Notes

With this complex malt bill I want to taste this in all its glory, so no coffee, cocoa nibs/powder or vanilla extract. Just an Oatmeal Stout.
Smooth brew day. Left mash to Mash Out at 72c for about 30 mins. Efficiency jumped to 85%. Very pleased with this.
OG 1.054 15 litres Day 11 1.020. Long way to go. Upped temp to 18.5.
5 litres watered down with 4 litres of tap water OG 1.029. Predicting that will end up like a Mild. Will be interesting to see. Day 11 1.010
Weaker batch bottled after 14 days.

Remaining stronger batch did not finish off with bump in temp. Added more yeast and vanilla essence with high sugar content to try to get the yeast going...no movement after a week. Moved batch to bottling bucket and pitched more yeast. Finally 10 days later down to 1.015. 3 days later no movement and bottled. 26 bottles. Samples taste very good and chocolatey.
