Anna's Adventures in Kegging
So it's been just a bit busy over the last week but I finally couldn't put it off any longer, I faced up to the box of interesting tubes and shiny metal things... and tackled kegging
I've been a bit intimidated by the whole scary pressurised cylinder and leaks thing, not to mention connecting up metres of tubing, metal things and kegs. Not to mention that the CO2 cylinder and keg purchases had been a bit of an impulse, a sort of 'seemed like the right thing to do' back in November. I'm blaming you bunch for making it sound simple and that
@Hazelwood Brewery for setting the aspirational bar so high! I'm generally fine with electrics since they don't leak, but plumbing and the risk of leaks has always concerned me, not helped by having lived in homes which had some pretty unpleasant water damage events. it's in that context I set to with the box of bits that Jonny had kindly sent from BrewKegTap, together with a sharp craft knife in a friggin freezing garage (4 deg indoors!).

Things I've learnt so far:
- I thought 1.5m for gas lines from the cylinder and to the kegs might be too short... nope it's probably too long.
- That thing that splits the gas into 4 outputs is called a manifold... who knew...not a silver thingy with red bits, which is how I still think of it.
- Attaching the regulator to the cylinder needs the white washer to be attached to the regulator first, if not it leaks lots loudly.
- You need really quite a big spanner and to feel a bit brave to tighten up the regulator.
- Yes the CO2 pressure is scary when you turn it on to flush the outlet, loud and a bit eeek!
- John Guest push fittings are officially the coolest thing . Oh wow I really like these, and I found out you don't need to tape the screw joints.
One of the things that has helped was spending some time learning to move sanitiser solution around keg to keg using pressure and connected beer lines before filling a keg with beer. This has the benefit of sanitising a couple of kegs and it's quite fun and feels like a very grown up water toy with foam and bubbles.. well apart from it being friggin freezing (yes I know I've already said that - it was really cold!
)

So after I'd played with the foam for long enough I siphoned the long waiting fermenter full of Nelson Sauvin pale ale into it's new home, attached a gas line and set my carbonation pressure to 10psi. Checked all the joints and no leaks found, tidied up and retreated to the kitchen with my frozen fingers... which turned out to be a bit of an advantage since I was making pastry for a quiche for dinner and there was next to no risk I was going to melt the butter. (It turned out a rather lovely short crust despite having to improvise with wholemeal flour and a bit of self raising after discovering I didn't have enough plain flour). Yes kegging is a lot lot faster than bottling, I did have about four 500ml bottles worth left over which I'm afraid I just bottle primed with a very approximate teaspoon of dextrose each. Rather interestingly the FG was 1.009 so overshot a bit on the attenuation but not by too much. It tastes nice even now despite having been cold crashed for several weeks at 2 deg C while waiting for me to extract my digit and get on with moving it in to a keg.
I do have one lingering question, well one at the moment anyway. The pressure on the regulator seems to suggest the cylinder is almost empty as shown in the picture. It still feels really heavy and I hadn't opened it till Sunday and it's not gone down since other than a tiny bit with the exploits with the Chemsan. Have I done something wrong or should I be going back to the supplier about this?
