Epic Pale Ale clone

Recipe taken from "Can You Brew It".

Not sure how "cloned" my attempt is. I overshot the SG by 8 points! But more my fault than the recipe so here it is. Feel free to chime in :)

55L preboil

40L post-boil

75% efficiency

OG 1060 (should be 1052)
FG 1010-1012
IBUs 23.2 (True IBU is 45 aprox)
SRM 8.3

8.6kg Golden Promise 80%
1.1kg Baird's Caramalt 10%
360g Carapils 3.3%
720g Fawcett Pale Crystal 6.6%

Strike Water 30L - I added 48g of PH5.2 Stabilizer

Mash temp 68.5C (I hit 66.7C)

70min mash

Sparge Water 38L @ 80C

PreBoil Gravity 1050

90 minute boil

14g US Cascade 6.2%AA at 75m
28g US Cascade at 30m
68g US Cascade at 10m (plus finings - I used koppafloc)
85g US Cascade at 0m
Wait ten minutes
85g US Cascade - hot whirlpool for 10 more minutes

Cool to 18C and pitch, raise to 20C after 24 hours

Wyeast 1272 American Ale II - I used WLP051 instead - two vials into a 3L starter hand swirled frequently for 24 hours, then cold crashed for 9 hours before decanting 2L and pitching 1L yeast slurry split between two fermenters.

114g US Cascade dry hop dose 1 at 20C for 5 days - i just chucked pellets loose into the fermenter
114g US Cascade dry hop dose 2 at cold crash 4C for 5 days - chucked in loose again

I packaged 37L (18L into bottles and 19L into keg) at 2.4 volumes of CO2 stored at 20-22C
