Attenuation(points) vs Time(days)
| Sun August 16, 2009 20:30 | Kegged both batches today, and a bit of yeast to the kegs for conditioning purposes. One batch had a lot of acetaldehyde with the other it was not detectable. |

| Sun August 09, 2009 10:21 | Gravity reading[SG]: 1.014, Temp[C (F)]: 20.00 (68.00), Atten: 72.32%, ABV: 4.85% | Switched to the second fermenter which seems to have attenuated a lot more than other one. Other fermentation still shows signs of some renewed fermentation after stirring yeast back up into suspension |
| Sat August 08, 2009 10:11 | Gravity reading[SG]: 1.020, Temp[C (F)]: 19.00 (66.20), Atten: 59.81%, ABV: 4.01% | Seems to have almost stopped. A little bit of acetaldehyde detected. Gave it a stir to get the yeast back in suspension and finish the job off. The yeast character is really starting to come through now. With hint of coffee and vanilla. |
| Thu August 06, 2009 20:08 | Gravity reading[SG]: 1.021, Temp[C (F)]: 19.00 (66.20), Atten: 58.55%, ABV: 3.92% | Ringwood yeast character is really starting to come through. |
| Wed August 05, 2009 09:15 | Krausen seems to have built back up again. This yeast is a very strange beast. I will give it a stir to ensure it ferments out in a day or two. |

| Tue August 04, 2009 13:44 | Gravity reading[SG]: 1.033, Temp[C (F)]: 19.00 (66.20), Atten: 34.36%, ABV: 2.30% | Still fermenting but slowed down already. Bumped it up 1C |
| Mon August 03, 2009 09:05 | Seems to have started without too many problems. |

Not too bad but not the best one to date. Seemed to go down alright at Ian's weding though. |
