Probably Due To Network Congestion

The Plan… to make a solid wholesome malty pint with English hops and a fruity Blackcurrant flavour & Aroma from Bramling Cross hops 🙂
I’m starting this brew off and getting all my liquor from my hot & cold feeds in the garage today, probably try and tidy up a little while the mash is on too. (Note to self B&Q Pushfits are crap, can’t get the buggers back off, glad I only bought one of them)

Bramling XB – (Bramling Cross Bitter)

Fermentables:
Maris Otter 2700 grams 60.8%
Flaked Barley 500 grams 11.3%
Brown Malt 500 grams 11.3% (Bag end from work which will hopefully balance the Blackcurrant of the Bramlings)
Munich Malt 500 grams 11.3%
Caramalt 200 grams 4.5%
Chocolate Malt 40 grams 0.9% (Just to add a little deeper colour)

Hops:
Challenger 20g @ 60mins (FWH)
Fuggle 30g @ 30mins
Bramling Cross 20g @ 15mins
Bramling Cross 20g @ 0mins for 80c steep

Final Volume: 23 Litres
Original Gravity: 1.042
Final Gravity: 1.010
Alcohol Content: 4.1% ABV
Total Liquor: 32.7 Litres
Mash Liquor: 11.1 Litres
Mash Efficiency: 75 %
Bitterness: 33 EBU
Colour: 46 EBC

Mash Temp aimed at 67c to keep some body
Yeast Safale s-04
1 Tsp Gypsum to Mash + 1 to boil
Mash on at 8.50am

Mash Start temp, not far off my aim of 67c:

First batch sparge just sitting before running off, and it ran off beautifully:

First Wort Hops (FWH) just going in on the first spargings:

80c Steep hops left for 30mins before cooling to 23c:

Dropped from a good height caused a heck of a lot of foam:

Aiming for 1042, so this is near enough for me:

Brewday seemed to go really easy, very relaxed, it seems having a dedicated area for brewing is going to smooth things out considerably… and I’m far from organised at the moment! 🙂
The wort was tasting pretty nice, though there were lots of roasted and biscuit aromas while the boil was on, will be interested how this one turns out, its a nice deep tawny copper/brown by the looks of it too :)

Bottled 25th Apr ’10 with 60g Sugar priming

Thoughts on cooling wort!
You use a 10-15 meter coil to make either a Counterflow cooler(CFC) or a Immersion cooler(IC)….
In the case of the CFC, could you slow down the flow of Hot Wort and speed up the flow of cooling water and thus reduce the length of your copper coil?
I’m just in the making of something that I think will speed up my Boil-to-Pitching temperature time even if it doesn’t entirely chill things down, mainly as an interim measure to either buying or making an IC, but also as a bit of an experiment…
🙂


The unequal T’s are 15x15x22mm from B&Q
The Spiral bit it a bendy tap connector also from B&Q
The Pipe is 22mm and there are a couple of 15mm bits in there too
…the other fittings are from Screwfix and just standard 15mm connectors.
I intend to restrict the flow of the 15mm down to 8 or 10 at the out-end.
Soldering it up, added a 15mm compression nut to attach to boiler and a 15-8mm reducer to restrict the flow.

I’ve ordered some bits, garden hose, Tap connector and hose quick releases.
I’m ready to go… Brewday today 🙂 while we’re off work.

Apparently its almost exactly the design of a piece of Chemistry equipment – Allihn condenser – http://en.wikipedia.org/wiki/Condenser_(laboratory)
🙂
***OK then…
****Well its just been tested!
Left the boiler to settle for 20 mins from boiling, hooked up my bits of copper pipe and garden hose and turned on the cold water.

At a sensible flow rate of wort it was able to cool to 55°C
At a slow trickle I can get it down to 34°C
I ended up with 13 Litres of wort @ 45°C in the FV (with lots of flow rate changes and temperature checks)
If I’d let it trickle it would have taken ages to empty the boiler so it had to sit in the bath cooling off some more.

Here’s the pics:


It does prove that if you were to gang 3 or 4 of these up you could probably get a lower temperature and a faster flow, but that goes against my simplistic idea, I’m now going to go buy a coil of 10mm copper pipe… 10,15,20 metres??? and make a proper IC coil! 🙂
