Saccharomyces cerevisae: Beer Brewing

Saccharomyces cerevisae: Beer Brewing

Purpose
The purpose of this lab was to demonstrate the role of  Saccharomyces cerevisiae in the process of beer brewing.


Materials and Methods
A protocol from Austin  HomeBrew Supply was used to make  AHS American Amber ale.
Liqiud malt was used as the major starting ingredient. It is important to mantain a sterile environment during the whole process.

                                            Adding some sugar before beer botling

                                         Carbonating the beer keg

                                        Finally bottled beer!!

Conclusion
From the looks of things we managed to make un contaminated beer and preliminary organoleptic tests seem to indicate that we got the expected test and alcohol content.
