Brewday - "Sunset Ale"

Notes
An Amber ale [Imperial Red Ale].  Named in tribute to the beautiful sunsets seen over our summer of camping.  I believe this batch marks my 4th attempt at the style.

Through trial and error, I've made a few recipe changes from previous attempts.  First, reduce the amount of Roast Barley.  A measly 40g for colour only.  I've reduced the total amount of crystal malt significantly.  Finaly, I've included a protein rest and lowered the sacc temp 2 degrees.  On the hop side, I've increased the total IBUs, added an addition at the 20 minute mark and will include some dry-hops as well.

28/08/2012 - Mashing

Second time using Gambrinus Pale malt for a base, second time with an extraction efficiency over 90%, 93% to be exact.  I've made some last minute recipe (hop) changes to account for the new anticipated OG (1.062).

Wort was chilled to 75F, took about an hour due to warm, summertime ground water through my immersion chiller.  Will need to build a prechiller for future summer brews.  Brewday lasted 5.5hrs, longer than normal since I had problems chilling.  S-04 Yeast was re-hydrated and  pitched to an aggressively aerated wort.

I'd like to brew this again but this time factoring in my proper extraction efficiency and actually coming close to my gravity numbers.

Here's the brew I ended with.:
26L@ 1.060, 22L into the primary.
57 IBUs
I updated the hop schedule (posted above) accordingly.

29/08/2012 - Primary shows signs of fermentation.

03/09/2012 - Airlock quiet.
