Riverwards IPA: brewing on a commercial scale

Ed/John, brewing is serious biz.
I recently had the opportunity to design and brew a beer with my friend, and head brewer, John Wible at 2nd Story Brewing Company in Philly. Back in April of 2014 I won 2nd Best Of Show for batch #1 of HopWards in the Philly Homebrew Cup, the prize was the aforementioned brew day. John and I have brewed together in the past and chat about hoppy beer brewing quite regularly so I was looking forward to working with him on a commercial scale.

Once I got the inevitable question of "Can we use Brett or bacteria in your brewhouse?" out of the way (the answer was "hell no" btw) we settled on our shared passion for hoppy beers and set out to build an IPA recipe. Due to contracting and limited availability its not as easy to acquire some of the trendy hop varieties on a commercial scale as we can as homebrewers. Luckily though, John already had Citra, Amarillo, and Simcoe on hand so we could run with what would essentially be batch #2 of We Talkin 'Bout PracticeI tweaked the grain bill quite a bit from that initial batch, using 10% Wheat and 10% Oats with the rest base malt, and dropping the sugar.

We blended equal parts Citra and Amarillo late in the boil, and even more in the whirlpool to achieve a tropical fruit juice character. To finish it off it was dry hopped with a 40/40/20 ratio of Citra/Amarillo/Simcoe, adding the Simcoe in for a little bit of piney complexity to keep from being too one dimensional. The end goal is a super fruity, tropical juice forward IPA with a creamy texture and a subtle pineyness. 2nd Story uses Conan (from BSI) as their house yeast strain so pair that with the above and we the makings of some tasty IPA.
I got to the brewery early in the morning, boots on, and let John know that I was ready to get my hands dirty. 2nd Story brewing is in the Old City section of Philadelphia, and if you're familiar the area you'll know that space in these old buildings is at a premium. For the neighborhood however, the brewpub is actually quite big, but the brewhouse itself is a bit tight especially with me and a few friends tweeting and snapping photos all day. A lot of thought went into laying out the brewhouse to maximize what limited space there is, its an impressive system.
Pretending to stir the mash, note the strike water and grist are already fully integrated.
You can see the arm that the auger and HLT tubing meet and excrete the mash.
We started in the basement where we opened 1,000 pounds of grain sack by sack and fed it into the mill which is transferred up to the second floor brewery via the auger. John already had our water measured out and heated to our strike temperature in the HLT before I got there, we hooked up a few hoses and started to mash in. This is the point where I was supremely impressed by the ingenuity of this system, the strike water and milled grain are fully integrated as it is pumped/auger'd meeting in the same tubing that is then dropped right into mash tun, video proof. Despite the obligatory mash stirring photo, there is absolutely no stirring necessary. 

The brewhouse uses steam jackets to heat the kettle and HLT but the mash tun is just an insulated vessel with a loose fitting lid. However, the false bottom and simple pick up tube on the mash tun are very efficient at leaving virtually all grain particles behind leaving no reason to recirculate. After the mash was complete we used the grant to prime the pump, then pumped right into the boil kettle. With such a large volume of wort in a huge boil kettle its hard to see the rate at which the runnings are flowing.  With a smaller volume of liquid in the Grant you can more easily monitor the flow rate coming out of the mash so you can match the flow of the sparge with some consistency. 
Thats the grant, on left is the panel you connect stainless tubing to transfer liquid via all vessels so there is not a web of hoses all over the floor. Another bit of genius engineering due to space constraints.
As the first runnings filled the boil kettle we turned on the lower jacket to bring the wort to a boil and added the FWH addition of CTZ. After the whole kettle was filled we fired up the second (upper) jacket and we reached the boil in short order. Another bit of ingenuity that impressed me was all of the steam coming off of the boil (its a lot) is captured and condensed back into water then moved over to the HLT to be used for cleaning, so awesome.
I had to change my shirt, it got soiled.

After a 60 minute boil we turned the jackets off and sent the wort through the chiller and back into the kettle to bring the wort temp down to 185F for our whirlpool addition of Citra/Amarillo then rested for 45 minutes. When the whirlpool rest was complete the wort was pumped through the glycol chiller and chilled to 55F, aerated inline, then through the yeast brink and into the FV, all closed system as you can see on the right. But before the wort was aerated and pitched John filled a few of my fermenters with chilled/unpitched wort for me to use various yeast strains and methods at home. There will be multiple follow up posts on all of the different ways I split the 20 gallons he allowed me to take, from 100% Brett (some new blends) to a barrel aged version using my Tired Hands Emptiness culture, this wort will produce many a variation.  
Gimme that wort John, the aromas filling the brewpub at this point were amazing.
Grain gets shoveled onto the floor, then down an 8" pipe that leads to the basement and into trash bins.
You can barely see the green pipe between my legs.
There were a few takeaways from the day for me most importantly that the process itself is not much different than what we all do at home, only bigger and surprisingly easier due to pimped out equipment. Grain out and cleaning the mash tun was a ton of work, hot, sticky and messy but as a one time thing it was actually kind of fun. It was a truly great experience, and I am grateful to John and the Philly Homebrew Club for offering up the opportunity to win the prize. I look forward to winning again in 2015 and making John introduce some Brett to his brewhouse :). As of this posting Riverwards IPA is still on tap, despite my best efforts to drink the entire tank, so if your local go buy a pint and say hi to John. Tasting notes to follow.
You want me to get inside the mash tun to clean it?

Notes: 5 gallons at home was pitched with 500ml of fresh "Brett" Trois slurry, ironically 2 days before the new broke that it may not be a strain of Brettanomyces. 13 gallons was pitched with my Tired Hands Emptiness culture, and racked into my 1 year old Dad's Hat barrel blended with 2 gallons of 1 year old Farmer in the Rye. The final 2 gallons was split into 1 gallon fermenters split with 2 brett blends that Richard from Mark of the Yeast. There will be a post on all of these variations as they materialize, with the barrel aged version last of course.


  1. Looks like an awesome time. You really didn't go over how the beer tastes. How close to the original?

    1. Better than the first batch for sure, much more dry, which accentuated the bitterness more than I expected. John did 2 variations on this on cask, one dry hopped with Citra and one with Simcoe, I missed the Citra but the Simcoe was chewy, creamy and absolutely amazing. I wanted to fit tasting notes into this post but it was getting wordy, I will have notes up shortly.

  2. Sounds great! Did you happen to aerate the batch that you inoculated with WLP 644?

    1. At the time I thought WLP644 was Brett, which we know now it is not, so I treated it as such. For 100% Brett beers I aerate but not as much as my "clean" beers, I usually just shake for 15-20 seconds as opposed to using pure o2. Very scientific I know.

  3. If you are using Bru'n water what profile would you use? Or what was the water profile that you did use with Riverward IPA. Im having an internal debt with myself to whether I should use a balanced profile or high sulfate pale ale profile.

    1. Recently I have been trending more and more towards a higher Chloride to Sulfate ratio, keeping Mash pH to 5.3. I recently brewed a batch of HopWards with a 2:1 Chloride:Sulfate and it was super creamy and awesome.

    2. Ok, thanks. So it's more of full body malty profile.

    3. Hi Ed, would you recall the specific balances in that 2:1 Chloride:Sulfate ratio you used in HopWards? I've brewed your original recipe a couple times with the 1:1 ratio and really liked it, but I'd love to try to get more of that creamy, pillowy mouthfeel into it. I'm thinking the 2:1 ratio might be the right step towards that. Thanks!

    4. Recently been hitting Cl: 180ppm and S04 100ppm. Not exactly dead on 2:1 but very close.

  4. Keep doing awesome read few posts on this site and I imagine that your online journal is exceptionally fascinating and has sets of phenomenal data.

  5. Great content material and great layout. Your website deserves all of the positive feedback it’s been getting.

  6. Its a great pleasure reading your post.Its full of information I am looking for and I love to post a comment that "The content of your post is awesome" Great work.

  7. Great Post! Writing from Argentina, trying to emulate this Riverward IPA. Couple of questions.
    1. So the water ratio is 2 Cl 1 So4? I was going to try it the other way around.
    2. And this is the most important question, maybe you can clear my doubt out. The river ward recipe from other sites talks about a FWH addition of Zeus, but this recipe doesn't say anything about it, and talks about a 60 min hop addition.
