Kyler Serfass, manager of Brooklyn Homebrew, shared this recipe as part of Epicurious' homebrewing primer and how-to videos. Cascadian dark ales, which are also called India black ales or Black IPAs, are dark hoppy beers that are growing in popularity among homebrewers.
Cooks' note:
The Final Gravity should measure approximately as low as 1.003, or as high as 1.020 depending on the recipe used. If there is no measurable change for at least 3 consecutive days, fermentation has most likely finished.
