Altitudinous Cable – I’m hoping for a ‘MagicRockBrewing Highwire / PartizanBrewing Columbus Chinook Cascade IPA‘ type of thing, bags of flavour and seriously dry hopped.
My 100th All-Grain Brewday was supposed to be an all-Fuggle Double IPA with a great big Fuggle Dry Hop, have beery mates round and cook food / drink beer / forget the Protafloc etc We’ll have to plan that for another time as I wanted something that will be distinctly hoppy with in-yer-face dry hopping, so what better beer to try imitate than MagicRock’s Highwire, a beauty of a beer at only 5.5%.

Fermentables:
Lager Malt – 82.5%
Caramalt – 8%
Vienna Malt – 5%
Munich Type I (Weyermann) – 4.5%

Hops:
Magnum – 12.7 % @ 60 mins – 27g (FWH)
Magnum – 12.7 % @ 30 mins – 27g
Chinook – 12.5 % @ 0 mins – 43g (30min Steep)
Cascade – 7.9 % @ 0 mins – 43g (30min Steep)
Columbus – 16.5 % @ 0 mins – 43g (30min Steep)

Dry Hops:
Chinook Pellets
Cascade Pellets
Columbus Pellets
(see later *edits for Dry hop additions)

Final Volume: 25 Litres
Original Gravity: 1.055
Final Gravity: 1.013
Alcohol Content: 5.5% ABV
Mash Efficiency: 75 %
Bitterness: 55 EBU
Colour: 10 EBC
Mash: 69c for 60mins
Yeast: Safale us-05

Easy brewday, did a bit of a Garage tidy while I was at it.
I only gave the mash 1 Tsp of Calcium Chloride as I’ve had some comment on the dryness of my homebrew, so no other liquor salts for this brew just as an experiment.

*22nd May ’13 – Gravity at 1014, first dry hopping addition of 3g/litre Cascade, Columbus, Chinook (75g in total) it will be left at 20°c for 2-3 days, I’ll give the FV a stir tomorrow.

*24th May ’13 – Steady gravity, Tasting good but still subtle so…. chilling to 17°c and dry hopped with just less than 5g/litre, 24g Cascade, 50g Columbus, 50g Chinook. Again I will stir the FV tomorrow. I may do a third dry hop 😉

*27th May ’13 – The 3rd Dry Hop: 24g Columbus, 22g Chinook, 21g Amarillo (2.65g/litre in total), so all in all its been dry hopped with 10.65g per Litre of beer. Tastes a bit raw.

*1st Jun ’13 – Bottled with 120g White Sugar, I lost 3 Litres to the hop pellets/yeast, tasting pretty good has some rough edges but nothing that a week or two in bottle won’t cure. At this stage I would think that an almost 100% Chinook dry hop would be closer to a MagicRock/Partizan beer.

The remaining sludge in the FV, the thought goes through my mind… I wonder what would happen if I brewed another beer and dumped the wort straight onto a mess of pellets & yeast like this?:

*8th Jun ’13 – early taster, its carbonated up just right, the bitterness pretty good, the dry hopping is going to take a week or two more to round off and loose the rough edges, cloudy as heck thanks to all those hops!

*14th Jun ’13 – Another taster, hops settling down a bit, strong bitterness until the pallet re-sets, I think I was right saying a bit more time 🙂

*13th Aug ’13 – Some time later, this is smoothing out but keeping its intense hoppyness and a nice sort of flat-tingle-spice-bitterness, it finishes with the body coming back in as the hops linger in the mouth. Next time I’ll not leave the hops in as long and maybe concentrate on dry hopping with just Cascade & Chinook.

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.

Cheers
