Want to see the lag time between pitching the yeast and high krauesen significantly reduced? Try forcing pure oxygen into the fresh wort just before adding the yeast. Our new oxygenation assembly will make this an easy thing to do. The assembly includes an oxygen regulator which fits a standard disposable oxygen tank (available at most large hardware stores), an air filter, and a 2 micron stainless steel diffusion stone, plus all the tubing needed to hold it all together. Oxygen tank is not included because it is considered a hazardous material and is very expensive to ship.
