PhiLambic Solera: Pull #1 tasting

I am repeating myself here but Its has been a painstakingly long wait to try the first bottle from my newest Solera. I decided to bottle the first pull straight so that I could get an idea of how things were going and determine what I would want to change for the top off batch. When I tasted the uncarbonated beer at bottling I was concerned it was a little bit one dimensional, especially because I believe that blending is so crucial with mixed fermentation beers. But I decided to stay the course so I could get to know this Solera from grain to glass.
Oh its clearly very clear.
Lambics are usually hopped with 3-4 ounces/5 gallons of aged hops while I used 2 ounces of semi-aged low alpha % hops for 8 IBUs, so I was a little concerned the initial batch may have been underhopped. Its not that I was concerned about the bitterness level but aged hops add a funky rusticity to the finished beer that I felt this could be missing. It is quite sour, bordering on being too sour but that may be because its lacking in some complexity to balance it out. Overall this is a really nice sour beer and a nice start to this Solera, I look forward to making some tweaks to the top off batch to add some complexity and round it out into a more finished product. Some more detailed tasting notes below.

Under the stress of bottle conditioning Brett does some wonderful things.
PhiLambic Solera Pull #1 - 2014

Very clear Golden yellow, moderately high carbonation tiny bubbles shooting up from the center of the glass. The head last for a while but very thin just around the edges of the glass.

Fruity forward aroma, a little bit Apple, light Funk in the background, lactic acidity. No hops or malt. A slight ethyl acetate aroma as the glass warmed to room temperature.

Tart right upfront, Lightbody, somewhat prickly carbonation. It's dry but has a little bit of a sweet bite on the back of the palate, finishes quick off the tongue leaving you with a dry puckering mouth. It is pretty refreshing and drinkable.

When I tried to first bottle of this almost 2 months ago I thought it was little bit one dimensional, and maybe lacked some complexity but its really coming along in the bottle. This reminds me a lot of Brian Hall's Lambic with a lot more carbonation. It's fruity in the nose very little barnyard, tart, dry and refreshing. It might be lacking a little bit of complexity but i think as an unblended product it holds up well. I let some of it warm up to room temp to let it open up a bit and there is a slight ethyl acetate aroma, it is very slight but something I will want to keep an eye on as the Solera ages. I am quite pleased with how this is drinking and look forward to seeing how this ages over the months to years.

Tasting Notes: Gueuze Blending 101

I have been repeating this more and more recently, but I think it is very difficult to brew a world class sour beer without blending (or aging on fruit which I view as a form of blending). There are just too many variables outside of the brewers control once you pitch your bugs, so to keep some consistency, or add complexity, we blend. As I mentioned in the Gueuze Blending 101 post I didn't have enough vintages of Lambic on hand so I chose to use commercial Lambic bladders for extra components for my blend. It worked out even better then I could have imagined, hard to completely screw up with Girardin and Beersel lambic in your blend. I learned a few things for next time and ended up with a unique "Gueuze" that I feel will age for years to come, but time will tell as these bottles of (I'm now calling) Gooz 101 age.

I sent a bottle each to my fellow Yeast Bay Beta testers Brian and Marshall. They each posted tasting notes and reviews on their blogs, Brian's ReviewMarshall's Video Review. I agree with a lot of both these guys say about the beer, from the complexity to the sourness and the distracting sweetness on the back end both Marshall and Brian hit on similar notes I have.
I moved, and the DSLR is still packed away.
At least its not that tired window again.

Like Brian said, this beer is sour, and not in a tart and then off your palate type of way, this sourness packs a punch and evolves as it hits your tongue then pierces the back of your throat. Its very complex, with some classic funky aromas and peachy/mango undertones, and a very subtle acetic character but most of the sourness is lactic. 

The only thing that is holding this blend back is that silly, awful, borderline offensive, 1 year old Turbid Mashed Homebrew component of the blend. I get all the same distracting aromas and flavors in the Gooz 101 as I do from that component. So if I learned one lesson here, and Brian touched on it in his post, is you really cannot hide a less than stellar (kind of crappy in this case) beer in your blend. I do think that the residual sweetness that this component added will age out, and help to increase the carbonation level as it is a touch low still. But I worry that the acetone/nail polish remover aromas may not transform, but that might be me being paranoid. Overall I would call this a successful blend, and I am passing judgement on a very young beer at only 4 months in the bottle. Full tasting notes below:



Tasting Notes:

Appearance: Deep dark yellow color, pours with a 1 finger bright white head that dissipates quickly to a thin ring around the sides. Fairly high carbonation, maybe slightly less than to style visibly.

Aroma: Musty funk, some acetone, underlying fruit aromas, mango and peach skin.

Taste: Sharp sourness upfront that hits the side of your cheeks and then a little stab at the back of my throat as it goes down. Prickly carbonation that gives the appearance of some body, it's bright, tart and drinkable.

Final Thoughts: This is a really nice blend, but like Brian said that one component of the blend probably should have been left out. As the glass warms I get a bit of that sweetness that 1 Year Turbid Mashed component had on its own. I believe that will age out a little bit over time but at the moment it gets somewhat distracting, more so as it warms. If not for that I wouldn't have much to complain about, only nitpick. My goal here was to learn something about blending, and I think I achieved that goal and ended up with a great little beer here. Don't hide your shitty sour beer in your blends, seems to always find its way into the finished product.

Side Note, that 1 Year Old Turbid Mashed Lambic still tastes like shit, but I have been racking about a quart of fresh hoppy Saison into it over the last few months. I'm hoping to blindly blend down that sweetness, acetic character, and acetone. I dont have high hopes that it will work, but its worth the shot, that Turbid mash was too much of a bitch to give up on it so soon.

Tasting Notes: FarmWards

I am pretty critical of all the beers I brew but especially so for Saisons. I think its quite easy to brew a passable Saison but difficult to brew a great one. This beer would probably lean towards the passable end of the spectrum, not to say that it isn't enjoyable but it leaves me wanting a bit more. Unlike my HopHands clone where I had the inside track on some elements of the beer, this was always a bit of a shot in the dark at "cloning" Tired Hands flagship SaisonHands. As I documented in the brew day post, I knew the ingredients, except for the Saison yeast, but the grain proportions and hopping were a bit of a guess.

The finished beer was much better fresh then it was after a handful of weeks in the keg. As it aged I think it showed some flaws that I didn't love. After 2-3 months it was showing a bit of astringency that I hadn't noticed before. I have a couple hunches, one including the hopping rate, but at generation 4 I am wondering if my Wallonian Farmhouse pitch is showing some age. Either way I will be buying a new pitch shortly. 

First batches of a recipe are rarely going to be perfect, and I really enjoy dissecting these recipes and working out what works and what does not. Its a great way to test your skills as a brewer, as I am learning while still trying to dial in a wheaty DIPA. I will get this one dialed in yet.
A cloudy, young, citrus forward pour by the window.
Became brilliantly clear after 3 months in the keg.

FarmWards

Appearance: Golden color, similar to the Golden State Warriors yellow. Frothy white head, 2 fingers worth, so much lacing on this glass.

Aroma: Earthy, hay like, Coriander or some kind of spice I can't pinpoint. Citrusy, subtle lemon, mango, fruity citrusy esters abound.

Flavor: Dry, spicy, yet a creamy mouthfeel that then punches you in the top of you palate as it finishes super dry and spiced, a bit astringent on the finish.

Final thoughts: This beer is pretty solid, if I wanted to call it a clone I think maybe Wallonian is a bit too different than what TH uses. But I really love the profile of this yeast, and it pairs well with Cascade, it may be hopped a little bit too aggressively but when fresh it was enjoyable. A solid recipe that needs some tweaking. 


The version with the Tire Hands Emptiness culture is going to be great with this base, I racked it onto some Chardonnay soaked oak and bottled it all up not long ago. Not sure what yeast are in the Emptiness series of beers t but it was showing an copious amounts of passion fruit in the aroma reminiscent of beers I've brewed with Nelson Sauvin.

The Yeast Bay Beta Testing: 100% Brett Pale Ale (It's not a sour Bro)

Four Carboys, one mini-fridge.
The second round of Beta testing for The Yeast Bay is the one I was most looking forward to. The four strains we tested in round one were all Sachromyces Saison strains used in the split batch Les Quatre Saisons, all very unique and a great learning experience. For this round Nick sent us 4 new strains of Brettanomyces that he has isolated and built up for us. In my opinion the tide has shifted, brewers are no longer content with only 3 strains of Brettanomyces available in pure culture, especially with a seemingly infinite selection of Sacchromyces strains to choose from. The Yeast Bay are doing their part to grow the library of available Brettanomyces cultures and I am happy to be a part of it. Maybe one day we will be free of the "Brett beers are Sour", or "Brett is always funky", stereotypes because Brettanomyces can be oh so much more than just barnyard funk.

We set the experiment up similarly to how we did Les Quatre Saisons, we would all brew the same recipe with only small variations in both mash and primary fermentation temperatures. We were each assigned a mash temp, and a primary fermentation temp range so that Nick could get a feel for how the strains work in a slightly varied wort. This time it was decided that we would keep the mash temps within a more typical range of 150F-152F, as opposed to the 148F-156F range we employed for the Saison. We just felt that there was more to be learned from the fermentation temps then the vast differences in the mashing temps.



No rubber bands were harmed
in the making of this beer.
Nick sent us some healthy vials but we all decided to get them going in some starter wort in advance of brew day anyway. The brewday was uneventful, in a good way, I mashed at 151.1F (0.1 above my target temp of 151F), chilled the wort and pitched each culture into its own ~3 gallons of wort in 3 gallon Better Bottles. Prior to pitching I aerated each carboy with only 15 seconds of pure o2, on normal batches I would aerate longer but I fear the acetobacter monster. As fate would have it, all 4 Better Bottles fit snugly into my little fermentation fridge, so a consistent fermentation temp of 71F was maintained throughout.

I took gravity readings and samples to taste at 8 weeks, preliminary tasting notes are below. I was comfortable with the gravity each one was at, but since we don't know the true attenuation of the strains I decided to let them ride a bit longer, then life got in the way and they rode longer yet. All told they spent just under 3 months in primary before I packaged them, that may seem long and maybe it is but I've went that long with 100% Brett beers in the past without issue (never for a sole Sacchromyces ferment however, unless you like the taste of burnt rubber). I am glad that I waited though because the gravity moved at least a point (3 points for 2B)  by the time I packaged, these Bretts were working for a while.

Fermentation went as expected, all four strains kicked off in the same amount of time with very little lag times. I brewed at 6am and pitched the yeast mid day after I let them cool longer in the fermentation chamber, all four showed activity within the few hours before I went to bed. There was noticeable activity for up to 5-6 weeks with some small tiny bubbles shooting up, especially in strain 1B which seemed to the most active the longest, and the numbers show.

8 Week Samples with Tasting Notes:
There's that window shot again, real original Ed.

  • Strain 1B- 1.007 the most clear. Lactic acidity, fruity nose. Stone fruits, sweet tarts, dry, pepper in background. Really awesome.
  • Strain 2B- 1.014 woody funk, cedar!, subtle acetic nose. Sweet upfront, medium body, light tartness, fruity with a bit of spice on the back.
  • Strain 3B1.013 body odor, sweaty aromas but not overpowering. Candy like tartness, a bit sweet on the back.
  • Strain 4B1.014 earthy, dirt, wood-y nose. Earthy, woodsy, some malt balance not in others.

All four seem to run the gamut of Brett flavors/aromas, some really unique stuff from the early tasting especially with strains 1B and 3B. But I would think that they will vary by the time I do a final bottle conditioned tasting next week. Below are the final numbers for myself, Marshall, and Brian, you can look forward to tasting notes and more info from them on their blogs. You can see how much each strain dropped over that last 4 weeks or so from the samples I pulled above.



Where some of the Saison strains we tested last were hit or miss I think all of these Brett strains are a hit in one way or another. Now I cant be certain until we taste all four in their final state, but the early tasting notes have me optimistic. As of this posting they have been in bottles for ~3 weeks so I will get to tasting shortly, we are all really excited about these strains. I will leave you with a slide show of fermentation and pellicles, really only 2B had a cool pellicle but its very wild looking (probably because it was the only one with an orange carboy cap).

Barrel Aged Saison: It's All Gravy, Delicious Gravy.

Crushed Sunflower seeds, absolute bitch to crush.
It's been a while since i updated on the barrel aged beers, with Barrel #1 we have already aged the Philly Breakfast Stout  and the Quad (tasting notes coming soon), both beers holding a fair amount of oak and whiskey flavors, but the whiskey aromas are waning. I have been a bit anxious to get some Brett into this barrel and felt it was about time to get going, a nice Saison with some fruity Brett strains seemed appropriate. I am a still a bit concerned that there is too much whiskey flavor hanging in there but we will monitor it and hopefully not over do it, I certainly do not want whiskey overpowering this beer.

We came up with a recipe that wasn't too high in ABV but something that packed a punch and can withstand the flavors/aromas that we will be pulling out of the barrel. I had a few pounds of Malted Sunflower seeds that I used in a very floral delicate Saison a while back, they add a grainy-ness to the flavor of the beer, and help to add body so we tossed a bit of them into the grist. The base grain was Pilsner malt of course, with some White Wheat, Naked Golden Oats, and Munich for some malt complexity, finished off with Turbinado for dryness and because we are snobs.
Frothy, fruity, funky starter of
the Beersel blend.

A fruity, tropical, Brett barrel aged Saison needs Nelson Sauvin if you ask me, we bittered with Magnum and late hopped the beer with Nelson at 5 minutes and flame out. Going into the barrel this thing was more Nelson forward than I could have hoped for, which is great because we want it to hold up for a few months in the barrel.

I distributed some Wallonian Farmhouse slurry (and some Sunflower seeds) to the group, four of us each brewed 5 gallons again with portions of each racked to the barrel and some not barrel aged. On barrel fill night we sampled each of The Yeast Bay Brett blend beers I brewed to decide what blend would be best, the group favored the Beersel blend over the other two so I built up a starter and added it to the barrel. I may have thrown some Brett Brux Trois dregs into the starter as well! 

There was a bigger difference in all of our beers going into the barrel then we have experienced in past group barrel projects. One was a bit more astringent, another was darker then we expected, another was lighter and way more Nelson forward (was awesome actually). I kind of like the variability in the batches, its interesting having each brewers own stamp on the portion being blended in and see how it all comes together in the end. There were aspects of each that I liked, or felt the Brett would enjoy working on, pretty excited for this one to finish. Now we wait...

We share 'round these parts: Lambic via Brouwerij-Chugach

The entrance to Brouwerij-Chugach.
The other week I had the pleasure of enjoying a few of Marshall's sour beers , and to complete the trifecta on The Yeast Bay beta testers tastings I was granted the opportunity to try some Lambic brewed by Brian from brouwerij-chugach.com. Brian was actually the one who started our little cross country beer sharing thing here. He reached out to Marshall and I and said he would be sending us some bottles of his beautiful Lambic. Who in their right mind would not be excited about an email like that, come on.

Brian and I share a lot of similar views on Farmhouse brewing and the sense of place you get from the house character of someones mixed fermentation beers, and food. Since Nick "introduced" us we chat regularly about all things beer and baking, bouncing ideas off of each other etc. Brian's site is new but already has a wealth of information on mixed culture fermentation practices and bread/pizza baking. He has become a mentor of sorts for me when it comes to baking bread and pizza, I went from making some mediocre stuff to blowing my own mind, he even sent me some of his leaven to get me going.

But we are here for the Lambic, and it comes from his rustic cellar from which , I imagine, many a bug thrive. Brian adheres to most traditional methods of wort production/and sour beer aging, turbid mashing, aged hops, and barrels upon barrels are used to create this LambicI would love to visit and get a tour, but unfortunately its quite a drive to Maine from Philadelphia. Who knows, maybe I will get a chance to try some of these commercially some day :) But for now I am perfectly happy receiving bottles of Lambiek Zomer in unlabeled bottles, you should be jealous.

Lambiek Zomer

Appearance: A brilliantly clear straw yellow color, very minimal carbonation as is appropriate for an unblended Lambic. Thin white head that dissipates pretty quickly.

Aroma: More fruit than funk, the funkiness is very subdued, I get a fair amount of stone fruit with a hint of lemon, some toasted malt aromas even. 
Picture courtesy of Brouwerij-chugach.com, because I
neglected to snap a photo that did this beer justice.

Flavor: Nicely tart, but not mouth puckeringly sour. There is a nice sweetness that cuts the sourness just as it starts to pucker, a good balance of fruit and sourness going here. 

Overall: This is a very well balanced unblended Lambic, its actually pretty impressive how balanced it is with it being, obviously, unblended. It can be difficult to get those bugs to do what you want, not saying that balance is what Brian was going for but its a difficult thing to nail on these beers, thats just the nature of mixed fermentation. 

It is certainly to style as far as unblended Lambic is concerned, I've only ever had one commercially and it was at Brasserie Cantillon pulled right from the barrel. Brian's version is much more fruit forward than that of Cantillon where the funkiness was more dominant, which I am sure varies barrel to barrel. This stands alone very well for me though, but would be a great blending component as well. Its not overly sour (which I've had issues with) although some sips I took I did want a little more pucker I think that the balance is what makes this pretty special. Great stuff Brian.

We share 'round these parts: the Brulosopher's bugs make it to the east coast.

If you follow the blogs Brulosophy and Brouwerij-Chugach you'll notice that the three of us have been sharing some beers with each other lately, particularly "sour" beers. Marshall, Brian and I have been working together this year as Beta testers for The Yeast Bay (thanks to Nick for introducing us!) throughout the process we have all been keeping in contact and sharing brewing (and baking) notes on both Beta testing rounds and general beer stuff a like. We all have a slightly different style when it comes to brewing, Brian and I share similar mixed fermentation obsessions while I stray into the hoppy spectrum at times his cellar is a veritable Colosseum of bugs. I will get to Brian and his Lambic in a later post.

Marshall's, aka the Brulosopher, is one of the most methodical, organized, and process driven brewers I have come across. His penchant for simplicity and optimization should both be admired and imitated by beginner and experienced brewers alike. I have adopted a few of his practices of late, specifically the Brew/Dad life balance type tips. He is doing some great things for the homebrewing community on his blog by dispelling myths and proving/disproving theories via his ExBEERiments Series. You might call him a mythbuster of sorts...

Marhsall sent me three beers, two Flanders Red's from a split batch he did with Wyeast's Roselare and WLP655 Belgian Sour Mix, I love a good split batch comparing yeast so thats right up my alley. He also sent a Funky/Sour Blonde Ale using Roselare as well, more on that one later.


Flemish Red - Roselare

Appearance: Deep mahogany reddish color, thin off white head leaving a small ring around the edges. Leaves decent lacing, but very significant legs on this one, almost like a big red wine. Steady carbonation shooting up the sides of the glass.

Aroma: Caramel malts on the nose, no acidic like or Brett aromas present. There is something that reminds me of fall, I get a really unique Squash note, by nose alone this is a Thanksgiving dinner drink.

Flavor: Nicely tart, almost surprised me actually. It's tart on the front of the tongue and on the sides of the mouth there is a pucker, right over the tongue it's smooth and silky then finishes with a maltiness to cut the acidity. 

OverallI wish that there was a bit more malt left to this beer, it would cut the acidity a little bit and make for a much more enjoyable drink. The pucker finish on the back sides of the mouth don't really make you reach for another sip quickly, not that its a chore to drink but its a sipper. In the end the beer is defined by its sourness and really nothing else. Its one of those that you have you're thinking "Damn, this is so close.", being close is a success if you ask me.

Flemish Red - WLP655
Appearance: Basically the exact same appearance as the Roselare batch. Deep maroon reddish mahogany. Thin off white head, legs similar to the Roselare on the side of glass when swirled.
AromaToasty bready malts, Carmel, dark fruits, raisin, dates. More intriguing than Roselare batch.
FlavorModerate acidic note upfront, then the malt hits the middle of the tongue, just as you think the malt is there to stay the acid takes over again in the finish with a soft subtle pucker. Some dark fruits and sweet malts mingled in there, much more in balance than the Roselare.

Overall: This was great, slightly tart that balances well with the malts. Some dark fruits, no acetic character (which I hate), no oak or hop character. I like a little oak in this style but that's just a personal preference. This one far exceeds the Roselare, and is a pretty special beer on its own.

I really enjoyed trying these two beers side by side, its always amazing how different a beer can be a variation in yeasts/bacteria pitched. I was pretty surprised that the Roselare was as sour as it was, I am not sure if it was a repitch but I had always heard that the first pitch of Roselare was a but under whelming on the sourness but would increase in subsequent pitches. I really like how WLP655 accentuated the malt and the dark fruit notes while balancing it out with the acidity, pretty great beer.

Funky/Sour Blonde - Roselare

Finally we have the Funky/Sour Blonde, which unfortunately was a miss for me. But some of the characteristics I experienced reminded me of a sour I brewed a few years ago. I emailed Marshall, and talked to Brian, to see if my notes were in line with what they had from this beer and they were not similar at all which leads us all to beleive I caught a bad bottle. I thought about not posting the notes on this beer because its obviously just a bad bottle and not what he had intended but Marshall thought it would be a good talking point, and I agree. My guess is some sort of oxidation, as the color is significantly darker than what Marhsall and Brian (link to Brians tasting notes on these beers) had experienced with this beer, paired with some cardboard and soy sauce aromas and a sweet almost under conditioned finish. 

Appearance: More amber than blonde, I wonder if there was some oxidation issue here, I've had some funky beers get dark bc of oxidation. Decent amount of tiny bubbles shooting up the glass and a small ring of head settles on the edges once it all calms down.
Aroma: Soy sauce? and malt, some cardboard, raisin, figs. I would say caramelized Figs and Raisins with soy sauce drizzled over them. Something weird going on.
FlavorSlight dryness on the tip of the tongue gives way to a sweetness that's distracting, similar flavors to the nose. It almost tastes like a beer that was only bottle conditioning for a few days.

Overall: I think something went wrong with this particular bottle. There wasn't any real sourness to speak of, it was not overly funky either, but the soy sauce and sweetness might be overpowering any of those characters. 

Ive experienced this type of discoloration in some mixed fermentation beers, and I know some other folks have as well. If anyone has some insight on what the cause could be, again I'm guessing oxidation, chime in.
