Rauchbier 2012

Any fellow brewers reading through my posts would quickly realize I tend to brew more ales than lagers. For those not familiar with the difference, ale yeast is a top-fermenting yeast that tends to work best at warmer temperatures, whereas lager yeast is a bottom-fermenting yeast that tends to work better at cooler temperatures. Ale yeast tend to contribute more flavor to the finished beer (e.g. esters) whereas lager yeast generally contribute less flavor resulting in a "cleaner" fermentation. Because of the cooler temperatures, lagers ferment slower than a typical ale so they can tie up your equipment a little longer. They also require bigger starters for a healthy clean fermentation, so they can cost a little more to make. That said, I do enjoy a lot of lager styles and particularly the one I'm brewing today, a Rauchbier.

Rauchbiers are similar to Marzen/Oktoberfest beers, so they tend to be malt focused. The major difference is Rauchbiers use smoked grains and the smokiness carries through to the finished product which can be good or bad depending on how much you like or dislike smoked foods.

I've brewed two Rauchbiers in the past, the first of which was fantastic but the second one suffered from a horrible case of chlorophenols. Chlorophenols can manifest themselves as band-aid-like flavors and aromas. They don't age out and humans are pretty good at detecting them even at very low levels. There can be various causes but chlorine in the brew water is a common one especially when paired with smoked grains which are phenolic by nature. If you plan to brew this style it can't be stressed enough, you need to treat your brew water to remove chlorine. There's nothing worse than finding out after 6+ weeks of nursing this thing along that you've ended up with band-aid beer. Carbon water filters, pre-boiling your brew water, and Campden tablets are a few ways to remove chlorine. It's pretty easy to prevent so just take the time to do it.

This recipe is loosely based on the Rauch Me Gently recipe from Brewing Classic Styles. I've adjusted the grain bill slightly to adjust for my efficiency (typically around 85%) as well as availability of grain from my LHBS. I was planning on using Weyermann Rauchmalt but the LHBS was out so I went with Cherry Wood Smoked Malt from Briess. In my experience this malt imparts a lot more smoke flavor than Weyermann's beechwood smoked malt, so I'm only using 1.8 pounds. I also cold-smoked 2.8 pounds of Weyermann Pilsner malt over hickory that I'll be using in this recipe.

4.2 # Weyermann Pilsner
1.8 # Briess Cherry Wood Smoked Malt
2.8 # Weyermann Pilsner Malt (home-smoked with hickory)
1.5 # Weyermann Munich II Malt
0.625 # Weyermann Cara Munich III Malt
0.2 # Weyermann Melanoidin Malt
1.7 oz Briess Black Patent Malt
1.5 oz Hallertau (60 minutes)
0.5 oz Hallertau (10 minutes)
(2 packs) Wyeast 2124 Bohemian Lager in a 1.57 liter starter
Wyeast Yeast Nutrient
Whirlfloc

Mash at 154F for 60 minutes. 90 Minute boil.

Ferment at 50F. This yeast is known to produce a bit of diacetyl, so it's best to perform a diacetyl rest after primary fermentation is complete to allow the yeast to clean up after themselves. To do this, raise the temperature from 50F to about 60F for 1-2 days. After the diacetyl rest, lower the temp to 40F for the lagering period. Allow it to lager for at least 4 weeks before bottling/serving.

Brewing Notes
No notable issues on this brew day. Color is a beautiful reddish amber. It started snowing around noon which made me really thankful for the ability to brew in the garage. The ground water temps have dropped to the high 40's, so I was able to chill the batch down to about 59F pretty quickly. A couple hours in my ferm chamber and the wort was down to pitching temp of 50F. I tasted a small sample and it's got a noticeable but smooth smokey character that seems very balanced with the malt profile. I can't wait for this one to be ready. Efficiency was about 83%. This seems to be about where I've settled in +/- 1%. That's with using a .045" gap on my grain mill.

Update 12/26/2012
I've got a couple inches of krausen this morning so things are progressing nicely. It's also worth mentioning, this brew may not quite fit the BJCP guidelines for a Classic Rauchbier since it uses a blend of cherry and hickory smoked malt rather than beechwood smoked malt. When smoking meat, different woods will create different flavors in the meat so I'd expect the same with smoked malt. Case in point, peat smoked malt should be used in very small quantities as it can result in a very harsh smokey character. On the other hand, some rauchbiers are made with up to 100% beechwood smoked malt. Despite the fact that this recipe doesn't use beechwood smoked malt, I think it will still be close enough to enter as a Classic Rauchbier in a BJCP-sanctioned event.

Update 1/3/2013
Fermentation seemed to be slowing so I checked the gravity and I was down to 1.017, so real close to finishing. I started ramping up the temp for the diacetyl rest.

Update 1/7/2013
I dialed the temp down to 40F the evening of 1/5/2013 to begin the lagering phase. A couple things surprised me with this beer. First was how quickly it fermented to terminal gravity. It just goes to show how important proper yeast pitching rates are, especially with lagers. I think this is the first time I have used two yeast packs and made a starter for a lager.

The second was the level of smokiness in this beer. The cherry smoked malt is smooth but intense. I originally bought 2.8 pounds for this recipe but scaled it back to 1.8 after eating some of it and realizing how smokey it was. The home-smoked hickory is more subtle by comparison and the combination of the two should add a level of complexity. This one is still in the fermenter but I'll probably transfer it to a keg soon for the remainder of the lagering period.

Update 2/9/2013
I put this one on tap for Superbowl Sunday and I think it turned out very well. It ended up having a much more subtle smoke character than I'd expected. It's noticeable but very smooth which may be why it seems more mellow/subtle. I'd guess it's at a level that would appeal to more drinkers than if the smoke character were more intense.

Dry Stout

Yesterday I brewed Jamil's Dry Stout recipe from Brewing Classic Styles. The picture above has nothing to do with the dry stout recipe...but it is what you might find if you google for a picture of dry stout...in this case something to keep a stout sportsman dry.

For this brew I used Simpsons Golden Promise, Briess Flaked Barley, and Briess Roasted Barley (300 SRM). I was planning on using a different variety of Roasted Barley (500 SRM) but the LHBS was all out. Per Jamil's instructions, the Roasted Barley was ground very fine, almost to a powder. Hops are East Kent Goldings and yeast is White Labs WLP004 with a 24 hour starter on the yeast stir plate.

Brewing notes: I was high on my starting gravity (1.048). I got a new false bottom for Christmas and my evaporation rate seemed a bit higher than normal, so I think both of these contributed to the higher gravity. I added about three quarts of sterilized water to the fermenter to bring the volume up a bit. This was the first brew session in the garage. It was still cold but much warmer than being outside, especially when it came time to clean up.

Update 1/16/2011: I kegged this one today. My CO2 tank also ran out and I noticed it was time for a hydro-test, so it will be about a week before my tank is refilled and ready to go. I prime most of my kegged beer anyway so I'm probably two weeks out before it's ready to drink.

Tasting notes:  This one is very good as well.  Since I had to use the lighter roasted barely, it was definitely not quite as dark as I would have liked but the flavors are great.  This is a keeper for sure, B+/A-

Chocolate Hazelnut Porter

This is round 2 of the Brewing Classic Styles recipes. For this one I tried scaling down to a half batch (2.5 gallons finished beer rather than 5). This ended up being kind of a pain because I designed my system for 5 gallon batches (e.g. the thermometer in my brew kettle was barely touching the wort with the half batch). So in the future I'll be sticking with full batches.

For this batch the domestic pale two-row is from Rahr and the Munich, Crystal 40, Crystal 80, Chocolate, and Black Patent malts are all from Briess. Hops are East Kent Goldings and Williamette. Per Jamil's recommendation, I'm omitting the late addition hops. Yeast is Wyeast 1056 California ale. The hazelnut extract is from Sunflower Market and is Flavorganics brand Organic Hazlenut Extract.

Brewing Notes: I ended up modifying my pick-up tube manifold. The original design got clogged with hops particles on the first run. This time I've added stainless steel hose braid to filter out hop particles. I'm using tea infuser balls to help keep hop particles contained.

We had a major snow storm last Saturday night, and a blizzard moved through last night. I was going to brew inside but my wife is busy preparing our Thanksgiving meal so I thought it best to brew outside and de-clutter the kitchen as much as possible. So there's a good 12 inches plus of snow on the ground and the temperature is a balmy 17 degrees. It's cold enough that I actually had some ice build up on the temperature probe wires. On the bright side, I should be able to chill 3 gallons down to pitching temperature in no time.

Update 1/2/2011: I just realized I never got around to publishing this post. I'm just getting around to bottling this one today. I ended up missing my starting gravity on this . This will likely be lower ABV than what Jamil intended. I went with 6ml of hazelnut extract. The hazelnut is there but it's subtle; very balanced with the dark chocolate. One note, the pick-up tube still partially clogged. Next time I'll try a stainless or copper scrubby and/or maybe hop bags.

P.S. 17 degrees is freaking cold for brewing. By the time I was wrapping things up the sun had started to go down and I was in the "shade". I'm not sure how cold it was but it was colder than 17. Before my next brew session, I tapped into my electrical so now I have the ability to brew in my garage. It's still cold, but it's warmer than outside.

No Short Measure - Ordinary Bitter

I recently bought the book Brewing Classic Styles by Jamil Zainasheff and John Palmer. The reason I bought it was Jamil has a reputation for brewing some great beer and I wanted to get a bit more familiar with classic styles and what differentiates each style. My goal is to brew most of these recipes at some point. I don't know that I'll brew every style, such as Light Lager because these sound too close to beers like Coors, Bud, etc. and I prefer a bit more flavor in my beer. I won't be posting the recipes here because I'm pretty sure that would violate copyright laws...plus this is a great book so if you don't have it go out an buy a copy.

The recipe I'm brewing today is titled No Short Measure and is an Ordinary Bitter.

Brewing Notes: I've added a carbon filter to my equipment list and this is the first brew I'm using it on. I also picked up a digital kitchen scale for my daughter's science fair project, but this will also come in handy for accurately measuring brewing ingredients. I'm in the middle of the mash right now, but if all goes well this will also be the first batch that I use the whirlpool chiller on. Malts used for this recipe are Briess Crystal 120, Briess Special Roast, and Maris Otter pale 2-row. Yeast is Wyeast 1968 London ESB Ale Yeast.
