Brewing for Christmas 2014, Another Mild and A Smoked Brew

Christmas 2014 is upon us.  Every other year the Milliren clan closes in on the homestead of Mike and Martha Milliren.  All previous gatherings were in Chesterland, OH but with our folks having relocated to western North Carolina our future Christmases will be in Marion, NC.

Each time we gather, the brewthers and brewisters (Willie, Mark, Amber, and myself) try to bring homebrew offerings to sip by the fire.  Those that drive can bring more than those that fly and have to ship their brew.  Ashley and I have big plans to drive this year, so I have big plans to bring copious amounts of delectable (hopefully) homebrew.  I hope to arrive in Marion with 3 different 5-gallon kegs.  Brewing 10 gallon batches makes it easy to have beer on tap at home while saving enough for family gatherings.

The beers in order for me are:
Amber Lager (This is actually the beer I made for Oktoberfest 2014 and I had one keg left....decided to save it)
English Mild
Smoked Brown Porter

The English Mild was the same recipe from my first ever ten gallon batch.  If you'll recall from that recipe I ended up with an OG much higher than anticipated but the resulting brew was quite delicious.  I decided I would try to recreate that batch and ordered extra base grain to be sure to hit my target OG.  Well the base grain I ordered from an online retailer showed up with minimal crushing.  Long story short, I ended up with a lower OG than anticipated but was the exact OG from the original recipe I intended to brew from my first batch.  An interesting twist of fate.  Either way, fermentation went fine and I kegged that brew up last weekend.  I used the 1028 London Ale yeast and recycled that yeast into my next brew, a smoked brown porter.  Before I get to that recipe, here's a few pics from the Mild session.

Might be hard to see here but I rigged up a sparging system to pump hot water over my grains during the lautering process.

Collecting the run-off, good color.

Post-fermentation.  Going into the keg.

The smoked brown porter recipe was one I developed based off a few recipes and concepts I've read in JZ's 'Classic Recipe' book.  The primary recipe is supposed to be very similar to Sam Smith's Taddy Porter but I added rauch (smoked) malt to add some smoky complexity.  Here's the recipe I came up with:

14# Marris Otter (Had to supplement with 4# of locally sourced Marris Otter to get to target OG)
5# Rauch Malt
2# Brown Malt
2# Crystal 40L
1# Chocolate Malt
0.5# Pale Chocolate Malt

2.8oz of Fuggles (4.5%) at 60 minutes
0.3oz of EKG (5.7%) at 60 minutes (had it left over and thought, eh, I'll add it)
1.2oz of Fuggles (4.5%) at 10 minutes

Repitch of 1028 London Ale yeast, ferment at ~65F.

As I type this the smoked brown is winding down primary fermentation.  I will keg it in one week.  One thing to note is that throughout this entire process I've detected very little smoked character.  Not in the mash, not in the boil, not in the fermentation.  Further research shows that brewers experience varying levels of smokiness with rauch malt.  So I may have just gotten my grains from a lighter smoked batch...which is unfortunate.  Who knows, maybe the smoke will be there in the finished product.

Used the pump to transfer my strike water to the kettle (I'm trying to save my back).

Nice looking mash

Took my sparking a step further and secured the pumped water outlet to a copper piece that spans the mash tun.

Neat boil photo with hops

I hope all these brews turn out good and that my breathers and brewisters can enjoy them with me in a few more short weeks!

Zwickel tasting. Tasty. Zweet zweet zwickel. Tickle my zwickel?

Craziest/Longest Brewday Ever, 1/2BBL Oktoberfest

Who likes to spend ~12hrs on a beautiful Saturday decocting a 1/2BBL of all grain Oktoberfest?  Apparently me.  All that is left now is for the yeast to do their end of the deal. And as of this morning, about 18 hours after pitching, they are doing their end of the deal.

Oktoberfests, by tradition, are brewed in March.  So I'm a little late but I'm not expecting it to significantly impact the final product.

If you'll recall, I brewed a similar 5 gallon batch of Okto a little over two years ago.  With wedding activities last March (2013) I was unable to brew a batch and I feel my 2013 Okto party suffered because of it.  I had the time this year but it had to wait until this weekend.  I like my recipe so much that I did my best to maintain the same grist ratios and hop ratios, just scaled up.  One thing to note is that I'm not as obsessed over water chemistry right now.  I recently installed an 'under-the-sink' water filtration unit in our kitchen and the city water tastes pretty good.  This is my third brew with the water and each time my pH during mash is OK so I'm just letting it ride.  No extra brewing salts or dilutions with distilled water.  Here's the recipe:

10# Weyermann German Pils (1.6L)
8# Weyermann Munich (5-7L)
8# Weyermann Vienna (3.5L)
1.25# Crystal 40L
1.25# Crystal 60L
1.0# Weyermann Munich Dark (8-10L)

Dough in to roughly 148F first Sacc rest for 30 minutes. Pull 15 qts of thick decoction and decoct (I don't think the details are necessary....comment if you disagree).  Return to main mash to raise temp to 158F for 30 minutes.  Pull roughly 12 qts (I seriously eyeballed this amount so I may be way off) of thin decoction and boil.  Return to mash to raise to mash-out temp of 170F.  Sparge.

90 minute boil
2.4oz of 6.9%AA Tradition (mainly Hallertau I think) at 60 minutes
0.8oz of 6.9%AA Tradition at 20 minutes

Target OG of 1.055 on roughly 16 gallons (I hit the target!)

Chill to 56F (took about 30 minutes to get the 16 gallons to around 80F on ground water and then another 30 minutes using an ice bath pump to get down to 56F...that was as good as it was going to get on this fine day).

Hit with O2 and WY2487 Hella Bock yeast (repitch off the Zwickel).

I will ferment this at around 52F for 2 or 3 weeks and then keg and lager at 33F for 6 weeks before carbonating and storing at 45F, for the rest of summer, until Oktoberfest 2014 arrives.

Pictures now:

To brew a 1/2BBL I had to make a couple upgrades.  Added another Blichmann burner (these burners are awesome), and the ~22 gallon frankenstein kettle on the right.  My usual 15 gallon boil kettle (on left) became my mash tun.

The original Zwillingsbrudder copper manifold is always ready for a mash.  Here I've used a piece of food grade silicone hose to connect the manifold to a stainless barb connected to the ball valve on the kettle.

Brew shoes. White Socks.  The Dude abides.

Dough-in.  My favorite picture from the day.

So the frankenstein kettle had a hairline crack (probably not visible in the photo but its at the bottom corner of the spout) on one of the welds and it had a slow leak.  I tried  to flow some solder into the joint but it wouldn't take.  Had to use liquid nails on the outside to temporarily seal the leak.  Hopefully not to the detriment of the beer.

First Sacc Rest.  About to pull a the first decoction.

THICK decoction about to boil.

I was grateful for my beautiful wife's help on this hectic brew day.  She was a huge help.  Here she is stirring that mash!

Sparging.  I connected the ball valves on each kettle through a march pump and another ball valve (outlet side).   This allowed me to restrict the output flow of the pump and fill the boil kettle at roughly 2qts/min.  Worked great.

19 gallons on the way to a boil.

Spent grain.  Extra spent from the decoction.  85% brewhouse efficiency baby!

Towards the end of boil, copper coil ready for work.

Hit my gravity.  I like the color too. It might be a little more pale than my last Oktoberfest.  Whatevs.  In case you care, it's because the Munich Malt on this batch was Weyermann brand and roughly 6L where the munich from my last batch was Briess and was 10L.

Chillaxin while the fermentors fill.

Zweet Zweet Zwickel

One year ago I was in St. Louis with good friends and family tearing up the town for my bachelor party.  One of the highlights of the trip was a visit to Urban Chestnut Brewing Company.  A relatively new brewery on the St. Louis scene, they had an amazing line-up of old school european ales and lagers along with more popular american craft brews.  One of the beers I enjoyed most was their Zwickel.  Zwickel can be paralleled to (if not 'also known as') German kellerbier.  It's young lager.  Hazy, malty, yeast turbid, raunchy, young.  All kinds of different and delicious flavors that are typically muted when a lager goes through a traditional lagering period.  These beers are meant to be fresh and funky.  I loved it.

I want to brew another batch of Muhleisen All Grain Double Decocted Oktoberfest again this year, but in order to do so I need loads of fresh healthy lager yeast.  I couldn't think of a better way to build up a yeast culture than with a lower gravity Zwickel-style wort.  Working off the ingredients provided by Urban Chestnut and also off the recipe from brewing legend Michael Dawson (linked here), I came up with this recipe (for 10 gallons):

16# German Pils
2# German Carahell
1# German Carafoam

128F for 20 minutes, 149F for 30 minutes, 158F for 30 minutes, 168F for 10 minutes.

1.5oz of 6.9%AA Tradition hop at 60 minutes (basically Hallertau)
0.5oz of 6.9%AA Tradition hop at 15 minutes

Target OG: 1.048
Target IBU: 20

My mash got all screwed up so my schedule was really like 132F for 20 minutes, 151 for 40 minutes, 154F for 20 minutes, straight to sparging.  We will see what the result of this debacle is.  Hopefully it doesn't cause another 'Debockle'.

For this batch I had to make a 1 gallon starter using 4 smack packs of WY2487 Hella-Bock yeast.  I hit my gravity numbers and with the ground water still cold I was able to chill to 60F in 15 minutes with my JZ style immersion chiller.  I could have gone colder but I wanted to pitch the yeast starter a little warm and once activity has taken off I will get it into a 50-55F fridge for primary.

This brew will not be lagered.  In two weeks I'll keg it and rinse the yeast cake for the yeast I need for my Oktoberfest.  As with all my brews, I can't wait to see how this one turns out!

I bought a new 'large-face' thermometer for my boil kettle.  Just cuz.

Mash.

First runnings, you can see how short the thermometer stub is.  Also the color of the wort.  Also that awesome mash paddle.

Another shot to see the color in hose.

Sparging.

This is my new 'graduated cylinder' for taking gravity measurements.   My old tube gave out on me so I had to think on my feet.  Footed pilsener glass just seemed fitting and it worked well.  I like the color.

BOIL.  I collected a little too much pre-boil but that's because I got a  better efficiency than expected.

Hops.  Smellin right.

I really like this Spiedel fermentor.  Makes life very easy with these 10 gallon batches I've been doing.  I also bought an oxygenation system to step up my game.  The red can is a disposable canister of O2 from Home depot ($10, should provide oxygen for at least 5 batches).  I got the regulators, hosing, and stainless oxygenation stone (2 micron) from more beer.  We will see what results it yields.

In two weeks I will have a crazy Oktoberfest brew day.  Hopefully it goes well.  In about 4 weeks I'll be tapping into some young and hazy Zweet Zweet Zwickel.

Back to Brewing - 10 Gallons of American IPA

It has been a long winter.  The cold that shook the south put me in a serious hibernation mode.  It was all we could do to get out of a warm bed every morning, get to work, get home, get dinner, get cozy, get in bed, repeat.  The last couple of months I've done very little in the way of anything extracurricular.  I needed a break from brewing and frigid temps only further encouraged me.

Well it's started warming up here again and today was a picturesque day to brew a batch of beer.  Temps swelled into the upper 60s while the ground temperature (and ground water temperature) is still recovering from winter and in the 40s (ground water temp coming out of our faucet is almost exactly 50F).  There were 8 ounces of various hops residing in my freezer that I thought would go towards a delicious IPA.  Dry yeast was an easy way to get back into the swing of things and US-05 is always a good yeast.  All I needed was water and grains.

I've read all kinds of good things about floor malted Marris Otter.  I know it's not an American malt, but it gets rave reviews in all beer styles, including IPAs.  Here is how the scene unfolded:

24# Floor Malted Marris Otter
1# Carapils

Mash at 151F for 60min
Raise to 170F for 15min

Preboil OG on 13 gallons (only 1.046...I missed my goal so added some DME to bump it up to 1.051)

2 oz. of Northern Brewer (10.6%AA) at 60 min
2 oz. of Chinook (11.8% AA) at 15 min
1 oz. of Willamette (4.7% AA) & 1.3 oz. of Simcoe (12.2% AA) at 5 min
1.7 oz. of Simcoe (12.2% AA) at 0 min

The beauty of this time of year is ground water temperature.  I use an immersion chiller with a recirc pump to push my hot wort across my cold coil.  I was able to chill this 10 gallon batch to 60F in 20 minutes. That's some serious chillin, Batman!

A nice addition to my brewhouse is a 16 gallon plastic fermentor I grabbed off of MoreBeer.  It's german made and seemingly of very good quality.  The plastic makes it easy to move 10 gallons around, and the wide lid makes it easy to clean.  I've read very good reviews on these fermentors, so hopefully it serves me well.

Picture time!

The mash.  My 10 gallon batches really push the limits of my 12 gallon mash tun.

Hop Spider in action.

The fermentor.  I'm excited about this addition to the brewhouse.

One of my favorite ways to end a brew day.

I plan to dry hop this batch of brew with another 2 oz. of Simcoe hops.  Hopefully I will be kegging this batch up in about 2 weeks and tasting within a month.

My old hop stash is all gone.  My next couple of brews will be a little funkier (Belgian Wit?, Bavarian Hefeweisen?).

I know I'm bad about keeping my blog up-to-date.  But between a renewed passion for brewing, and a lot of excitement in daily life in Fayetteville, I hope to be writing again soon.

To Build a Tube Pre-Amplifier

Those who know me, know I've been known to dabble in high-end audio equipment.  It all started when my old man entrusted me with a system he had purchased/built in the 1970s.  He had built the speaker enclosures to pair to a Pioneer receiver and BIC turntable.  While the definition of what is truly 'high-end' can be debated, his system was nothing to blink at when he had his records spinning.  That system has since been adopted by my tchwin, Mark.  In it's stead I bought a smaller system better suited for integration to our TV and Blu-ray player.  I won't go into the details here but it is also a very good sounding system.  I simply enjoy good sounding music.  But the 'tinkerer' in me won't let me just sit idly by and listen.  I have to wonder, 'What makes good audio?'.  So I read about these sorts of things when the mood strikes and when I have the chance to tinker with equipment, I do.

I stumbled upon a company called, 'Bottlehead', that deals all things DIY audio kits.  They have a very well regarded tube pre-amp kit called, 'The Quickie'.  It's $99 of components that, with a solid list of instructions, you are left to assemble/solder.  I decided to jump in and try my hand at building me one of these tube pre-amps.  It all went pretty smoothly and was completely built in about 4 hours.

This is the back of the board where all the hardware mounts and the wiring connections are made.

What good is a project without a beer?  I've been enjoying smoked beers lately.

All wired up.  Resistors, capacitors, potentiometers, tube sockets, etc.

This is the board 'right-side-up' with the tubes (cylindrical glass things on the left and right of the middle knobs) installed.  The board is sitting in a wooden base that I also bought from Bottlehead for $40.

Ashley snapped a picture of me in action with my soldering iron.  Notice the glasses.  Safety first, people!

So what do you do with a 'pre-amp'?  Well most audio receivers have a pre-amp section and a power-amp section to take line-level audio and amplify the signal enough to drive loudspeakers.  My Outlaw RR-2150 receiver is one like this.  But there are jumpers at the rear of the unit that connect the pre-amp section to the power amp section.  When I removed these jumpers I was able to run my CD player (Blu-ray player) through my hand-built pre-amp and then run cables from the pre-amp into the 'Main-In' (i.e. power-amp input) on my Outlaw.  The results were pleasing.

In side-by-side comparison with the pre-amp section in my Outlaw using a CD track of Wilco's 'Impossible Germany' as my reference I was able to see just how good this little 100 dollar pre-amp is.  The truth is, I struggled to differentiate between the two set-ups.  If anything, the tube pre-amp was a little more warm and maybe slightly more 'fuzzy' than the Outlaw.  But 'Impossible Germany' was impossibly delicious every time I listened.

All in all this was a great little 'tinkering' project for me.  I learned a lot and got to practice soldering. All said and done, it was $150 very well spent.

If any of you decide to swing past the house I'll be more than happy to give you a listen.
