Aeration and oxygenation systems provide a way for you to quickly and effectively infuse a boost of oxygen into your wort to ensure a healthy environment for the yeast to ferment in. You can choose from an aeration system that uses a pump to move air through a diffusion stone and into the wort, or an oxygenation system that pushes pure oxygen from a tank, through a diffusion stone into the wort. Both ways give superior results over simply shaking up your beer.
