Try Again Bohemian Pilsner

Posted on by

I’m craving a good Bohemian pilsner…especially that nice flavor and aroma of Saaz. My last effort was fairly disastrous, thanks to a bum batch of hops. Pro-tip: if it smells way too grassy before throwing them into the wort, throwing them into the wort won’t improve things.

In any case, I’ve got new hops, new grains, and a new recipe. I’ve cheated a bit with the grain bill, kicking in some melanoidin and Carafa III for a bit of extra malt flavor and color, respectively. For my interpretation I’ve amped up the Saaz a bit on the late-hop side, too.

Try Again Bohemian Pilsner

  • 10 lbs. Barke Pilsner malt (Weyermann)
  • 0.25 lb. Melanoidin malt (Weyermann)
  • 0.2 oz. Carafa III malt (Weyermann)
  • 2 oz. Saaz hop pellets (3.0% alpha), 60 minute boil
  • 1 oz. Saaz hop pellets (2.2% alpha), 20 minute boil
  • 2 oz. Saaz hop pellets (3.0% alpha), 10 minute boil
  • 1 oz. Saaz hop pellets (3.0% alpha), 5 minute whirlpool
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 tsp. Fermax, 10 minute boil
  • 2 pkg. Bohemian lager dry yeast (Mangrove Jack’s M84)

Target Parameters

  • Infusion mash to hit target of 149°, 60 minutes, batch sparge.
  • 1.052 o.g., 1.011 f.g., 5.5% abv, 36 IBU, 5 SRM
  • Water built from RO with 0.5 g CaCl, 0.5 g epsom salts, with 6.5 mL of 88% lactic acid added to mash to adjust pH

Procedure

  • I mashed in with 3.5 gallons of water at 160°, to hit a mash temperature of 150°. The mash was down to 145° after 65 minutes. I added 1.25 gallons of water at 185°, let sit for 10 minutes, vorlaufed, and collected the first runnings. I then added 3.5 gallons of water, let sit for 10 minutes, vorlaufed, and collected the remainder of the runnings.
  • In total, I collected 6.8 gallons of runnings with a gravity of 1.046, for 83% mash efficiency!
  • I started the boil, adding hops and various finings and nutrients per the schedule above. After 60 minutes of boiling, I turned off the flame and added the final charge of hops.
  • After 5 minutes of whirlpooling, I chilled down to 75° or so. Then, I transferred the wort to the fermenter, and let it chill overnight (~10 hours), down to 48°.
  • I brewed the beer on 12 May 2018. On the morning of 13 May 2018, I oxygenated the wort for 45 seconds and pitched the yeast (rehydrated in 1 cup of boiled and cooled water).
  • Starting gravity was 1.053, nearly exactly on target.
  • After pitching, I set the temperature on the fermentation chamber to 52°, letting the beer free-rise from 48°.
  • One day after pitching (14 May 2018), no fermentation activity was yet visible, but the fermenter gave off bubbles when I agitated it gently. By the morning of 15 May 2018 (48 hours post-pitching), visible krausen was forming.
  • On 20 May (7 days after pitching the yeast), I raised the fermentation temperature to 54°.
  • On 23 May, I raised the fermentation temperature to 56°.
  • On 25 May, I raised the fermentation temperature to 58°.
  • On 27 May, I raised the fermentation temperature to 60°. At this point, the gravity was 1.014.
  • On 2 June, I cold crashed down to 33°.

The Session #125 — Pale European Lagers: The Ultimate SMaSH beers

Posted on by

thesessionNote: This is my first time contributing to The Session, a monthly blogging challenge for beer aficionados. For The Session #125, Mark Linder chose the topic of SMaSH (single malt and single hop) beers.

SMaSH beers–those brews marrying a Single Malt variety and a Single Hop variety–are often promoted as something that’s interesting to try but not particularly versatile. As a homebrewer, I’ve usually thought of them as a tool to explore ingredients, perhaps fun as a technical gimmick but not necessarily a pathway to truly exceptional beer. Sure, you could get some good stuff, but it would lack complexity and get boring after a few pints. SMaSH beers were a way to turn out some pale ales with funky new hop varieties, but these were only a brief stop along the journey to a more worthy recipe. Don’t even bother entering them in a BJCP competition, because they won’t hold up well relative to their rivals with a longer ingredient list.

Then I discovered the Bohemian pilsner.

When I first sampled American-style craft beer, the cheap American lagers of my early days faded into mental oblivion. Why even bother with a watery fizz-drink, when you could blast your taste buds with a triple imperial IPA touting 190 IBUs, 12 percent alcohol, and five varieties of hops? Or what about a delightful English porter, with its malty backbone and slightly fruity yeast character? Clear beers were for quitters and college students. European lagers were mildly intriguing, but typified by badly aged and skunky six packs in green bottles. Why bother with that, when there was a world of fresh local craft brew and homebrew to explore?

An Archaeopteryx-linked beer requires the appropriate glassware.

My first homebrewed Bohemian pilsner (made with genuine Jurassic ingredients!)

Not too long ago, though, I decided to dip my homebrewing toes into the lagered waters. Bohemian pilsner (a.k.a., Czech pilsner, a.k.a., Czech premium pale lager in the 2015 BJCP guidelines) caught my attention early on…it was the original pilsner, after all! What better way to learn what this beer is all about?

Yet, I was shocked by the simplicity of the classic recipes! Bohemian pilsner malt. Czech-sourced Saaz hops. Soft water. Clean lager yeast. The rest is just up to technique–in particular, a good decoction mash was apparently the key to success.

My first attempt at a Bohemian pilsner wasn’t perfect, but wow, it was pretty darned good. This was the first time I consciously experienced Saaz hops, finally getting a name to match with that distinctive aroma and flavor. It was also the first time I experienced a genuinely fresh European-style lager in the United States, and I finally knew what the big deal was all about.

This spurred a realization. SMaSH beers weren’t just for pale ales. In fact, pale lagers are the most reliable ticket to SMaSH success. Quality malt. Quality hops. Careful water chemistry. A clean fermenting lager yeast. A bit of skill. All of this combines to a memorable and surprisingly complex brew. Of course, Czech pilsner isn’t the only lager style with a simple recipe. Munich helles, German pils, and others jostle alongside in the running. Any of these can be done quite well with a short shopping list. This is what makes them so hard to do exceptionally well, perhaps–any flaws can’t hide behind crystal malt and yeast esters.

So, what’s the style best suited to a SMaSH beer? I love all of my European pale lagers, but Bohemian pilsner wins for me every time.

Big Batch Update: Saison, Amber Ale, Pilsner

Posted on by

There’s lots to report with kegging and fermentation for a few recent batches. So, here’s what’s new:

  • Thumbspike Saison 2.0
    20170528_144954

    • This might have had the quickest turn-around on any kegged beer I’ve ever done! I brewed the beer on 12 May 2017, starting with an 80° fermentation temperature. On 16 May, I raised the temperature to 85°. Everything really churned along, from start to finish (as you might expect with fermentation at those temperatures)! I kegged the beer on 20 May 2017, with a final gravity of 1.004. That works out to 6.7% abv. I’ve had it on tap for about a week, and it’s a pretty interesting and enjoyable beer. All of the ingredients melded together quite nicely, and I am pleased with the results. It’s a very refreshing brew for a warm afternoon on the patio.
    • My first impressions are that it has a very lightly fruity aroma, with a slight tartness on the flavor. Head retention seems pretty miserable at this point, but I don’t know if that’s a real feature of the beer or because I didn’t wash my glass from a previous beer before pouring this one.
  • Hell Creek Amber Ale 1.1
    • I brewed this beer on 14 April 2017, with a starting gravity of 1.060. I kegged the beer on 7 May 2017. Final gravity was 1.016, which equates to 5.8% abv.
  • Czech-ed Out Pilsner
    • This batch has the honor of being my first dumper, ever. I’ve weathered warm fermentations, low gravities, and incomplete fermentations, and have always soldiered through in the end. Alas, this particular batch just wasn’t any good. The culprit wasn’t infection, bad fermentation, or anything like that. It was bad hops! As noted in my original post, the late hop addition smelled really grassy. I should have known better than to add them to the kettle, but wasn’t quite that smart. So, I kegged the beer, carbonated it, and pulled my first sample…to a whiff of pilsner that smelled pretty much like freshly mown lawn, and not in a good way. It was almost reminiscent of jalapenos, but in any case was not reminiscent of what a good European pilsner should taste or smell like. Lesson learned!
    • In terms of fermentation history, I started fermentation at 50° on 9 April. I raised the beer to 65° on 21 April, and then dropped it to 33° on 30 April 2017. I kegged the beer on 14 May, at which point it had a final gravity of 1.011. This equates to 5.6% abv.

Czech-ed Out Pilsner

Posted on by

My first attempt at a Bohemian pilsner turned out reasonably well, but it also had a few areas of potential improvement. The flavor was a little less well rounded than I hoped for, so I aimed for a brew that added in a small percentage of crystal malt. Additionally, the color on my previous batch was a touch paler than desired, so for this version I’m adding in a tiny percentage of Carafa II to deepen that up a bit.

20170409_125350

The recipe today is very loosely based on “Czech It Out” pilsner, published in the January/February 2017 issue of BYO. I’ve made some substitutions and adjustments for the malts and hops, but the overall gist is still there. Lots of Bohemian malt, lots of Saaz hops! Note that I did use a touch of Warrior for the bittering addition; my on-hand Saaz was low in alpha, so I needed to beef up the bittering with another hop. I also had to substitute in American crystal malt for Carahell, based on what was at my local homebrew shop.

I had a few members from my homebrew club over for the brew afternoon. Although I can do pretty much everything solo, it was nice to have the extra company!

Czech-ed Out Pilsner

  • 9.5 lbs. floor-malted Bohemian pilsner malt (Weyermann)
  • 0.5 lb. 10° crystal malt (Briess)
  • 0.25 lb. acidulated malt (Weyermann)
  • 0.2 oz. Carafa Special II malt (Weyermann)
  • 0.47 oz. Saaz hop pellets (5.6% alpha), 60 minute boil
  • 0.25 oz. Warrior hop pellets (15.8% alpha), 60 minute boil
  • 2 oz. Saaz hop pellets (3% alpha), 15 minute boil
  • 2 oz. Saaz hop pellets (3% alpha), 5 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 0.5 tsp Fermax yeast nutrient, 10 minute boil
  • 2 pkg. Pilsner Lager yeast (WLP800, White Labs)

Target Parameters

  • 1.053 o.g., 1.013 f.g., 5.3% abv, 40 IBU, 5 SRM, 5 gallons into the fermenter

Procedure

  • A week in advance, I prepared the yeast in a 2L starter. It ran for three days, and then I cold-crashed it in the fridge. Prior to pitching, I decanted off ~1L of spent starter.
  • I mashed in with 3.45 gallons of water at 163.7°, to hit a mash temperature of 152°. This was built up from RO water with 1 g of calcium chloride. After 60 minutes, I added an additional 1.5 gallons of RO water at ~160°, let sit for 10 minutes, and then vorlaufed. After collecting the first runnings, I added another 3.75 gallons of RO water at 180°, to raise the mash up to 165°. I let the mash sit for another 10 minutes, and collected the second runnings.
  • In total, I collected 7.3 gallons of wort at a gravity of 1.041–nearly right on my target, for ~76% mash efficiency.
  • This batch used a 90 minute boil, and I added all of the hops, etc., per the schedule. After a full 90 minutes, I turned off the flame and started chilling.
  • I’ll note that the hop pellets I used for the aroma additions (last 15 minutes of boil) had a strong herbal and almost “green” character. The latter component is maybe more than I care for, but we’ll see how it all ends up after fermentation.
  • I chilled the wort to 75°, transferred to the fermenter while aerating, and then put it in the fermentation chamber. Once everything was down to 54°, I pitched the yeast.
  • Starting gravity was. 1.054, and the beer was brewed on 9 April 2017. I’m fermenting the beer at 50°.

Beer Tasting: Lithographica Pilsner

The keg for my Bohemian pilsner is long past kicked, but better late than never, right?

  • The Basics
    • Original gravity = 1.053; final gravity = 1.011; abv = 5.5%; estimated IBU = 39
  •  Aroma
    • Light bready aroma, with a moderate spicy hops note. I might detect a very, very faint fruitiness, but this seems to come and go, so I’m not certain it is really there.
  • Appearance
    • Clear, but not brilliant, with a moderate yellow color. The head pours rather high when first poured, but settles down to a low head with good coverage. The head is fine and white.
  • Flavor
    • A moderate hoppiness is at the fore, moderately balanced against a decent but not overwhelming maltiness. The malt has a bready/grainy character. As I drink this, the hoppiness fades out nicely on the finish.
  • Mouthfeel
    • This is a beer with modest body and a medium rather than dry finish. Carbonation is moderately high.
  • Would I brew this again?
    • This beer is a pretty respectable first go at a Bohemian pilsner. It’s quite drinkable, and there isn’t anything I would call a major flaw. If I do this recipe again, I would up the maltiness a touch, darken the color to more gold than yellow, and work on improving the clarity just a little. Clarity could be fixed by more careful racking, and a little bit more time lagering before initial tapping. For increased maltiness, I might add another grain or two to the malt bill (e.g., Carapils), or else boil the decoctions for a longer stretch. This would also help burnish the color to the golden sheen that is more appropriate for the style.
