The Great EBY Brett Experiment: Round 1 Tasting Notes

A group of 12 of us met on December 19th in the back room of KnB Wine Cellars to taste the first round of bottles for the Great Brettanomyces Experiment. We had a very ambitious goal of trying all 20 strains in one sitting. It wasn't the optimal way of doing the tasting, but really the only practical way when trying to get 12 tasters together at one time (the free beer helped). Our palettes were definitely fatigued by the end and I think the ideal situation would be 2 sessions on back to back days if you want to taste all 20 strains. We had a nice mix of craft beer enthusiasts, BJCP judges, and sour/wild beer homebrewers. Well enough about the tasting lets get to the results.


Results:
These tasting notes and rankings were summarized from all the tasting participants.




Conclusions:
I think this experiment was a success (and we will continue to see how it goes). The base recipe really let the yeast strains shine (or not) while still providing enough substance to make the drinking experience enjoyable. I plan to use these results not as a these are good strains and these are useless, but as guidance to what beer styles or situations they may work well in.

Next Steps:
I'm going to follow-up in a couple different ways:
1. All the strains are going to get a second chance as a bottle conditioning yeast in a recently brewed Beire de Garde.
2. I'm going to create some custom recipes based on the flavor profiles of my favorite strains. I'll probably end up blending most of the strains together based on their flavor profiles.
3. I will also be compiling the results others are logging on the Google Form to compare and get a better idea of each of the strains

As always let me know if you have feedback or questions. We will be holding another tasting in a couple months, so let me know if you are interested.

The Great EBY Brett Experiment: Brew Process and Bottling

This post was months in the making, so I'll do my best to keep it edited (Background info here). I tend to lean towards pictures for most of my explanation as I work better that way. And most of the focus for this post will be about the organization/logistics of a complex fermentation experiment. The brewing of the beer was uneventful.






I received the Brettanomyces strains from Sam at Eureka Brewing on August 29. They came in 1.5 ml vials that were all sealed with wax tape. All of the vials, but one were completely full. The one vial that leaked still had some starter liquid left in it (and eventually took off).
09/13/13 - The first step was to get a starter going to build these yeast up to pitchable quantities. I came up with an idea to do this very inexpensively. I used plastic water bottles. The bottles are probably already sanitized, if not sterile (I still soaked them in sanitizer) and the screw tops can be manually loosened to release CO2. I labeled the bottle and each cap with the EBY #. I filled each bottle with 2 oz of 1.020 wort, sanitized the outside of the 1.5 ml vial and then poured the vial into the bottle. I closed the cap and gave each a good shake.
09/24/13 - There was already obvious yeast growth that could be seen on the bottle of each bottle. No krausen that I can remember. Each bottle got 4 more oz. of 1.030 wort. The caps were burped each morning and I never had any issues with too much pressure.

09/30/13 Brewday -
Belgian Brett Single

I decided to stay with my plastic water bottle method and purchased 1 gal water bottles with a screw cap. They cost me $0.89 each and I was able to use the water for this batch (I prefer soft water for my Saisons/Pale Sours - see profile below). This also worked very well as it was cheap and I can just recycle the plastic bottles and not worry about cleaning them or future contamination. (I don't need 20 stoppers dedicated to sours - and yes they become contaminated). The bottles were also burped everyday for the first week and every 2-3 (couple of two-tree) days after that. I definitely noticed a difference in lag time, fermentation vigor and pellicle formation between the strains. (One bottle got destroyed so I used a 1 gal glass container, which I then forgot to put on an airlock, sorry EBY 048 you got acetobacter bombed.)

11/7/13 - Bottling Day(s) (close to a month later) - Well, this sucked. Once I got my system laid out (see below) it wasn't too awful. I decided to only bottle 3 - 12oz bottles of each strain. I probably could have squeaked out 4, but it was pushing it. I poured myself a taster of each while bottling and then I have a bottle to taste 1 month after bottling, 6 months and 1 year. Since I was bottling I took brief notes and compiled them in the table below. I will note that a majority of these except a few tasted pretty similar.

And the first official tasting is scheduled for this Thursday night (12/19/13). So expect a follow-up post in the not too distant future.And I'll be filling out this form:

Barrel Pilot Batches: 100% Brett Beer Trials


It has taken some time for the group to decide on what to make for the second fill of our Chardonnay barrel. After we emptied the American Saison we noticed there was still plenty of oak and Chardonnay flavor remaining so the next batch will need to go well with those flavors. We are planning to eventually do a pale colored sour in the barrel, but if there is too much wine character still remaining it might over power the beer with the long contact time needed for souring. We thought a hoppy 100% brett beer would work well and really doesn't need much time in the barrel. The only issue is that none of us have that much experience with the style to jump right into a 60 gal batch. Therefore,Steven (the barrel babysitter) and I have been working on a couple pilot batches.

The first batch we wanted to build up and test that new strain of Brett Custersianus (Yes, Custer's anus) sent to me by Don at Small Place Big Brews. Steven had already planned to brew a Belgian Wit beer and both of us thought the description of ECY019 Brett Custersianus sounded like it would work well. So here is the recipe for that beer:


Recipe: Belgian Wit

Batch Size 12.0 gal         O.G.-1.057       F.G.-TBD
IBU-18.6                          SRM-5.4         ABV-TBD

Grain Bill (77% Efficiency):
11 lb Pilsner Malt (52%)
6.6 lb Raw White Summer Wheat (31%)
1.65 lb CaraRed (8%)
.9 lb Acid Malt (4%)
.9 lb Flaked Wheat (4%)

Hops:
.55 oz Pacific Jade, 14.2%, pellet, 60 min 16 IBU
.3 oz Pacific Jade, 14.2%, pellet, 15 min 2 IBU
.3 oz Pacific Jade, 14.2%, pellet, 10 min

Spices:
10 g Coriander Seed
.5 lb Crushed Kumquat
1 g Black Pepper

Yeast:
WLP400 Belgian Wit Ale - 5 gal
ECY019 Brett Custersianus - 5 gal

Mash/Boil Details:
Protein Rest. Temp/Time: 122F @ 30min
Sacc Rest. Temp/Time: 148F @ 75min
Boil Time: 90min

So that plan didn't work too well, the gravity didn't move and no change in taste for a week  We think we tried to step it up to 5 gals too quickly and didn't have enough yeast (This is a time when the brew day was planned before the beer). Thankfully Steven is an extremely clean brewer and nothing else started to ferment. At that point, we talked and decide to add some wine yeast. I've wanted to experiment with wine yeasts in beer (some good info here and here) and this seemed a good time. The wine yeast kicked in and fermented to 1.020 (it is incapable of fermenting maltotriose), so we are hoping the Brett will kick in (per Steven's last check it seems so). This might be an interesting beer that will need some time to finish out. Not sure how this will turn out, so we decided to start another batch.



We decided to go with the Brett Drie strain since I have a good amount of experience with it. The flavor profile we really want to hit with this beer is " intense juicy tropical fruit flavors in a well balanced, medium mouthfeel beer". We have picked out the malt bill to help with building body (Because Brett can't produce glycerol, which helps with mouthfeel). We also wanted some complex sugar (from CaraMunich) because in my experience that helps Brett Drie produce more fruit esters. We plan to mash a tad high at 153-154 to prevent the beer from drying out too much.

Next the hop bill, we want to hop burst this for max flavor and aroma with just enough IBUs to help balance the beer. I'm thinking around 30, since Brett seems to accentuate bitterness and we will have some "perceived" bitterness with the flameout and dry-hopping. We are thinking of a blend of hops:
  • Belma for its round tropical notes and it's cheap ($5/lb when it was available)
  • Citra for the melon notes
  • Nelson for the passion fruit (matches well with the esters from Brett Drie).
I found both Citra and Nelson in bulk, so we'll have plenty when we step it up to the barrel. I got them from Label Peelers, which also had some Amarillo and Mosaic so those will find themselves in some beer soon. I'm think of making a series of single hop pale ales to have on draft. I'm think they will be super short brew sessions with extract, a 15 min boil, and lots of late hops - my goal is to brew under an hour.

Recipe: Hoppy Brett Beer

Batch Size 5.0 gal         O.G.-1.065          F.G.-TBD
IBU-33                          SRM-7                ABV-TBD

Grain Bill (77% Efficiency):
2 Row Malt Grain 8.000 lb
Wheat, Flaked Grain 2.000 lb
Caramunich Malt Grain 8.000 oz 56 L
Oats, Flaked Grain 16.000 oz
Acid Malt Grain 6.000 oz

Hops
2 oz Belma 9.8% -15 min 23 IBUS
1 oz Nelson Sauvin 12.5% - 5.000 min 10.2 IBUs

Whirlpool
0.5 oz Nelson Sauvin 12.5%
0.5 oz Belma 9.8%
0.5 oz Citra 12.0%

Dry Hop
0.5 oz Nelson Sauvin 12.5%
0.5 oz Belma 9.8%
0.5 oz Citra 12.0%

Yeast:
Drie Brett

Mash/Boil Details:
Sacc. Rest 153 F

As we I'm writing this, we just decided to make this a 10 gal batch and try the Alchemist's Heady Topper, Conan yeast that Derek at Bear Flavored Ales sent me recently.

I'll post tasting notes of the two pilot batches soon.

Homebrew Tasting: Chardonnay Barrel American Saison

Barrel Aging is worth it. This beer is easily one of the better homebrews I've had. I have done other oak aged beers, but this is the first barrel aged. It is hard to nail down exactly what is different. I think it just tastes more "finished". The flavor complexity is there, but it is subtle and makes the beer easy to enjoy. I ended up sharing a couple bottles with a wide audience of beer drinkers and it was universally liked. The hardcore beer drinkers could pick out the individual flavors (as discussed in detail in my tasting notes) while the novice drinkers thought it was "smooth" (a description I hate, but translates into the flavors meld together well).




My detailed review using the BJCP Score Sheet:



We are still deciding on the next brew for this barrel, but we are leaning toward a pale beer with lots of tropical hops and 100% Brett Custersianus fermented (thanks to Don at Small Place Big Brews).

Barrel Project: Bottling Chardonnay American Saison

It has come time to bottle our American Farmhouse Chardonnay Saison. We were expecting a pretty quick turn-around on this barrel for a few reasons:

1. This was a fresh Chardonnay barrel and we didn't want too much flavor extraction
2. A Saison with Brett does not need the extended timeline as true sour beers with bacteria. The Saison yeast is capable of fermenting a large portion of the sugars, which reduces the rick of the Brett over-carbing the beer once it's in the bottle. (This beer finished at 1.005)
3. We are going to cork and cage the beer - so high carbonation is just fine.


The difficult part about these projects is communication. Our group has used an email thread to organize who is bringing what and discuss ideas on the best way to accomplish the task. One thing that we learned from this process, is that with 6 people trying to communicate it is difficult to keep up with the all the information. With our group there ended up being confusion on how many bottles we needed and who was bringing bottles. So tips for next time:

  •  Create a Google Doc or Forum so the ideas and tasks can be better organized
  • Have 1 person get all the ingredients 
  • Start getting the ingredients several weeks before the bottling session (we had a tough time finding appropriate Belgian beer corks locally and even online)

We decided to bottle half and to keg half of everyone's share. Below is a list of all the supplies we needed to bottle 1 - 60 gal barrel (55 gals of beer):


The other trick to this process is to get a good assembly line going. First, crack open a super nice bottle of beer like Lost Abbey Veritas 011 (thanks Chris - this also solidified me brewing a strong malty Brett beer aged with Cognac since trying Crooked Stave Sentience in Cognac)









Clean your bottles. Rinse with the faucet attachment and then the bottling tree is a huge time saver.



Get a couple people filling bottles (we used a bottling bucket and a beer gun from a keg).


Then the bottle is passed to the corker (it takes some adjusting at the beginning to get the correct insertion distance (TWSS)). Then put on the cage and give it 7 twists. (use a pencil or other round object to twist the wire)


We didn't quite get the full volume we were expecting. Mostly because we were a few gallons short when filling the barrel. In a last minute audible  Steven got some of his year old Berliner Weisse and we blended it half and half for the final 5 gals.








Expect to see a tasting of this beer shortly as I have heard from 2 of the guys that the beer is carbed and tasting fantastic. Also I have 5 gals in a keg I'm considering to mess around with, let me know if you have any ideas.


We are still working on the next beer to fill the barrel. There is still a lot of Chardonnay flavor left, so we are leaning towards a pale base and going full sour.

Homebrew Tasting: Great Saison Experiment + Extra

The Great Saison Experiment (Part 1, Part 2) went marginally. I'm not having the best of luck with my experiments lately (The Great Wood Experiment was crashed by Brett). The positive spin is that I'm learning more about experimentation. The Saison Experiment's problem was that I tried too many new things in one test. Mainly, I used a huge dose of oats in the beer. Also the lower starting gravity of the beer and high percentage of simple sugars resulted in flat tasting beer. These 3 things are my only explanation as to why these beers don't have much flavor  And without much flavor it is difficult to pick out differences in yeast. So next year, I'm going to stick with a more straight forward and tested recipe to use as the canvas for these yeasts.


There were some subtle differences, but not nearly what I was expecting from this experiment. Therefore I'm going to hold off another month on an official tasting to see if I can get some more flavor development and a greater spread between each sample. As a result of not being all that excited about the results, I ended up splitting these batches even more. Below is a list of all the beers made from this single 20 gal brew session:







  1. French Saison Wyeast 3711 - harvested from last year's French Saison - 5 gal batch
    1. Plain (1 gal) - bottled
    2. Farmhouse Pale Ale #1 (2.5 gal) - Dry-hopped with 1 oz Citra - brought to QUAFF
    3. Farmhouse Pale Ale #2 (1.5 gal) - Dry - hopped with 1 oz Chillindamos' Centennial hops
  2. Saison Dupont - harvested - 5 gal batch
    1. Plain (1 gal) - bottled
    2. Farmhouse Pale Ale #3 (2.5 gal) - Dry-hopped with 2 oz Saaz Whole leaf - drank during the Barrel Project
    3. Farmhouse Pale Ale #4 (1.5 gal) - Dry - hopped with 1 oz Chillindamos' Centennial hops
  3. Brett Drie - used yeast cake from ESBrett - 5 gal btach
    1. Plain (1 gal) - bottled
    2. Pink Version (1 gal) - 1 liter of homemade Prickly Pear syrup, 1 oz Hibiscus flowers - bottled
    3. Go-Go Juice (1 gal) - 1 lb dates, 1 lb figs - carmelized
    4. Farmhouse Pale Ale #5 (2 gal) - Dry - hopped with 2 oz HBC 342 - weak, added 1 oz Calypso - currently on tap (10/5/12)
  4. ECY03 - 1/2 vial - 1 gal batch - bottled
  5. ECY08 -  1/2 vial - 1 gal batch -  bottled
  6. Lost Abbey Red Barn - harvested -  1 gal batch -  bottled
  7. Southampton Saison Deluxe - harvested -  1 gal batch - bottled
  8. Logsdon Seizon Bretta - harvested -  1 gal batch -  bottled



Farmhouse Pale Ale
This might be my new summer beer. This is going to be brewed every year. I have never gone through kegs that fast and had so much great feedback. I took Farmhouse Pale Ale #3 (Dupont-Saaz) to our Chardonnay Barrel Project brew session and it went over very well. So well, that there was only a super cloudy pint went I got back home. Farmhouse #1 (3711-Citra) was taken to my monthly QUAFF homebrew club meeting and seem to be well liked by most. We usually don't get too much feedback about beers because the meeting is so big, but multiple people asked about it after the meeting. Then #2 and #4 were just a showcase for Sean's (Chillindamos) homegrown Centennial hops. These hops were so aromatic with a great blend of piney and lemon citrus falvors. The yeast character on the 3711 version boosted that lemon character even more.

Right now I'm working on my Farmhouse IPAs which are dry-hopped versions of my Spelt Saison.



I do have one formal tasting sheet filled out on my Brett Drie Table Saison with Prickly Pear and Hibiscus.




I'll be tasting all 8 plain versions side by side in the next month. Contact me if you are interested in participating.

Brett Drie (Trois) Overview + Spelt Saison Results

First, a confession - I have become slightly obsessed with a single cell organism.

 I have posted my experience with Brett Drie (WLP644 - Brett B Trois) (Avery 15 Brett) in a couple different online sources so I thought I would compile some of the information.

WLP644 -Brett B Trois - Homebrewtalk Thread

WLP644 - Babblebelt Thread




I have been brewing with this strain for about a year and a half. The back story is that one of my homebrew friends cultured this from a bottle of Avery 15. The yeast is referred to as the Brett Drie strain. If you have read through Chad Y's paper and website he discovered that there are actually 2 strains present (Chad still uses these strains at Crooked Stave in addition to others he has isolated). They were each used in his thesis experiment and the fermentation is well documented.

My friend, Adrian, gave me a vial and Neva at White Labs one too. It took White Lab's quite a while to come out with this yeast and not sure how well it relates to what I have been using. Did they isolated one strain or do any manipulation?)


I do know that I get the flavors and attenuation that others have reported from using WLP644. After my first time using this Brett I was hooked. The tropical fruit notes were great, they literally filled the room when I was bottling.

Best Bitter with Brett Drie -  1.048 - 1.010 - 79% Apparent Attenuation - Mashed 154 - 8% crystal malts  - 30 IBUs -no aeration - big tropical fruit - nice w/ Goldings


I have tried it in several different styles of wort since that first test batch (link above) and consider it my house Brett strain. I mostly use it in Primary as in the examples below. (I have also used it at bottling in some Saisons and was not all that impressed with the results - mostly some light traditional Brett funk flavors.)

Old Ale wort -  1.079 - 1.014 - 82% Apparent Attenuation - Mashed 154 - 7.5% Crystal Malts, 8% Turbinado sugar  40 IBUS - 8.6% - aerated - sour and decently complex in 3 months - one of my favorite beers I've ever made or tasted.

Hoppy Bitter (Extra Special Brett-er) - 1.049 - 1.006 - 20 IBUs - Dry-hopped w Nelson - testing it with a Hoppy wort - no aeration - fermentation fruit notes played really well with tropical fruit notes of the Nelson hops - my best hop forward beer I've made.

Table Saison with Rolled Oats - F.G. (.999) - 103% Apparent Attenuation. Mashed at 147 with 80% Pils, 15% Rolled Oats, 2.5% Acid Malt, 2.5% Piloncillo sugar - very clean on first taste, going to dry-hop half with HBC 342 hops (aroma and taste was weak) and now added 1 oz of Calypso hops


Aeration:
The Brett will produce some acid (acetic) if you aerate it well, the acidity is just enough in my opinion to give people the idea that it is a wild beer, but no where near a sharp bite. If you do not aerate, then the yeast will still produce the fruit flavors, but with little to no acidity and a very "clean" taste.


Fermentation:
I get a very quick fermentation from this yeast, but I'm making large starters. I usually start with some saved yeast in a White Labs vial that is 1/8 full of yeast. I do a 4 oz 1.020 starter , then a 32 oz 1.040 starter, then 64 oz 1.040 with a week between each. According to my estimates (very rough) and this calculator (http://yeastcalc.com/ - based on Sacc), I had some where around 220 billion cells. The majority of the activity seems to be done in a few days and then I get some residual for another couple weeks.











As for temperature, my first batches were all fermented in the 68 - 72 range. Well, for this most recent batch of Spelt Saison I wanted to test this temperature dependence. I split the main batch wort into 2 - 1 gal batches. One batch was fermented with a normal Saison temperature profile (start in the low 70s and free rise into the 80s and held for a week). The other batch was temperature controlled in the fermentation cabinet at 63-65 for 2 weeks and then brought up to mid 70s. The fermentation looked complete after 2 weeks.

Results: 
Saison Profile - 1.000 - nice spicy notes, Belgian phenols and light fruit notes
Low Ale Temps - 1.000 - nice spicy notes, Belgian phenols and light fruit notes

I was surprised by the results, both were 100% Apparent Attenuation and 7.9% ABV. These both were allowed to ferment out for a total of 3 weeks before bottling. I'll do an official taste test in the following weeks.

Flavor Progression:

The beer starts very clean (no noticeable acidity if you don't intentionally aerate) with huge tropical fruit flavors. I refer to the flavor as POG (Passion Orange Guava). After a month or so that flavor starts going toward over ripe fruit with a bit of funk. And long term the beer has gotten progressively more sour (I may not have a pure culture), but not more than a mild tartness. And the tropical fruit flavors remain and are mixed with more traditional Brett funk notes.

Bottling/Packaging:
Nothing to worry about if you are kegging, but for bottling I have been waiting about 3 -4 weeks. And the stability in the bottle is great. You can use standard priming sugar amounts. This Brett strain and most of them have very low flocculation. You may need to assist the yeast to floc out with a cold crash and a bit of pressure. Also gelatin and racking will greatly help.

Notes:
One thing I have just noticed in my latest Table Saison with 100% Brett is how clean the fermentation profile turned out. The beer was mashed at 148 with 20% rolled oats. This beer fermented from 1.044 down to 1.000 in about a week. I am thinking that without very many complex sugars (from a higher mash temp or crystal malts) that the Brett does not produce the same esters. Also it did not have a lot of hop compounds to play off either.

Please feel free to ask questions and suggest ideas for future experiments. (I am interested in seeing the fermentation limits of this yeast - 20% Brett Beer anyone?)
