Stainless Wort Oxygenation Stones

Better Than Shaking a Keg!   Are you tired of carbonating your beer the unpredictable way? You crank up the PSI in the keg, shake, and wait with bated breath, hoping you didn’t just over-carbonate your batch. Using a diffusion stone pays off with a reliable level of carbonation every time.   Our .5 micron carb stone is ideal to force carbonate your kegged beer, or as an aeration stone prior to fermentation. It produces nice small bubbles, giving more surface area for diffusion.    0.5 micron stone 316 Stainless 1/2" diameter. Stone is 1" in length. Overall length is 1 7/8" The barb is 1/4" OD   To Use: Attach 2 feet of 1/4" tubing to the stone and the "gas in" dip tube inside the keg. (Tubing not included). Set your desired pressure on the regulator and gas gets emitted through the .5 micron stainless stone. The bubbles rise through the beer creating so much surface area contact between gas and liquid that the absorption rate is very rapid. This is very similar to how beer is carbonated in breweries.   Cleaning & Sanitizing: It is important to know the oils from your skin can clog the small pores in the stone. We that you attach the tubing to the stone, then hold the assembly by the tubing while submerging the stone in boiling water for a few minutes to break down and drive the oils out. When the stone comes out of the boiling water, tightly wrap it in saniitized aluminum foil until you are going to mount it in your keg.

Healthy yeast need plenty of oxygen to grow. Aerating your wort before pitching your yeast will give it just the boost it needs!    Use this 2 micron oxygen / carb stone with an oxygen source or aeration pump. The barb is 1/4" OD. (Note: if you are using an aeration pump, we recommend a "deep water" type for aquariums, to ensure teh pump is strong enough to force the air through the stone and into the wort)   Specifications AISI 316L Stainless Steel Stone is 1/2"" diameter and 1" in length. 1/4" OD barb 1 7/8" Overall length

New! Easier to Sanitize Design  This innovative design was the result of customer feedback about the difficulty of santizing our traditional barbed stone when tubing was attached. We added threads instead of a barb and now you can use the fittings you see at the bottom of this page to connect and disconnect your tubing. This allows you to place the stone by itself directly in a pot of boiling water to sanitize. Easy. 316 Stainless 1/2" diameter. Stone is 1" in length. Overall length is 1 7/8" To Sanitize To properly sanitize your stones, we recommend you run it in a sanitized solution for 5 minutes. If the stone becomes clogged we recommend boiling the carb stone for 1-3 minutes to help break down anything within it. Important Notes You do not want to touch the stainless stone portion with your hands. The oils on your fingers can actually clog the small pores in the stone. The stone does not come with the barb fitting or flare nut - those will have to be purchased on their own. See the Related Items below. The .5 Micron stone is more commonly used for carbonation. However it can be used pre-fermentation with an O2 tank and regulator for oxygenation. Not the ideal choice if you want to aerate with an oxygen pump (aquarium pump) - use KEG590 for aeration. And if you are looking for a neat, all-in-on complete system for carbonation check out our Carbonating Keg Lid.

The 2 Micron size is more commonly used for aeration or oxygenation pre fermentation, but can be used to carbonate beer. If you wish to use an aquarium style Aeration Pump to pump air through this stone we recommend a "deep water" type for aquariums, as these will have the necessary PSI to force the air through the stone and into the wort.
