I Don't Believe In New Year's Resolutions

... but this year I'm making some brewing resolutions for the 2014 season. Jeremy and I are good brewers. We win medals in competition. We can generally turn out consistent beers from batch to batch. The number of hours I've devoted and the amount of educational material I've devoured keep mounting.

But we're still not great. We don't often take a category gold, and we've never won a best in show. Hop character is still hit or miss in our beers. The occasional batch is a clunker and I'll dump it or pawn it off on unsuspecting friends during one of our "family" dinners.

And so, I want to get better. So over the winter I've ruminated on and off about our process and what we can change for the positive. Here's the list:

1. Make our starters earlier and bigger. I tend to do most of the yeast management and sometimes those poor little critters only get 24-36 hours of time to warm up and get ready to chew through some sugars. We also only have two 2000mL flasks and one stir plate so they end up splitting time on it. We're going to buy a couple of 4 liter flasks and a second stir plate to really handle the pitches we need for lagers and higher gravity beers.
   
2. Make the same beers until we get them dialed. We've brewed our way through a good number of the recipes in Jamil's Brewing Classic Styles. This has been wonderfully informative on the ways different ingredients play in different styles. But the only beer we've ever scored in the 40's on was the ginger wheat recipe I've brewed over and over and over again through the years. Slowly tweaking the recipe every time has gotten it to the point that it's really balanced, drinkable and has a huge amount of flavor.
   So we're going to make beers we've made before, that we can drink ten gallons of over the course of the summer and not get sick of. And we're going to make them until we get it right.
   
3. Take (even better) notes. I'm a big fan of brewing software. (We use Beer Alchemy. I'm partial to it because it's a well built Mac UI and it's dead simple to use despite having almost all the complexity you could want.) We already take detailed notes and monitor fermentation. But I'm talking about taking it to the next level and having a brewer's log detailed enough to track mash thickness, sparge rates, actual pH vs target pH, mash efficiency, evaporation, target vs actual attenuation, etc.
   There are a lot of little variables which don't lend themselves to tracking easily in the software but can (or at least I think they should) tell us something about the beers that turn out great vs. the ones that don't. (The fact that I'm spending a fair amount of time talking quality assurance with my buddy Gary who is damn close to opening up Panic Brewing just might have something to do with this.

So we'll see if it's made any difference by the end of the summer... It definitely can't hurt.

A Tale of Two Pales

These are actually the same beer. Same malt bill, same process other than a slightly longer mash on the darker one, different hops in the same quantity, and different carbonation levels. The left beer was hopped with Pacific Gem (13.2% alpha) and Australian Galaxy (13%) and the right was Columbus (13.9%) and Simcoe (13%). Never mind the shitty picture quality - you can still get the point.)

They're all small differences, but this is one of those one of those experiences that continues to blow my mind and preconceived notions about what matters in brewing.

I'm not sure where the dramatic difference stems from, but here are a few possibilities:

• There are a few episodes of Can You Brew It where Jamil talks about how particulate still in solution in the beer can actually make it appear lighter. 
• The actual oil levels in the hop combinations were different. I know that hops and yeast tend to do a little chemical dance at different points of fermentation, so it's possible that the beer on the right flocculated out better because of this.
• The dissolved volumes of CO2 were different (I carbonated the left and Jeremy did the right), which again could affect color
• One of the two beers (I didn't take great notes on the order we brewed them in) was mashed about 15 minutes longer than the other. I don't think that would have a significant impact, but in this case I can't rule it out.

So ultimately I don't really know how two beers with the same malt bill ended up looking so different, but it was an eye opening experience. 

Late (Aroma) Hop Addition Experiments

Jeremy and I brewed a clone of Epic Pale Ale (recipe from The Brewing Network's Can You Brew It) a few months ago. It was awesome. You can see the recipe here. It's not a standard pale ale.

The most noteworthy and interesting part of the beer was the different ways in which the brewer talked about using hops. (All US Cascade.) The recipe calls for two flame-out additions: a big flame-out addition held for a ten minute whirlpool, and then another big addition in another ten minute whirlpool. It sounded rather odd, but some of the recent reading I'd done emphasized the importance of getting the wort below 170F as quickly as possible to preserve hop aroma. Not to mention it put the whirlpool chiller I put together over the winter to good use.

The end result was awesome. Huge hop nose and a very distinct hop flavor.

Fast forward a few weeks. I found myself listening to a podcast with Stan Hieronymus in which he talked about the volatile compounds in hops. One of the more interesting nuggets of information was that ALL of the volatile aromatics are boiling off above 170f and some volatilise as low as 80f. (There is some far more complex chemistry going on here regarding the rate of volatilization and how other compounds in wort can "grab" onto the hop aromatics, but I don't really understand all of it.)

So with some additional credibility behind this lower temperature whirlpool technique, we decided to put it to the test. One of the brews we had slated for the summer was a pale ale from Brewing Classic Styles. So we tweaked the recipe a bit for this oddly timed addition and brewed two pale ales with the same malt bill but different character hops. One had Simcoe and Columbus, the other Galaxy and Pacific Gem. Both were bitterred with Horizon and each had a five minute addition, a flame-out addition whirlpooled for ten minutes, a 170F ten minute whirlpool addition and were finished with a dry hop addition.

Again - I am sure there is a lot of complicated chemistry at work, but there is absolutely something to this temperature stuff. These beers finished with massive hop aroma and flavor and definitely more so than we've gotten out of just dry hopping. I kept the Pacific batch and am really interested in brewing with both of these hop varieties again. There's a distinct melon / tropical fruit / berry / spice aroma to it

The only thing I'd go back and change is to tone down the bitterness a few IBU's. Rager calculated out in the thirties, bit that seems low for how much bitterness I pick up in the beer. If / when I re-brew I'll drop the horizon down to 14g.

Recipe(s):
5.126kg US 2 Row
340g Victory
340g Munich 10L
227g White Wheat

Mash at 152 for 60m.

27g Horizon @ 60

7g CTZ @ 5m
7g Simcoe @ 5m

7g CTZ @0m / 10m whirlpool
7g Simcoe @0m / 10m whirlpool

7g CTZ @170F / 10m whirpool
7g Simcoe @170F / 10m whirlpool

28g CTZ Dry Hop
28g Simcoe Dry Hop

(We used Galaxy and Pacific Gem in the same amounts.)

Citra IPA (Zombie Dust Inspired)

I love IPA's. They've been the beer I've stuck with in my journey to a deeper appreciation of all things beer. I've tried as many as I can get my hands on, made a pilgrimage to Delaware to try 60 minute at the source, and brewed many iterations of what never seems to be quite a perfect recipe.

Yesterday my brewing buddy (who I'll simply refer to as JP from here forward) did a ten gallon batch of an IPA with all Citra hops for the flavor and aroma additions. We're lucky enough to get Three Floyds Zombie Dust distributed here in Chicago, and they happen to carry it on tap at Merkle's (one of my favorite bars) whenever they can get their hands on it. It's a new release for Three Floyds, but it is pretty damn close to perfect. It's light copper in color, slightly hazy, and just reeks of that citrusy, resiny hop character that defines an American IPA. It drinks way too easily for something that comes in at 7%.

So, in the pursuit of finding a recipe I can keep coming back to and I based this recipe on Jamil's American IPA in brewing classic styles but substituted Citra for all of the late hop additions.

Citra IPA (10 Gallons)


US 2-Row Malt   25.50lb   (85.0%)
US Caramel 20L  2.00 lb   (6.7%)
Munich                 1.50 lb   (5.0%)
Melanoidin Malt   1.00 lb   (3.3%)


Warrior (17%)  43g @ 60m
Citra (11%) 46g @ 10m
Citra (11%) 62g @ 5m
Citra (11%) 46g @ 0m

We're fermenting at 64F and using White Labs' and Wyeast's California Ales in the two 5 gallon fermenters.






No results yet, but the wort was both sweet and bitter with a pretty hop-forward nose. Hopefully the aroma contribution from the Citra and the slight red tint we should get off of the Melanoidin malt get this beer closer to that IPA I've been lusting after...
