So I just picked up my beer gas mix tank to finally put my nitro tap to use. On the nitro line I am gonna be serving a full 5 gallon keg of 14% Wheatwine that was aged in a Maple Bourbon Barrel. Obviously thats a great choice for nitro service, especially on a nice warm Pennsylvanian summer day. The beer obviously should last a while as I'll only be serving some pretty small pours (mostly). If I wanted to pull the beer off the nitro tap and bottle the beer at some point with the beer gun, could I just set the keg out at a room temp, venting the keg occasionally to release all the co2 and nitro out of solution? Would this process take longer than degassing a keg of Co2 carbonated beer? What would happen if I just vented the headspace on the keg and attempted to bottle with the beer gun as usual with a low c02 push? Would the nitro just knock the co2 out of solution while bottling leading to a bottle of foam? Bit of a Nitro noob here, but really would love to get this beer into bottles after a few months of nitro service if possible. Thanks in advance!!
http://byo.com/malt/item/928-is-it-possible-to-bottle-nitrogen-charged-beer okay, after some searching I found this. So if I bottle the beer right after nitro dispense, sounds like I'll end up with just a pretty flat beer, which makes sense since co2 is only 25-30% of beer gas mix. So I'm thinking after I'm done with having this beer on Nitro, I can vent the headspace, and hook up to normal co2 at whatever setting I want to get whatever co2 vol. I want in the keg, then bottle with the beer gun as normal??
You would disconnect the N gas mix and degas the keg. N does not really dissolve in liquid. It is, in your system design, needed to push the beer through the stout faucet. Once you have degassed the N from the headspace you can apply 100% CO2 and carbonate as typical. What you are describing, flat beer in a bottle from a Nitro faucet, is exactly why it is a terrible idea to purchase a growler of nitrogenated beer. The beer is not very carbed to begin with and it loses its creamy N head quickly. Cheers.
