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 πŸ™‚ I’d be really interested in how other homebrewers / brewers get their level of bitterness & Dryness in their DIPAs.

Cheers

The day so far:
The mash was on last night at 00:50 and the temp was 66Β°c, at 9am this morning it had dropped to 59Β°c.
I did 1 sparge at 80Β°c with an hour’s Mash-out and collected my pre-boil volume in the copper, as I had expected this was lower than the predicted pre-boil gravity (10 points too low).
I did a second sparge at 80Β°c with a 30min Mash-out of 12 Litres while boiling the first run-off hard, ran off about half the mash then boiled down some more before running off the rest of the mash. I also added the sugars at this point, and continued boiling down until I reached 1086/7 when the bittering hops went in which will hopefully put me in the 1096 area for the end of the boil.

7 Degree drop over about 8 hours:

173g Safale US-05 yeast skimmed from previous brew and kept in the fridge for a week at 4Β°c, I’ll pitch the lot at 18Β°c:

OG: 1095 Temp corrected (Brix 23.8 with Refractometer = 1096):

Running to FV:
Pretty much hit my predicted OG, yeast pitched (still smelling of Nelson Sauvin hops from AG#70, if it wasn’t that I’ve just ruined an entire brew!) **Update, the beer in my Glass is Ta Moko, it smells just like the yeast, beer is fine)**
Copper is being very slow to run off, must be the thick sticky wort.
Its almost time for a beer, a Chilled very-early taster of Ta Moko just to see how its doing πŸ™‚
I think I’ll be buying some more Basra Date Syrup as it tastes very good and would lend its self very well to a Belgian Ale.

*3rd Jan ’12 – Gravity is currently 1064-ish, Tastes good, some of the hopping coming through and some Fruity stuff which might be the Date Syrup.
*4th Jan ’12 – 1050
*Bottled 18th Jan ’12 – with 60g of White Sugar, filled 50-off 330ml bottles.

*29th Feb ’12 – Taster:
The Carbonation is just about right, a good hiss when popping the cap and a solid mouth tingle.
Beer Colour is dark as it gets, if i shine a very bright LED torch at one side of the glass I can only just see a very, very faint red shape thru the glass.
Smells a leathery, dry, with a touch of alcohol and coffee.
Tastes, full mouth oily coating body, a fair amount of alcohol which lasts as long as the mouth coating, some coffee & liquorice.
I am, again, glad that i used sugars in this beer πŸ™‚

*2nd May ’12 – Just having a bottle of this, its rather good… maybe more like a Black IPA as the sugars have obviously helped to dry it out, very drinkable πŸ™‚

*6th Jun ’12 – Taster time! This is rather bloody good, a full smooth and oily mouth feel, crisp tingly carbonation, its getting to the stage of being like Warm Boot leather and just as chewy πŸ™‚

Something a little different today and almost all made up with a little reference to a recipe I found online, could taste pants, but hopefully it will be a hot ‘n spicy 4.4%-ish Ginger Ale.

The Ingredients & recipe go something like this:

  • Approx 21-23 Litres of hot liquor from the HLT
  • 1.4Kg Ginger root, finely sliced
  • 6 Lemons, finely sliced
  • 1 Lime, finely sliced
  • 1.5Kg Caramalt, steeped in Mash Tun then all hot liquor Sparged through it
  • 1.25Kg White Sugar
  • 250g Soft Dark Brown Sugar
  • 150g Demerara Sugar
  • 40g Ground Ginger followed by 4 Heaped Tsp of the same
  • 1/2 Tsp very hot Indian Chilli powder
  • 3/4-1 Tsp Cream of Tartar
  • Yeast Safale s-04

Put all the ingredients in a very large pan, bring to the boil and simmer for 20-30mins, followed by chilling down with the Immersion Cooler and running off to the FV.
I tweaked the OG to 1038 (the ingredient sugars reflect this) and also the extra Teaspoons of Ground Ginger & Chilli Powder were added near the end to adjust the spice / heat level. If the yeast ferments down to dryness it will be a 5.4% Ginger Ale πŸ™‚

Quite an easy couple of hours this morning, time will tell what it turns out like πŸ™‚

*Bottled 22nd Oct ’11 with 80g Demarara Sugar, fermented right down to 1000! so its dry, tastes a bit pants so I hope some carbonation lifts it, Needs sweetness!!!!

*Bottling update*

*Bottled 1st Aug ’10 with 60g of Light brown Sugar, tasting pretty good as a subtle Belgian.

*Tasted 5/9/10
Aroma:Β  Subtle Pear drops & Banana
Taste:Β  Spicy with more Pear Drops & some Sourness (possibly getting some of the Bobek & a bit of the Muscovardo in the finish)

Rather too easy drinking for a 7.5% πŸ˜‰

I used the guide from here http://oz.craftbrewer.org/Library/Metho … andy.shtml I’ll have a go with some more white sugar and try and get a really deep red.
500g of White sugar simmered at 127-135c with enough water to make a thick syrup and a good healthy pinch of citric acid for about 20 mins to gain some colour.
Image
This is half n half white sugar & muscovardo… we’ve just been eating it like toffee πŸ˜‰
Image
I used a silicone baking sheet draped over a couple of pie tins, much better than grease-proof paper
Image
I shall have another go with just White sugar another day and see how dark I can make it, maybe add it to a Stout or a dark Belgian Ale πŸ™‚

OK, I’ve gone and done it… these should be pretty different.. One weak and light, and One Dark and bitter!
Its a Geordie Yorkshire Bitter Kit split in two so I can mess around a bit with the brewing process, each of my two Fermentation Vessels

In FV1:

  • 20 Pints of Geordie Yorkshire Bitter
  • ASDA Smart price Liquor
  • 500g Medium Spray malt
  • 280g Brewing Sugar (just what I had left in a bag)
  • 100g Demerara Sugar
  • 20g Target Hops Steeped for 15mins in cafetiere (Hop Tea)
  • Kit Yeast used and brought to life for a good couple of hours before pitching
  • OG: 1040

In FV2:

  • 20 Pints of Geordie Yorkshire Bitter
  • ASDA Smart price Liquor
  • 500g Light Spray malt
  • 20g Saaz Hops steeped for 15mins in cafetiere
  • Safale s04 Yeast also working well before pitching
  • OG: 1032

Are they going to be OK or awful?
They might both be awful, but I’m thinking of these as experiments before I make a mess of any other kits πŸ™‚

**Update**
The Only Drawback here is I shall probably have to prime my bottles rather than priming my Bottling Bucket (which is FV2).
I do have some other buckets but I’d have to buy a drum tap, I’ll probably stick to 1 Bucket brews after this as I think I bent my head a bit trying to remember what volumes of liquor to add…
I mixed the Kit and the liquor in 1 bucket first to less than the stated full 40 Pints, then had 1L dissolved malt/sugar and 1L-ish of Hop Tea.
They both have a nice rocky head this morning πŸ™‚
My rehydrated yeast was pretty impressive as both the Kit Yeast and the Safale04 were trying to escape from their sterile cling-filmed jugs, the S04 was really going for it. Pitched the Yeast at about 24 Deg C.
As the pictures now show, yeast heads and constant 20 Deg C πŸ™‚

**Second Update**
Looks like FV1 is going to have Alcohol Content (ABV): 2.89% and FV2’s Alcohol Content (ABV): 3.94% as they have both settled at around FG: 1010

**Third Update**
Primed with 40g Brewing Sugar and bottled today (07/03/09) 23 Bottles of each and half a 2L coke bottle, all capped and at 20 Deg C for 1 week. I’ve wrote on all the crown caps so I don’t get them mixed up, GYB Saaz & GYB T – Geordie Yorkshire Bitter Saaz + Light Spray Malt & Geordie Yorkshire Bitter Target + Medium Spray Malt + Brewing Sugar + Demerara.
My sneaky little taste of both brews are quite promissing as they both taste better than the Woodfordes Wherry, I’ll be looking forward to these ones. πŸ™‚ The Saaz batch with the Safale s04 Yeast dropped out almost clear whereas the Kit yeast stayed in suspension a bit more.
Geordie Yorkshire bitter - Saaz & Target hopped batches

The two big plastic buckets I got from work streamlined my bottle sanitizing procedure, it still took me over an hour to clean, sanitize and rinse about 50 bottles though (did some extras so i wouldn’t get caught out). I also got a couple of drum taps from the HBS so I fitted 1 bucket with a tap and used it as my bottling bucket.
