AG#127 – Belgian Extra Blonde
Posted on: September 14, 2014
Belgian Extra Blonde – A mix of Pale (didn’t have any Lager malt), Carapils, Dextrose (partly sugar as I didn’t have enough of either), Oat malt & Wheat malt.
Hops are a tiny amount of Magnum to bitter then a subtle amount of Mittlefruh in the last 5 minutes and about half the coriander you’d expect to add to a Wit.
I’m fermenting with WLP757 which I revived from a 2 year old Whitelabs tube.
The Malts, mashed at 69°c for about 90mins:
The 9g of bittering hops!
The Coriander:
Second sparge running to copper:
Hit 3 points over my target so liquored back to 1047:
I’m hoping for just a hint of coriander and a light coloured, light bodied beer with enough but not overpowering Belgianiness! I’ve used sugars for part of the bill to keep the strength at 5% ish without adding too much colour.
*16th Sep ’14 – Yeast spewing all over the garage floor this morning, the ambient temp is about 19c and the FV is a fairly steady 22c, the WLP575 is smelling quite sulphurous, this could just be the yeast or I could be encouraging the sulphur because of my Sulphate additions (Calcium Sulphate & Magnesium Sulphate) all of which should dissipate as fermentation completes.
*Kegged 20th Sep ’14 – its about time i used my cornies!
*30 Sep ’14 – taster from keg, quite a soft carbonation, has Duvel-like properties some of the Sulphur is going but some of it could be the Coriander thats confusing me. I let the keg for 24 hours at 20psi and 24 hours at 30psi then left it until now, Ive put 30psi on it again and will test it again tomorrow.

Misc Bill
—————-
Single step Infusion at 66°C for 60 Minutes.
Fermented at 20°C with Safale US-05
I’ve basically made Hop-Stew 😉 And hit the OG I got 1082 and liquored back to 1080.
A few of the hops in the recipe changed as I went along due to what I found in the hop-freezer, I’ll dry hop in two parts half will go in when FG is reached then half 2 days later when I start chilling the beer so a half warm and half cold dry hop.
*19th Jul ’14 – I dry hopped this with 50g of Chinook & Nelson Sauvin, gravity was at 1011.5 @ 22°c
*22nd Jul ’14 – FG seems to be 1010 and steady, chilled to 17°c and dry hopped with the same T90 hops again.
*24th Jul ’14 – Chilled to 13°c, will chill to 8c before bottling.
*Bottled 2nd Aug ’14
*9th Aug ’14 – Tastes bloody good, the right level of bitterness with a medium carbonation and a good effect from the dry hopping, as you’d expect quite boozy with its 9% abv 🙂
AG#107 – iFuggle

iFuggle – I’ve been threatening doing this for a while, a big-ass Fuggle IPA, its an experiment and I may not like it but thats no reason not to try! And its a while since I made a British IPA.
The Dextrose will go in with the Protafloc in the last 10 minutes so as not to effect the hop utilisation, I’m using a couple of @MagicRockStu’s tips too.
Fermentables:
Pale Malt – 80%
Dextrose – 12.4%
Vienna Malt – 5.5%
Amber Malt – 2%
Hops:
Cluster Pellet – 7.9 % @ 75 mins – 150g (Start of boil)
Fuggle Whole – 5.1 % @ 5 mins – 150g
Fuggle Pellet – 4.3 % @ 0 mins – 100g (Dry Hop in FV)
Final Volume: 23 Litres
Original Gravity: 1.083
Final Gravity: 1.019
Alcohol Content: 8.4% ABV
Mash Efficiency: 75 %
Bitterness: 137 EBU
Colour: 15 EBC
Mash: 60-90mins @ 63°c (I actually hit 64°c)
Boil: 75mins
Yeast: Safale us-05 – 2 packs
The malts, a fairly full bucket with just over 7kg:
150g Cluster T90 pellets:
Second batch sparge running in:
In go the pellets at the start of boil:
The late whole fuggles go in at 5mins left:
I liquored back from 1085.5 to 1083, and ended up with 22.3L in the FV:
Yeast pitched at 20°c, in the fermenting fridge set to 20°c too, cleaned up, no fuss as usual 🙂
*16th Nov ’13 – Gravity at 1021, tasting rather sweet, could that 1°c higher than my planned 63°c mash temp be to blame? I was hoping for nearer to 1010 by now. I have dry hopped with with 100g Fuggles pellets and given it a good rouse, hopefully it will drop a few more points.
*18th Nov ’13 – Gravity at 1013 this is more like it, a couple more points and I’ll be happy.
*20th Nov ’13 – Gravity at 1008! Makes this 10% which is quite a big beer and about 2% stronger than planned 😀
*Bottled 30th Nov ’13 – with about 75g white sugar, my scales were messing me around, tastes strong and traditional, good dark straw colour. It actually finished fermenting at 1006.5 making it 10.2%!
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.
Cheers
