Robust Wheat Porter – The Pancake Day of Homebrews! I’m using up a load of bag-ends, so my base malts (Lager & Wheat) are now totally depleted.
I’m not too fussed if its something odd-ball, it should hopefully be entertaining and I can start from fresh malts for subsequent brews.
Fermentables:
Wheat Malt – 44.9%
Lager Malt – 26.6%
Munich Malt – 5.9%
Jaggery (Cane) – 5.5%
Brown Malt – 3.7%
Chocolate Malt – 3.7%
Rauch Malt (Weyermann) – 3.2%
Amber Malt – 2.6%
Peat Smoked Medium – 1.8%
Munich Type II (Weyermann) – 1.4%
Roasted Barley – 0.7%
Oat Husks – 3% (This works out at 103%, added after calculating recipe)
Hops:
Bobek – 4.5 % @ 60 mins – 408g
Saaz – 4.15 % @ 0 mins – 48g
Final Volume: 23 Litres
Original Gravity: 1.077
Final Gravity: 1.016
Alcohol Content: 8.1% ABV
Mash Efficiency: 70 %
Bitterness: 181 EBU – (This is going to be bogus, the hops are old and like confetti)
Colour: 148 EBC
Mash: 90mins @ 67°c
Yeast: Safale US-05 skimmed from last weeks brew before I dry hopped it
Liquor Treatment: General Purpose copied from AG#55
The Malts, I added a few Oat Husks as a precaution:
408g of Bobek Hops in the copper:
Recirculating the first few jugs from the mash tun until it runs clear:
Jaggery Goor, or Unrefined Cane sugar:
In go the late Saaz hops:
Quite a lot of spent hops left in the copper:
I ended up with 1079 so liquored back 0.54L to 1077, I feel a few things worked in my favor to get the right OG and 21.46Litres:
- Predicted Mash efficiency be set low.
- The 3.7L bellow the Mash Tun’s false bottom which I usually deduct from the first sparge.
- 80c second (technically first) sparge, I normally go for 78°c, and 15min rest before running off.
All cleaned up and yeast pitched, I expect it to kick off quite soon and spew all over the kitchen floor, the fermentation fridge is still full of Brown Ceas which I just dry hopped.
*25th Mar ’13 – The fresh yeast has taken off well, still in the bucket… just!
*31st Mar ’13 – Gravity at 1018 so this has been pretty fast at fermenting, and it tastes rather good with quite a bit of smoke and the Brown/Amber/Choc malts definitely playing their parts, bitterness is coming through but not overly 
*7th Apr ’13 – Gravity at 1018 still so chilling it down before bottling sometime next week.
*Bottled 10th Apr ’13 – with 76g White Sugar, tastes bloody good too

Amber Motueka – I should really be brewing for a Twitter #BlackIPAoff beer swap with @Broadfordbrewer & @BrotherLogic but I decided to use up the end of a sack of Lager Malt and use some of the wonderful Motueka hops I have stashed in the Hop-Freezer. Motueka works rather well as a dry-hop so I’ll be using up the remainder of the bag once initial fermentation has died down.
This will ‘hopefully’ be a nice Amber coloured Hoppy IPA-like beer with a nice malt presence and a firm smooth bitterness.
Fermentables:
Vienna Malt (Weyermann) – 40%
Lager Malt – 37.2%
Wheat Malt – 16%
Cara Aroma (Weyermann) – 3.7%
Cara Munich Type III (Wey – 3%
Hops:
Motueka (B Saaz) – 13.8 % @ 60 mins – 20g (FWH)
Magnum – 14.5 % @ 60 mins – 10g (FWH)
Motueka (B Saaz) – 13.8 % @ 15 mins – 20g
Motueka (B Saaz) – 13.8 % @ 0 mins – 40g
Dry Hops:
Motueka (B Saaz) – 20g (or whatever is left from the 100g packet)
Final Volume: 23 Litres
Original Gravity: 1.049
Final Gravity: 1.012
Alcohol Content: 4.8% ABV
Total Liquor: 33.3 Litres
Mash Liquor: 12 Litres
Mash Efficiency: 75 %
Bitterness: 55 EBU (Utilisation set to 25%)
Colour: 39 EBC
Mash: 60mins @ 66c
Boil: 60mins
Yeast: Safale US-05
Liquor Treatment: Burton Pale Ale using the Graham Wheeler treatment calculator
HLT temperature:
Some of the malts:
Gypsum (Calcium Sulphate) being weighed out:
First Wort Hops and a small Sodium Chloride (Salt) addition in the Copper:
Flameout hops and half a Protafloc tab, it ran off pretty clear so 1/2 is all you really need for 5 gallons:
Hops steeped for 20-30mins with an occasional stir:
Target of 1049, near enough:
Wort dropping from copper into fermenting vessel, given a good thrash with a paddle and dry sprinkled the yeast:
A wide shot of running to fermenter, the all important clock in the background:
A no fuss brewday, everything works, hit gravity, yeast pitched, put to bed in the fermentation fridge for the first time!
Safale us-05 has a temperature range of 15-24c so I’ve set the cooling to come on at 24c and left the heating turned off so it can increase in temperature naturally.
*12 Nov ’11 FG 1012 reached, loose Dry Hopped with 20g of Motueka and set the fermentation fridge to cool to 17c.
*Bottled 18th Nov ’11 with 75g white sugar, tasting nice, nothing over-powering just nice.
*23rd Nov ’11 – About 1 week bottled taster, fruity with sweet malty bits, good mid-to-light-amber colour (Just been eating chocolate so maybe not the best pallet cleanser), maybe not the IPA-esque beer I was after but tasty, bitterness is smooth and pallet-coating. This beer would make a very nice Belgian ale with the appropriate yeast.
*1st Dec ’11 – now its had a bit more time in the bottle its drying out and the bitterness is coming through, its a lovely smooth bitterness. I’m happy with the results.
*17th Jan ’12 – This is a bloody good beer now
AG#55 – Imperial Smoked Porter

Imperial Smoked Porter – This is serving a couple of purposes; First is a Trial run of a big beer in my newly finished False bottom Mash tun; Second is using up some odd bags of malt and some older hops I had in the freezer and some other part bags of hops.
I’m not expecting the stated bitterness from my hops – http://www.wellhopped.co.uk/Product.htm so I’m going semi-worst case scenario and adjusting AA for age and storage.
Fermentables:
Pale Malt – 70.2%
Caramalt – 8.2%
Peat Smoked Malt, medium – 4.2%
Amber Malt – 3.9%
Oat Malt – 3.5%
Chocolate Malt, Pale – 2.3%
Crystal Wheat Malt – 2.4%
Chocolate Wheat Malt – 1.8%
Flaked Wheat – 1.6%
Chocolate Malt – 1.5%
Flaked Rye 0 EBC – 0.5%
Hops:
Bobek – 3.7 % @ 75 mins – 124g (FWH)
Admiral – 12 % @ 75 mins – 19g (FWH)
Herkules – 15.8 % @ 75 mins – 35g (FWH)
Brewers Gold – 9.1 % @ 10 mins – 68g
Cascade – 5.5 % @ 0 mins – 29g (Flame-out Steep for 20mins)
Saaz – 3.8 % @ 0 mins – 33g (Flame-out Steep for 20mins)
Simcoe – 12.9 % @ 0 mins – 20g (Flame-out Steep for 20mins)
Final Volume: 23 Litres
Original Gravity: 1.076
Final Gravity: 1.021
Alcohol Content: 7.2% ABV
Total Liquor: 36.8 Litres
Mash Liquor: 20.5 Litres
Mash Efficiency: 70 % (I collected 32L @ 1055 so hit efficiency but had too much liquor)
Bitterness: 121 EBU (I’m not expecting this as the bittering hops were fairly old so subtracting 30% from the AA will be more like 90EBU)
Colour: 140 EBC
Mashed for 90mins @ 66c
Boil for 75mins
Liquor treatment as per GW calc for General Purpose
Bigger bucket than normal with 8.5kg of malts:
New mash tun full of hot liquor:
Initial Mash a little high, cooled with cold liquor to 66c:
Tidy brewsheet (version 3, other two are scibbly works in progress) along with late hops:
Quite a heap of first Wort Hops in the copper along with the common salt addition:
What lies beneath, mash leftovers under the mash screen:
10 min hops going in:
Break material clumping in the copper:
Looks near as damn it to me (Showing 72 +2 divisions in the meniscus = 1076), not bad for a first outing of the new Mash Tun:
I had 3.7 Litres in the new mash tun to just cover the false bottom, the first sparge top-up was a little over 3 litres so I didn’t top-up and subtracted the difference from the Second batch sparge. This was to take into account the liquor under the screen, I ended up with 32 Litres in the copper which i thought too much but by the end of the 75min boil I was at my predicted gravity so I must have worked things out right!
Thoughts on the False bottom:
The mash ran off very well and after a few jugs of recirculating it was also very clear.
After stirring the second sparge and running off I came back to the mash tun to find it had run a load of malt particles into the copper as the last of the mash drained out. I’ll have to keep an eye on it next time to stop this just as it starts to show bits coming through, or have a go a Fly sparging so as to not actually disturb the Mash bed and hopefully limit the amount of malt particles coming through.
New cleaning game, poking bits of malt out of the perforated stainless!
16th May ’11
The usual, Stout+S-04 ferment :
*Bottled 25th May ’11 with 71g of White sugar and a tiny sprinkle of Nottingham yeast into each bottle as a bit of a safety precaution as it had dropped very bright. Finished at 1016-1018 so about 7.7% ABV.
*4th JUne ’11 Taster bottle, tasting good the Peat Smoked malt works well with the Strength of this beer, Bitterness just right so I’m glad I adjusted the hop Alpha acids for my older hops.

I just finished building my 45L Igloo Coolbox with Stainless False Bottom its been a fair bit of grinding with an Angle Grinder to make the right shape to fit the moulding of the coolbox, finished off in a few places with some 5/16th beer-line for a snug fit and to fix a corner I took a bit too much off, Its all spaced off the bottom with stainless cap screws. I could have fixed the corner and put Beer-line all round the circumference but had done enough grinding to make-fit.
Some of the tools used:
Drilled out Tank Connector with modified Elbow fitted so it is level with the flat base of the tun thanks to the coolbox moulding where the tap fits:
Stainless Steel Cap Screws used as stand-offs so about 25-30mm up from bottom:
Another Cap Screw in the centre to lift it out with:
Outside with Tank Connector & Ball Valve fitted:
False Bottom Fitted:
I had to give the Perforated stainless a good soak and scrub in Washing Soda to remove all grease that came on it.
I have to say this was easier than cutting and soldering loads of bits of copper pipe… Just needs a test run now! Maybe a BIG beer or a Parti-Gyle brew.

Yesterday I took the short trip over to Elland Brewery, West Yorkshire to meet Gordon the head-brewer for a proper chat after our first brief initial meeting at work (Saltaire Brewery). Elland use the same original Thwaites brewery yeast as we do at Saltaire.
The Mash Tun & Fermenters:
Gordon’s enthusiasm and excitement for brewing beer is very obvious and I thoroughly enjoyed a good few hours of nattering with him, tasting a few from their retained samples, and looking round their 10 Barrel Brew House.
My personal favourite sample was his Brewers Reserve which he’d dry hopped with New Zealand Motueka hops (Though not available in the shops, this was just an experiment) yummy stuff.
Gordon tells me that the plant originally came from one of the Firkin Brew-Pubs, with its all wood cladding and copper-domed boil kettle. He has a lot more technical know-how than myself with his Chemistry background, and is really got a handle on the entire brewing process with accurate process measurement and documentation and good practice procedure.
Gordon and the guys from Elland are not doing too shabby with their recent SIBA awards for the 1872 Porter, getting the 2010 Winter Gold and the 2011 National Gold. You’ve gotta love a full complex dark beer!

Hopefully Gordon is enjoying my Home brewed beers I left with him, you can catch up on his Tweets @GJMcKiernan

Building a 45 Litre Igloo Mash Tun
Each piece of the soldered manifold is made from 22mm copper pipe with un-soldered joints to allow disassembly and cleaning with a ‘cask tap cleaning brush’, the underside 1/3-1/2 of the copper tube is slotted with a 1mm Angle grinder disk.
The hole in the coolbox was made with a 21mm Q-max cutter, the tank connector was drilled out with a 15mm Blacksmiths drill (this would have been a lot easier with a Pillar drill and a Vice, but all I have is a crappy woodworking vice clamped to a wobbly table and a Cordless drill!)
Tools used were:
Pipe cutter
Solder, Flux, and Blow lamp
Round file
Flat file
Angle Grinder with 1mm Cutting disks
Scotch Brite pad
21mm Q-max cutter, with 8mm pilot drill
15mm Blacksmith’s drill
Cordless Drill / driver
Parts used were:
45litre Igloo coolbox
22mm Copper pipe
15mm copper pipe
6-off 22mm Equal Elbows
4-off 22mm Equal Tees
1-off 15x22x22mm Un-equal Tee
15mm Brass compression tank connector
15mm Brass Ball Valve
The Igloo coolbox which came from an ebay seller:
Some of the manifold pieces cut and arranged:
Soldered and separated:
Soldered and attached:
15mm Ball Valve tap fitted approx 11mm up from the inside base of the coolbox:
Cleaned manifold:
I found while fitting everything together that the Elbows were a bit more acute than 90 degrees which made it look all out of parallel, I fixed this by soldering it up with the removable end pieces on.
Everything was filled clean of burrs inside and out, excess solder removed, then scotch-brite pad used to polish up the copper. A thorough clean with a mild soda crystal solution gave it a final internal clean out. I later added a short bent turn-down spout from the ball valve with a 8mm reducer soldered to it.

London Porterish – This is a bit of a user-upper / Christmas gift / Christmas beer / a beer I only recently tasted at a beer fest and thought was amazing (Fullers London Porter). So this recipe is based around the one in the Graham Wheeler book, though a touch of Wheat malt added for head and the mix of Crystal malts is using up odd ends of malt. Hops are Sovereign which I have never used before.
Fermentables:
Pale Malt - 3990g - 70%
Brown Malt - 625g - 11%
Crystal Malt - 340g - 6%
Wheat Malt - 285g - 5%
Chocolate Malt - 225g - 4%
Crystal Rye Malt - 170g - 3%
Crystal Malt, Dark - 57g - 1%
Hops:
Sovereign @ 60 mins - 56g
Sovereign @ 10 mins - 19g
Final Volume: 23 Litres
Original Gravity: 1.058
Final Gravity: 1.015
Alcohol Content: 5.6% ABV
Total Liquor: 34 Litres
Mash Liquor: 13.7 Litres
Mash Efficiency: 80 %
Bitterness: 33 EBU
Colour: 144 EBC
60min Mash @ 68c
60min Boil
Cooled to 21c before pitching yeast
Mash treated with General Profile in the GW water treatment calc
3g of common Salt added to copper at the end of the boil
Updates on my Twitter-T.watter page – https://twitter.com/pdtnc
Malts, Temp & Salt additions:
The three tier:
Waste of time checking pH as usual:
Mash efficiency 95.3%!:
First runnings being recycled, FWH & old yeast ready in copper:
10min hop addition:
StarSan-ing everything that will touch sterile clean wort:
My Mash was on at 8.05am
The Boil started at 10.30am
I collected 30litres @ 13.5 Brix
Cooling from boiling took 10mins & 44Litres of water to 33c, then 3mins more to 21c. The 44L was collected in the HLT @ 42c
Original Gravity was 1056 with hydrometer, 14.9 Brix with refractometer (1058, Bang on to recipe)
Started Run-off to FV at 12:00, taking it slowly probably took the best part of an hour.
The Wort & Hops were smelling lovely
*Bottled 17th Nov ’10 with 65g of Soft Brown Sugar Came down to FG 1020 ish, needs some age for the dark malts to meld into something lush

I’ve been pondering on this one for a while, I think this is going to make a good combo of Hops… with hopefully a slightly spicy edge from the Crystal Rye and some good maltiness. Thats the plan at least!
Nelson Brucker
Fermentables:
Pale Malt - 2740g - 75% (Actually 3650g as I weighed the total grain amount rather than the Pale malt!)
Crystal Rye Malt - 365g - 10%
Munich Malt - 365g - 10%
Torrefied Wheat - 180g - 5%
Hops:
Hallertauer Hersbrucker @ 60 mins 15g
Nelson Sauvin @ 60 mins 15g
Hallertauer Hersbrucker @ 15 mins 40g
Nelson Sauvin @ 15 mins 20g
Nelson Sauvin @ 0 mins 20g
Hallertauer Hersbrucker @ 0 mins 30g
Final Volume: 23 Litres – I’ve been going against my half batches a bit lately 
Original Gravity: 1.040 – (Actually 1.050 due to Pale malt mess up!)
Final Gravity: 1.010
Alcohol Content: 3.9% ABV – (Actually 5%)
Total Liquor: 32 Litres
Mash Liquor: 9.1 Litres
Mash Efficiency: 85 % – I’m starting out at 85% now rather than 75% (Actual Efficiency was 86.2%)
Bitterness: 42 EBU – (Actually 39 as I added 5 mins to boil to compensate a little)
Colour: 28 EBC – (Actually 30EBC, though it does look a nice colour)
Today’s malts:
Weighing out the salts:
Boring Mash shot:
Our hops today are…:
First runnings going into the copper with First Wort hops:
Copper about Half full, collected a total of 30L @ 10.2Brix = 1.039, 108% Mash Efficiency??!! I think I must have weighed something wrong?! Maybe an extra kilo of Pale if it looks like its going to be a 5.1% after the boil:
Weirdly I managed to hit 1040!:
Quite like this colour, its Beer coloured:
Pitched Safale US-05 at 22-23c
The post boil gravity was 1043 according to the Refractometer’s 11.2brix which should make the 4% beer I was aiming for if it finishes at 1012! (I’m a little confused about all this, should I really stick to 75% mash efficiency in my recipe software?)
1043 – 1012 x 0.129=3.999% ABV
*Bottled 22nd Sept ’10 with 75g White Sugar
