xEnhance your homebrew with Ferroday 0.5 Micron Diffusion Stone
Crafted from 304 stainless steel, this diffusion stone is built to resist corrosion and high temperatures while delivering steady, reliable performance. The 20 inch gas line is made from food grade silicone, providing flexible routing and a secure seal for a variety of setups.
Why finer bubbles matter
With a 0.5 micron aperture, the device produces smaller, more uniform bubbles that interact with liquids more efficiently. This can help create a smoother head on draft beer, enhance oxygenation during wort preparation, and brighten carbonation in sodas and flavored beverages. Real-world results depend on your process and ingredients.
- Small, consistent bubbles improve gas transfer for faster carbonation and oxygenation
- Durable stainless steel construction stands up to cleaning cycles and heat
Versatile tool for your homebrew and beverages
Use the diffusion stone to oxygenate wort before fermentation or carbonate beverages after fermentation. The 1/4 inch ID hose barb makes it easy to connect to a keg post or regulator, supporting a smooth workflow in many setups.
- Ideal for pre-fermentation wort oxygenation
- Suitable for carbonating draft beer, soda, or specialty drinks
Care and maintenance for ongoing performance
To preserve pore openness and flow, boil the diffusion stone before first use and after cleaning. If the pores clog, a brief acid dip (about 15 seconds) followed by a rinse can restore performance without disassembly.
- Boil before first use to sanitize and unclog pores
- If blocked, dip in mild acid for 15 seconds and rinse
- Rinse thoroughly after cleaning and store dry
