Iowa's Most Historic & Award-Winning Micro Brewery
OVERVIEW OF THE MILLSTREAM PROCESS
The Millstream brewing process is simple and traditional. We grind our fine barley malt through the mill into the "mash tun", where the malt is steeped with water at critical temperatures to produce the sweet liquid called "wort". The wort is then boiled in the brew kettle along with our select hops which impart the bouquet and touch of bitterness essential for proper balance.
Following brewing, the hot wort is cooled and yeast added. The liquid is transferred to a chill tank in our cellars where natural fermentation takes place.
Now the brew master patiently waits until just the right moment when fermentation is complete. Then the new beer is transferred into the lagering cellar where it ages for several weeks.
Next the beer is filtered and carbonated to get it ready to be packaged in the bottling line. Frequent taste testing and lab analysis is necessary to ensure a quality product. The best test though, is to see people relaxing and enjoy a brew in our hop-covered Beir Garten. Prost!
