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 🙂

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.
