well...
firstly, I think I let the water go low on the mash... so there wasnt' that much wort.
Then I had to improvise a sparging system which was a bit lash up in the back garden on a table using a colinder to hold only half the grain and my brew kettle to provide the water. I then had to sparge the other half of the grain but i had no proper sparge-head, so I had a stream rather than a shower of sparge water. I guess this created channels and I also kept moving the grain around to get some water under it, which doubtless stirred up some less desirable constituents.
I also noticed that the grain was still quite sweet after I had finished sparging.
Also... because the colinder was so small, it kept overflowing and running into the colletor barrel.
Then I boiled it (without checking gravity or collected quantity) that went ok as I have a good bruheat barrel.
Hops: that went ok
Then I had to transfer it and cool it. I had no hop strainer, and no means of cooling, so I had to sit and watch the 1ml per second flow that managed to get past the hop-clogged tap.
I'm sure this let a ton of oxygen get to the beer and took so long to cool down to pitching temperature.
When the temperature dropped, I pitched with my yeast starter which went ok.
I left it a week and transfered it into fermentor No.2 but I noticed there was way too little water, a consequence of not paying attention to the amount of wort I collected.
So I figured I could boil a few pints of water and top it up a bit. I did let it cool so as not to murder the yeast.
I left the lid on the secondary fermenter on, but not tight (no airlock), so I suspect the main source of contamination was then, as the protective crust and layer of CO2 was gone.
After about a week the 'beer' went a distinctly darker colour, and tasted quite horribly like vinegar, the SG wouldn't drop below 1018 either. I've not figured that one out yet.
I put some in three bottles to experiment with carbonation. After a couple of weeks i opened them and there was no cabonation at all... just a dark brown cloudy liquid that was only any use to make pennies shiny...
All in all, rubbish....!
So.... back to the books and the net. I made myself a hop strainer from a copper pipe with many holes drilled in it, this worked brilliantly.
I also made a sparger using various bits of hose and a watering can rose, (also very effective) and i aquired a proper airlock for fermenter No.2 and wrote many notes before starting.
This time:
-I checked and collected the right quantities of wort and sparged wort.
-Checked the gravity
-Made a wort cooler using 10m of copper pipe and some hose and chilled the wort very quickly.
-Pitched
-kept everything covered.
-I'm only at first fermentation, so I hope I can keep up the good work.
That leads me to a question: during this brew when I found I was losing water through evaporation during boiling, I covered up a bit to minimise the loss, but is it ok to add a little water during the boil to make up the difference? I did run a kettle or 2 full of hot water of the hop bed to make sure I collected the right amount of wort.
Brew 1 was a bit of a catalogue of errors, but hopefully this time will be alot better.
Thanks
