Mini Batches

IMG_6384

It’s that time again; cooler weather in Texas brings on the lambic-style season. I’ll be brewing a second batch of Woxbic in a few weeks. In the last post I mentioned that things would be slowing down and the rate of posting shows.

Since the last post, the two batches of Saison with wild yeast fermenting at different temperatures have been bottled. It’ll be another few weeks before we have carbed bottles for tasting but the whole experience was interesting. Initially the hot fermentation produced a more sour beer, but eventually the tartness faded before bottling. The cold-side took quite a while to take off, mostly due to my lack of yeast starter. I had a huge pitch, but it wasn’t fresh. The cold side ended up much smoother in flavor profile. The hot fermentation picked up an odd flavor (not mousy, though that showed up as well). In any case, I dry-hopped both with some tasty hops and shortly we’ll have a tasting.

The whole experience of brewing 11 gallons, fermenting two batches, dry-hopping, and then bottling, possibly leaving me with 4 cases of beer that may not work out seems a bit excessive given the experimental nature of the batches.

This though has led me to work with smaller batches. In fact, one of the local homebrewers who has won NHC medals uses exactly this method for honing and tweaking a recipe. With that decided, I picked up a 5 gallon pot and a mini siphon and decided to have at it.

Mini-BIAB
I completed a 1G recipe, Brew in a Bag (BIAB) mash to reduce the number of vessels and work with the grains I had on hand rather than purchasing Dry Malt Extract or Liquid. I had hoped that this smaller batch would mean for a shorter brew night, but it was roughly equivalent.  Mostly due to the stove burner being just adequate for the 3 gallons of liquor. 20 minute strike temp, 1 hour mash, 10 minute raise to boil, 75 minute boil, 20 minute chill, plus cleanup and prep time. About 4 to 5 hours.
Stove-top Boil
The good news was all of that brewing at a larger scale translates just fine; I didn’t forget anything and I netted about 1.5 gallons (slightly under gravity target, but I didn’t want to boil any longer for fear of raising the IBUs too high). I had recently stepped up a fresh dump of Jester King Brewery yeast picked up from Jester King itself. My friend had fermented a few beers with it and was astonished at how violent it ferments at sub 60F temps.

Let’s just say, it’s still working =)
JK Yeasties going to WORK

Ill let you know how it’s going in about 4 weeks.

Notes

Mash went fine, though lost about 2 to 3 degrees with pot in the oven, preheated to 200.
Dough in should have been 160, but stirred in at 157. Ended up with a 154 strike temp and ended up at 150.

Boil was easy, probably took 20 minutes to get there from 150s. Held for 15 minutes with no hops to reduce water, added hops (60 minute addition), after 60 pulled hops, boiled for another 15, for total 90 minutes.

O.G was low (1.068) but yield was high, 1.5G instead of 1. Can't tell if I had too much water or not. Recipe called fro 3.2 gallons, and measured by weight (8.35 lb per gallon => 26 lbs of water).

Chilled in sink, accidential minor dillution. Chill time approx 20 minutes, with vigorous stirring until temp is about 117, then rested in water for another 10 minutes. Pitching temp was about 72F. Stored in 58F garage, signs of fermentation present in 12 hours.

2015-01-12 full active fermentation in full swing. Ambient 55F, infrared reading of top layer of wort about 57F.

2015-01-17 -- pull 2 oz sample. Not enough for hyrometer, so utilized a refractometer. Reading was 6.8 Brix, with no correction factor, and O.G of 1.068, this puts the S.G at 1.009. pH reading shows 3.63. Lots of barnyard funk in the nose, cloudy yellow. Taste is a bit hoppy, slight tartness, some malt flavors. Obviously green beer, but not entirely bad. Drank the whole sample.

2015-01-22 -- (Pulled from .5 gallon jar vs. 1G jar) Reading 6.5 Brix with no correction, O. of 1.068, calc says S.G at 1.08. pH reading at 3.50 @ 66.6F. Nice funk, a bit flora, less cloudy. Solid sour bit, followed by some sweet pilsner flavors, a touch grainy, subtle hopiness. Tastes really good right now. Not much oak in there, yet; might add a few more cubes and see where it is in a week.

Slow and Low

racking_whiskey_barrel_big_daddy_barleywine-1024x768

Racking 5 gallons of Big Daddy Barleywine from a Balcones Blue Corn Whiskey barrel.

This week at Woxford, we’re bottling 15 gallons of barrel-aged beer. A barleywine which spent nearly 4 months in a Balcones Blue-corn whiskey barrel will fill about 26 750mL bottles. The second barrel, an 11 gallon Rum barrel filled with Makkurokurosuke RIS will be transferred into approximately fifty 750mL bottles. The replacements have been brewed and fermented at this point; now just to swap contents and wait a bit more.

You may have noticed it’s been about a month since the last brew session. That may be more typical as the home schedule is filling up. That got me thinking about what sort of beers and ingredients I wanted to focus on given that the frequency of brewing is going to slow down. Recently we’ve been testing out new yeasts and blends and I want to see about doing a bit more of that, but with a single yeast blend. This blend includes saison Saccharomyces, some brett, and quite a bit of souring bacteria. The fun part is learning how to use both to get the beer to be just right. The tools are fairly simple: hops, temperature and time.

Larger amounts of hops will inhibit the growth of the souring bacteria. Higher temps will favor Saccharomyces, even though lactobacillus can handle and prefers high temp, sacc will out-compete and dominate. Lower temperatures, while not the best for souring bacteria, will favor a more sour beer due to the sluggishness of Saccharomyces at lower temps.

This is the hypothesis, with quite a bit of anecdotal material (in the form of really good beer) to back those assertions. But, the proof, as they say, is in the pudding. $240 worth of pudding.

750ml_bottles-1024x768

Drinking Jester King’s Le Petit Prince, 2.8% Farmhouse Table beer. Excellent working beer. Look at all of those 750mL bottles.

This recipe will be the second farmhouse sour recipe. The first resulted in solid, but not sour saison. The Farmhouse Saison Experiement still need a proper review, but the result was a bit one dimensional despite using four different strains of Brett. The effort did help confirm that one cannot kettle sour a beer in an aluminum pot beyond about 3.8 pH. Bizarre!

For this recipe, I’ll split the wort post-boil and run two different fermentation schedules. The first, will be held between 55F and 60F to simulate a brew in the winter time (Texas) where the average temperature is lower. The hypothesis suggests this should produce a more sour final product. The second half will use a more typical saison schedule, starting around 65F, holding for 24 or 48 hours and then ramping up (and/or letting free-rise) until fermentation is complete.

The final products will be compared and contrasted. I may end up blending them in the end as well. In any case, this should be pretty exciting.  Note the recipe says Wyeast 3711 for yeast, that’s the closest to Jester King Dregs, but it’s not the same (and certainly doesn’t contain the souring bus).

Hoppy Sour

I have a sour buskett.

Bucket Sour — extra wort left in an empty grain bucket. Remarkably tasty.

There aren’t too many examples of hoppy and sour; they tend not to go well together. Besides the flavor clash the bacteria responsible for souring beer (mostly lactobacillus and pediocaucus) don’t do so well in highly hopped wort. Combine this with the general anxiety and fear of introducing bacteria into non-sour/non-brett production breweries and these beers just aren’t that common.

A local favorite, Black Star Coop, hosted a “Summer of Sour” celebrating sour beers and some of the techniques used to make them. My first sour beer adventure started after drinking an amazing tasting Berliner Weiss, called Waterloo, from Black Star. I emailed the head brewer at the time, Jeff Young, about how to make Waterloo. With his information as well as listening to him talk in the Sunday Session show about kettle souring or sour worting I took the plunge. Jeff is now starting up his own brewery, Blue Owl Brewing, which will focus exclusively on this technique for making sour beers.

Black Star coop released Dr. Vainglory, which is, as they call it, a Sour American Pale Ale (SAPA). It was a truly unique and tasty beverage, carefully balancing sour with lots of tropical notes and a firm, but not overpowering bitterness on the finish. Amazing.

After securing some Meridian hops, which were used in this strain, I decided, I’d give it a try. For souring, I’m using a blend of Gigayeast’s Fast Souring Lacto, and Wyeast Lacto. After 5 days at 76F, the starter was tremendously sour, a pH of about 3.4. I’ll be pitching this combination and keeping it at about 115F for about 4 days; which should create an extremely potent sour base. From there I’ll boil, hop, chill and then pitch a large starter of Brett B. Trois to finish off the rest of the gravity.

Stepping up some “fast” sour dregs

Mmm, sour beer....

Jester King Biere de Miel dregs added to a 1L DME starter

Jester King just released new beer.  They’ve been releasing one beer after another after another and another one.  Which is completely awesome since it’s a local brewery. My favorite of the new releases is Biere de Miel which is the perfect balance of funk, tart and complex flavors. The nose is all honey sweetness and tart funk. The flavors are a tidal wave of sweet and sour; it ebs and flows as both fight for dominance. The sour wins in the end and the long, dry finish is amazing. OK, so I love this beer. Ad over.

One of the most interesting aspects about this beer to me was the timeline. On their blog post, Jester King mentioned the fermentation dates: brewed in December, 2013. It was packaged in April, and released in May. Given the level of aggressive sour flavor, I’m astounded at how quickly this beer came together. Most of my “quick” sours haven’t really panned out, as to be expected. But a four mouth souring timeline is very doable.

I emailed the head brewer, Garrett Crowell, who is just as gracious and generous with information as the co-founder Jeffery Stuffings, and asked about the IBU levels. Garrett indicated that the first batch had about 8 IBUs which resulted in the beer reaching terminal pH before fermentation was finished. Needless to say, I’m very interested in getting these dregs up and running.

After about three days on the stirplate, some initial activity showed up. I think that’s remarkably rapid growth from just what was at the bottom of the bottle.

Buzzby is a sour bee

Initial krausen forming after three days on the stirplate.

And it keeps on going. I plan on stepping this up with another 1L addition to have a large enough pitch for a friend’s 7 gallon batch of a sour English Mild. If all goes well, then this may be the new yeast I use for making a base sour saison to be used in blending.

Sour BOMB!

Full Krausen! Be fruitful and multiply!

Woxbic Update: Successful Barrel Fermentation

woxbic-barrel-fermenting-1024x768

Active Fermentation in oak barrel with ECY20 blend in Lambic-style beer

After about 24 hours since pitching, there was activity in the air lock. In 48 hours it had turned into a foam over.  I replaced the liquid once in the airlock only for it to foam up again.  Instead of fighting it, I just opened it up to the world.  The aroma coming out of the barrel was amazing.  It smelled funky and full of oak tannis.  I spent a lot of time smelling the bung of this barrel.  I immediately wished I had 10 barrels of this stuff.

I left the air lock off for roughly a week. We had a cold spell down here in Texas and my garage was an usually cool 40F.  I decided that I should use a heat belt next to the barrel to keep the temperature close 60F.  That way I wouldn’t stall the active fermentation.

woxbic-krausen-closeup-1024x768

After 2 weeks fermenting in the garage, pulled sample and it’s down to about 1.010 S.G. I’ve now moved the barrel into the house and it’ll stay at 70F for years to come.
