#21 Oaked Arrogant Bastard Clone - Tasting

Recipe     -     Brewday     -     Tasting

ABV: 7.8%
IBU: 94
Serving Temp: 38F
Carbonation: 2.8 vol
Grade: B+

It took a full month from brewday before this beer was really ready to drink, but at that point it magically turned awesome.  It started out thick, sweet and boozy, but as the flavors evolved and melded, the bitterness--both from the hops and the oak tannins--awoke and brought the beer back into line.

I really love the color of this beer.  It's a brilliant deep dark red-brown, much like the Irish red I did for St Patrick's day, with a light beige head.  A lot of light beige head.  I need to re-balance my tap lines because every beer is coming out half foam, but that's not the beer's fault.


The aroma I'm not as in love with, and that is the beer's fault.  It's got a rough edge to it, similar to what I find in Belgian beers (especially saisons and mixed-fermentation brett beers), or maybe soggy wood.  It doesn't really detract from the beer if you don't sit there and sniff at it, but an enticing aroma is a great way to score early points with the drinker.

The flavor more than makes up for it. I feel like this is a malt forward beer, with an intense, deep malty-sweetness at it's heart and all the alcohol you would expect from such a strong beer.  However, the hop bitterness is certainly up to the task of restoring balance, and last night I even had this beer described as particularly hoppy.  And if there wasn't enough flavor happening already, there's also the oak doing its thing in the background.  It's not especially bold, but it gives a bit of earthiness that complements the Chinook hops particularly well while melding nicely with the rich malt.

I have to say that since this beer turned the corner I'm really loving it.  There was nothing overtly wrong with this beer, which is step one, but there is also a level of balance that is hard to achieve.  Stone's recipe is a shining example of how finely balancing a few ingredients can achieve a superior product to more extravagant concoctions.


Update 6/12/14:  Last night I got to taste this beer head to head against the real Arrogant Bastard and Oaked Arrogant Bastard.  Overall I'm surprised how close of a match it is.  The color and aroma of all three are identical, the original AB had more hop flavor, but the vanillin in the oaked version seemed to smooth it out, bringing it much closer to my clone.  Mine is still sweeter and boozier than the oaked beer which was a bummer; the Stone brew has a nice clean dry finish that I think we all preferred, but the bitterness lingers for a few seconds after the rest of the taste has dissipated, which some like (me) and others don't.  I think switching to oak chips with their rougher character would go a long way to increasing the bitterness, but a little more bittering hops wouldn't be out of place.  At 90 IBU (est.), there isn't a whole lot more room for iso-alpha acids, so an increase would run little risk of over-bittering.  All-in-all, I'm happy with how this came out and would highly recommend this recipe as both an Oaked Arrogant Bastard clone and just a great beer.

Grading System

I've been making some changes to the tasting notes, pulling important stats to the top like alcohol content and recommended serving temperature, which I hope will make the blog easier to use.  But one of these additions, the new grading system, might need a few words of explanation.

Everyone will have their own opinions of a beer and enjoy each one in different ways, so it's not meaningful to try to assign a beer an absolute quantitative value.  However I think it will can be interesting to compare how a beer turned out relative to the expectations or goals for that brew.  I'll spend a good deal of time talking about that in the review, but the letter grade will give a quick summary for those of you unwilling to wade through the volumes I compose.  Please don't take this as a measure of how much I think you should like the beer.

#22 Oatmeal Pale Ale - Brewday

Recipe     -     Brewday     -     Tasting

Yeast Starter 5/18/14:
Yeast character won't be a focal point of this beer, so I'm reusing the Whitbread yeast I saved from the American wheat I brewed about a month ago.  I harvested the yeast from that beer, used some on the Arrogant Bastard, and saved the rest in the refrigerator.  I was a little worried about the yeast health after sitting for a month, so I prepped a .3 gal starter with 1/4 tsp of yeast nutrient.

When I went to open the jar of yeast, it exploded all over my mom's kitchen.  Apparently the yeast--who I thought were done fermenting and would sleep peacefully at 40F--had scavenged residual sugars from the small bit of wort left in the jar and produced enough carbon dioxide to turn the glass jug into an IED.  Apparently that's why they advise you to vent stored yeast the first couple weeks of storage.  (EDIT 5/27/14: Apparently I'm not the only one to make this mistake.  Check out this article from this month's issue of BYO.)


Brewday 5/25/14:
This was a good brewday; friends John, Melanie, Dana and Pat, all came up to help out with the brew and see the process which was a lot of fun.  It helps to have an extra set of hands (or four) and some company for the 7-hour undertaking.  I have a hard time multitasking--making the day entertaining while still juggling all the balls in the air for the brew itself--but I hope everybody had fun.


For this beer, we tried out a new mash process.  I've been doing brew-in-a-bag since I moved to all-grain, but this time we finally broke in the mash tun.  I've had the cooler with a PVC manifold since I bought my brewing equipment--an entire HERMS system in fact--but I had been waiting for the guy who sold me everything to help get it patched up and all the hoses and pumps in place.  I haven't seen him since.  I finally gave up on that and just went with the simplified single infusion mash (4 gal) with a two-stage batch sparge (2.5 gal each).  Everything went surprisingly smoothly for a new process: no major mistakes, nailed the mash temperature (151F) and pH (5.45), no stuck sparge despite the high percentage of oats, and got a nice bump in efficiency (55% to 65%).

After the (surprisingly mild) hot break, the boil developed an oily sheen.  There were no bittering hops in this recipe, so it was something from the grain, not hop oils.  I've read that oats can cause head retention issues because of the high lipid content, so I'm thinking that was it.  As the center of the kettle continued to bubble, the oils settled into a thin film around the edges and formed a scummy residue with the break proteins still floating on the surface.  Now there is always scum on the top of the brew kettle, and I've heard removing it can improve flavor and clarity, but also that you can remove head-forming proteins.  I don't know the best way to handle it, but this time I went ahead and skimmed what I could.

Another change in this batch was the switch from Irish moss to Whirlfloc tablets and it made a noticeable difference.  I wish I had snapped a picture after the boil, because the protein coagulation during chilling was much more dramatic, with big coral-formations of denatured enzymes looming underneath the golden wort.  I was worried the high percentage of oats might make for a cloudy beer, but this was certainly the clearest wort I've had.  Unfortunately the false bottom didn't strain as much of this out as I hoped, so a large percentage of the trub wound up in the fermenter.


Fermentation:
Wort chilled to 60F, 30 sec O2, yeast pitched from decanted starter, placed in fridge set to 66F.

1 Day: The heater failed to come on, so the beer temperature was stuck around 62F.  I tightened the bulb and bumped the temperature to 68F.  It looks like the yeast got a healthy start regardless and are swirling vigorously.

6 Days:  Added dry hops, 2 oz Columbus and 2 oz Cascade.  It was two much hops to get them all submerged, but hopefully over the next few days they'll all settle into the beer.

14 Days:  This beer is just a mess of hops.  4 oz is too much to do at one time, next time I do something hoppy I think I'll do a two-stage dry hop a la Pliny the Elder.  Gravity has dropped all the way to 1.009--more than I expected--for 81% apparent attenuation, exactly the same as the Arrogant Bastard clone with the same yeast.  The hops are really popping right now as expected.  Can't wait to try this carbed.

#22 Oatmeal Pale Ale - Recipe

Recipe     -     Brewday     -     Tasting

Many breweries have oatmeal stouts, but few use oats for anything else.  About two years ago I was at Elysian Brewing in Capitol Hill and saw they had an oat IPA on tap.  Now this shouldn't really be that surprising, Elysian is always cooking up odd recipes, and like everyone else in Seattle, is obsessed with IPA, so this was fairly classic them.  The beer had the hop flavor of an IPA, but with a smooth, creamy mouthfeel that hid the intense bitterness normally associated with the style.  I really enjoyed it, but have never seen it since.

Several months later I was at a grocery store looking for something to enjoy on a sunny Friday afternoon and came across Fort George Sunrise Oatmeal Pale Ale.  I really enjoyed the last few beers I had from them (if you haven't had Vortex IPA or BB Cavatica Stoutyou've made a huge mistake), and remembering the Elysian version I decided to give it a shot.  I was disappointed.  Maybe the cans were old, but instead of smooth and flavorful it was bland and particularly bitter.

Well now it's my turn to see what I can brew with the concept.  Personally I think oats are one of the most boring ingredients you can use; everybody knows how tasteless oatmeal is on its own, but when you mix it in a beer it seems to suck all the flavor out.  That's great in a breakfast stout where it can take the edge off an overdose of coffee, or in the Elysian beer where it tempers the bitterness of the hops, but it's a double edged sword as Fort George showed.  That made this recipe a fun mental exercise at least, hopefully with a fun end product too.

For my recipe, I'm going to start with an oat heavy grist, then hop burst with big doses of Cascade and Columbus hops.  I've gone round and round on the varieties--Chinook to Simcoe to Cascade to Columbus to now a 50/50 split--but I think I've finally found what I'm looking for (unlike U2).  The Columbus has a big, sticky, mouth-filling flavor that should compliment the oats nicely, with just enough roughness to test how well the oats smooth them out, then the Cascade adds a bit of citrus to brighten things up and round out the classic American hop character.

It all sounds so good in my head, but we'll have to wait and see if I actually know what I'm talking about.
