Hopstand American Red Ale & Jamil's Immersion Whirlpool Chiller

Long time no post! After moving from Portland Oregon to Broomfield Colorado it has taken some time to settle and get back to brewing again. For my first Colorado homebrew I have decided on an American Red Ale in honor of the hoppy and citrusy west coast ales I have become accustomed to. With the equivalent of nearly four ounces of hops in a hopstand for 45 minutes at 150-160 degrees Fahrenheit I am looking forward to tasting this! Back in Portland the Laurelwood Brewery serves up a delicious west coast red ale that strongly balances citrus with delicious malt. 

Laurelwood Deranger Imperial Red Ale

From the brewery:  
Deranger Imperial Red Ale
Here is the beer you've been waiting for! Organic Deranger is our renowned Imperial Red Ale. It is our Free Range Red that is made much bigger, with tons of flavor and aromatic hop additions. It is a beautiful red color with a chewy caramel malt backbone that supports the complex layers of hop flavors.
8.6% ABV / 100 IBU / O.G. 20° Plato

The thing that struck me about this beer was the soft hop presence in the brew. It claims to be 100 IBU's, but tasted more like 30-40 IBU's. So I set out to brew up something similar using my Brew In A Bag setup.

It has been rumored that Laurelwood used an extensive hopstand on this brew and no bittering hops. I wanted some bitterness so I decided to first wort hop with Simcoe and leave the rest of my hop additions until I had cooled the wort to 160. What I noticed was that as the temp went down on the kettle so to did the hop aroma decrease. I am hopeful that more hop aromatics are staying in solution with this lower temperature. While the hops were infusing for 45 minutes I continuously whirlpooled the 212 degree wort.

Taking inspiration from Jamil Zainasheff at his site Mr. Malty, I decided to build a similar immersion whirlpool chiller. This was its first test run and it performed well except the trub pile in the bottom was not a pile, but rather a pancake that lined the entire bottom of the kettle. Perhaps I just had so much hot and cold break in my little 7 gallon pot that it took up too much space to "pile up"? The video below is of me whirlpooling the wort near its cool pitching temperature.


Here is the recipe, it is set at 70% efficiency for a final volume of 2 gallons to ferment. I will post back with tasting notes:

Ran grain through mill at LHBS twice.

Hopstand for 45 minutes while whirlpooling between 150-160F

Mash out at 1.036 gravity points per 3.10 gallons water
36 X 3.10g = 111.60 gravity points

Chilled to 72F and let stand for 10 minutes before slowly running off.

Pre-boil gravity reading: 111.60 Gravity Units / 2.00g = 1.056 Original gravity

Post boil chilled gravity reading: 2.30 galons X 46gravity points = 105.8 / 2 = 1.053
