Brew Update
Well I did the brew yesterday and it went very well thanks to your help and advice
We had a taste at various stages, the last before filling the FV and what can I say, WOW

even without any alcohol it tastes, wonderful!!!
It's made me start to think about the next brew already...
I've put some of the details of the brew below, any advice or comments welcome
The SG was 1054 so not bad, a bit below Tribbs at 1064 and that was probably with just under the 20ltr finishing point, nearer 18.5 ltr's I think.
We ended up using 14ltrs in the mashing process which against the volume of grain of 13ltrs is just over 1:1
We hit the right strike heat of 72.5 in the tun before adding the grain and adjusting up to hit 67c ok.
I tested the temp. at the end of the 90 min mash and the temp had dropped only 2pts to 65c, is this good?
The A/A content was higher in the hop pellets, 9.6% which using a calculator we adjusted
20gm FWH
20gm @ 60mins at 8%
to
17gm FWH
17gm @ 60mins at 9.6%
I was skimming off the head/ scum before the wort came to boil at this point, as it started to boil more and more scum/hops started to come to the top and we decided to leave this as it seemed to contain the hop granules, hope this was right.
At 90mins of boiling I couldn't tell if the hot break had occured or not, may be because we were using pellets as opposed to whole hops it made the wort look more grainy than it was; when we pulled off a sample and set it down we could see the beer clearing instantly with the sediment dropping away so took it that all was good.
We used level tsp irish moss @ 15 mins to go.
At flame out we started the IC
The cold break was immediate it seemed, as soon as I started the IC we could see the beer clearing on the top.
We added the remaining 40gm's when the wort reached 65c
(wasn't paying attention as you said 80c)
The cooling to around 22c took ages, about 1h 20mins, perhaps I should have run the water through it faster? I bought it from h&g.
The hardest part now is waiting for the fermentation/ bottling / conditioning.....
Cheers,
Wayne.
