English Barleywine V

This will be my fifth English Barleywine brewed over the last five Memorial days (see 2014, 2015, 2016, and 2017).  I've really enjoyed trying various approaches on a fairly narrow style of beer.  All versions of the beer so far have brought some unique things to the table but also have quite a bit in common.

I developed the previous four beer recipes myself.  For this new beer I've decided to try somebody else's version.  I found this interesting recipe on the "Shut up about Barclay Perkins" historical beer blog for the original 1967 version of Thomas Hardy Barleywine.  The recipe interested me due to the high target OG (1.110), high level of hopping with low AA hops (10 oz of boil hops), and unusually high fermentation temperature (low-mid 70s) in order to get more fruity ester character.

I've made a few modifications to the recipe based on my system performance and available ingredients:
  • I had to increase the amount of grain based on an assumed ~60% efficiency.  This drove a larger grainbill such that I couldn't fit it all into my mash tun.  Based on this I'll be doing two mashes with an extended 4 hr boil
  • I couldn't get the WLP099 yeast the recipe calls for (which is reported to be the yeast strain used by Eldridge Pope brewery for the original beer).  I will use Danster Nottingham yeast instead.  I'm going to use one packet of dry yeast for this beer which I'm thinking may help increase the ester production.
  • I'm mashing a bit higher (153 F) to hopefully get a bit higher FG.  The recipe reports that the beer finished at 1.047 which is pretty insane.  In the comments the brewer reports that the beer likely fermented further during a long secondary period.
  • The hops I am using are a bit higher AA then what the recipe calls for.  I'm delaying the hops until later in the boil to hopefully get closer to the intended bitterness.
So, I'm excited to be brewing this huge crazy beer.  With a 4 hr boil and two mashes this is going to be one hell of a brewday.  I expect I'll be happy I only brew one of these a year after today.

Brewing Notes:
  • 5/27/18 - Prepared 2 oz of oak to age with this batch
    • Boiled it for 5 min or so to remove some to the tannin
    • Wrapped in foil and toasted in the oven at 400 F for 3 hrs.  It produced a really nice vanilla aroma.
    • Will use this in the long secondary/aging period
  • 5/28/18 - Brewday - 8:00 AM to 3:30 PM - Including Setup and Cleanup
    • Heated 8 gal of spring water to 165 F
    • Milled half the grain
    • Added half the CaCl and Gypsum to the grain
    • Moved 6 gal of water to the mash tun
    • Cycled through the rims until the system had settled out to 165 F
    • Added the grain for the first mash - stirred well to eliminate dough balls
    • Cycled the RIMS at 155 F. The beer settled down to 152-155 F initially
    • Mashed for 60 min
    • Heated 8 gal for the sparge to 185 F
    • Ran off the mash water for first runnings.  This got me about 4 gal of 18 brix wort (1.074).  This is about 55% efficiency.
    • Fly sparged until 7 gal had been collected.  I stirred the grain quite a bit during the fly sparge.  Gravity was 13.8 brix (1.056) at this point which would be 73%.  So, quite a bit more sugar was extracted over and above the first runnings.
    • Started heating after the first runnings and had it to a boil very early in the fly sparge
    • Boiled for 2 hrs which got me down to 3 gal
    • Heated 8 gal of strike water for my second mash
    • Cleaned the mash tun and milled the second half of the grains.  Added the other half of brewing salts to this
    • Moved 6 gal to the mash tun and cycled until the system was at 165 F
    • Added the second mash grain and stirred well to eliminate dough balls
    • Cycled the RIMS at 155 F for 1 hr.  Temperature stayed between 152 and 155 F this time as well.
    • Heated 8 gal of sparge water to 185 F
    • Drained the first runnings into the boil kettle and started the heat again
    • Fly Sparged until I'd collected 10 gal of wort.  Measured the gravity as 18 brix which puts me at about 69% efficiencyHad the wort back up to a boil by the end of the fly sparge
    • Boiled for 2 more hours
    • Rehydrated dry yeast packet in a cup 95 F spring water
    • Added 60, 50, 40, and 30 min hops
    • Added Irish Moss at 15 min
    • Added the wort chiller to sanitize with 5 min left in the boil
    • Chilled down to 80 F
    • Transferred the beer into a bucket fermenter.  Let the beer fall a couple feet to aerate.  Pitched the yeast during the transfer
    • Measured the gravity as 1.120 and collected ~5.25 gal (left quite a bit of wort in the hops at the bottom of the boil kettle).  This is a final efficiency of ~58%.  
    • Decided to add ~0.75 gal of spring water to get up to the target 6 gal.  This lowered the gravity to ~1.105
    • Moved the beer to the fermentation chamber with a blowoff tube setup.  Set the temperature to 68 F initially. 
  • 5/29/18 - Allowed the fermentation chamber to rise up to 72 F.  The beer is starting to form some krausen this morning but no bubbling yet.  By this evening the beer was bubbling off very vigorously.  I found that beer was being pushed out the lid.  It turned out the blowoff tube was clogged with a chunk of hop and krausen.  Once I cleared that the pressure subsided quite a bit.  I was very lucky the lid didn't pop off (I'm an idiot but a lucky idiot).

  • 5/30/18 - Still getting a steady production of C02 from the beer but the blowoff has subsided a lot.  I had captured the blow off in a container.  I measured the amount of beer that was blown at 1.5 quarts.  I tasted it - it was still pretty sweet and raw tasting and also very bitter.  The fermentation is putting of a slightly fruity aroma so far.

  • 6/2/18 - No more activity in the blowoff.  I switched it out for a 3 piece airlock.  I need the fermentation chamber for another beer so I'm moving the barleywine to the mid-60s basement to complete primary.  The beer smells very estery at this point.
  • 7/22/18 - I've ended up leaving this one on the yeast cake a bit longer than planned.  I'll be moving it into secondary here in the next couple days.  Moved it to the fermentation chamber to cold crash before the transfer - set the chamber to 34 F. 
  • 7/25/18 - Added gelatin to drop out the yeast
  • 7/29/18 - Transferred the beer to a glass carboy with 2 oz of oak to secondary.  Measured the gravity of the beer as 1.028.  It is fruity and malty with a pretty nice hop flavor going a long with it.  I was worried it would end up too bitter - this is not the case thankfully.
  • 11/25/18 - Bottled today with a packet of rehydrated Red Star Primer Cuvee yeast and 5 oz of sugar.  Ended up with a bit over 5 gal of beer which got me 53 bottles.  The gravity on this measurement was 1.030.  The beer has a really rich and complex malt flavor with a bit of fruity yeast ester.  Hop flavor has largely fallen off but there is still some bitterness in the finish.
  • 1/13/19 - Tasting Notes - This has a lot going on between the malt and ester flavors.  These get along very well together and make for a nicely complex beverage.  It is a sweet beer but it's not cloying or difficult to drink.  I think the hop bitterness the beer has retained over the long aging does a nice job to balance the finish such that you're called to take another sip.  I think this was a very good recipe.  I think this one will age nicely and look forward to many more tastings.
  • 5/26/19 - Tasting Notes (2019):
    • Aroma:  Caramel and fruit ester - raising and apple maybe.  Also pick up a berry like fruitiness (strawberry?).  Maybe get a bit of herbal hop aroma.  Really lovely aroma
    • Appearance:  Very dark red or light brown.  Poured with a 2 finger head that lasted several minutes and then faded to a thin ring.  Very clear
    • Flavor:  Rich bready flavor along with caramel malt which blends nicely with the fruity yeast ester character.  Light bitterness in the finish which balances out the sweetness.  Some alcohol comes through
    • Mouthfeel:  Medium bodied and pretty sweet.  Smooth drinking
    • Overall:  Complex and rich malt and yeast flavors.  Still has a bit of hop character left which makes for a bit different balance than the others
  • 5/23/20 - Tasting Notes (2020):
    • Aroma:  Light fruity ester and caramel malt.  Also pick up some herbal hop character faintly
    • Appearance:  Pours with a finger of head that fades down to a ring fairly quickly.  Leaves lacing.  Reddish brown in color
    • Flavor:  Toasty bread and caramel malt up front.  Yeast ester comes through next although it is mild.  The toast then rides through the finish.  There is also a fairly firm bitterness that balances the malt in the finish.  Get a bit of herbal hop flavor in the mix as well
    • Mouthfeel:  Medium bodied and a bit sweet.  Smooth drinking beer
    • Overall:  Really lovely flavor to this beer.  It has a bold maltiness with a very nice hop presence.  There is also a good yeast character that mixes well with the other elements and lends complexity.  Pleasure to drink
  • 5/30/21 - Tasting Notes (2021):
    • Aroma:    Dark malt and caramel aroma - cookie like.  Light fruity ester character in there as well
    • Appearance:  Dark gold in color and clear.  Pours with a 1 finger head that is slow to fade.  Leaves some lacing
    • Flavor:  Sweet rich bready malt, some toast and dark caramel.  A bit of fruity ester in the background.  The finish has medium bitterness that is balanced by the rich malt flavors that linger for a bit.  A little boozy
    • Mouthfeel:  Medium bodied and lightly sweet.  Smooth drinking.  Warming alcohol is detected
    • Overall:  Complex with bold flavors.  Malt is the star of the show
  • 5/28/22 - Tasting Notes (2022):
    • Total (36 of 50):
      • Aroma (7 of 12):  Boozy aroma most prominent.   Has some caramel and some overripe fruit like yeast character.  Maybe get a bit of toasty bread in there too.  Has kind of a musty character.  Not picking up on any hops in it.  
      • Appearance (3 of 3):  Pours with 1 finger head that fades down to a thin layer after a couple minutes.  Reddish brown and pretty clear.
      • Flavor (15 of 20):  Toasted bread and dark/burnt caramel flavors up front.  Get a wave of alcohol character in there up front too.  After that first wave a bit of fruit character comes through - apple maybe.  The finish is mostly dark toasty malt flavor with a bit of fruity malt.  There is a mild but fairly deep bitterness to it still on the finish as well.  It's pretty well balanced actually.
      • Mouthfeel (4 of 5):  Medium bodied and slightly sweet.  Coats the mouth and leaves a sticky sensation.  Smooth drinking with a noticeable alcohol warming
      • Overall: (7 of 10):  This is fairly boldly flavored beer with a pretty good level of complexity.  It has a pleasant and rich malt character that I really like.  The fruity esters are more mild and a little strange but not bad at all.  It is pretty easy to drink with a fairly firm hop bitterness which balances the beer nicely - something that feels more like drinking than sipping.
  • 5/28/23 - Tasting Notes (2023):
    • Tasting Notes (37 of 50):
      • Aroma (7 of 12):  Some fruit and an almost spicy character (almost like candy).  Booze.  A bit of caramel malt in there as well.  
      • Appearance (3 of 3):  Dark brown and very clear.  It pours with a 2 finger head that lingers as a thin layer for several minutes
      • Flavor (16 of 20):  A little fruit up front followed by dark caramel and toasted bread.  Maybe a bit of graham cracker in there as well.  It has a boozy kick in the middle.  The finish has a medium bitterness which lingers and is balanced by a rich malt flavor with just a hint of sweetness.
      • Mouthfeel (4 of 5):  Medium bodied with just a slightly sticky mouthfeel  Has a very slight astringency.  Slight alcohol warming
      • Overall (7 of 10):  This is a fairly complex beer with a mostly malt forward character.  Flavors are pretty bold.  I enjoy the balance of it with some hop bitterness remaining.  Tastes like a very strong beer.

Lesson Learned:
  1. I was a bit disappointed to have not gotten WLP099 - Super High Gravity yeast.  I was excited to be allowing fermentation to warm to the mid 70s with that yeast.  I'm not confident that Nottingham will perform well that warm so I'll keep it under 72 F.  I should have planned ahead better - could have ordered something online if I'd searched for the yeast a week earlier than I did.
  2. I'm a bit conflicted about my decision to top up the beer.  I topped up with 3/4 a gal in order to get to 6 gal after seeing that I overshot by 10 gravity points.  I didn't do the calculation first and ended up diluting it down to under the target 1.110.  I think I would have preferred to have met the OG target rather than the volume target in retrospect.  I should have done the calculation before adding water.
  3. I liked the method of draining the first runnings first and then fly sparging through a dry grain bed.  It seemed like that helped the efficiency somewhat as I could stir the grain bed as I went

Sour Blonde Status Report - 2018

Today I'll be doing a new tasting for the Lambic inspired Sour Blonde Ales I've been brewing and aging over the last 3.5 years.  I currently have 13 fermenters going.

After doing a tasting of my Sour Blonds 6 month ago (see previous tasting notes here) I found that the older beers were not very interesting so I decided to add some young, pre-soured, top up beer which I'd hoped would add some complexity.  We'll find out today whether that worked.

Regardless, I'm finally ready to start using these beers to create some bends.  I'll do a plain, cherry, and raspberry blend of these beers.  These tasting notes will be a good basis on which to decide the beers that will make up each blend.  I think any bland beer still be good components for use with fruit.

I have 6 beers in glass carboy, 5 in buckets for long term aging, 1 backfill batch and 1 in a better bottle.  I plan to condense my beers down to 12 fermenters and use 3 each year for blending.  I anticipate that beers will get intermixed over time so I've decided to track the progress of the beers by the fermenter rather than the beer number.


I'm excited to be tasting these again.  Can't wait to start my blending.

This leaves out the following beers that I've decided not to taste so far:
  1. Sour Blonde 5.1.1 which was a spontaneously fermented beer I made on 11/19/17.  I plan to try another spontaneous fermented beer in the fall.  I've decided that the potential de-motivator of finding this beer isn't very good is a stronger reason to not try it then the potential opportunity to learn something from this batch.
  2. Sour Blonde 6.1.1 which is fermenting with Bootleg Biology Funk Weapon #1 since 3/25/18.  I haven't decided if this one will be used to backfill one of the other fermenters after the blending session.
  3. Sour Blonde 1.6.1 which has been primary fermented with my blend of lacto and brewers yeast since 3/25/18.  I plan to pitch it onto the yeast cake currently being used by Sour Blonde 1.5.1.

Berliner Weisse Take III - Tasting Notes

This was a Berliner Weisse I brewed back in March with Grapefruit Zest and Dry Hopped with Cascade.  This is one of my favorite styles of beer.  The lightness and low alcohol (this one finished at less than 3%) combined with a really nice level of complexity make for a really interesting package.

Fermentation of the beer was pretty simple in that I just used a house blend I've been propagating of brewers yeast and Lacto Brevis over the last couple years.  I was a bit concerned that it would develop a good level of sourness.  It turned out that it did.  This was much simpler than trying to sour using grain.

The grapefruit was a fun touch.  The flavors are really compatible with the beer and they've lasted the last couple months.  The hops turned out not to last (although they were nice for a couple weeks or so).

Happy to finally be doing some testing notes.


Tasting Notes:

  • Aroma:
    • It has a fruity yeast character along with a slight sour aroma.  Grapefruit aroma is prominent as well
  • Appearance:
    • Straw color and cloudy.  It pours with a 2 finger head that quickly dissipates down to nothing
  • Flavor:
    • Tart with a balance between bready malt and a fruity character - I think this is a mix of yeast and the grapefruit.  The tartness is about what I would expect for a Berliner Weisse - not overwhelming.  In the background the beer has sort of a cheesy and funky flavor
  • Mouthfeel:
    • Light and quite dry.  The acidity prickles the tongue.
  • Overall:
    • Very refreshing beer that is easy to drink in quantity.  I think the sourness is at a really satisfying level and it has a pleasing level of complexity.  The grapefruit is a subtle addition but I think it blends in with the overall flavor profile nicely.  The hops were quite nice but I think I prefer it without them.

Munich Dunkel

I've been planning on brewing this beer for the last two years.  I have really enjoyed the two Lagers I've brewed so far (Dark Lager and Munich Helles).  They both turned out to be smooth, clean, and easy drinking beers.  There is an elegance to these styles that makes for a really nice drinking experience.  They are simple and malty but they also have a depth of flavor that stands on it's own.  These characteristics make the extra work of brewing a lager worth while.

I'm going to try brewing up a Munich Dunkel.  I'm going to up the ante on this beer by trying a decoction mash.  I am going to use a recipe from a YouTube demonstration on decoction mash by "BrewingTV" (video is here and the recipe is here).  Decoction mashing is traditionally used by German brewers to get good extraction from their grain.  It involves a stepped mash where a part of the mash is pulled off the main mash, boiled, and then added back to the main mash to bring up the temperature.  The boiling darkens the beer and (reputedly) produces unique malty flavor compounds.  There is a lot of controversy about whether decoction is worth the effort as you can probably duplicate a lot of these flavor compounds in a simple single temperature mash through the use of specialty grains.  I would like to find out myself.

Based on the video, I plan on following the following decoction process:
  1. Protein Rest:  Dough in with the goal of hitting a starting temp of 122 F (Rest for 10 min)
    • Will shoot for 2 quart of water per pound of grain  
  2. Decoction 1:  Pull 10 quarts of the thick mash to a separate pot, heat to 158 F for a Sacch Rest (Rest for 15 min), and then boil for 10 min
  3. Sacch Rest 1:  Add the decoction back to the main mash to bring it to 148 F (Rest for 30 min)
  4. Decoction 2:  Pull 5 quarts of the thick mash to a separate pot and heat to a boil for 10 min
  5. Sacch Rest 2:  Add the decoction back to the main mash to bring it to 158 F (Rest for 15 min)
  6. Mash Out/Recycle:  Add 2 gal of boiling mash out water and cycle through RIMS until the mash is at 175 F
Doesn't seem like it should be difficult but I expect it is going to be a long brewday.  Will be interesting to see if this will be worth it.

Brewing Notes:
  • 5/12/18 - Made a 2 litre starter from grain (1.055) and setup on the stir plate at cellar temperatures.  Pitched the yeast and let it propagate over night.  Was a pretty subdued fermentation with just a thin layer of foam on the top.  Tasting a sample of it the next morning revealed it had fermented it pretty dry.
  • 5/13/18 - Brewday - 9:30 AM to 2:30 PM - Including setup and cleanup
    • Heated 9.5 gal to 140 F
    • Added 5 gal to the mash tun - Settled at 133 F
    • Milled the grain.  Added CaCl to the grain
    • Doughed in with the grain - temp settled to 128 F
    • Let rest for 10 min
    • Moved 10 quarts of the thickest portion of the grain over to a separate pot for the first Decoction.  Heated this on my turkey fryer until it was in the high 150/low 160 temperature range.  Let it sit at this temperature for 15 min
    • Brought the first decoction to a boil.  Boiled for 10 min.  The mixture is noticeably darker after this
    • Added the decoction back to the main mash.  Temperature of the main mash only raised up to mid 130 F with this.  Setup the RIMs to cycle until the temperature had settled to 148 F.  Mashed for 30 min.
    • Pulled second decoction (5 quarts) of mash and boiled this for 10 min.  Cycled the RIMS to ramp up the main mash up to 158 F during this
    • Added the second decoction back in.  This raised the temperature to high 150/low 160 F.  Cycled the RIMS for 15 more min
    • Raised the RIMS temperature to 172 F and cycled while I heated 10 gal of sparge water to 180 F
    • The wort is 20 brix at the end of the mash
    • Fly sparged
      • Drained all the wort from the grant into the mash tun.  Flushed the grant with 1 gal of sparge water to ensure everything was rinsed through the RIMS
      • Started the flow of sparge water.  Drained to the grant and then pumped into the kettle
      • After collecting 3 gal of wort the gravity was 13 brix
      • Started to heat the kettle after collecting about 4 gal
      • Stopped the sparge after collecting about 5 gal - had about 1.5 gal of water above the grain bed at this point.
      • Collected ~8.5 gal.  Gravity at the grant was 2-3 brix at that point
    • Had it to a boil just as the sparge ended
    • Added hops when the hot break had cleared
    • Boiled for 60 min
    • Added irish moss with 15 min left
    • Put in the wort chiller to sanitize with 5 min left
    • Chilled to 70 F
    • Transferred to SS Brewtech Brewbucket fermenter.  Added yeast during the transfer.
    • Moved to fermentation chamber to chill to 53 F
    • Collected 6 gal and measured the gravity as 1.052
  • 5/14/18 - Fermentation was off to a vigorous start by this afternoon
  • 5/15/18 - Still getting a bit of bubbling in the airlock.  The yeast is putting off a pretty strong sulfur aroma.  It is pretty prominent outside of the fermentation chamber as well.
  • 5/23/18 - Allowed the beer to rise up to the mid 60s for Diacetyl cleanup
  • 5/28/18 - Moved the beer out of the fermentation chamber to the mid-60s basement to make room for another beer.
  • 6/2/18 - Moved the beer back into the fermentation chamber set to 36 F for Secondary/Lagering
  • 7/12/18 - The beer has been lagering at 36 F for the last 6 weeks.  I'm planning on bottling tomorrow.  Added gelatin to fine the beer.
  • 7/14/18 - Bottled this beer with 4 oz of priming sugar.  Got 59 bottles out of ~5.75 gal of beer.  measured the FG as 1.014.  The beer has retained the rich malty flavor from the wort and has a really nice clean fermentation profile.  I think its going to be very nice.  Will give it a couple weeks to carb up.
  • 8/30/18 - Tasting Notes - Rich and complex malt flavor which is comparable to many of the German made examples I've had.  Easy drinking and refreshing which makes drinking 2 to 3 pretty easy.  Nice clean lager profile - it was a well executed fermentation and lager period on this beer.  One interesting note:  this beer has, by far, the least sediment per bottle of any of the beers I've made.  This hasn't prevented the normal carbonation from occurring.  The six odd weeks of lagering is likely responsible but I also gave it some extra time to fine with gelatin.  I may have to try something like this with future beers.

Lessons Learned:
  1. I was impressed by the rich malt flavor of the beer.  I tasted quite a bit of the grain from the boiled decoction mash and they were very nice and rich.  I'm inclined to think that the decoction did have some flavor impact.  I think I'd like to try this again.
