Batch 101, St. Brigid's Lake IPA

Another batch of St. Brigid's IPA. I bought a pound of Centennial this year, so I had the right combination: Centennial, Cascade, and Chinook, the best of the "C" hops!

I got a brand new Blichmann Brewmometer for Christmas (thanks Linda!). I got it installed on my mash tun this morning, so thought I'd brew this evening. My old thermometer is still stuck at 160F. The Brewmometer barely fit, it is quite a bit larger in diameter than my old one. I also had to make the hole in the kettle a little larger.


10 gallon batch.

Batch Notes
Actually measured 7 grams instead of 1/4 ounce, it works easier with my scale.

Half of the 20 minute hops are actually FWH, the other half are actually at 20 minutes.

Mash at 156F for 60 minutes, collected 14 gallons.  Temp didn't fluctuate more that 1 degree during the entire mash.  It's nice to have confidence in a thermometer.

OG: 1.062 actual
The OG is higher than I'd calculated, which puts this batch more in the middle of the range for the style.

Balance value: 3.357


Jan 7, 2011: Gravity is down to 1.018, so almost done, or close enough not to matter.  I'm going to let it sit on the yeast cake for another week while dry hopping anyway.  Added dry hops, 1 ounce each of Chinook, Centennial, and Cascade.  The hydrometer sample tasted great!  Recalculating numbers, the higher OG bumps the expected ABV to 1.057, assuming the gravity doesn't drop any more.

10/813
