Imperial Stouts?

Bourbon County is all you need to know.

 

Founders Imperial Stout is a terrific RIS that is easily obtainable during the winter and relatively inexpensive.

 

as far as availibility atm for bourbon barrel aged stouts I would say try some barrel aged boris by hoppin frog. It is year round and one of my favs. Also there is duclaw's retribution which has the added benefit of being only 13$/22oz and is 11.5%

 

Dragon's Milk by New Holland is one of my favorite readily accessible BBA stouts. Not sure what the distribution is like in PA though.

 

Central Waters Bourbon Barrel Stout is great as well. Try and find that.

 

stone RIS and DG Yetis are solid

 

Yeah, this is the one that popped into my head as well. I think I prefer Central Waters BBS but I doubt they distribute to Penn, and it's out of season now anyway.

+1 for Dragons Milk, obviously BCBS as well, and if you can find it, Dark Hollow by Blue Mountain. They're based in central VA but I don't know what their distribution is like.

 

Stone IRS and Oskar Blues Ten Fidy are my go to shelf RIS.

 

Peche Mortel isn't barrel aged but it is fabulous, as is Old Rasputin and even easier to come by. Alesmith Speedway is also great stuff.

 

+1 for Oskar Blues Ten Fidy and Dragons Milk, its not BBA but try Plead The 5th by Dark Horse if you can!

 

For PA I would say:

Victory Storm King
Sierra Nevada Narwhal (Oct-Dec)
Stoudts Fat Dog
Founders
Dogfish Head Palo Santo (they call it a Brown Ale)
Oskar Blues Tenfidy
Founders KBS (look for it soon and fast)

 

Central Waters Bourbon Barrel Stout might be what you're looking for but a few

others that should be much easier to find are:

Founders Imperial Stout (a little on the hoppy side for me but still good), Old Rasputin,

and I have loved Chocolate Oak aged Yeti (the older the date of production, the better it is, IMO).

 

Great Divide barrel aged yeti

 

weyerbacher Heresy is quite good.

 

Ale Smith Speedway Stout
Stone Imperial Russian Stout
Prairie Pirate Bomb / Prairie Bomb
Founders KBS
Samuel Smiths Yorkshire Stingo
Mike Hess Brewing Umbrix
Great Divide Yeti (any of the Yeti Stouts are solid)
Port Old Viscocity

 

They also do have a BBA that I have yet to try but really want too!
