"Imperial Russian Stouts historically tend to be declared in the range of 9 to 10% alcohol by volume, at 10% Ridgeway’s is at the top of that range. What differentiates the style from simply a strong stout or porter is that extended ageing and perhaps a little judicious “infection” before bottling which makes them considerably more vinous and sharp than an export stout so there is MUCH more of a wine character than you normally get in a strong ale. Not soured but just that little nod towards a lambic beer. Very roasty and very bitter. That bitterness mellows over time in the bottle but if you are lucky enough to get an Imperial Russian on draught it will be full on. The style is not intended to be overtly hoppy once settled but obviously with so many hops used the draught experience will have something on the hop front that won’t be there in a bottled version.
Ridgeway’s Russian Imperial Stout will be brewed once a year. A small number of numbered bottles will be made available for you to enjoy immediately or to lay down for a while.”
