AG#15 Broadford Tomahawk IPA

Decided late last night to get a brew on and rebrewed the Tomahawk IPA that won me first place at the Northern Craft Brewers event at Saltaire Brewery back in May.  I only got to drink a half of it on the day, so hopefully I’ll be successful in recreating something close to it.

Original Gravity (OG): 1.058 1.055 (see edit note at the end of the post)
Final Gravity (FG): 1.014
Alcohol (ABV): 5.40%
Colour (SRM): 7.0 (EBC): 13.7
Bitterness (IBU): 65.4 (Average)

4.6 kg (86.96%) Maris Otter
0.300 kg (5.67%) Munich I
0.300 kg (5.67%) Pale Wheat Malt
0.090 kg (1.70) Crystal Malt 30L

28g Pilgrim (11.2% Alpha) @60 Minutes (Boil)
40g US Cascade (7.6% Alpha) @30 Minutes (Boil)
10g Columbus (Tomahawk) (16.5% Alpha) @5 Minutes (Boil)
40g US Cascade (7.6% Alpha) @5 Minutes (Boil)
40g Columbus (Tomahawk) (16.5% Alpha) Flame out (steep)
50g Columbus (Tomahawk) (16.5% Alpha) Dry hop

Single step Infusion at 65°C for 60 Minutes. Water treatments: Campden tablet (HLT), Gypsum (mash), Gypsum and Epsom Salts (Boil).  Boil for 60 Minutes. Safale US-05.

Strike temp of 74C and 13.00L liquor for 5.290kg grain.  Mashed in at 65C.

Mashed for 60 minutes and temp remained constant.  Sparged at 84C, 18.7L liquor.  I didn’t record pre and post boil volumes and gravity readings.

First hop addition of Pilgrim at 60 minutes, then US Cascade at 30 minutes. Added a protofloc tablet at 15 minutes along with immersion chiller, and further copper additions of Cascade and Columbus at 5 minutes.  Steeped Columbus at flame-out.

Collected 19L of wort post boil with SG of 1.058.  Cooled to 20C and dry pitched one packet of US-05 yeast.

A shot of the trial jar in the daylight.

Happy with the brewday.  Came up short again, but still using some borrowed kit and think I lost volume through, the boil; cooling and dead space (approx 4L).  Also, still lots of question marks for me re: mash efficiency.  One day I’ll get time to look at this stuff properly, but at the moment I’m just happy brewing and writing my blog.

I’ll be dry hopping this brew with Columbus (Tomahawk).

A few more photos of the brewday here.

Edit: Just realised a mistake. I changed my recipe on BrewMate and didn’t bother reprinting the brewday sheet.  Subsequently I misread my scribbled changes and my OG was actually 1.055, which explains how I came up short with 19L at 1.058.   I would have liquored back had I spotted this.

Original Gravity (OG): 1.058 (see edit note at the end of the post)
Final Gravity (FG): 1.010

Update: Dry hopped with 20g Columbus in the FV 17/06/12.

Bottled 24/06/12.
