Well, I finally got my butt out of bed to embark on what was my most ambiguous day in the Brewery to date. I made two beers, Parti-gyle style. Parti-gyle brewing was a standard brewing procedure many years ago, and still is utilized at breweries today such as Fuller's in the UK. The concept is to take the first runnings of a mash to obtain the highest gravity wort. This wort will be used to brew a big beer, generally over 8% ABV. Additional runnings are fed to other kettles. The gravity of the wort in these kettles will be significantly less and be used to make common session beers style beers
I used the first runnings for my Russian Imperial Stout which I am predicting to be around 10% abv. I was going to cap off the mash (add grain) so the second runnings would make a beer about 1.050, but I had an issue and we will get to that later.
Brewday started around 8am. This was the first time I have ever tried to utilize my 52 qt Coleman Xtreme mash tun to capacity. I usually only make 5 gallon batches, but to obtain enough wort from the first runnings the mash tun needed to be filled more as if it was a 10 gallon batch. I weighed out my 24 lbs of malt using my sweet new Ultraship scale! And then started to hand mill... thats right hand mill :( I unfortunately had lent my drill to a family member early this week and completely forgot about. That was a pain in the...arm! (Note to self, need to start hitting the gym)
I almost had a disastrous moment as I emptied my entire strike volume into my mash tun. I was almost about to start doughing in the the grain when my brew angel started screaming "Shegogue... NOOOOO!" Quickly I realized why I could not proceed. I had forgotten to place my manifold in the mash tun! This could have been a horrific problem had it not been caught. I was able to runoff all the water back into my kettle, install the manifold and only lose about 15 minutes.
I collected my first runnings of 7 gallons of about 1.077 gravity and started my boil. I added 3 ounces of 15.8% AA Warrior hops to the kettle at 60 minutes and when about milling my additional 3lbs of grain for the second beer. I was using a great calculator from Brukaiser's website to approximate the gravity of my remaining runnings.
Unfortunately, as I was chilling down the wort from the Imperial Stout, my mash tun decided to fall over! Presenting hot stick wort ALL over the garage floor and my feet, ouch! I think I see a designated brewstand build in my future as that trash can clearly isn't cutting it. After salvaging what I could, and then cleaning up the mess, I was able to draw off about 3.5 gallons of 1.031 wort for a 2.5 gallon batch.
Anyways, it was about an 9 hour messy brew day. but I will get two different beers out of it, so well worth it. The two beers are happily fermenting in around 66 degrees with Safale S-05.
It's nice to have a Brew Angel
ReplyDeleteYes, it is!
DeleteThis is a detailed breakdown of the Parti-gyle method, and hand-milling 24 lbs of grain is no small feat. It really shows how much preparation goes into managing complex processes, much like how nursing students feel overwhelmed balancing heavy workloads when they search to pay someone to take my teas exam during busy assessment periods. Having the right strategy makes all the difference whether you are brewing a heavy Russian Imperial Stout or handling academic milestones, and I am looking forward to seeing how the second runnings turned out in your next update.
