of beer), is chosen to extract the desired elements from the malt.

Barley
BARLEY
The brewing process starts out by milling the malt, then mixing the specially-cracked malt with water to make a malt porridge. The mixture is heated through the desired temperature ranges and then moved from the mash kettle to the lauter kettle.

Hops HOPS The Lauter Kettle Lautering is a process which separates the spent malt from the liquid, called wort. After the wort is clarified, it is moved to the brew kettle and cooked to enhance its flavor and to sterilize it. During the process hops are added to balance the malt sweetness with the bitterness of the hops.

The Heat Exchanger After cooking, the wort is spun in a whirlpool to remove spent hops and excess protein. Then the wort is passed through a heat exchanger to cool it to the correct fermenting temperature. The level of cooling is dictated by the type of yeast used. The starting temperatures are around 17 degrees Celsius for ales and around 9 degrees Celsius for lagers.


The HEAT EXCHANGER

The cooled wort is sent on to a fermenter, where a special strain of yeast is added, again depending on the type of beer. Whether the beer is an ale or a lager a vigorous fermentation marks the beginning of the fermentation cycle. Once the beer is fermented out (a point where almost all of the fermentable sugars are changed to CO2 and alcohol), the temperature of the new beer is chilled to near freezing to get the yeast to drop out of suspension.

The FERMENTATION TANKS

When the aging and settling process is complete, the beer is double-filtered to remove the remaining yeast. In our restaurant, our beers are drawn directly from special brewery tanks and served under ideal conditions at the peak of their flavor.
