The general public tends to seek the refreshing thirst quenching of beer, while enthusiasts tend to seek the strong flavor of beer. Stout, which is at the top of the heavy flavor genre, is a beer style that has been interpreted into the most subdivided genres, and it is the Imperial Stout that pushes the heavy taste of Stout even more extremely.
Although the Imperial Stout originated in England, the empire in the name does not refer to the British Empire, but only to the Tsar**. This beer is a fortified version made for export to **, hence the name Russian Imperial Stout. When it comes to this beer, there is one person who is inseparable from the famous Empress Catherine Catherine II, and during her reign, a shrewd merchant wanted to sell Stout from England to Russia. Increasing the alcohol content is an essential improvement, not only to conform to the drinking habits of the Russians, but also to prevent the beer from freezing during transport through the cold regions of the Baltic Sea.
This beer was so popular with the empress that it became popular among the royal family and aristocracy, and the empress used it to reward her victorious generals in many foreign wars. Now, the term empire has also been extended to other beer styles, becoming a prefix for more ingredient inputs, more intense versions, such as Imperial IPA, Imperial Pilsner, and so on.
