Homebrew accessory for oxygenation and rapid carbonation that helps improve batch consistency. Brewers gain confidence that fermentation and carbonation will be more reliable with less fuss. Is the Namvo Diffusion Stone the right upgrade for regular or ambitious occasional brewers?
⚡ At a Glance
- • Brewing Quality: Efficient oxygen transfer that supports stronger, more reliable primary fermentation
- • Best for: Homebrewers who use kegs or want faster, consistent carbonation
- • Not ideal for: Casual drinkers who do not carbonate or oxygenate at home
Design combines a 2-micron diffusion surface with stainless steel construction. Intended for use with an oxygen source or aeration pump and can attach to a keg gas-in for rapid carbonation.
Quicker carbonation - with a 2-micron diffusion surface
Microscopic pores force gas into thousands of tiny bubbles, increasing surface area contact with liquid and speeding gas dissolution. Using the 2-micron stone at the end of a gas line creates fine bubbles that transfer CO2 more efficiently than larger-orifice tubing.
Faster carbonation reduces conditioning time and helps achieve consistent fizz across bottles or kegs. Particularly useful when topping up kegs or speeding up bulk carbonation.
Better yeast oxygenation - thanks to aeration compatibility
Connection to an oxygen source or an aeration pump introduces oxygen through the diffusion surface, dispersing it evenly into wort. Even oxygen distribution helps yeast build healthier cell walls during prefermentation.
Healthier yeast populations lower the risk of poor attenuation and off-flavours. Ideal for batches where a strong initial fermentation is critical.
Built to last - with stainless steel corrosion resistance
High-quality stainless steel construction resists corrosion from wort, sanitiser and CO2 exposure, maintaining structural integrity over repeated use. Robust metal also tolerates pressure and handling better than ceramic or plastic alternatives.
Durable build reduces the need for frequent replacement and holds up to regular brewery chores. A practical choice for brewers who use an aeration stone often.

❓ Frequently Asked Questions
Q: What is the Namvo Diffusion Stone used for?
A: It is used for carbonating self-brewed beer and for oxygenating wort before fermentation, improving carbonation speed and yeast performance.
Q: What material and pore size does it have?
A: Made of high-quality stainless steel with a 2 micron diffusion surface for fine bubble production and corrosion resistance.
Q: How do I use it with a keg or oxygen source?
A: Use the stone with an oxygen source or aeration pump for prefermentation, or attach it to the end of a keg gas-in line with around 50cm of tubing to speed up carbonation.
🏆 Our Verdict
The Namvo Diffusion Stone suits homebrewers who want quicker, more consistent carbonation and better yeast oxygenation. Fine 2-micron bubbles and stainless steel construction make the stone effective for both prefermentation aeration and rapid keg carbonation. Durable materials and simple attachment options suggest sensible long-term value for frequent brewers.
