I am a lover of Imperial Stouts! (Before the latest Ukraine war, that style was named RIS for Russian Imperial Stout. The historical reason is a Russian Tsar loved that strong ale. Now, it is just an IS, Imperial Stout).
I have tried many Imperial Stouts. Some from the United States, some British, a lot of brewed in Poland. Imperial Stouts can be extremely strong (such as 11, 12, 13, and in one case 16% abv). They are the richest ales known if we are talking flavour. I will probably never be able to get the Dragon's Milk but two America's finest I know are "Speedway Stout" by AleSmith and "More than Jesus" (and similar) from EvilTwin Brewing.

Now,
@February: If you think Imperial Stout is weird, give the American Barley Wine a try! That's the strongest and richest Pale Ale known!
