Science & Art #4: Blend & Tasting Notes

This is my fourth blend in the Science & Art Series, a group of blended saisons and wild ales. The components of this blend were Demeter Vert, Namur (Meyer Lemon), and Flowerfield. The idea behind blending is to create something that's better than the sum of its parts. Here, I had three beers that ranged from okay to quite good, with each one either having something that I didn't quite like (Namur and Flowerfield), or that were almost there, but could use an extra boost (Demeter Vert).

Demeter Vert was going to be the star of the show, as the lime saison base was something that I really enjoyed. I've been tweaking the recipe for that one across batches and think that I have most things generally dialed in, but this batch was lacking a bit of extra oomph. I think this is due to the fact that this beer was my first time using my yeast/bacteria Blend 05, and the Brett and bacteria weren't a big enough portion of the blend. Based on that, I was looking for something that could give this base a bit more flair.

For each of the previous versions of Science & Art, Citrine -- which is my house blonde wild -- had been a component of the blend, adding some acidity and fund. In this case, I was looking for something that was clean and not really funky, though I was hoping for a bit of acid to boost the overall flavor profile. My first thought was Namur (Meyer Lemon), which was just far too lemony. That beer was my first time using Meyer Lemon (or any type of lemon, for that matter) in a beer, and it was far too much. I was a bit surprised by this, as the use was generally in line with other citrus beers that I've done (Demeter Auran, the above-discussed Demeter Vert, and a few others), and those generally have hints of citrus without being too overpowering.

The lemon juice that was used alongside the zest in that batch of Namur created a good amount of acidity, and the beer itself was very clean and not at all funky, so after a few quick small-scale blends with Demeter Vert, I knew that I'd like to add that to the blend. That blend was still a bit citrus-heavy (though not obviously heavy on either lemon or lime), so I looked for something else to add in.

The perfect answer was a bit of Flowerfield, which is a collaboration that I did with Matt over at Stickman Brewing (he runs A Ph.D in Beer) over Memorial Day weekend 2014. We brewed that as a blonde Brett saison with Nelson Sauvin. To ferment that batch, I used the Yeast Bay Saison/Brettanomyces Blend and I wasn't a huge fan of the profile. There was something in the finish that was slightly acidic and just didn't quite agree with my palate, though others enjoyed it. (Matt, for one, agreed with me.) There wasn't anything wrong with the beer, so I didn't want to get rid of it, but I though blending would be a good option for some of what was remaining in the keg.

After messing around with the ratio of the three beers using a pipette and sample glasses, I settled on a blend that was four parts Demeter Vert, one part Meyer Lemon Namur, and one part Flowerfield. From there, I transferred into a bottling bucket, mixed in the priming sugar, and bottled. Since the Flowerfield portion was already kegged and carbonated and the Meyer Lemon Namur was in bottles, I needed to reduce the sugar so that I didn't get too far over my goal of 3.0 volumes of CO2. (Since the Namur was in bottles, I added that portion last, slowly pouring from chilled bottles into the bottling bucket with the neck submersed in the liquid in the bucket.) Given this, I decided to put the target at 2.2 volumes (almost purely guesswork) in the priming calculator, and then used that as my sugar level for bottling.

And now for the tasting notes, which are coming around 3.5 months after I bottled up the blend.  For tasting notes from others, you can follow the beer here on Untappd.




Appearance: Clear, bright light yellow with a fluffy white head. Good retention and plenty of lacing as it went down. Visible carbonation bubbles rising through the liquid. Has just about all it needs for a saison. I generally don't pay too much attention to whether my saisons are clear or hazy so long as they have a nice head of foam and good retention, as hazy beers seem a bit more rustic, which is something I don't mind at all when dealing with saisons with Brett and/or lactic acid bacteria (LAB).

Aroma The citrus citrus isn't too strong in the nose, and is mostly generic but tending a bit more toward the lemon. Lime there as well. I'm glad that most people haven't been able to pick out the exact citrus, as one of my goals here was to really knock down the lemon of the Namur variant, while preserving the lime from Demeter Vert. At this point, I think I was pretty successful there, likely only picking out the distinct citrus fruits as I know what went into the beer. As it warms, there is also a bit of an almost honey-like character, mixing with a bit of apricot. Maybe a bit of green grape there as well, which could be coming from the Nelson Sauvin that was used fairly heavily in Flowerfield.

Flavor: Lightly tart with just a hint of backing grain. Very clean without any funk, focusing in on the light acidity and citrus character. Maybe a bit simple, but I wasn't looking for this to be an overly-complex beer. The citrus character is just about where I want it, with some Brett-induced fruitiness in the background. The light acidity comes from the citrus, as well as from whatever lactic acid bacteria are now in this fermenting blend. (I typically use buckets that I use a carboy brush to clean, so there are plenty of scratches for LAB from dreg batches to take hold.)

Mouthfeel: Again, quite light, and also extremely crisp. The carbonation is high without gushing or being too bubbly. Clean finish, not much lingering taste. This would be a great beer for the summer, though I'm not sure I'll have much, if any, last until then. The Yeast Bay Wallonian Farmhouse is the base yeast for the fermentation blend of Demeter Vert, and I think it contributes a nice bit of body in beers that are otherwise bone dry. That's certainly apparent here. The water profiles of the base beers also likely contribute to this, as I tend to go relatively heavy on the chloride for saisons, where it seems like many other saisons are too sulfate heavy for my tastes. 

Overall: I'd describe this as simple, but elegant. Really easy drinking and is something that I'll try to re-create in the future, potentially all in the same beer by using the base for Demeter Vert and then adding in just a touch of Meyer Lemon and also maybe dry hop with some Nelson.

Demeter Vert (Batch 03): Tasting Notes

I've had this one (recipe) on tap for a month or so now, and I'm finally getting around to reviewing it.  While it is really nice having this on tap, I do really prefer to have my saisons bottle conditioner, for several reasons.  First off, based on experience with kegging partial batches and conditioning the rest in the bottle, I believe that the bottle conditioned beers have a better mouthfeel.  There's something about the conditioning process that really makes the bottles jump, both figuratively and literally.  For the latter, there's nothing like popping a 750 of a farmhouse beer and see
ing that slow gush.


Aside from the conditioning effect itself, which is a fairly minor thing for me, what I really like is being able to sit on the bottles and see how they develop, particularly since everything that I'm doing nowadays has Brettanomyces and lactic acid bacteria (and likely other critters as well).  The Brett helps scavenge any additional oxygen, and also does a great job cleaning up the diacetyl that is created by Pediococcus.  This is particularly important for a lot of the beers that I've done lately, as I've added plenty of Crooked Stave dregs, and it seems as though they've got a strain of Pedio that really, really likes to kick up a lot of diacetyl.


With this diacetyl creation, there are issues with kegging and then trying to bottle for friends, particularly if that means that the bottles are going to become warm for some time and allow the Pedio to get started again.  Without Brett to clean up, I may end up sending out buttery saisons, which is something I certainly don't want.  With Pedio in the bottles, there's likely Brett as well, although the latter may not be all that viable, as Chad Yakobson at Crooked Stave has mentioned (video link) that he's seen issues with Brett effectively dying off after being refrigerated for too long.

With those thoughts aside, here are the tasting notes for the beer:

Appearance: Slightly cloudy light peach color with a nice initial head, though the retention could certainly be a lot better.  Another unfortunate side effect of draft beer, in my experience.  Even when pouring with a thick, rocky head using flow control faucets, the head ends up not lasting for more than a few minutes, and not much lacing is produced.

Aroma: Just a touch of sulfur in the background behind notes of lime and soft malt.  A bit of wheat and earth.  Very faint background rye spice.

Flavor: Much more complex than the nose, with the rye coming through a bit more alongside lime peel and a bit of light tartness, likely coming from both the lime juice as well as the lactic acid bacteria used in fermenting the beer.

Mouthfeel: Very light and fairly effervescent while still being a bit chewy, likely as a result of the significant adjuncts.  The main saison strain used in producing this beer is the Yeast Bay's Wallonian Farmhouse, and it's possible that this yeast produces a good amount of body-enhancing glycerol, much as Wyeast French Saison (WY3711) does.  The glycerol produced by that French Saison strain is also mentioned in his talk discussed above.  Even with the chewy mouthfeel, the beer finishes quite dry, as well as faintly tart.

Overall: I'm quite happy with this beer, and it's been a great summer drink, especially filling pint mason jars of it as "growlers" to drink on the Metra train on the way home from work.  (Yes, one of the perks of my commute is that Chicago's Metra commuter trains allow alcohol.)  In terms of improvements, I definitely think this would be better with increased carbonation and a more-lasting head.  The carbonation is just right early on, but seems to fade after the glass is initially poured.  I'd prefer to have a bottle conditioned version that hits above 3 volumes of CO2.

Aside from the carbonation issues, I'd also plan to use just a bit more lime zest next time, as that should help the aroma pop a bit more.  I think that the lime juice that was used appears in the flavor, but doesn't come through too much in the aroma.  The bitterness and mouthfeel (aside from carbonation) are where I want them, so I probably wouldn't change much there.  I would also maybe dry hop with around 2 ounces per 10 gallons of Sorachi Ace to give a bit more additional aroma (maybe the additional lime zest could also be added here?).

Demeter Vert (Batch 03): Recipe

This is my third time going through this recipe, which is a blonde saison that includes lime zest and is hopped with Sorachi Ace.  This is my first time adding in a bit of fresh lime juice as well, hoping to get a little more acidity early on without resorting to bacteria.  

Half the batch will be getting a pitch of straight Yeast Bay Wallonian Farmhouse (2nd Generation) and the other will also be getting the same second generation plus a nice blend of Brett variants (plus a few other saison strains mixed in an older cake).  The portion with only the Wallonian will serve to test something I've been curious about, which is whether my plastic buckets are now just harboring all sorts of Brett and bugs.  I'm thinking yes, as I've had cross-contamination on other saisons using loose lids, but so much so that I thought it was in the buckets.  

This isn't something I'm shying away from, as I'd love for the buckets to develop a bit of a house culture similar to how oak barrels do.  I've been using hard-bristle brushes on the buckets, so expect there to be plenty of places for the bugs to get into.  Likewise, I've also been just spraying with StarSan rather than soaking in mixed solution.  Generally, I don't want to be dirty, but I would like a little rustic character.  Eventually, I'd like to get to the point where I've got a larger temperature controlled shed or portion of my garage where I'll have barrels and beams that are littered with Brett and other bugs, with house character developing.  

I go back and forth on exactly how to best achieve the results that I'm looking for (clean primary then finishing with Brett, mixed fermentation throughout, blending clean and Brett/wild) and have so far been experimenting with different methods.  Eventually, I'd like to nail down a house process.  As of now, I'm thinking my preferred route is fermenting with a mixture of saison yeast and Brett, and then blending in wild/sour beer when I want some acidity, as that's worked out quite well with my "Science & Art" series.  (Tasting notes for #1 here and #2 here, with notes #3 coming soon along with reviews from the TalkBeer Homebrew Competition (Saison).)

Demeter Vert (Batch 02): Recipe


RETRO: Post written on November 13, 2014, but set to publish on the date of the original brew session to maintain order within the blog.

This was my second batch of what was then known as Sorachi Lime Saison.

The recipe for the full batch is as follows:

Batch Number: 43
Brew Date: June 23, 2012
Bottle Date: Not recorded
Batch Size: 5 Gallon
OG: 1.061 (estimate)
FG: 1.002 (estimate)
Fermentation Temperature: 65-70*F (room temperature throughout)
IBU: 31.8
ABV: 7.6%
SRM: 4.2

Mash: Single infusion at 149*F for 60 minutes

Boil: 90 minute

Fermentables

8lb 0oz Pilsner Malt
2lb 12oz Wheat Malt
1lb 0oz Rye, Flaked

Salts & Water

At this point I wasn't doing anything besides filtering the water and adding 5.2 buffer, so that's probably it.

Hops

1.0oz Sorachi Ace (pellet, 10.7 AAU) at 20 minutes
1.0oz Sorachi Ace (pellet, 10.7 AAU) at 5 minutes
1.0oz Sorachi Ace (pellet, 10.7 AAU) at flameout

Other
Whirlfloc
Yeast Nutrient

2 Tbsp Lime Zest at 5 minutes

Wyeast Belgian Saison (WY3724) (1 package)
White Labs Brettanomyces Claussenii (WLP645)

Notes

06.23.2012 - Brewday. Efficiency still seems low based on the OG. Not sure what the issue is. For yeast, used 2-month-old packs of 3711 and 3724 plus a good bit of Brett C slurry from the continuous jug. Hoping to create a house culture to use with different saisons. Can eventually blend in other yeast cultures if necessary, using dregs from favorite bottles.

07.28.2012 - Added the dregs from a bottle of Batch 6 Russian River Sanctification.

Notes

At the end of the brewday, I had a Russian River Batch 5 Sanctification, and added the dregs from that to the carboy.

Fementation: Ambient temperature in a 6-gallon Better Bottle. Liquid temperature was approximately 72-73 F.



Tasting Notes

Appearance: Pours a moderately-hazy light apricot color with a nice, fluffy white head. Nice retention with some spotty lacing on the way down and a thin collar throughout. 2.5/3.

Nose: The first whiff brings in a bit of lime and citrus plus some backing yeastiness. The Brett may not have been entirely finished out when I decided to keg this one, and it shows in the nose. I was anxious to get this kegged for our moving date, probably at the expense of having a better final product. When I brew this again, I'll be sure to give it some more time. 10.5/12.

Flavor: The taste doesn't have nearly as much residual yeastiness as the nose does. Instead, there's a mild acidity to go along with some zesty citrus character. I think it actually comes through more as lemon, likely because of the Sorachi, though lime is present as well. There's also a slight touch of pineapple character in the background. Fairly complex and enjoyable. 16.5/20.

Feel: The flavor suffers because of the feel. The body is nice; it's quite light and crisp with minimal malt presence in the background. There's a light zest and faint acidity throughout. However, there's not enough carbonation. I let this one sit at 12 PSI for awhile, but that didn't quite give me what I was looking for. I'm coming to the conclusion that I probably need to start bottle conditioning saisons rather than just kegging them. One of these batches I'll need to split the batch by carbonation method and see the differences. With all that said, I really love the faint acidity and citrus character to the background, so probably no change in the recipe, just carbonation. 3.5/5.

Overall: I think this could be a much better beer if I were to give the Brett enough time to really work, and also boosted the carbonation up quite a bit, hitting somewhere around 3 or 3.2 volumes. I'd also boost the lime presence just a bit, probably to around 3 tablespoons. The hops are good where they're at. I think this could end up as a very nice beer with some minor improvements and/or changes in technique. 7.5/10.

Score: 40.5/50
