Carbonation of Kegs - What do you do?

Post #1 made 8 years ago
We've had several threads over the years on carbonation. One thing those threads have shown is that there is a massive variance in recommendations and techniques*.

We've nailed tricky stuff like this before so we might as well do it again.

Can you please click on the link below that applies to you or that you have experience in, and then follow the instructions there to give us your "numbers" on what works or has not worked for you?

[center]If you keg and force carbonate (fast or slow)

If you keg and naturally carbonate

If you bottle[/center]

* This thread is probably the best for showing the extent of the variations we get just on bottling.

** Use the file below to help you determine the correct carbonation level for your beer style. (We received kind permission from the AABC to use the numbers from the attached sheet several years ago.

If you force carbonate your kegs, please select and copy the Code below, paste it into the Quick Reply box and complete the details. Two examples (fast and slow) follow the code.

Code: Select all

On a scale from 0 to 10, if 5 meant the beer was perfectly carbonated for the style and 0 meant the beer was completely flat and 10 meant the beer gushed or exploded, how would you rate the carbonation of this beer?:

Overview

Beer Style: American IPA
Original Gravity: 1.065
Final Gravity: 1.015
Desired Vols CO2: 2.5
Metric or US Measurements Supplied: Both

Yeast/s, Times and Temperatures

Main Yeast: US-05
Type and Amount of Yeast Used when Priming (if any):
Wort Temp 72 hours before Carbonating: 18 C (64.4F)
Wort Temp at Transfer to Keg: 6 C (42.8F)
Days Allowed for Carbonation: 3
Avg Temp during Carbonation Period: 6.0 C (42.8 F)

Volumes

Volume in Fermenter at Pitching: Can't remember
Volume into Secondary (if used): Not used
Volume into Keg: 18.7 L

Priming Information

Process Used: You have to be careful on this as things can back-fire on you and I don't want anyone to follow my numbers as I'm not sure on my conversions etc. Say if I will be dispensing at 110 kpa (16 psi), I basically set my regulator to a high pressure (400 kpa / 58 psi) as my kegs can handle that. I then lay my keg horizontally and rock it, listening to the regulator and lowering it gradually. If you lower it too fast, beer will flow back into your regulator and cause all sorts of problems. Once I get down to 110 kpa (16 psi), I keep rocking until I hear no sound. Then I put it in my dispensing fridge and generally leave it for three days.

Results

On a scale from 0 to 10, if 5 meant the beer was perfectly carbonated for the style and 0 meant the beer was completely flat and 10 meant the beer gushed or exploded, how would you rate the carbonation of this beer?: 5

Notes and Personal Preferences

Notes: Be careful when fast force-carbonating. It's easy to make significant errors.
Personal Preferences: I probably prefer moderate carbonation in my beers. I'm not a fan of flat beers or real fizzers.

Priming Information

If you naturally prime your kegs, please select and copy the Code below, paste it into the Quick Reply box and complete the details. An example follows the code.

Can you describe the humidity (cold and hot climates can both be humid or dry) in your area? In other words, do you think your priming sugar is really dry, can it get a little damp or something in between?:

Can you describe the humidity (cold and hot climates can both be humid or dry) in your area? In other words, do you think your priming sugar is really dry, can it get a little damp or something in between?: A lot of the time of year, it is really hot and humid here. I keep my main lot of sugar in an air-tight container but, in my everyday container, it often clumps. I always prime using sugar from my air-tight container though.

Notes and Personal Preferences

Notes:
Personal Preferences: I probably prefer lower carbonation in my beers. For example, I brew more English styles than lagers or pale ales.
