My favorite domestic brews come from Stone Brewing Company.
My fav from them is :
Arrogant Bastard Ale, which is technically an IPA, but at 7.2% alc/vol and some serious hop mixture, it is full bodied. Did I mention it is dark? Not black dark, but certainly not pale by any means. Double Bastard variety is 10%, and I swear to god you can taste the alcohol, like it was a weak shot...
I've also had this on its original release date:
Imperial Russian Stout. Talk about a serious brew! 10.5% alc/vol, thick enough to pass specs as road tar in 35 states. Damn tasty stuff.
Last but not least,
Smoked Porter. Yep, bought a case of this a while back. Yep, it tastes smoked, and I liked it, but I can see how it is a brew not fit for everyone.
The above come in 22 oz bottles, 12 to a case, IIRC
