Brewing Notes
12/16/15 - Yeast Starter:
2 Liter yeast starter: 7c of water, 7oz Extra light DME, 1/2 tsp yeast nutrient, boiled 10 minutes and chilled to room temperature. Fermented on a stir plate.
12/18/15 - Brew Day:
- Sanitized (star san) my cold side equipment in the big mouth bubbler primary.
- Heated 18.5 quarts of water with PH 5.2 to 168 F in 8 gallon stainless HLT on outdoor propane burner
- Mashed in in 10 gal Igloo cooler, paddled until everything was well mixed and there were no dough balls. 60 minute mash rest
- 0 minutes: temperature was 151-152F
- 15 minutes: paddled, temperature was 149-150F
- 30 minutes: paddled, temperature was 148-150F
- 60 minutes, temperature was 148F, began vorlauf
- Manual Vorlauf: I run a 2 cup measuring cup full of wort out of the valve and gently pour this on top of the mash. Then I repeat until I'm satisfied with the clarity. This takes about 10-15 minutes.
- Ran off and fly sparged with 15.38 quarts of 190F with pH 5.2 water
- Ran until the mash tun was dry, about 30 minutes
- Boil gravity was 12.8 - 1.051, which missed by 8 points.
- Brought to boil - 60 minute boil time
- Added:
0.5 oz Warrior (pellets) @ 60 min.
1.0 oz Centennial (pellets) @ 30 min.
0.5 oz Amarillo (pellets) @ 20 min.
0.5 oz Simcoe (pelelts) @ 20 min.
1 Whirlfloc Tab @ 15 min.
1.0 oz Amarillo (pellets) @ 10 min.
0.5 oz Simcoe (pelelts) @ 5 min.
0.5 oz Centennial (pellets) @ 0 min. - Chilled and siphoned to BMB, Volume was 5.25. Look at the Whirlfloc work.
- Took an OG brix reading of 15.2% which calculated to to 1.061. Obviously I missed on efficiency pretty bad here. Based on the pre-boil reading I didn't get a bad reading on the refractometer. There's a possibility I had a bad crush on the grains. Someone was adjusting the mill at the LHBS just before I milled mine. The other possibility is that I didn't mash long enough at the lower temperature, but the temperature wasn't that low so I doubt this is it. I made some changes to my sparge for #35, which I'll spell out then.
- Pitched entire yeast starter, volume was now about 5.75 gal
Transfer to 5 gal glass carboy. Measured 7.4% brix which calculated to 1.010.
1/3 - 1/23 - Secondary Fermentation:
The reason this one had longer than a 2 week secondary was just because of collecting the grapefruit zest. Between my house and my parents' house we collected the zest of 10 grapefruits with as little pith as possible. To keep these hydrated and preserved as well as sanitize we soaked them in vodka (just enough to cover the zest) for at least 48 hours.
On 1/16 dry hopped with 1.5 oz Amarillo, 0.5 oz Centennial, and all of the grapefruit zest and vodka. I had to pull a little bit of beer out of the carboy to make room for all of this addition.
1/23- Kegging:
I bought myself a 3-tap kegerator for Christmas with a little help from my family. I had not yet taken delivery on it, but the LHBS hooked me up with the first keg, gas bottle, regulator, gas line, and disconnect. Here's what I did:
- Cleaned and sanitized keg
- Reassembled keg except for stud and poppet on the "out" side so that the dip tube would fill
- Siphoned beer through sanitized mesh bag to strain
- Closed the keg
- Pressurized the keg to 20 psi then shut off gas
- Vent, Fill, Vent, Fill, Vent, Fill
- Reduced pressure to about 16 psi
- Brought the keg down to the basement which was about 50F ambient. Left the gas bottle hooked up to force carbonate.
2/12 - 3-18 On Tap:
It probably didn't need the extra time in the keg but this is when I finally got the kegerator.
Like I said - favorite beer to date. Expect to see it again soon. I wouldn't change a thing. I don't really care if its not a "clone" so I never did a side-by-side.
