Comments:

This will be brewed with half the 2206 yeast cake from the Jamieson Bock - which is due to come out a little before 21 June. The other half of the cake will be used for "BockBock Bock".
This is intended for Oktoberfest this year.
Expecting this to be 3 weeks fermenting - to come out around 12 July.
----------------------------------------------------------------
Sun-21-June-2009
Dough in @ 44 degC and rest 15 mins
raise to 67 degC and mash for 60 mins
Ended up with too much wort in boiler - about 35 L
gravity before boil appeared to be 1.071, however after boil read 1.054. Dont understand how this happened.
Ended up with 29L of wort at 1.054.
Color appears quite clear, but also quite light
Cubed for the night, tomorrow will rack bock to secondary, and pitch yeast cake into the bent monk.
----------------------------------------------------------------
Mon-22-June-2009
Pitched 2 full cups of yeast from jamieson bock.
Racked from cube with a tube which was silly, should have let it drain and splash a bit for oxygen, but too late now.
Ended up with 25 Litres in the fermenter, and probably 3 or so litres of trub stuff at the bottom of the cube which I chucked.
Pitched @ 20 degC, but freezer is rapidly bringing it down to 10 degC where I will keep it.
Wouldn't want to be lifting much more than 25 litres in and out of the freezer regularly

Attenuation(points) vs Time(days)

Sun July 26, 2009 19:27	Gravity reading[SG]: 1.016, Temp[C (F)]: 14.00 (57.20), Atten: 70.91%, ABV: 5.23%	- final reading 1.016, probably not too bad - smells great, malty, tastes the same, pretty happy with this one
Tue July 21, 2009 11:09	Gravity reading[SG]: 1.018, Temp[C (F)]: 14.00 (57.20), Atten: 67.27%, ABV: 4.96%	- tastes quite nice, clean, malty - to critisize, it may be a little thin, or lacking big flavour - have to say though, it's looking promising - for a summer quaffer if nothing else - gave it a good stir with the spoon, in an effort to get another few points out of it. Noticed that the yeast is all kind of sticking together, and not really looking all that healthy. Will have to look at having a bit of extra yeast in future, to help finish it off properly. Don't want to end up under attenuated, which would spoil the whole thing.
Tue July 07, 2009 12:39	Gravity reading[SG]: 1.020, Temp[C (F)]: 10.00 (50.00), Atten: 63.64%, ABV: 4.69%	- quite nice and malty - nice orange color - can't really find a lot wrong, will be keen to see how this comes out of the bottle.
Wed July 01, 2009 16:03	Gravity reading[SG]: 1.029, Temp[C (F)]: 10.00 (50.00), Atten: 47.27%, ABV: 3.49%	- still tastes ok, reminds me a lot of the bock when it was fermenting - plenty of sweet ferment gasses in the freezer - will be interesting to see if any nice taste develops here, as I really can't see it going places.
Mon June 29, 2009 17:00	Gravity reading[SG]: 1.030, Temp[C (F)]: 9.00 (48.20), Atten: 45.45%, ABV: 3.35%	- doesn't taste bad, doesn't taste good, kind of take it or leave it this one - not sure if i can sense any apples there ? - could be boring.
Mon June 29, 2009 08:19	Gravity reading[SG]: 1.038, Temp[C (F)]: 8.00 (46.40), Atten: 30.91%, ABV: 2.28%	- didn't take gravity reading, but can smell fermenting - smells nice, sweet, think i'll just leave it untill the end of this week, and i'll take a gravity reading.
Fri June 26, 2009 09:22	Gravity reading[SG]: 1.038, Temp[C (F)]: 10.00 (50.00), Atten: 30.91%, ABV: 2.28%	- still not vigorus the fermentation, however appears to be going down - only just sensing the ferment gasses in the freezer - tastes quite nice, slightly malty, good potential
Thu June 25, 2009 10:56	Gravity reading[SG]: 1.054, Temp[C (F)]: 10.00 (50.00), Atten: 1.82%, ABV: 0.13%	- thick krausen present - no bubbling, or ferment gas activity yet
Mon June 22, 2009 16:18	Gravity reading[SG]: 1.054, Temp[C (F)]: 20.00 (68.00), Atten: 1.82%, ABV: 0.13%	Pitched 2 full cups of Jamieson bock yeast cake into 25L @ 20 degC Freezer rapidly bringing temperature down to 10 degC where I will keep it. Didn't manage to oxygenate, or splash the wort around much, so I'm not sure what effect taht will have.

Sat November 14, 2009 00:40	Rating: 40 Age at tasting: n/a	- Ady loves this one, me too, wish we had more than 1 bottle left.
Sun November 01, 2009 07:53	Rating: 40 Age at tasting: n/a	Just drank 2 of the last 3 bottles over the weekend. Has improved a lot over the past few months. Tastes absolutely fabulous. Have to brew this one again. - nice malty backing - clean - yummy
Sat August 15, 2009 18:24	Rating: 35 Age at tasting: n/a	- has a ferment residual aroma, which is not particularly pleasant - may be too sweet, i'm not sure what this is, because it did attenuate reasonably well. It's possible it may be diacetyl, as i detect a sort of butterscotch sweetness there. - it is reasonably pleasant to drink. - i would be interested to hear some feedback on this beer, as i really can't decide if it's any good. For me the sweetnes and initial ferment aroma are the most objectionable. - overall, not too bad, but don't expect raving results from this beer
