Brew Evening 2 May : Springhead Bitter

On Friday night I brewed this:

25L Brew Length
Target IBU ~29
Target OG 1.041 – 1.047

60 Min Mash @ 67 degrees 3.0L per KG
60 Min Boil
Yeast s-04

5200g Pale Malt (98%)
85g Crystal Malt (2%)

44g Northdown (7.0%) 60 mins (~29 IBU)
25g Fuggle (4.0%) 15 mins
25g Fuggle (4.0%) 0 mins (steeped from 80 degrees)

1 Whirlfloc Tablet 10 mins

I changed a few things for this brew, hoping to get more body in my beer. I upped the grain bill and mashed more than I normally would for a 1.040 beer and stopped sparging at 1.020 leaving some of the sugars in the tun, this way I hope to have collected the best runnings from the mash.

I stopped sparging at 1.020 which gave me 21.5L at 1.050 topped up to 27L with unused sparge water to give a preboil gravity of 1.040.

I got 25L of 1.044 in the end, which is a 70% efficiency, so if I am happy with the results from this method i'll just base future brews on 70% efficiency and stop spargng at 1.020 again.

It has been suggested to me by a more accomplished brewer to try a 'no sparge' brew, so just working with the runnings from the mash!

I do fancy giving that a go, i'm coming around to the opinion that chasing high efficiencies could be a detriment to the quality of the beer.

We will see!

It's currently sat in the fermenting fridge at 19 degrees.
