Jester King Now Solar Powered!

14 June 2017

JK Solar-2713 (2)

We’re very excited to announce that Jester King Brewery is now solar powered! Last month, we activated our new, 78 kilowatt solar power system, which is one of the larger systems in central Texas! We have three arrays of panels that cover most of our ~11,000 square foot roof. The arrays are oriented in different directions to catch solar energy throughout the whole day. This means that on a sunny day, the brewery can run 100% off of solar power, as well as send excess power back to the grid. Finally, the panels not only create energy, they also absorb thermal heat. This means that there’s less thermal transfer into our barrel room, which makes it less energy intensive to cool to fermentation temperature.

Solar energy at Jester King is the most recent step in making the brewery more sustainable. But we still have a long way to go! For instance, we still need to develop the ability to catch our own rainwater, treat our wastewater for irrigation, and power our boiler off of biofuels and/or brewery waste. In the years ahead, we will continue to make improvements that will ultimately make us a truly sustainable brewery.

We’d like to thank the U.S. Department of Agriculture for its grant assistance in helping us fund the project, as well as Circular Energy for their help and guidance installing the system.

Montmorency vs. Balaton Blend 4 Release

12 June 2017

We’re excited to announce that Jester King Montmorency vs. Balaton Blend 4 will be released this Friday, June 16th at 4pm!

Montmorency vs. Balaton is our barrel aged sour beer refermented with Montmorency and Balaton cherries from Michigan. To make Montmorency vs. Balaton, we brew a medium gravity, pale wort with Hill Country well water, local malt from Blacklands Malt, and hops. We initially ferment it in a foudre or stainless tank with our mixed culture, then age it in neutral oak barrels for about eight to fourteen months. We then create a blend and referment it with about four pounds per gallon of cherries for about four weeks. Finally, the beer is naturally conditioned through refermentation in bottles and kegs.

Montmorency vs. Balaton Blend 4 is 6.1 percent alcohol by volume, 1.004 specific gravity (1 degree Plato), 9 IBU, and 3.4 pH. It was packaged on May 2nd, 2017. It will be released when our tasting room opens this Friday and will be available by the glass and in bottles to go. We have about 3,400 bottles available (500ml/$20) with a bottle limit of two bottles per customer per day. Outside of special events, Montmorency vs. Balaton will only be available at Jester King.


Introducing Jester King Demi-Tone

8 June 2017

LR- (2)

This Friday, June 9th at 4pm, we’ll be releasing Jester King Demi-Tone! Demi Tone is our farmhouse ale refermented with the “spent” blueberries from Jester King Colour Five.

Demi-Tone (blueberries) follows in our lineup of refermentations with spent fruit, which includes La Vie en Rose (raspberries), Detritivore (cherries), and Grim Harvest (blackberries). The result of refermenting on spent fruit is a more subtle fruit character and arguably more complexity in terms of the fermentation profile.

We’ve always been a little cautious when working with blueberries, as we’ve encountered acetic (vinegary) issues in the past, which we’ve always dumped down the drain. Some may recall our Blueberry FAIL of 2014, which resulted in a beer with some very harsh, sharp acidity. We’ve come a long way since our first attempt of working with blueberries, and we believe Demi-Tone is a really great expression of one of our core philosophies — allowing native yeast and bacteria to create interesting flavors and aromas through the fermentation of grains and fruit.

Demi-Tone was made by taking a young (1-2 month old) farmhouse ale brewed with well water, malted barley, malted wheat, oats, and hops, and refermenting it with the spent (or leftover) blueberries from Jester King Colour Five. It is unfiltered, unpasteurized, and 100% naturally conditioned. Demi-Tone is 6.3% alcohol by volume, 11 IBU, 3.6 pH, and has a finishing gravity of 1.001 (0.25 Plato). It was packaged on March 7th, 2017. It is our first ever batch.

The artwork for Demi-Tone, like all our labels, was created by Josh Cockrell of Jester King and is inspired by music theory and sacred geometry.

Demi-Tone will be available by the glass and in bottles to go. We have approximately 1,400 bottles available (750ml/$18). The bottle limit is one per customer per day. Aside from special events, Demi-Tone will only be available at Jester King. We hope you enjoy!






Introducing Jackie O's / Jester King Final Entropy

1 June 2017

LR- (1)

We’re excited to introduce Final Entropy — our collaboration with Jackie O’s Pub & Brewery in Athens, Ohio. For Final Entropy, we kept things remarkably simple and made a Kolsch inspired beer. For those who’ve been following us throughout the years, you’ve probably noticed how in addition to making barrel aged sour beers inspired by breweries like Jolly Pumpkin, fruit refermentations inspired by breweries like De Ranke, and spontaneous fermentations inspired by breweries like Cantillon, sometimes we like to brew simple, little, hoppy, dry beers for enjoying around the brewery. A visit from our good friend Brad Clark of Jackie O’s gave us a chance to indulge in this desire.

We brewed with Hill Country well water, German malted barley, and Fuggles and Saaz hops. We fermented in stainless steel with our mixed culture. One thing we’ve learned over the years is that even though all our beer contains souring bacteria, if we brew with a pretty big dose of hops, our beer doesn’t become sour, at least not for quite a while. We love sour beer, but we don’t do sour for the sake of sour. We want balanced, drinkable beer, and sometimes that means making something bitter without much acidity. Like Yvan de Baets wrote, Saison is “either sour or very bitter”, and that’s something we can influence through our hop additions.

Final Entropy is 5.3% alcohol by volume, 1.001 specific gravity (0.3 degrees Plato), 45 IBU, and 4.3 pH. It was brewed on November 21, 2016 and packaged on January 3, 2017. It will be released at our tasting room on Friday, June 2nd at 4pm by the glass and in bottles to go. We have about 2,800 bottles available (750ml x $9), and we anticipate that some of the batch will be distributed outside our tasting room. There is no bottle limit. We also will have Final Entropy t-shirts for sale.



2017 Boxer's Revenge Release

25 May 2017

Jester King-0359 (1)

This Memorial Day weekend, we’re releasing 2017 Boxer’s Revenge — our barrel-aged, sour strong ale! Boxer’s Revenge is a blend of beer fermented with our mixed culture of brewers yeast, native yeast, and native bacteria, aged in oak barrels for 8 to 14 months, blended, and naturally conditioned. It also happens to be the first beer we ever brewed back in 2010.

2017 Boxer’s Revenge, like all its predecessors, is a simple beer. It’s brewed with well water, malted barley from Blacklands Malt, malted wheat, and hops. It was initially fermented with our mixed culture in a stainless steel tank, then transferred to neutral oak barrels for long-term aging and maturation.

This year’s Boxer’s Revenge is 9.5% alcohol by volume, 1.004 specific gravity (1.0 degree Plato), 16 IBU, and 3.4 pH. It was packaged in March and is unfiltered, unpasteurized, and 100% naturally conditioned.

2017 Boxer’s Revenge will be released when our tasting room opens at 4pm on Friday, May 26th. It will be available by the glass and at bottles to go. This year’s blend is pretty big! We’ll have about 6,500 bottles available (750ml/$18). There’s no bottle limit, and we expect some 2017 Boxer’s Revenge to be distributed beyond Jester King. Finally, we’re open this Memorial Day too from 12-9pm. Cheers!
