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.

AG#92 - Klaatu Verata Nictu

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…

AG#85 - HopZilla IPA

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.

SB_Specials_Kala_Black_IPA

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.

Pioneer’s Gold – A Barley wine for the National Homebrew Competition (or maybe the Year after) and using fresh live yeast from work. I’ve been meaning to try this for a while and after seeing Graeme Coates’ brewday I thought I’d go for it. I’ve gone for 15 litres as i don’t think its something I’ll drink very fast and its nicely left room in the copper for an extra 10L sparge to extract more from the mash. Hopping is some Pioneer pellets and older First Gold that were in the Hop-Freezer.

Fermentables:
Pale Malt – 90%
Wheat Malt – 5%
Caramalt – 4%
Amber Malt – 1%

Hops:
First Gold Whole 7.9 % @ 60 mins – 25g (after a long boil down first)
Pioneer Pellet 9.5 % @ 60 mins – 17g
First Gold Whole 7.9 % @ 10 mins – 17g
Pioneer Pellet 9.5 % @ 10 mins – 17g
First Gold Whole 7.9 % @ 0 mins – 39g
Pioneer Pellet 9.5 % @ 0 mins – 56g (What was left in the bag)
Golding Whole 5.1 % @ 0 mins – 3g (I ran out of First Gold so made a small extra addition)

Final Volume: 15 Litres
Original Gravity: 1.100
Final Gravity: 1.024
Alcohol Content: 10.1% ABV
Total Liquor: 26.7 Litres
Mash Liquor: 17.2 Litres
Mash Efficiency: 70 %
Bitterness: 73 EBU (The First Gold are pretty old now so i don’t expect to make this figure)
Colour: 22 EBC
Yeast: Thick skimmed yeast from Saltaire Brewery, fresh as you like.
Mash: 3 hours at 65°c, aimed for 66°c.

I went back to my old HTC Android for Strike Temp & Batch sparge volumes, this is even though I just got Beer Alchemy on the iPhone:
Image
Pretty full, but I’m sure I could get a fair bit more in sometime:
Image
First runnings, I recycled about 12 litres:
Image
From the first sparge I collected 20 Litres @ 17.4 Brix so did an extra 10 Litre sparge and got 32 Litres @ 13.8 Brix, just over 64% Mash efficiency on the First sparge which I am quite happy with:
Image
The first sparge was added kind of on the fly, then the extra 10 L sparge was added via my beta-version spinning sparge arm and the solar pump:
Image
On the boil, I had to simmer for a while until I could turn up the heat:
Image
Boiled off about 12-13 litres before adding the first hops, 3 hours 20 mins total boil time!:

Pioneer Pellets & First Gold hops:

I didn’t realise at this point but I think my refreactometer may have been exaggerating a bit:

Steep hops in for 30mins at Flameout:

I ended up collecting about 18 litres after doing some liquoring back towards the end of the boil (Thanks Refractometer, I should have stuck with my instincts as I would have been right!) did some small sugar additions to rescue a few OG points ended up with 1091. I pitched 100g of fresh, thick live yeast from work, MrMalty said 80-100ml, yeast pitched at 17°c:

A fairly relaxed day, second breakfast, drop the Mrs off at the train station, and walked the dogs while the mash was on, left the copper cleaning until the day after. Fermenter in the fridge set at 18°c for the first 24 hours then will hold at 20°c for a day or two before letting it free rise to 24°c, if its anything like at work this yeast will need a bit of TLC with a rouse every now and then.

This was my first Brewday taking all the photos on the iPhone, cracking photo quality and much easier than using the Canon DSLR, I use Instagram without any filters which kept everything in the nice square-blog-able format 🙂

*1st May ’12 – gravity at 1041 @ about 20°c, tasting very fruity almost like US hops!

*3rd May ’12 – Gravity 1027 @ 22°c tonight, not far from 1024 predicted FG, given it a good rouse… still tasting pretty sweet, hope some of this will dry out a bit.

*8th May ’12 – Down to 1015 @ 22°c I’m hoping its going to stop soon, it was 1016 yesterday so its getting close.

*9th May ’12 – Steady at 1015 now, chilling in stages probably 17°c then down to 11°c before bottling.

*12th May ’12 – Bottled with 90g White Sugar, got 45ish 330ml-ish bottles, the waiting game begins…..

*10th Sep ’12 – Tasting rather good, a nice malty toffee mouthful with warm lingering alcohol, a sweet lemoniness is also apparent.
