Notes

Adjusted according to my needs

Here's original brewer's notes:

Brewing an imperial stout can be challenging. Here are some tips to help.

Pitch the yeast and let the temperature rise to 68°F (20°C) and hold that over the first 3 days. Raise the fermentation temperature gradually to the low 70s Fahrenheit (20s Celsius) to help the yeast complete fermentation and reabsorb any diacetyl that was produced during fermentation.

Be sure to check your gravity during fermentation to be aware of any potential fermentation issues and to know when you have reached your target gravity.

After 2−3 weeks in the primary, rack the beer off the yeast cake into a secondary fermentor for an extended conditioning period of 2−4 months. Purge the fermentor with CO2 if possible, and keep it in a dark area that has consistent temperatures in the low 60s Fahrenheit (mid teens Celsius).
