Czech Premium Pale Lager 2018

>> Sunday, June 10, 2018

Today I'm brewing my third Czech Premium Pale Lager. The first attempt at this style won a gold medal while the second didn't fare as well.  Comments on the second version indicated the judges thought it had a brett infection. Given how many sour/wild beers I brew, this is entirely possible and I thought I was also able to taste a little funk, especially after a few months in the bottle. I don't believe that brett and bugs are the bogeyman that a lot of people make them out to be, but it goes to show that you need to be careful. In my case, I believe it was picked up in my counter-pressure filler, so I've changed my sanitation procedure by incorporating a pasteurization step every time I use it (140F recirculation while submerged in the same 140F water for about 20 min; heated by my sous vide cooker).

So back to the Czech Pils/Bohemian Pils/Czech Premium Pale Lager. I'm gaining an appreciation for lighter, more delicately flavored beers. I tend to gravitate towards big bold flavors in beer (and food) but there's definitely a time and place for easy drinking beers. The key to brewing this style is very soft water, so I start with distilled water and use minimal salt additions.. Here's the recipe as I'm brewing it today:

8.0# 11 oz Weyermann Floor Malted Bohemian Pilsner
9 oz Briess Carapils
34g Czech Saaz 4% AA (60 min)
41g Czech Saaz 4% AA (30 min)
20.5g Czech Saaz 4% AA (10 min)
20.5g Czech Saaz 4% AA (0 min)
Imperial Yeast L28 Urkel
0.5 Whirlfloc
0.5t Yeast Nutrient

Mash at 154F for 90 mins, 90 minute boil, chill to 44F, aerate well and pitch yeast. Raise temp to 50F over 48 hours. Raise temps to 64F for the diacetyl rest. Cold crash after a couple days.

Water Recipe
10 gallons distilled water
0.55g Epsom Salt
0.33g Calcium Chloride
0.44g Baking Soda
0.44g Chalk

Brewing Notes
No issues in this brew session. I was working on some other projects at the same time, including putting up a trellis and getting started on my first attempt at homemade pastrami. I had to run to the store at one point and had to enlist my son to do the 30 minute addition. OG came in at 13.9P (1.055).

Update 8/5/2018
This beer went in the keg today along with some gelatine for fining.

Update 9/25/2018
So...this beer has a little bit of a problem. It tastes great right off the tap, but once it starts to warm up it's apparent there's some acetaldehyde. It comes across much more in the aroma than the flavor, but regardless, it's not good.

As for the cause, it's often related to one of three things:

  1. Poor yeast health - Acetaldehyde is naturally produced during fermentation. Towards the end of fermentation, the yeast converts it to ethanol. If yeast health is compromised, they may not be able to finish converting it.
  2. Transferring too soon - Even if the yeast is healthy, if you pull the beer off the yeast cake too early, it can result in acetaldehyde.
  3. Oxygen exposure - I've read that O2 exposure post-fermentation can result in ethanol being converted back to acetaldehyde.
In this case, I suspect that oxygen exposure is probably the culprit.

Berliner 2018

>> Friday, June 08, 2018

Just a quick post today. I'm brewing another Berliner, this time kettle-soured with GoodBelly SuperShots, then primary fermentation with Wyeast 3191Berliner Weisse Blend. This is by far my favorite blend for BW due to combination of the sach, brett, and lactobacillus in the blend. As I indicated, I'll be kettle-souring, so the bulk of the acid production will happen pre-boil, before the blend is pitched.

The process is mash, collect ~7 gallons, pre-acidify pH to 4.5 or slightly less, raise to 180F for about 15 minutes, chill to ~100F, transfer to my 1/4bbl Sanke and pitch lactobacillus. Then let it ride until pH gets where you want it, 3.2 - 3.4 in my case. Next, boil as normal, chill, ferment. Here is the recipe as i brewed it.

4.0 # Avangard German Pale Malt
3.5# Weyermann Pale Wheat Malt
Rice Hulls, as needed (usually about 0.5#)
1.0 oz Aged Debittered Hops (60 min, 0.0 IBUs)
0.5 oz Sterling (in Whirlpool when temps <170F, 0.0 IBUs)
GoodBelly SuperShot - 1 or 2, depending on freshness
Wyeast 3191 Berliner Weisse Blend

Mash at 150F for 90 minutes, kettle sour at room temp, 90 minute boil, no aeration, ferment at room temp.

Brewing Notes
Day 1 - Mash and Starting Kettle Souring - 6/4/2018
No issues. Wort was acidified to a pH of 4.42 using phosphoric acid. I was doing other things around the house in addition to brewing, so I think I held the temp at 180F for about 45 minutes. That's not a problem though as the purpose of this step is to pasteurize. Wort was chilled to just below 100F and GoodBelly was pitched. I did use two GoodBelly  SuperShots because they were not quite as fresh and I figured some of the cells had probably died off.

Day 2 - Boil - 6/8/2018
The pre-boil pH dropped down to 3.20. This is lower than I've ever gotten without acidifying to <4.5 for kettle souring. The end of boil pH is 3.27, probably due to the addition of hops, yeast nutrient, and/or Whirlfloc. No issues during the boil. Gravity came in exactly at 11P (1.043).

Update 6/9/2018
I'm seeing signs of active fermentation this morning with about 1 /2" of krausen. That's a good sign because this blend can be a slow starter and the smack pack didn't swell as much as most other strains.

Lichtenhainer 2017

>> Friday, May 25, 2018

Today I'm getting started on beer based on an unusual historical style, a Lichtenhainer. What makes this style unusual is it's both a smoked beer and a sour beer, along the lines of a smoked Berliner Weisse. I'm a huge fan of both smoked and sour beers, but I have to admit that a sour smoked beer sounds a little weird even to me. Regardless, I'm doing one.

At one point all beers had a smokey character due to the way that malt was produced; malt wasn't originally isolated from the fuel (wood) that was used for drying and kilning. For my interpretation of the style, I smoked all the malt using my malt smoking setup. For this version, I decided to use pecan wood for smoking and I'll be doing a kettle sour method. So this beer is more along the lines of being inspired by the historical style rather than being a true example of the style. The recipe I'm using is based on Mark Schoppe's award-winning NHC recipes. My interpretation is likely to turn out more sour and more smokey than Mark's.

I'll be doing a split batch (after primary) where half will get chipotle peppers added in secondary. As with other smoked beers, it's extremely important to eliminate chlorine from your brew water. If you don't, you're almost guaranteed to have chlorophenol problems. Here's the recipe as I'm making it today.

Pecan Cold-smoked Malts
     4.125 # Avangard German Pale Malt
     4.125 # Weyermann Pale Wheat Malt
14g Aged hops (60 mins)
GoodBelly SuperShot for kettle-souring
Wyeast 2565 Kölsch after kettle-souring
Whirlfloc
Yeast nutrient

Mash at 150F, transfer to boil kettle and raise temps to 175F for 15 minutes to pasteurize. Chill to 100F before pitching GoodBelly and sour to a target pH of 3.4-ish. After target pH is reached, proceed with boil, 90 minutes. Ferment at 63F. When primary is complete, add 1 rehydrated chipotle pepper per gallon.

Brewing Notes
Day 1 - Things went fairly smooth with no issues. I ended up using phosphoric acid to reduce the pH to about 4.48 before pitching the lactobacillus. I haven't really done that before, but it's pretty standard for kettle souring. I sampled the wort and the smoke level seems complimentary and not overpowering. That's a good sign because it can tend to come out more after fermentation and carbonation.

Day 2 - I proceeded with the boil today (5/28), no issues. The post-boil pH came in at 3.37. OG is 12.2P (1.048).


Update 7/7/2018
Half got kegged today, and the other half went on three chipotle peppers (two large, one small), rehydrated in boiling RO water.


Update 8/5/2018
I bottled the Chipotle half today. I tried the straight half and it had a horrible green apple cider character. I may have rushed it through primary, meaning the yeast didn't have time to clean up acetaldehyde from primary fermentation. I didn't notice the issue in the Chipotle half... possibly because of the extended aging on the peppers. Another possible problem, I cold crashed this batch then raised the temp back up because of another beer I had in the ferm chamber. Then I cold crashed again. This may have exposed it to too much oxygen. I ended up dumping the straight half; it was nothing I'd ever want to drink.

Sous Vide Details and Tri Tip

One of my nephews is a chef and used to work at Haven Gastropub in Orange, CA. While there, he came up with a recipe for pork belly that was absolutely amazing. He described a process called sous vide, where they would cook the pork belly overnight in a water bath. Then before serving, the pork belly would be briefly seared in a hot pan, just enough to add some a thin layer of bacon-like crispness to the pork belly. It was served on a bed of greens and the low and slow cooking process resulted in a delicious fork tender dish that practically melted in your mouth.

Sous vide cooking is pretty well known now, but when I first tried my nephew's dish, it was a process I'd never heard of. I looked into it a bit and saw that there were several sous vide cookers on the market but I was hesitant to lay out the cash for one. They're pretty basic and usually consist of a heating element controlled by an electronic thermostat/switch that receives a signal from a temp probe. There's also some means for circulating water to ensure even temperatures throughout the water bath. It doesn't take a genius to realize this is very similar to my HERMS setup and how I use it for mashing grain. So I decided to do a trial sous vide cook using my brew system and some beef tenderloin steaks. The results were amazing and not too long after that, I bought an Anova Precision Cooker. Now you may ask, why did I buy one when my brew system worked so well? Well the brew system was a bit of overkill for what's needed (too much water, too much cleanup, etc.) and sometimes certain spices can permeate the plastic bags used for sous vide. I definitely didn't want any beefy off flavors in my beers, so I decided to buy a dedicated unit.

The process is pretty simple so I won't go into a ton of detail. Plus there is a  lot of info on the Internet, so there's no need to regurgitate what's already out there. Basically, you season your food, seal it in a bag, then cook it in the bag in a water bath at a given temp for a given period of time. This usually means low temps and several hours cooking time. The end result is very flavorful, juicy, tender meat (although it's not just for meat). Additionally, because of the low and slow method and the precise temp control, you end up with perfectly cooked meat all the all through (medium rare at our house for beef). That's right, no tough, chewy, dry over-cooked meat.

As for equipment, I use a food sealer, but there are ways to do it with regular zip lock bags. For the container, I use a Coleman Party Stacker cooler and cut a hole in the lid so I can insert the Anova.  Then it's just a matter of filling the cooler with the appropriate amount of water, bringing it up to temp, then adding your bagged food and setting the timer. It's worth mentioning, after the cook you still want to usually sear your meat. I use a hot cast iron pan on my grill for this. This gives you the flavors associated with grilled meats (maillard reactions) and without it, it's closer to boiled meat.

So like my brewing and other food related posts,  I post this kind of stuff do that I make sure I do it The same way each time. It also helps if I decide I want to tweak things. So today I'm doing a tri tip with Santa Maria seasoning. I recently discovered a butcher shop near my house (Don's Meats) and I've been buying my tri tip there. The butcher is awesome and the meats have been great, plus it's always nice to support local businesses. Tri tip is great as a main dish, but we also like to slice it thin for sandwiches which is what we'll be doing with this one.

As described above, I sealed the tri tip in a vacuum seal bag then cooked it in my sous vide setup at 134F for 3 hours. Minimum time for this is about 2 hours and maximum is about 6 hours. I've heard too long in the water bath can change the texture for the worse, so I'd recommend shooting for something between 2 and 4 hours. It was then removed and seared on each side for about 1 min per side (flipped every 30 seconds). That's about all there is to it...eat it or chill out to be sliced later.
Seasoned, bagged, and ready for a bath

Right after adding meat, the temp only dropped 1 degree

Smoked Imperial Porter - 2018 Experimental

>> Sunday, April 22, 2018

Today I'm brewing an experimental version of my smoked porter. The first version of this beer took a gold medal for smoked and wood-aged beers and the second version did as well. The third version on sassafras didn't fare quite as well and I personally hated the rootbeer-like character it got from the sassafras. So today I'm brewing the fourth version which will be a split batch.

The biggest difference with this version is I'm using hickory-smoked malt that I smoked myself for my base malt. After primary, I'm planning on splitting off 2.5 gallons which will receive 1 pound of Maple & Bacon Smoked Candi Syrup. The home-smoked malt was cold-smoked using my newly completed malt tumbler. I suspect this version will have a much stronger smoke character because of the larger proportion of smoked malt, and because hickory trends to yield stronger smoke flavors compared to some other smoking woods. I love a strong smoke flavored beer, so I think I'll enjoy it, but it might be a little too strong for some.

Here's the recipe as I'm brewing it:

10.5# Hickory-smoked California Select Malt
2.0# Avangard Munich
1.25# Crisp Brown Malt
1.25# Crisp Crystal 77L
0.75# Crisp Pale Chocolate Malt (225L)
28g Magnum (60 min)
14g EKG (10 min)
Imperial Yeast Flagship
0.5 Whirlfloc
0.5t Yeast nutrient

Split batch with 1# of Maple & Bacon Smoked Candi Syrup added to half the batch after primary fermentation subsides.

Mash at 154F for 60 minutes, 90 minute boil, ferment at 60F

10 gallons distilled water using Beersmith's London water profile.

Brewing Notes
No issues. OG came in at 20.8/1.085.

Update 5/28/2018
I transferred this beer to two secondaries today. Half was racked onto the Maple Bacon Candi Syrup. I'll probably let this go about a week or two then add the wood for aging.

Update 7/2/2018
These variants went into kegs tonight. These have been sitting on hickory since 6/2/2018. Smoke on these is noticeable, but doesn't dominate. The maple-bacon variant is interesting. The maple character is subtle. The bacon component is a bit harder to identify. I'm interested to see how it changes as it carbs.


Update 8/5/2018
Both variants got bottled today. I'm really happy with the way both of these turned out. I don't know if I'd use the maple bacon syrup again. It's super subtle and I don't think it really adds much to this beer.
