Yeast gene expression

I am scheduled to give a hour long presentation for my fungi class and with my passion of brewing beer I decided to give it on different genes within the Saccharomyces that give beer different characteristics. Anyone have info on a good place to look for this information or can give me information on what they know? It is greatly appreciated. Thanks!!!
