Promiscous Yeast Molecules Is What Makes Wine So Delicious
Feb 28, 2012 12:13
Try to picture an orgy of super sex-crazed strains of yeast swirling about in that glass of wine you're about to swallow without feeling a bit weird about it.
According to EurekaAlert, researchers from Stanford University School of Medicine have discovered that many commercial yeast strains are super promiscuous, which makes their lineage difficult to trace, but is also the secret to why wine is so tasty. Gavin Sherlock, an associate professor of genetics and senior author of the research explains:
The strain of yeast used in fermentation definitely affects the flavor of the wine, and we thought that these strains would fall into a nice evolutionary-tree-like structure with a common ancestor.
But instead, the researchers found that
the yeast DNA was all mixed up from various strains and species. The researchers aren't sure whether the yeast's promiscuous behavior was encouraged by winemakers and bakers over time, or if it naturally occurred on its own.
They plan to investigate further and try to trace the genealogy of some of the strains in hopes of understanding how it affects wine production.
Our daily schedules can, very easily, become very hectic and busy at times. With each month seemingly going by faster and faster, it’s important to treat yourself every now and again. If you work full time, or you have a number of hobbies that keep you busy, it might be time to think about escaping for a break with your family and friends. Read more
We are living in a world where we are slowly becoming more aware of what we put in our bodies. As we are constantly bombarded with health warnings and advice on what we should and shouldn’t eat, we appear to making more conscious decisions when it comes to food. With so many people now opting to take part in exercise, as well as cutting down on the processed food, we are also becoming more aware of the quality of our food. Read more
Traveling often is not within everyone's reach. Some people have to live with constraints of time, health, family, money, etc. Fortunately, I do not have these constraints and I have the chance to travel regularly. For the past seven years, I have traveled 11 times to discover a total of about 20 countries. The length of my travels vary enormously, from several months for some to just a week for others.
