The Family Tree of Beer: A Team of Geneticists is creating the Beer Yeast Genome Project
In a lab in San Diego, Troels Prahl, a brewer and microbiologist at the Southern California yeast distributor White Labs sits at the tasting bar in front of 4 open half pints of beer. Each of them is different, in color and flavor, ranging from a crisp body of raspberry, rosemary and banana to a dry and subtle blend of nutmeg and fresh straw. But with the single exception of the yeast they were brewed from, all the beers are identical.
