Naked City Collaboration RIS

Back in the fall of 2011, the Washington Homebrewers Association (WAHA) sent out an email to all of the Washington AHA registered homebrew clubs to see if there was any interest in working on their own commercial collaboration brew for the NationalHomebrewer’s Conference ( Bellevue, WA in June 2012).   Our highly motivated club, the Homebrewers Guild of Seattle Proper, jumped at the opportunity and responded right away.  Unfortunately it seemed as though WAHA wasn’t quite as ready to begin the process as they originally expected, and so rather than waiting until their anticipated start date of Spring 2012, we began the process on our own.  One of our first choices, and a favorite brew pub among many of our club members, NakedCity seemed like the ideal candidate for such a collaboration project.

Although we would have been more than happy to brew anything with Don, the brewer and owner of Naked City, we decided that as a club, we should come up with a few ideas to present to him beforehand.  One club member had recently picked up a 30 gallon whiskey barrel from the Woodenville Whiskey Company which was recently drained of their Harvest Release American Whiskey.   We had been planning on using it for a club project, but with the advent of a collaboration brew and a little time on our side, we thought it would be fun if we could brew a larger batch of beer on Naked City’s system and then age a portion of it in our whiskey barrel.   If it comes out too strong, we can use some of the standard version to blend back and if not, we’ll have a fun, 100% barrel aged collaboration brew to serve at NHC.

With the decision made to use the whiskey barrel for the Naked City project, the 8 of us in our club next debated about what to fill it with.  A multitude of ideas were tossed about, but in the end, Don and the other members of our club decided to go with the always-popular-among-beer-nerds Russian Imperial Stout.  Fitting of his completely laid back style, Don left the recipe formulation completely up to us and so in designing the grist and recipe, we went with a combination of grains that leaned towards a chewy, chocolate base with a mild residual sweetness and just enough clean bittering hops to keep it from being cloying.   One of our secret ingredients that we were planning on using was Golden Naked Oats, which is a mild caramel malt that adds a touch of nutty sweetness along with a velvet like texture.  Unfortunately on brew day, after adding all the grains to the mash tun, we realized that flaked oats were added instead of Golden Naked Oats.  With 7% of the grist once scheduled for this caramel malt and now substituted for flaked oats, it’ll be interesting to see if the roast is now running strong in the forefront or if there’s enough residual sweetness to balance out the hops.  We ended up mashing at 154° instead of the originally planned 149°, and with the increase in temp, hopefully the slightly less fermentable wort will result in body and sweetness closer to what we originally intended.

All in all it was a great brewday at Naked City and I can’t wait to see how both the barrel-aged and standard version turn out.  If by chance you’re headed to NHC this year, come check us out and see for yourself what you think of our collaboration brew.

1/13/12 – Brewed with the club and Don at Naked City

Don had all the grains milled and ready to go.  Doughed in and settled at a rest temp of 154°

According to our calculations, we needed about 2.0 grams per gallon of baking soda to reach our target mash pH of 5.3.  Taking it slow, we added in half the amount (145 grams) and then measured the pH…6.0.  It should have been way below this, so we opted to not make any more additions.  After realizing the grain issue, we speculated that the lack of 30 lbs of crystal malt caused our initial pH to be higher than expected.  Adding the 145 grams of baking soda only increased it further, so without it, we probably would have been in about the perfect range.

Boiled for 2 hours with mineral and hop additions as noted above.  Minerals went in at 60 minutes.

Whirlpooled for 30 minutes, and then chilled as we racked off (using plate chiller).  Oxygenated inline and pitched yeast at about 70 degrees with fermentor set at 68.

2/9/12 - Beer was transferred out of fermenter and into barrel and brite tank.
