Default Forced Carbing. What am I doing wrong!

Hi Everyone,

I've been trying to force carb for 3 batches now. All with very minimal effect.
Of the 3 beers I have force carb'd, they all have the same problem. Alot of foam and head, but very little carbonation in the actual beer.

I have a 20# co2 tank setup to a corny keg. The last batch a Blueberry Hef has been on 35psi of CO2 for the last 2 weeks. I don't have a kegerator so I have to carb it at room temp. average room temp has been 65-70 here.

I tried a small sample yesterday. I shut off the co2, changed it to 8psi and then bled off all the extra co2 in the corny tank before turning on the co2 again at the 8psi.

I have the corney keg hooked up to 24in of line and a picnic tap. (could the short line be causing the foam?)

Let me know if you need more info.

I have best luck with a 6 foot serving line.

Do you chill keg before pulling a sample? If not you will get a big glass of foam. I only have a chest freezer which I can't modify so I will put in my keg for 2 hours then enjoy.

One of the issues with room temperature carbing is that while it works, dispensing warm beer is usually a foamy mess.

First, at 30 psi, you need like 30' beer lines for the proper restriction (reducing the pressure for serving doesn't really work) and secondly, warm beer tends to foam more anyway.

If you don't have a way to serve the beer cold, you can try going with a super super long line and see if that works. I do it with soda, and it works ok. But a 24 inch line will never work, even if the beer is cold. I use 10' of line in my kegerator, with the regulator at 12 psi and at 40 degrees.

So it could be the serving line. That was the last variable I was considering. I'm gonna pick up a long line and see if that helps. Thanks for the help. I'll let everyone know how it goes.

Also, 35 psi for two weeks just screams over carbonation. Sounds like you over carbed it, big time

I guess at room temp 35 isn't too terrible, but it still sounds overcarbed if you're foaming. Leave it off the gas and purge the keg every time you walk by it for a few days. Check it after a few days of leaving it off the gas and purging the keg and see if that helps. If it does, then you're overcarbed. If it doesn't try longer serving line.

Read the original post. He's force carbing at ROOM TEMPERATURE, not fridge temperatures. 35 psi at room temperature is just fine for carbing.
