The Double IPA, Hmmm

I’m a little confused over the matter of brewing Big IPA’s, in regard to getting bitterness and some dryness into these high strength Imperial or Double IPA.
Consider my AG#92 Klaatu Verata Nictu its an all malt DIPA but the residual sweetness after fermentation is far too high, time in bottle is s-l-o-w-l-y drying it out and its a nice beer, but much more of an American Barleywine than displaying the bitterness characteristics I was aiming for… It would seem that my predicted 200 IBU could have been doubled to 400 IBU to help cut through the sweetness.
This is theoretically where a Sugar addition comes into play to help dry the beer out…
Now consider this AG#85 HopZilla IPA which did have a sugar addition for the purpose of drying the beer out, yet I still got an annoyingly high level of residual sweetness after fermentation, this did eventually dry up and display its proper character in bottle but it took blooming ages! I think I have 1 bottle of this left which I assume will be the dogs bollocks by the time I crack into it.
There is nothing wrong with either of the above beers apart from me not getting what I was aiming for, for my next experiment I will be trying a 10% addition of Dextrose, and a long cool Mash with less malts that could be adding Dextrins to the wort.
The following questions arise:
- Mash Temp?
- Liquor to Malt Ratio?
- Mash Duration?
- Amount & Type of Copper Sugars?
- Malt selection?
- Liquor Treatment additions?
I feel a MASSIVE dry hop is needed on these higher gravity beers, done in two stages.. i.e. Once in the FV, then transfer to Conditioning/Secondary for a while before doing a Second or even Third Heavy dry hop.
We brewed Kala BIPA, 6.2% @SaltaireBrewery a short time ago, I know the ABV is considerably different but we used a sugar addition of almost 10% to great effect in this beer making an amazingly easy drinking beer that went down like a 4% session ale.
Its all fun 🙂 I’d be really interested in how other homebrewers / brewers get their level of bitterness & Dryness in their DIPAs.

Quite a Full bucket of malt:
FWH, 250g of Amarillo:
Hops in the copper, there is some wort underneath!:
100g at 15mins left to boil:
Hop Stew, the spoon just stands up in it there are so many hops in the copper:
There is a IC in there somewhere:
About 5 points low on my target, I was half expecting this with such a large amount of Munich Malt coupled with the massive amount of Hops in addition to the compensated 5 Litres of losses guestimate!:
The Twins:
😉 US-05 dry sprinkled at 23c
I’m guessing the US-05 will finish lower than predicted so the ABV will hopefully be around that predicted.
*Bottled 4th Sept ’10 with 65g White Sugar
*Last of the bottles 3rd March ’12, yes… 2012! This has really changed, this was a Brewdog-esque in-yer-face Bitter-bastard of a beer, now it is delicate and refined with honey sweet notes on the nose, an altogether different beer. I would put it in the same class as an aged Fullers ‘Brewers Reserve’, its making me want to brew it again and just leave 40 bottles well alone for 2 years before tasting. Mmmmm 🙂
Probably Due To Network Congestion
