Happy Yeast means better beer!
From Anvil Brewing Equipment comes an Oxygenation kit! Includes a 10 micron stainless diffusion stone, heavy duty 24" dip tube to reach the bottom of your fermenter, tubing and a 1/4" nut and stem.
The 10 micron stone is stainless steel and is perfect size for oxygenation, yet pourous enough to let sanitizer pass for easy sanitization.
