The In-Line Oxygenation Kit designed by Blichmann Engineering- sets your brew day up for success. -The stainless steel diffusion stone dissolves oxygen into your wort to promote yeast health and vigorous fermentation. It also reduces lag times to produce the finest homebrewed beer without off-flavors from stressed yeast. -Unlike other products on the market, this product quickly and completely disassembles for cleaning and sanitation. -We have also selected a stone porosity that is the perfect balance between small bubble size for quickly dissolving the oxygen, yet has the permeability for sanitizers to fully and quickly penetrate the stone for proper sanitation. -Other manufacturers use stones so fine that sanitizers cannot penetrate them and they must be boiled to be properly sanitized. -But not ours! -Your success is our priority when it comes to brewing!
