Unfortunately, the ones I like best are seasonal or limited release. My very favorite is Founder's Breakfast Stout, but it is only available from October through January. It practically flies off the shelves here, so it's not easy to get. Looking forward to some KBS soon too.
I also really like Boulevard Milk Stout, but it's a tasting room series beer that was only released in a sample pack. I did hear that it is going to be sold on its own, but it will still be seasonal. It will be called Tough Kitty Stout and should release in September.
