Robust Rye Porter Brewday

Back to a dark beer after a string of light and hoppy beers. This will be my first straight porter, as all my previous porters were brewed with smoked malt. I used the recipe from Brewing Classic Styles with a couple of modifications, since I had on hand a pound of rye malt with no immediate plans to use it, so I substituted it for some of the base malt. Secondly I had some spare Crystal 60 lying around, so I tossed it in the mash instead of C-40, and reduced the amount a bit since I figure C60 will give a sweeter note that C40. As for hops, again it was a substitution to what was in my fridge. Now onto the good stuff:

Robust Rye Porter
6# Briess 2-Row
1# Light Munich
1# Rye Malt
8oz Chocolate Malt
7oz Crystal 60
4oz Roasted Barley

Warrior,  .35oz, 15.5%AA, 60min
Willamette, .5oz, 4.7%, 10min
Willamette, .5oz, 4.7%,  5min
Willamette, .15oz, 4.7%, 0min (finishing a bag of hops)

Mash at 154F

US-05

Expected OG / FG / IBUs / ABV: 1.063, 1.016, 28, 6.1%

9/5/14 - Made a starter with recycled yeast from the latest APA

Brewed 9/6/14
Hit my mash temp well, but oversparged and collected 4.75 gallons of wort at 1.051FG. Boiled for 30 minutes before adding hops to compensate.

Everything went well - I even took the gravity at flame out, using my refractometer and volume using my measuring stick. I was over gravity and volume, with about 3.5 gallons at 1.068.

Cooled wort using fresh groundwater to 85F, then placed in basement to reach pitching temps.

Several ours later, decanted most of the starter beer (it had fermented over the past day) and pitched the yeast at 70F.

9/7/14, 2pm - active fermentation with the carboy sitting in a pale of water at 70F, 68F ambient air.

FYI, here's a picture of my cooling setup. The hot wort leaves the kettle through the stainless valve and the high-temp tubing into the march pump, the returns through a whirlpool arm attached to the wort chiller. In this picture the garden hose is supplying fresh water, which is filling the grey bin. Normally, I would use the submersible pump in the bin to re-circulate the cooling water through the chiller, but water in that bin gets really nasty after a while, so I occasionally dump it. Also, in this picture I have managed to balance the chiller just right so that it does not fall over onto the side of the pot.
