2011 International Homebrew Project – Brewday

This is the International Homebrew Project brewday notes, shop the no pictures version. Rick of CandianBrewer fame came over for a big batch brewday. We did a bit more drinking and bullshitting than photo taking. Rick brought over a growler of his Lees Stout for some proper motivation. That is one tasty session stout…

All in all, a pretty decent brewday save for a couple stuck mashes. I’ve had this problem off and on over the last few batches and don’t quite have a handle on it. Thankfully I’ve learned that stirring and letting it settle for 5 min usually gets the grain bed reset. Recirculate a bit to ensure clarity and then off and running (ha!) again.

I was able to get all the proper ingredients at Northern Brewer. Simpson’s Medium Crystal, Crisp Amber and Brown malts. I had some Fawcett Roast Barley from a group buy earlier in the year. I didn’t get the Mild Malt, but did use Fawcett Optic to ensure we get that solid malty base.

The Invert No 3 was part of a big batch I made a while back. It took a half hour of soaking the container in hot tap water to get it loose enough to pour. Stuff is awesome – sticky-icky goodness of toffee and medium fruits.

The only missed number was the extra 10pts of gravity heading into the kettle. Somehow these 10 gallon batches actually boost my efficiency up from 75-80% to 95%. Cute! We decided to stay the course and avoid any course deviations to make sure the balance and mouthfeel weren’t compromised. The unfermentable lactose and Wyeast 1318 should keep the attenuation down – looking to finish around 1.025 or so for 5.16% ABV.

The mash-out was a bit different than the usual infusion… Promash was telling me it was going to need 10.9 gallons in my 10 gallon mash tun. So, decoction mash out it was. Not the first time for that – I tend to do this for the amber and dark lagers for extra flavor. So enough poetic waxing and onto the notes…
