Deuchars IPA – www.caledonian-brewery.co.uk
Time to pop my Cherry, Started at 8.30am, the Mash is now on at 9.20am 🙂 I’m going to do a 90 minute Mash and a Boil of 60 mins… which should hopefully time well with the Bacon & Egg butties for breakfast with the other half 😉 *so we can actually use the cooker and grill ‘cos its not got a fecking huge pan on it!* 🙄
I’ve just slightly over estimated my grain weights to be on the safe side as have I with the Batch Sparge volumes using DaaB’s Batch Sparge Calculator.

Fermentables:
Maris Otter Malt 2180 grams
Crystal Malt 105 grams

Hops:
Fuggle 9 grams @ 60 mins (FWH)
Aurora 9 grams @ 60 mins (FWH)
Willamette 9 grams @ 15 mins
Bobek 10 grams @ 5 mins
Fuggle 9 grams @ 5 mins

Copper Finings:
Protafloc Tablet – Last 15-20 Minutes

Predicted stuff:
Final Volume: 12 Litres
Original Gravity: 1.043
Final Gravity: 1.010 *final reading was actually 1010*
Alcohol Content: 4.2% ABV
Total Liquor: 18.5 Litres
Mash Liquor: 5.7 Litres
Mash Efficiency: 75 %
Bitterness: 33 EBU
Colour: 15 EBC

The Mash:
Recipe done in BeerEngine software www.practicalbrewing.co.uk and notes scrawled!
The original recipe came from www.hopandgrain.com
Most of the ingredients from www.barleybottom.com

Pre-heating the Mash tun with hot tap water, good pinch of Sodium Met treating the Hot tap water in the FV

Grain Temperature 18.5 Deg C

The Maris otter malt and Crystal Malt

Water at Strike heat and Grain ready to mash

Strike Temp, tweaked with a dash of boiling water as I decanted from the boiler with a jug and lost a few degrees

Starting Mash Temperature, Mash to last 90 minutes

All tucked up and monitored with a cheap Fish Tank thermometer from Dealextreme.com 🙂

Wort to the Copper:
End of Mash period, I actually went 15 minutes over the planned 90mins

Mash topped up and stirred ready for first runnings

First runnings, which are returned to the mash until it runs clearer (Which was at least 3 Litres)

Filling FV before transfer to boiler (Think you’d call this an Under-back)

Hops all weighed out, First Wort Hops, 15min hops, 5 minute hops and half a protafloc tablet

First Wort Hops with boiler filling

Spent grains

The Boil:
15 minute hop addition + Protafloc

5 minute Hop addition

The Wort (still hot)

Left overs (Still hot as I haven’t made an IC yet)

Safale s-04 Pitched once this had cooled down in the bath 🙂 Now its cooled I can really see the cold break forming as its gone all clumpy and is slowly settling.
All done, not bad for about 6 hours, not including cooling time as it will be a while sat in cold water in the bath 🙂
And all pretty stress free, I’m glad I have been doing some extract brews as its got me fairly confident with the boiling and hop schedules, the Mash was a piece of cake with no problems.

Lessons learned:
I need to do is calibrate all my buckets and my boiler pot.
It would be handy to have an IC.
HLT isn’t necessary for the moment.
Time to look into water treatment a little.
🙂

Mash details:
about 18-20 Litres collected @ OG 1022 / 62.1 Deg C

In the FV:
Final Volume was about right looking for my 12 litre brew length, maybe slightly more than planned which would probably be due to Sparge Volumes / 60 vs 90 minute boils.
OG 1026 / 72.8 Deg C *Actual OG is 1046, just a little higher than its supposed to be.

I think this makes my efficiency pretty good. 🙂

**Update** Bottled today 10th July 2009, tasted pretty good 🙂
