Regular.
So, after much discussion and advice on improving my BIAB efficiency, today was brew day with a focused attempt on improving things a little.
Exmoor Beast clone.
The recipe calls for
6020 Pale Maris otter
545 Crystal Malt
250 Chocolate Malt
The hop additions are not important here.
I upped the MO to 6800 to compensate for any Biab efficiency loss with a view to hitting a target OG of 1064. According to my notes this is what I got last time with the all made up kit from Worcester hop shop . Note, the kit came with the regulation 6020 MO ... that got me 61.5%
33L strike water to 73 degs
Doughed in carefully the grain bill.
Mashed for 90 mins with three good stirs.
Temp post mash, 64degs.
Left the bag in the wort whilst back on the burner and stirred occasionally whilst the temp came up to 80 degrees.
Swished the grain around in the bag for 5 mins before lifting and tying off above the pan whilst it drained and the gave it a real good squeeze, not forgetting grain absorption from 6.8 kg can be quite a bit...
75 minute boil and a rapid cool before dispensing 20L into the fv. I'm never sure wether to drain the dregs inc all the hop debris. I use a Bazooka hop filter in the pan but sometimes I'm tempted to drain the dregs through a sieve for a further litre or so...
Anyway, moment of truth. Quick sample into the trial jar shows me 1058 !!!!!!
WTF !
I make that 49.6% efficiency![facepalm :doh: :doh:](https://s3.eu-west-2.amazonaws.com/norfolkbroadsnetwork.aws/emoticons/facepalm.gif)
I give up........ after all the concentrated effort to improve things, it got worse !
So, thinking about it. I use a 2L plastic jug to scoop the grain from the sack. I have double checked the weights of a nearly full jug at 850g on what I assume to be accurate Salter kitchen scales, so 8 jugs gives me 6800g.
I really can't think of anything else other than the grain in the sack is a mix of semi crushed grain and some not so crushed grain. This is the second brew from the sack so maybe the more crushed bits are at the bottom....
I'm off for an (inefficient) beer ...
Anyway, ''twas truly a beautiful day to be mucking about and brewing beer here today.
I've added a couple of pics.
