This was the first batch where I used yeast cultured on my new stir plate. The yeast was culturing for around 24 hours when I pitched it, looking to be at high krausen. Also, it was my first time working with pilsner malt.
Per my usual custom, I am naming this IPA after a supercontinent--Pannotia this time around.
Pannotia White IPA
- 7 lbs. Pilsner (Weyermann) malt
- 3 lbs. white wheat malt
- 1 lb. flaked wheat
- 8.10 g gypsum (added to boil)
- 1.73 oz. whole Cascade hops (first wort hopping and 90 minute boil; 2014 crop, estimated 4.29% alpha acid)
- 1 oz. whole Cascade hops (first wort hopping and 90 minute boil; 2013 crop, estimated 2.61% alpha acid)
- 0.35 oz. bitter orange peel (added for last minute of boil)
- 0.15 oz. coriander seed (lightly crushed, added for last minute of boil)
- 3 oz. Citra hops pellets (added at flame-out; 13.2% alpha, 3.7% beta)
- 1 oz. whole Cascade hops (added at flame-out; 2013 crop, estimated 2.61% alpha acid)
- Belgian Wit ale yeast (WLP400), prepared 24 hours in advance with 1.5 L starter
- 3 oz. Citra hops pellets (14 days dry-hop, 13.2% alpha, 3.7% beta)
- 1.059 o.g., 1.010 f.g., 6.5% abv
- 50.2 IBU
- 3.7 SRM
- I mashed in with 3.5 gallons of water at 159°. The mash stabilized at ~147° within 5 minutes, which was a little on the cool side for my taste. So, I added 1 gallon of ~185° water, stirred it a bit, and got the mash to 151° within a minute. The mash still measured 151° after 10 minutes and 149° after 40 minutes.
- I drained the mash tun, collecting ~3 gallons of wort with a gravity of 1.064. The hops were in the kettle starting at this point. Note that I adjusted the alpha acid for the calculations based on the age of the hops, using the hops aging tool in BeerSmith.
- For mash-out, I added 3.5 gallons of water at ~185°.
- All told, I collected 7 gallons of wort with a gravity of 1.045. This works out to ~74% efficiency.
- I added the gypsum and brought the wort to a boil. Because I used pilsner malt, which is supposed to have a higher susceptibility to DMS production, I boiled for a total of 90 minutes.
- One minute before flame-out, I added the coriander and bitter orange peel. At flame-out, I added the Citra hops pellets (contained in a mesh bag) as well as the whole Cascade hops.
- I cooled the wort down to ~70°, transfered to the carboy (aerating with the Venturi pump along the way), and pitched the yeast (starter and all).
- This beer was brewed on Monday, April 6, 2015. Starting gravity was 1.057, just a touch below my predicted gravity (1.059). This is likely due to a slightly lower boil-off rate. Total volume was 5.25 gallons. I placed the carboy in my fermenting chamber, and set the temperature controller for 70°.
- In less than 12 hours, the fermentation was proceeding quite vigorously. Score one for using a starter!
