Description
Oxygenation stone 2.0 micron – aerating wort with an air pump
Stainless steel oxygenation stone with 2.0 micron pores. The stone spreads the air in small bubbles so the wort takes up oxygen before the yeast is pitched. It is recommended for use with an aquarium pump. The barb has a 1/4" outside diameter and fits tubing with a 3/8" outside diameter (LLDPE).

Cleaning the oxygenation stone
- Rinse the stone thoroughly in hot water straight after use to remove wort and yeast residue.
- Wash it in a suitable brewery cleaner, for example PBW or another oxygen-based cleaner. Mix according to the manufacturer's instructions, soak the stone for 20–30 minutes and rinse thoroughly in hot water.
- Before use, sanitise the stone by placing it in a solution of Star San or another suitable sanitizer for at least 5 minutes.
- Let the stone dry completely and store it clean and dry until the next brew.
- If the stone is badly clogged, boil it in water for 10–15 minutes or soak it in a mild phosphoric acid solution.
- Do not touch the surface with your fingers. Grease from the skin can clog the fine pores.
Frequently asked questions about oxygenation stones
Why should wort be oxygenated?
Yeast needs oxygen to multiply. Too little oxygen can cause sluggish fermentation, poor attenuation and off-flavours. It matters most for high-gravity beers, lagers and large batches.
What is the difference between 2.0 and 0.5 micron?
The 2.0 micron stone is recommended with an aquarium pump, which blows ordinary air. If you use pure oxygen from a cylinder, we recommend a 0.5 micron stone.
When should I add oxygen?
Only before the yeast is pitched. Never add oxygen after fermentation has started.
