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.
