Imperial Stout

Brewed in eighteenth-century London for export to the Russian imperial court, this big, dark ale relied on high alcohol to survive the Baltic voyage, with Barclay Perkins a key producer. Intensely flavoured, it spans a wide range of balances and regional readings, showing roasty, burnt malt and deep dark or dried-fruit character. It runs a formidable 8.0 to 12.0 percent alcohol with 50 to 90 IBU and a 30 to 40 SRM colour. Modern American craft brewers turned it into a barrel-aged speciality, exemplified by Goose Island Bourbon County Brand Stout, Founders KBS, and Bell's Expedition Stout. BJCP catalogs it as 20C.
