Only the finest ingredients go into the production of Grimm Brothers Beer. We use four basic ingredients: malt, hops, water, and yeast.
Brewing a beer starts by combining milled malt with warm water. This mixture is then held at temperature, which allows the enzymes in the malt to break down the starches in the grain into sugars.
This process all takes place within the “mash tun”
The next step in making a beer is called Lautering. During this step, the mash is brought to a temperature of 170°F which stop the enzymatic conversion of the starches.
The wort is then drained from the bottom of the grain bed and fresh warm water is added to the top. This addition of water allows the sugars to be rinsed and separated from the grain in a process known as “sparging”.
Once all sugars have been removed from the mash, the wort is brought to a boil. During this time, hops are added in order to give the beer additional flavor, bitterness, and aroma.
Once the boil is complete, the liquid is cooled and transfered into a fermentation tank where yeast is added. The wort will set at this stage for several days while the yeast produces alcohol and carbon dioxide.
Once all of the sugars have been converted to alcohol, the beer is dropped to a near freezing temperature to allow the beer to condition and lager.
This step allows the beer to mellow and clarify. Depending on the type of beer being made, this process can take anywhere from 2 to 4 weeks.
The beer is then carbonated and packaged into kegs and bottles for consumption.
