In the July/August 2009 issue of Zymurgy there is an article by the brewmaster of Blind Pig Brewery where he talks about brewing Double IPAs. He also provides a clone recipe for Pliney the Elder which I brewed Tuesday night. The grain, hops and yeast with tax cost $70.41. The 13 oz of hops accounted for $37.55 of the total. The recipe is for a 6 gal batch with a net of 5 after hop loss due to dry hopping. The boil is 8 gals and I have a 35 qt pot so it was very full but after the boil, chill and transfer to my primary fermenter, I ended up with 5.5 gals, not 6. Here is the recipe as it appears in the July/August 2009 issue of Zymurgy:
11 lb Two-row pale malt
0.5 lb Crystal 45 malt
0.5 lb Carapils (Dextrin) malt
0.4 lb Dextrose (corn sugar)
3.50 oz Columbus 13.90% AA 90 mins
0.75 oz Columbus 13.90% AA 45 mins
1.00 oz Simcoe 12.30% AA 30 mins
1.00 oz Centennial 8.00% AA 0 mins
2.50 oz Simcoe 12.30% AA 0 mins
1.00 oz Columbus 13.90% AA Dry hop (12 to 14 days total)
1.00 oz Centennial 9.10% AA Dry hop (12 to 14 days total)
1.00 oz Simcoe 12.30% AA Dry hop (12 to 14 days total)
0.25 oz Columbus 13.90% AA Dry hop (5 days to go in dry hop)
0.25 oz Centennial 9.10% AA Dry hop (5 days to go in dry hop)
0.25 oz Simcoe 12.30% AA Dry hop (5 days to go in dry hop)
Tomahawk/Zeus can be substituted for Columbus
White Labs WLP001 California Ale Yeast or Wyeast 1056 American Ale yeast.
Original Gravity 1.070
Final Gravity 1.011
IBUs: 90-95 (actual/not calculated)
ABV: 8-8.5%
SRM: 7
Directions: Mash grains at 151-152 degrees F (66-67 C) for an hour or until starch conversion is complete. Mash out at 170 degrees F (77 C) and sparge. Collect 8 gals (30 L) of run off, stir in dextrose, and bring to a boil. Add hops as indicated in recipe. After a 90 minute boil, chill wort to 67 degrees F (19 C) and transfer to fermenter. Pitch 2 packages of yeast or a yeast starter and aerate well. Ferment at 67 degrees F until fermentation activity subsides, then rack to secondary. Add first set of dry hops on top of the racked beer and age for 7-9 days then add the second set of hops. Age 5 more days then bottle or keg the beer.
Extract substitution: Substitute 6.5 lb of light DME for two-row malt. Due to the large hop bill for this recipe, a full wort boil is recommended. Steep grains in 1 gal of water at 165 degrees F (18 C) for 30 minutes, then remove and rinse grains with hot water. Stir in dextrose and top up kettle to 8 gallons and bring to a boil. Add hops as indicated in the recipe. After a 90 minute boil, chill wort to 67 degrees F (19 C) and transfer to fermenter. Pitch 2 packages of yeast or a yeast starter and aerate well. Ferment at 67 degrees F until fermentation activity subsides, then rack to secondary. Add first set of dry hops on top of the racked beer and age for 7-9 days then add the second set of hops. Age 5 more days then bottle or keg the beer.
My notes: I assume the 9.10% AA is a typo for the Centennial hops. The Centennial hops I bought were 8.00% AA and that is what is listed in the first addition of Centennial to the wort. I used the Wyeast American Ale yeast but at $7.25 I only used 1 package. My fermenter is bubbleing vigorously as I write this. I also did not reach 1.070 OG partly due to a mistake I made by adding malto-dextrin instead of dextrose at the beginning of the boil. Duh! I'll look at the label next time! My OG was 1.058. I later dissolved 1 lb of dextrose in sterilized water, cooled it to 70 degrees and added it to the fermenter. I know Charlie Papazian would tell me not to worry about it and relax and have a homebrew so that's what I did.
