Brett bottling question

[SmellyFingers]

I brewed a Brett farmhouse ale using the Brett farmhouse strain from ECY. It finished at 1.004 so I Kegged the beer (did not carbonate) and planned to add priming sugar to the keg and then bottle the beer. I do not have a bottling bucket so I use a keg and makeshift bottling gun to bottle my beer.

Work has been hectic and we went on vacation so the beer has been sitting in the keg for 3 weeks at room temp. I checked the keg tonight and a good bit of CO2 came out when I hit the relief valve. Sure enough, it is partially carbonated, possibly around 1.5 volumes judging the appearance. Gravity reading is now at 1.002

My question is should I shake the co2 out of solution before adding priming sugar? I am going to bottle into heavy champagne type bottles; I want to bottle condition the beer at least 6 months.

It's going to be a little problematic dialing in your carbonation since you don't know exactly how much carbonation is in there. I would shake/purge it out as best as possible. Luckily with that style going a little on the fizzy side typically isn't a problem.
