Hi there MICK.
Just noticed that no one has replied to your post and thought I’d offer my very limited suggestions.
I’ve been brewing for 4 months so I’m still very green when it comes to the tech side of things but here is something I found.
View attachment 115456
I’m thinking of this kit but using the Coopers Dark Ale instead.
Replacing the 1KG LME for a 1KG DME
No crystal malt grain.
Do a 10L kettle 30min boil
At boil, roll off to about 80 degrees and add the DME and 250g golden Syrup while stirring it in.
5 min mark add 15g (or more) Fuggle hops.
Flame out at 1min
Cool as quick as possible (down to about 25-30 degrees) and into your fermenter.
Store some water in the fridge overnight to use when cooling the wort.
Dry hop a further 15g Fuggle at about day 4 and do a gravity test on day 7 should be good to bottle on day 8.
Like I said. I haven’t done this one or tasted it’s clone beer.
Good luck.
