Healthy, happy yeast is essential to avoiding off-flavours in finished beer, and making sure your wort has enough dissolved oxygen for yeast to grow is a sure-fire step towards clean, consistent and quality beer.
There's an old saying in brewing: "Brewers make wort; yeast makes beer". Given the time and attention we brewers lavish on creating the best wort possible, doesn't it make sense to help yeast to do the best job it can too?
Maximising the the level of dissolved oxygen in your wort decreases lag time, greatly improves yeast attenuation, and avoids yeast stress and subsequent off-flavours by ensuring there are sufficient cells to get the job done. It is particularly important for lagers and higher-gravity beers.
