Hello. I currently have a Hambleton Bard s30 co2 cylinder that's pretty full, as the king keg I bought it for doesn't hold any pressure (believe me, I've tried everything with the keg!). As I'm happy bottling and have purchased a bottling bucket, I thought it might be a good idea to spray some co2 in the bottling bucket, to create a protective layer over the beer as it's transferred... as co2 is heavier than air, it should stay put enough to do this. Might anybody know of an attachment/technique for safely releasing a short burst of co2 into the bucket before siphoning? I thought of using the lid off the king keg, but think that might be a recipe for freeze burns and a world of misery! I'm probably overthinking this, but thought it might be something good to try for any beers that are particularly sensitive to oxidisation (neipas seem to be one of these from what I've read) Any help/suggestions will be much appreciated!
