Mad Boris MkII (Double Brewday) - 16/01/2010

Post by coatesg » Sun Jan 17, 2010 1:27 pm

Second brew of the day and what a nightmare. This was an almost repeat of Mad Boris, but up scaled using my new 44L tun, slight change on the hop schedule (more EKG, subbed pilgrim for target).

Recipe was:

10kg Cocktail Pale Malt
625g each: Wheat malt, amber, light crystal, chocolate, roast barley
330g Brown Sugar

240g EKG 4.6%
55g Pilgrim 9.4%

The mash went very well, abd the valentine I'd put on this tun worked very nicely indeed. However, I laded up with a huge amount of wort, and even trying to follow the Durden Park advice of splitting batches, boiling up to 15 points below, recombining and then boiling didn't work particularly well. Coupled with an element that kept cutting out, it took about 4 1/2 hours to boil down to the right gravity using one element, the cooker hob, and a separate pan on the hob to boil smaller batches down. The break material seemed to be very low indeed - probably as a result of the long boil (long boils weren't unheard of back in the day I seem to recall from one of my books - the protein that goes back in solution produces a "nutritious" drink :lol: )

Then the run off kept clogging with hop bits that found their way through the strainer - in all a complete nightmare. Though, in the end I landed up with about 35 litres of wort at 1.088 (22.5brix) so we're fairly happy with that - pitched 33g of S04, and it's starting now to produce the fingers of foam I seem to get with these high gravity brews.

In all, one hell of a christening for a new tun, a bit of maintenance on the boiler required and a massive tidy up for me now :oops:

This morning woke to find that the 60L fermenter was completely full of foam, and has accumulated a pile of foam on the top of the fermenter after blowing through the airlock. Easily 40 L of foam been generated here.... it's now sitting in the bath...

OK- first sample tonight - it's definitley moving along the mellowing out process. Strongly bitter, quite strong heavy roasted flavours (almost smoky at times), and still needing time for everything from the malt to start to develop and mesh together. Definitely not undrinkable though!

Importantly, the conditioning process seems to be working well - there was a little gas on uncapping, and a low to medium level of carbonation which should be perfect in 6 months or so when I think I'll start having a bash at this one.

Only 50 pints of this left then ;) (When racked, it came out at 1024 - 8.5% ABV - 0.5% lower than Mk I, but just fine by me :)

Graeme
I quite fancy a pint of that right now.
Any chance of some pictures of this 44L tun?

Ok - here goes - the first is a pic of the valentine, and the second the manifold inside:

What was your actual planned brew length on this?

Working on 75% efficiency, it'd be about 33L. I bottled up 50.5 pints in total (so 29L or so). Lost a load with the hops, some with clogging runoff, some that blew out of the airlock, and a fair whack of yeasty trub in the fermenter! The 35L estimate was probably a little over estimate (not calibrated the fermenter), but the final result is probably about right for the grist.

I'd put the numbers into BeerEngine and come out with around about 34L, so not far off..

Good beer was it, is it?
