Notes

https://beerandbrewing.com/anastasias-dark-heart-russian-imperial-stout-recipe/

Mash at 150°F (66°C) for 60 minutes. Boil for 120 minutes. Add the molasses in the last 10 minutes of the boil. Caramelize the table sugar on the stovetop, cool it to room temperature, break it into chunks, and add it to the primary before you pitch the yeast. Ferment in the high 60s to low 70s Fahrenheit (low 20s Celsius) for 30 days. Move it to secondary fermentation for 90 days.

One liter starter of White Labs WLP007 Dry English Ale Yeast

BREWER’S NOTES
This recipe goes nuts when fermenting. I typically lose 15–20 percent of the batch out of the blow-off tube when it’s in the primary fermentor. I force carbonate and then bottle with a counter-pressure filler. I’ve had mash efficiency as low as 35 percent on this, so make sure you’re adjusting for your own system.
