Iowa Beer, German Tradition |
Boil |
To brew literally means to boil as such it is a critical part of the process. Boiling plays a number of roles in the production of beer, from sterilizing the wort (unfermented beer) to darkening the color to removing unwanted proteins. Our system actually boils under pressure (hotter then 100 degrees) to more effectively remove undesirable materials for a cleaner beer. |
Perhaps the most important feature of the boiling stage is that this is when we add hops, a key ingredient in beer. Hops can be thought of as the spice of beer. They are plant flowers that are very bitter and aromatic. The yeast are never able to use all the sugar during fermentation so the hop bitterness is used to balance the residual sweetness. Depending on when you add the hops you can accent different features. The bitterness comes out with the boil; however the aroma is boiled away. So if you add hops early you get bitterness, if you add them late you get aroma. On top of this there are dozens of varieties of hops so the possibility for different beers is endless. We use only German Noble hops in Einfach beer. These are the highest quality hops from the finest regions in Germany. They provide an extremely clean bittering balance to our beer. |
