I'm a new brewer and need to find out how to add finings to a closed conditioning tank. Due to the setup of our systems we are using conical fermenters for both fermenting and conditioning. How do I get the finings into the tank which is under pressure without hurting the beer? thanks!

Adding Finings
If you're transferring the beer from unitank to conditioning tank I would suggest you mix your finings in a small vessel such as a keg, or cornelius keg and add them during your beer transfer. You can use CO2 pressure to push the finings out of the keg and dose them into the beer stream while transferring. You just need some misc. fittings like a Tee, butterfly valves, small jumper hose from the keg and a sight glass. I wouldn't recommend adding the finings up through the sprayball as you won't get much fining action accomplished. Of course make sure all components of the transfer system are clean and sanitized.Mike Jordan

Adding the finings through the zwickle may be your best bet while gently rousting with CO2. If you've purged all the yeast off the bottom of the FV you could also recirculate the beer from the bottom outlet and add back through the racking arm. You would want to move the product at a slow speed and dose the finings as mentioned before. I've found that transferring the beer works best, even from FV to FV. I guess the real question is why do you feel you need to add finings? In my experience certain finings tend to kill the head retention on my beers, even when used according to the recommended usage rates. With the appropriate timeframe and temperature drops you should be able to get a fairly clear beer after 2-3 weeks, especially if yeast in continually pulled of the bottom of the FV.Mike Jordan
