I seem to have got the hang of the King Kegs. I finished the second of the two 40 pinters a few days ago.
Somewhat alarmed that I shared not a drop and started on them at Christmas and now they are gone but hey. Both kegs kept the beer fresh. It was a learning experience to know how much gas to put in but turned out super useful that I installed pressure meters in both lids so if the gas leaked out I would know.
Both kegged brews were great. In general terms I bought some bulk malt liquid to add to the tins and some hops , one brew had actual hops the others an extract. I filled my fermenting buckets with water and put an oxygen bubbler in each one to aerate the water and help drive off the chlorine before commencing brewing. .
I adjusted the PH too, using lemon juice to bring the water down to 7.0 (from 8.2). When the brews were ready to be kegged (and a third brew bottled) I was a bit disorganised, plus dismayed that the money for the kegs could have been wasted as when I put the first brew in it would not hold pressure then my gas ran out. So I had 120 pints in three buckets needing to be racked off, plus me having covid and the place a mess.
I kept at it. Ordered new valve rubbers for the kegs. I added sugar to the keg that had beer in it for a secondary ferment to get a bit of gas over the top to keep it fresh. I then had a seemingly endless process of cleaning the first bucket, racking off another brew into the sterilised bucket and repeating till all were off the yeast. I had to clean and sanitise 40 bottles too. My bath was full of stuff for weeks.
I got a load of gas bottles and rubber seals and all was well after that. The bottled beer was left in bulk the longest and isn't the best. I'm drinking it right now though.
Both the other brews were better than down almost any pub around my way. Well there is a Youngs pub that does superb beer and fab food but their 6 quid a pint is too much for me. I am going to persevere with the King Kegs and am thinking of just getting proper kegs and dispensing equipment as I really like the convenience.
Hell for me would be an endless bottle washing job.
