  • Best Carb stone for 100 bbl bright?

    We are setting up a 100 bbl bright that we bought used without a carb stone. It has a 3" port. I was considering buying two of the 8" stones and fabricating them onto a 3" cap to form a dual stone. Any other suggestions? Or sources for large stones?

    Thanks for any input.

    Zahm & Nagel can set you up with a stone designed for your bright tank. You're using a 100bbl bright, so use a professional solution.

    Avoid the ceramic stones--they're very fragile. Z&N recommends then for larger vessels, but we found the SS stones to perform well and endure much longer.

      I agree with TGTimm. We have both and the stainless version is SO much better from Zahm.

        We have custom Zahm setups in our 90bbl tanks. They are 18" I believe, on a long shaft to place the tip of the stone just short of the center of the tank. We carb inline, so they are just used for fine tuning though.

          In line carbonation

          Thanks for the replies. I will call Zahm.

          When you say carb inline is it only during the transfer from fermenter? Seems like that would only take a couple of hours at most.

          My fermenters don't get cold enough for that so I must wait until the bright temp is low enough.

          Thanks again for your input.

            We were having issues with our beer warming up when transferring to the brite. We installed a small heat exchanger from Alfa Laval and run the beer through it on the way to the brite and we're able to get the beer cold enough to carb over night and be ready to package the next morning. Could help solve the issue of your fermenters not getting cold enough.

              A few other things...

              Use at least two stones, within the same quadrant of the tank, but not next to each other. They should be placed horizontal and low in the tank. They should also be at least 12 inches long--depending on how quickly you wish to carbonate--and independently controlled for flow. Putting them on a long shank so that they get closer to the center will help with natural convection of tank cooling and carbonating evenly. Put a check valve on each one--even if the stones come with Thomas valves. It's a mess to clean CO2 lines if they get contaminated with beer. Be sure to calibrate your temperature and pressure measuring equipment and you should be good to go with perfect carbonation first time out of the box. Good luck!
