Day off work, brew on, could be worse :)

Got my water treatment sorted for this one, thanks to the help from this forum.

Obligatory grain shot:

BIAB mashing can get quite close to the limit (all according to plan, honest!)

Cold day, so wrapped it all up nice and cosy for a 90 minute mash:

I tend to open the lid and give it a good stir every 30 mins. After one hour the temperature was down to 64.5°C, so bumped it back up to 66.

The nice thing about mashing in your kettle is that you might as well do a mashout and gain a bit of efficiency, as you've got to raise the temperature anyway. Here it is on its way to 78°C:

Aroma hops doing their thing:

Boil-off rates were very high today. Ended up 1.5L short at 1.053, liquored back to 1.049 before dropping lovely fresh wort into the cube for overnight cooling:

Leftovers:

And finally the WLP001 starter using 1L of wort liquored back to 1.040:

No rush, no dramas. Hopefully it'll turn out as tasty as version 1 did :)
 
nice one.....

not much fun in a brew day without dramas though is it................. :D :D
 
Just wondering about possible tannin extraction if you bring the grain up to a high temp. Might be worth some research.
Nice looking brew though by the way.

:lol:

More time for tea & toast though :) And it gave me a chance to blunder my way through a trial attempt at yeast washing...

Thanks, and yes, if anything I'm guilty of overresearching :) I think you're OK if you stop before 78°C? Hopefully someone will correct me if I'm wrong.
 
I BIAB and always mash out to 78C. Never had any problems with tannins.
 
Nice one, interesting combo of cascade and challenger. I thought about one of these with British hops might be interesting. Mitch Steel's book mentions a historic highly hopped porter with Goldings etc. keep us posted T
 
Looks good, ive got all the ingredients for this so might be one to do in the near future, just bought a couple of cubes too
