In the Fermentor: Weizenbock

It's the middle of Winter and time to brew a nice Weizenbock. My take on the style leans toward a heavier Dunkelweizen in character, but doesn't contain a massive alcohol bump. However, it should still have a nice, dense liquid-bread effect on the palate.

Last year's Dunkelweiss had a very complex grain bill. In keeping with my 2013 resolution of doing more with less, this beer is much simpler. An even split of Dark Wheat and Munich Malt, plus a little Dehusked Carafa II for a hint of chocolate is it. I've broken the rules a bit, in that wheat makes up only 49% of my grist, rather than the German minimum of 50%. But what's 1% between friends?

Rounding things out, Opal hops provide mild bitterness, but should add little to no flavor. With a projected ABV of around 6.5%, the finished beer will be on the lighter end of the recommended Weizenbock ABV scale. Having Bock in a beer's name doesn't always have to equal an alcohol bomb.

I've not had the best of luck using a single-infusion mash with wheat malts. It works, but my efficiency has been low. This time, I've employed a multi-step mash with separate Protein, Beta and Alpha rests. It's a much more time consuming process, but the results were worth the effort.

I know that the type and amount of phenols you get from Weizen yeasts are rather tied to fermentation temps. Since I don't have precise temperature control like all the cool kids, I'm going to have to hope for the best. My apartment stays at a constant 68F (thank you hot-water heat that's not warm enough to handle dropping the thermostat at night). I also have a storage closet that is closer to 60F in the Winter. My plan is to do primary fermentation indoors and the secondary in the closet.

Here's the five-gallon recipe:

Grains:
6 lbs Weyermann Dark Wheat
6 lbs Gambrinus Munich Light
4 oz Weyermann Dehusked Carafa II

Hops:
0.8 oz Opal (6.3% a.a.): 60 min

Total Boil Time:
90 min

Yeast:
Safbrew WB-06

Mash Schedule:
Protein Rest: 121F for 20 min
Beta Rest: 146F for 30 min
Alpha Rest: 160F for 30 min
Mashout: 168F for 15 minutes

Original Gravity:
1.064
Estimated Final Gravity:
1.012

IBU: 20
SRM Color: 16

Fermentation Schedule:
2 Weeks Primary
1 Month Secondary
2 Weeks Bottle Conditioning

Cost: $15 per case
Commercial Equivalent: Weihenstephaner Vitus: $72 per case
Savings: $57

That savings number isn't a joke. There aren't that many Weizenbocks outside of the German ones that are easy to find. None of them are exactly bargains.

Out of the Bottle: Oak Aged La Petite Orange

I said in my previous post that I'd saved some of Northern Brewer's La Petite Orange kit to age with Sherry Infused Oak Cubes. The aged beer is ready to go, so let's see what the Oak and Sherry did. I've had more than a few Barrel Aged beers that were completely dominated by the wood and whatever alcohol (Rum, Bourbon, Sherry, etc) the barrel originally contained. In my beer, the oak and sherry are subtle. That's what I was shooting for, so I'm quite happy with that. The flavors and aromas from the original beer are still present. There's no point in revisiting them. What I really care about is the changes the wood made. Vanilla is the most significant contribution. There's also a very mild almond note at work. The Sherry really cuts through in the aroma. It provides an extra helping of dark fruits, plus a little more alcohol heat. The beer is definitely more wine-like than before. On a side note, I took my own advice and bumped the priming su

Out of the Bottle: Big Beers and a Haze

I'm doing a 4-for-1 with this installment, and will be bundling my finished beers going forward, rather than writing a blog for each. That should leave me space for more brewing oriented posts. This month, I've got beers I posted the recipes for back in November, December and January. First out of the gate is Enchanted Nightmare Imperial Stout. This beer is an amalgamation of extra grains and hops I had that were combined with some 2-Row and additional hops to create a 9.95% ABV Stout for the depths of Winter. So what if it wasn't actually ready until the Spring Equinox arrived? A beer like this can't be rushed. My beer pours nearly pitch black, and has nice ruby highlights. The head could stand a touch more staying power, but is appropriately dense. In the mouth, the body is a little lighter than I expected. The carbonation is very soft, and feels just about right for this beer style. When I bottled this beer, I was slightly worried that the whiskey and oak were a li

Kitchen Brewing Part 3: Sparge and Boil

The mash emerges from the oven. Now that we're finished with Part 1 and Part 2 of this series, it's time to Sparge. As you can see from the photo, the grains have absorbed a lot of liquid. In a traditional all-grain setup, your Mash Tun has a valve at the bottom to release the first running of Wort. The grains are then rinsed with the sparge water to extract any remaining sugars. My stove-top method doesn't afford such luxury, so a different method is called for. The grains have gained a little weight. There are a couple of choices at this point. One choice is to lift the grain bag out of Pot A and place it into the sparge water in Pot B to steep for 10-15 minutes or more. The other is to lift the grain bag up, put a colander under it and slowly pour the sparge water through the grains into the original pot. I prefer the former, because I get a better extraction rate from my grains. All that absorption means that the grains weigh a lot more than they did going i
