2. Origins of imperial stout? • Russian imperial stout came into being at the end of the 17th century • Peter the Great enjoyed porter in England and asked for it to be shipped to the imperial court of Russia • The porter went bad before arriving in Russia • Alcohol, malt and hop content was increased until it could survive the journey and creating the first imperial beer @AnigelUK
3. Origins of imperial stout? • Peter the Great came to England around 1697 • He was back in Russia by 1698 and died in 1725 so is unlikely to have ever had Porter let alone ask for it to be imported • Barclay Perkins starts exporting porter to Russia in 1797 • The Barclay’s porter was the strongest version they brewed and became known as Russian Imperial tout • It continued to be brewed with only minor recipe changes right up to 1990 by Courage then another Southwark brewer @AnigelUK
4. Style overview An intensely flavoured, big, dark ale with a wide range of flavour balances and regional interpretations. Roasty-burnt malt with deep dark or dried fruit flavours, and a warming, bittersweet finish. Despite the intense flavours, the components need to meld together to create a complex, harmonious beer, not a hot mess. 20C Imperial Stout @AnigelUK
