Quirky English bitter:
NOTE: A previous and conventional batch of bitter had 93% MO and 7% medium crystal, EKG and Willamette hops, and West Yorkshire liquid yeast, and was mashed at 67. Nice balance of ester and malt flavours but not to my tastes a summer brew. So I thought I'd mash a bit lower, lower the caramel in favor of toast and melanoidinn, use a slightly more neutral yeast and bring the hops a bit more forward.
22 L starting boil volume and 22 L final beer volume.
BIAB mash at 66 C for 75 minutes and batch sparged:
3.5 kg Simpson Maris Otter
100g Bestmalz melanoidin
160 g home-toasted JW wheat malt
40 g Dingemans Special B
75 minute boil
@ -60, 28g of Challenger
@ -17, 12 g Challenger, 12 g Willamette and 12g EKG
After cooling to 79 C (below DMS formation temperature) with cold sterile water, added 8g each of Willamette and EKG. Delayed further cooling for ten minutes, then cooled fast.
OG of 21L 1.048, mash efficiency 88%
Fermented w. US-05 for 18 days in primary, starting at 17 and rising to 20.
Bottled after adding to fermenter 1 L boiled water with 120 g cane sugar, and after cooling 2 ml Challenger “liquid hops” (hop oil in solution).
A sample tasted at bottling was very promising, but that early reading can deceive.
