Title: Double IPA 9%
Post by: admin on September 12, 2012, 12:16:56 PM
This recipe is loosely based on Brewdog's Hardcore IPA (http://www.brewdog.com/product/hardcore-ipa), and really is rewarding if done right. The end result is very close to the original. It has to be brewed carefully as the grain bill is so large -- make sure it's not too big for your mashtun!

A few things that you need to know.
[list bull-blackball]Type: All Grain
Batch Size: 15.00 L
Boil Size: 18.06 L
Boil Time: 90 min
Brewhouse Efficiency: 75.00

1.00 kg Dememera Sugar (3.9 EBC) Sugar 14.71 %
30.00 gm Cascade [5.50 %] DRY HOP
US-05 yeast 


Est Original Gravity: 1.113 SG (more likely around 1.090)
Est Final Gravity: 1.028 SG (anywhere down to 1.015)
Estimated Alcohol by Vol: 9.5 to 11% abv
Bitterness: 110.4 IBU
Calories: 841 cal/l
Est Color: 15.0 EBC

Prior to bottling or kegging add 85g of dextrose or table sugar to 150ml of water and boil for a few minutes. Add to your bottling bucket. This will give you 2.4 vols of CO2.

Age this one for 8 weeks.

  • Yeast. This one needs lots. A simple way is to pitch the wort on top of the yeast cake left over from a previous brew, preferably something light that won't affect the taste. If pitching dried yeast  you should probably use two sachets.
In case of dry yeast for a 15l batch and SG around 1.090 you'll need 13.8g of yeast. 1 sachet of fe US-05 is 11.5g.
Calculated with http://www.mrmalty.com/calc/calc.html

Btw. Which yeast would you recommend for that receipe?

Putting this on my list of to-do. If you have some ready for the December meetup I'd love a taste.

QuoteGood spot on the quantity, but I would still recommend over pitching. The first time I did this recipe with just one packet of US-05 it was a disaster. I haven't tried it with two, so I'm guessing that would be better. But I've always used the slurry from a previous brew since then.

Tip of the day - use 1/3 of the slurry for perfect results - in my humble opinion !
