Item currently out of stock

This 26in stainless steel wand is outfitted with a 2 micron sintered stainless diffusion stone on the end of it. Perfect for oxygenating your must during fermentation and for degassing wine with nitrogen. Use with 3/8" ID tubing - D1704.

You can learn more about the use of oxygen during fermentation by reading our Guide to Macro Oxygenation and Fermentation

Sanitizing your Diffusion Stone:

To properly prepare your stone for use, we recommend you boil the stone portion in water for 1-3 minutes. By heating the stone to boiling temperatures you kill all possible contaminants that may be hidden within the stones micro pores. Using a surface sanitizer is not a guarantee from contamination. Boiling also greatly reduces clogging issues by helping to remove sugar residue.

If boiling is not an option, for whatever reason, we recommend the next best, soaking in Star San. Star San will remove a majority of surface contamination/bacteria, but will not sanitize the interior of the stone which may or may not be contaminated.

Please note that 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.

Overall Length 26 7/8"
OD of wand 3/8"

Good Choice!
I use the diffusion stones with the flimsy tubing but after purchasing and using it this makes the process much easier.

Replacement diffusion stone
I have been using a diffusion stone for probably 10 years and the other day, when I started a batch, my old diffusion stone came apart. I was devastated. I got this uneasy feeling that after all of the hard work of preparing the brew that it couldn't possibly create a decent beer. I immediately ordered a new stone to restore sanity to my fermenting process. I have always had very active fermentations and have attributed much of that to the use of the diffusion stone for 30 seconds of pure oxygen into the finished wort. I don't think that I will ever be without some sort of diffusion stone to aerate my wort for active fermentation with healthy yeast. Thanks MoreBeer for having the products that make us all feel more comfortable brewing.

One of my best investments.
Since purchasing this and using with pure O2, my beers have improved dramatically. I always have quick starts and lower finishing gravities than I had before. Huge improvement over shacking the carboy.
