It's been a long time since I've bottle carbed anything but I've got 2 coming up that have spent extensive time lagering that I want to bottle. I racked them to a clean keg and I'm planning to repitch and carb with corn sugar.They were ale temp fermentations but have been in degassed kegs at 34*F for the last 3-4 months. Does this change the way the math works as far as how much sugar to add? I'm thinking no but as mentioned I haven't bottle conditioned anything in probably 4-5 years and with the time I have invested in these I don't want to screw it up!

There may be some CO2 in solution cause of the cold secondary, but it's probably not enough to make bottle bombs. I think there's enough fudge factor in the priming sugar calcs and measuring, that you'll be close enough.

This is a pretty good question. I'm assuming that you purged the headspace in the keg with CO₂ after you racked the beer, correct? If so, then a good bit of that CO₂ would have dissolved into the beer when you chilled it. However, if you warm it up before you prime it, that CO₂ is going to come back out of solution. So in that case, I'd use the temperature that you warm it up to before priming. If not, then I'd use the temperature you lagered at.

Correct. I purged the keg with CO₂ then racked the beer into it and again purged the headspace with CO₂ and chilled the keg.So it sounds like the way to be sure is to bring it up to room temp, blow off whatever CO₂ is in the headspace then prime and bottle away.

Sounds like a good reason to buy a beer gun. That seems like a lot of work...........

I agree. Dan does bring up a good point though. No CPF/Beer Gun?

Correct no CPF or beer gun. Though I do know someone who has one....The 1 is a braggot and probably would not benefit from bottle conditioning but the other is a Belgian quad. Maybe I'll carb and beer gun the braggot and just do the quad the hard way since I want to keep it around in bottles for the next couple years.Thanks DJ. I was wondering if I was making this more complex than it needed to be. It takes the right person to point that out sometimes

If you racked the beer and purged with CO2, how much pressure is it under? It is trivial to calculate the C02 levels in the beer given the temp and pressure.BrewBasser

I have a beer gun. Send the keg to me, and I will.....wait what was I saying?I agree. A beergun would be a good move at this point. You could also bottle other stuff that is either carbed or uncarbed (like still meads etc). Great investment. If not, I agree, I would warm it up and let the co2 equilabrate at the higher temp brefore proceeding. You will have to anyway to allow the yeast to do their thing.

Here ya go: https://hbd.org/cgi-...rbonation.htmlI might add 1 gm of dry yeast per 5 gallons to ensure good carbonation.

1 atm

[jayb151]

The 1 is a braggot

Strangebrewer,That Braggot was awesome! Did I ever send you any of my tasting notes?!
