Delicious Imperial Stout Recipe

Imperial stout, also known as Russian Imperial stout, was originally brewed in London for export to Russia. It was originally brewed with a higher gravity and more hops than other stouts in order to withstand the long journey to Russia and to also provide a more robust flavor that distinguishes it from many of the other stouts. The story goes that Catherine the Great and Peter the Great were both fans of this strong, dark beer, and as a result, it also became popular among the Russian nobility of the time.

The term “Russian Imperial stout” is believed to have been coined by the brewery that first exported the beer to Russia in the 18th century. It is known for its bold, roasted flavors and a full-bodied mouthfeel more so than dry stouts and porters. It is a complex and flavorful beer that pairs well with a variety of hearty foods.

Hops – Galena adds bitterness, as well as some earthy, spicy, and pine-like flavors. It is important not to use too much Galena as they can result in a harsh, astringent bitterness, use them in moderation and in combination with other hop varieties. East Kent Goldings provides a nice balance of bitterness and earthy, floral flavors, while Fuggles add a hint of spicy, woody flavors.

Yeast – For this imperial stout recipe, we prefer to use an Irish ale yeast as it ferments cleanly and allows the malt and hop flavors to shine through. It also has a moderate to high attenuation, which helps to dry out the beer and balance the sweetness from the malt. Other yeasts that could be used include British (English) ale yeast or American ale yeast. When choosing a yeast strain use one that will ferment well at the intended temperature range and produce the desired flavors for the style of beer.

There are many brands of yeast available on the market that make a suitable choice for brewing imperial Irish stout. Some of the more popular options include White Labs Irish Ale Yeast, Wyeast Irish Ale Yeast, and Fermentis us-05 will also work well.

Some things to consider when choosing a yeast are its attenuation level, flavor profile, and temperature range.
