4 days prior to brew I started two 1.5 L starters from 2 packs of WLP090 yeast. Let ferment and stored in fridge until brew day. On the morning of brew I decanted starters and pitched into new 1 L starter so it would be active before pitching.
Had to substitute Golden Promise for Marris Otter. Grain bill was split into two even grain bills. Milled 2 days before brew and stored at homebrew store at 72 degrees,

9/14/19: brewed with Matt and John at homebrew store.

Roughly 11:30 AM start time. Started with 7.5 gallons of RO water, treated with 4.9g of baking soda, and 7g of calcium chloride. Pre-heated mash tun with 178 degree mash water. Doughed in with 20 lbs of grain, achieved 155 degree mash temp, let rest 90 minutes and stirred every 15 minutes for first hour.

Repeated with second mash, achieved 160 degree mash temp, cooled with 2-3 qts of extra water to 156 degrees, then let rest for 90 minutes.

Vorlaufed both for 10-15 minutes each. Collected first runnings only into 15G kettle, boil volume 10G, pre-boil gravity between 1.082 - 1.084. Boiled for just over 3 hours on propane burner. Forgot to add yeast nutrient during boil. Cooled with copper immersion chiller to 90 deg.

Final volume was 5 - 5.15G into 6G glass carboy. Original gravity of 1.145-1.147 (reading was off the refractometer scale).

Placed fermentor into ferm chamber set to 66 deg. Temp stabilized ~1.5 hours later. Pitched 1 L new and very active starter, vigorously shook for 2-3 minutes to aerate.

@12 hours post pitch - very active ferm, 1-2" krausen
@24 hours post pitch - nearly high krausen 2-3"
@36 hours post pitch - high krausen, very active, almost into blow off tube

Partigyle Brew:
Decided on an english mild/brown ale

Target OG: 1.050
Actual OG: 1.045
Target IBU: 30
Target Volume: 5.5G
Boil: 60 minutes

Ran 3.5G untreated Louisville tap water through each mash tun. Let rest for 30 minutes while we handled the main brew. Vorlaufed briefly, then collected 6.5G second runnings into 10G boil kettle. "Boiled" on induction burner that maintained a weak simmer.

Added 1oz EKG/Fuggles at 50 for ~25 ibus
Added 1oz EKG/Fuggles at 5 minutes for ~5 ibus

Cooled with copper immersion chiller to 90 degrees. Then placed in ferm chamber set to 66 degrees alongside RIS. Temp stabilized ~1.5 hours later. Pitched 1 pack of S-04 then lightly shook for 30 seconds to aerate.

@12 hours minimal ferm
@24 hours thin krausen
@36 hours active ferm, 1" krausen

10/10: Bottled half of the brown plain with dextrose. Targeting 2.3 vol co2. Remaining 2.75G was racked into 3G better bottle with 2 split, scraped, and chopped wet Madgascar Vanilla beans (that had been soaking in ~1-2 oz of Heaven Hill vodka for 2-3 days).

10/23: Dry beaned 30g (~11g/G) of Sunergos Tanzanian Peaberry coffee (roast date: 10/10). Beans were placed into sanitized grain bag, filled with coffee/stainless steel nuts, and suspended in beer for ~24 hours.

10/24: Packaged vanilla/coffee portion, targeting 2.1 vol co2, primed with dextrose. Flavor and aroma was pretty incredible, vanilla added body/sweetness and the fresh roast smell of coffee was very pleasant.


Notes for Next time:
-don't forget to add yeast nutrient
-we collected more pre-boil volume and still had wort left in the mash tun, consider lowering initial mash volume by 0.25G each
-partyigyle beer was much weaker than it could have been. Sparge with less volume, and collect any remaining wort from tuns before sparging
