Mash & steeping: The mash is acidified to a pH of 5.4 with phosphoric acid.
I'm assuming low efficiency because I use most of the second runnings either for another brew or for starters (and it's easier to control; i.e., stop sparging at the right point).
Between 15 and 17 gravity points should come from the table sugar and the rest from the malt, regardless of the actual percentages (i.e., the gravity without the sugar should be around 1.074). Different proportions will yield different final gravities. This proportion gets me the closest to the desired FG (~1.013 down from ~1.090), with this mash schedule.
Sugar: The dark sugar I use is made from the reaction of glucose with a specific amino-acid combination at high temperature and controlled pH. It is made in very small but super concentrated batches to avoid over-pyrolising the sugars. Colour is approximate. One could use a part dark candi syrup and a part sucrose (matching the colour) to get similar results.
Fermentation & conditioning: Pitching rate is possibly between 0.5 Mc/ml/°P and 0.75 Mc/ml/°P but not sure exactly (I've established it empirically based on how I grow my yeast, and I know that this yeast can take it, but other yeasts produce bad alcohols at this same pitching rate). Pitched between 18°C and 20°C in a well oxygenated wort. It is allowed to rise to up to ~21°C in the first 24 hours and up to ~24°C in the next 24 hours. After that it can rise up to 28°C with no problem. It is held at peak temperature for a few days until primary fermentation is almost complete. Then it is cooled down slowly for a couple of days and transferred to secondary and conditioned cool for ~6 weeks.
Then it is bottled with fresh yeast and conditioned warm for the first couple of weeks. Ready to drink after a few weeks in the bottle.
