Double IPA 9%

[admin]

This recipe is loosely based on Brewdog's 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]

• This is a 15L batch!
  
• If you are using whole leaf hops that you will most likely loose a lot of wort due to soakage... and there are a lot of hops in this one! Budget an extra litre of two if you are.
  
• As there is a lot of grain in this it's necessary to make sure the wort is thoroughly aerated. It might even help to aerate it a second time, like 24 hours after fermenation starts.
  
• 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.
  
• Ferment at 18°C for 5 days, rising to 22°C for the last day.

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.

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.

Good 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 !

Cheers! Will give it a go and hopefully have some to take to a meet up in 2013
