UPDATE 4/5/2014 – Beer placed 1st as a Vienna Lager in Category 3 European Amber Lagers at the 2014 First Round of the National Homebrew Competition (NYC Regional).

When it comes to brewing a particular style of beer, I am a serial philander. Rarely do I brew the same beer twice, and when I do it is typically with radical departures to the recipe. Of course, there are exceptions to this rule, and Vienna lager is one of them.

I’ve probably brewed four or five Vienna lagers since I began brewing in 2009. While most have been outstanding, and several have won pretty nice awards (Gold in the 2012 NHC first round, and 2nd Best of Show at the 2011 Best of the Bay), I seem to always be making tweaks to the recipe to correct minor details that I believe would lead to a better beer.

With this iteration, I’ve gone back to my favorite lager strain, White Labs WLP833 German Bock, which always seems to produce very malt-forward, diacetyl free lagers for me. Additionally, I’ve introduced a single step decoction into the recipe as a replacement for the touch of melanoiden malt that I generally throw into my non-decocted lagers. A small Hallertaurer addition with 10 minutes left in the boil gives the beer an almost imperceptible late hop character.

With winter coming, and the ground water cooling, it is the perfect time to brew lagers. My Blichmann Therminator plate chiller struggles with warm summer water, but drops the wort to pitching temperatures with ease during the cooler months. With a little extra time in my fermenation fridge, I am able to chill my wort to 44°F before pitching my yeast. Over the course of the lag phase, I let the temperature free rise to 48°F and then keep it there until the very end of fermentation when I complete a diacetyl rest. This requires a very large starter, but tends to create what I feel is a cleaner lager character.

Spawn of Duvel – Homebrew Tasting

Posted on November 17, 2013 by Nick Ladd

Judged as a BJCP Category 16B Belgian Pale Ale

Note: The Spawn of Duvel wasn’t really brewed to fit the Belgian Pale Ale category, but that is the closest category it fits into.

Aroma (6/12)
Very prominent banana ester that is reminiscent of artificially flavored banana candy or even under ripe green bananas. There is a bit of sharp alcohol that merges with this and reminds me that this beer is only 3 weeks old. The pear ester that I was hoping for is present, but in quantities that are barely perceptible. The is a very pleasant round pilsner malt aroma that is probably my favorite part about this beer. A herbal / earthy hop aroma is very low, but present.

Appearance (2/3)
The beer is a hazy rich gold color. The head is persistent and white. A couple weeks in the fridge should transform this into a much brighter beer.

Flavor (15/20)
The beer has a really nice slightly sweet pilsner malt character. The malt is a bit bread-like and features a very low, but complimentary toasty note on the finish. The banana ester and alcohol that was on the nose is much more subdued on the palate. Again, the hops are perceptible, but much lower in flavor than i had hoped or would have suspected based on the recipe formulation. There is a nice clean firm bitterness that doesn’t linger and perfectly balances the malt. At the finish there is a slight mineral note that is bit chalky.

Mouthfeel (3/5)
The beer has a medium mouth feel with a nice creamy texture. The carbonation is in line with most beer styles, but could used a bump to better fit the category. No alcohol heat or astringency.

Overall Impression (6/10)
This is a very enjoyable Belgian Pale Ale. It doesn’t have the malt complexity that the style guideline would call for which would likely hurt its scores in a beer competition. The main problem I see with the beer is that the banana ester is way too dominate. This muddies the familiar resemblance to Duvel that I was hoping for. In next iteration of this beer I need to figure out how to change my fermentation profile to better create the ester character I was striving for. Additionally, I would like to dry the beer out a bit more by mashing at a lower temperature.

Total: 32/50 (Very Good)

Sour Mashed Berliner Weisse with Brett Trois

Posted on November 11, 2013 by Nick Ladd

Reheating and recirculating the sour mash after 60 hours of sour-mashing.

Recirculating and reheating the mash after 60 hours of sour-mashing.

My first batch of Berliner Weisse left me confident that sour mashing is a viable option for creating brightly acidic sour beers in short order. I’ve had a number of wonderful sour mashed beers along with quite a few terrible ones. A lot of people proclaim that sour mashing is a bit of a crap shoot, but I believe with careful process control, you can utilize sour mashing with a high success rate. It seems that the key to success with sour mashing is creating an environment that favors the lactic acid production you’re looking for while discouraging the growth of other bacteria and yeast that can easily fowl your mash with pretty horrific off-flavors.

My primary concerns are creating an anaerobic (no oxygen) environment, maintaining temperatures above 105°F, and pre-acidifying the mash. An anaerobic environment is achieved by thoroughly flushing the fermenter with C02 gas and then sealing the lid. Temperatures are maintained by insulating the mash tun and periodic hot water additions. Pre-acidification is achieved through a healthy dose of acidulated malt at the end of the mash regiment. After a 60 hour sour mash, the liquid was very tart and clean. There was no pellicle, mold, or otherwise odd looking growths on the surface of the mash. At this point in the process, you’re looking for a bright clean acidity — more similar to yogurt (lactic) than vinegar (acetic). If your mash smells or tastes like rotten vegetables, baby diapers, vinegar, or other funky flavors, your mash likely went off. Boiling and subsequent fermentation may drive off some of these offensive aromas, but chances are pretty slim that they will be eliminated completely.

After sour-mashing I retrieved the soured wort and boiled it for 30 minutes to achieve a minor reduction in volume, kill any bacteria, and achieve a slight amount of bitterness. I cooled the wort and pitched Wyeast’s German Ale strain. I have heard antidotal evidence that low pH can adversely effect yeast fermentation. ~~I can offer my own contrary antidotal evidence — my low pH wort exhibited a very vigorous fermentation and attenuated well.~~

UPDATE 11/16/2013: After about 2 weeks in primary, I seem to be experiencing a pH related issue with this beer. Fermentation appeared extremely vigorous. It has however stopped at 1.010, which is most likely related to the beer’s low pH. At this point I am not comfortable bottling with a secondary Brett Trois strain. Instead, I have racked the beer to a secondary fermenter and pitched the Brett in an attempt to reach terminal gravity prior to packaging and bottle conditioning.

Wyeast describes the German Ale strain as a true top cropping yeast... I concur.

Double Dose IPA Review – Otter Creek / Lawson’s

Posted on November 5, 2013 by Nick Ladd

Last spring, I serendipitously had the chance to try Lawson’s Finest Double Sunshine while on a beer pilgrimage up to Vermont. Sitting on the sunny deck of The Reservoir in downtown Waterbury, the stars aligned — by pure luck, I happened to be seated for lunch at the very time that Double Sunshine was being tapped. In this case, the perfect atmosphere, company, and beer aligned to build a wonderful experience greatly exceeding the sum of its parts. The beer was absolutely fantastic and ever since I’ve been eager to try another of Lawson’s hoppy offerings.

Luckily Lawson’s Finest has teamed up with Otter Creek Brewing to produce a collaborative IPA called Double Dose. Thanks to Otter Creek’s distribution capabilities, a good amount of this beer made its way down to NYC and I was able to get a 4-pack.

Beer Tasting

Judged as a BJCP Category 14B American IPA.

Aroma (8/12)
Big in-your-face hops hit you as soon as your face nears the glass. Tangerine, pithy grapefruit zest, a very light hint of pine resin, and a substantial amount of ripe mango dominate. The intensity of the hops is quite high, but in many ways feel a bit muddled. There is just a hint of malt aroma. Some hot alcohol is apparent.

Appearance (2/3)
Very muddy and hazy. The beer paints a golden hue, which turns somewhat brown due to all the suspended solids. Head is bright white and persistent with tight creamy bubbles.

Flavor (13/20)
Citrus fruit dominates the flavor with a touch of pine sap. There is some very light crackery malt and maybe just a touch of sweet caramel. The bitterness is fairly moderate at first, but transforms into a fairly coarse and abrasive bite on the finish. The finish is further disturbed by a fairly substantial amount of hot alcohol.

Mouthfeel (4/5)
The beer is medium to medium-full bodied with a very distinct creaminess that is very reminiscent of Heady Topper to me. The beer finishes too full to fit well stylistically into the IPA category.

Overall Impression (7/10)
This is a nice example of an IPA that pushes, and likely exceeds the bounds of what most people would consider a standard IPA. I would be much more inclined to call this a double or imperial IPA. I enjoyed the hop intensity, but couldn’t help but think that the recipe could benefit from some hop varietal editing in order to allow individual flavors to pop on their own. Additionally, I found the amount of very apparent alcohol a bit overwhelming. I enjoyed this beer, but not nearly as much as my last Lawson’s experience.

Total: 34/50 (Very Good)

Spawn of the Duvel – Homebrew Recipe

Duvel. You sneaky little bastard. Crisp, refreshing, complex, yet not overbearing. Your austere dryness and pear-like ester melds with an ever-so-sweet pilsner malt background striking a balance that is tough to resist. I know it’s not a problem for you, but your 8.5% ABV is for me. I need a beer that possesses everything I love about Duvel, but doesn’t leave me spinning after a few.

This recipe intends to do just that. I’ve started this beer at 1.054 original gravity versus Duvel’s reported 1.069; mashing a bit higher and not including any simple sugars to decrease the wort’s fermentablity and create a mouth feel comparable to Duvel while having significantly less alcohol. Duvel attenuates in the 90%+ range helping it hit 8.5% ABV with a somewhat modest starting gravity. With the lower gravity of my beer, I’m hoping to achieve a similar balance by lowering the attenuation rate and finishing the beer at a more sessionable 5.5% ABV.

Duvel is reputed to contain only pilsner malt and simple sugar; up to 17% by some accounts. I’ve dropped the alcohol boosting simple sugar in favor of an all-malt grain bill, including a touch of character malts to bring some complexity to the wort composition. For hops, I’ve decided to go ahead and bump up the continental hop character found in Duvel by increasing the amount of late hops in the beer. This beer is by no means meant to clone Duvel, but will hopefully capture the spirit and attributes that make it such a great beer. We’ll know how successful I was when I taste the finished product in a few weeks.
