Try this out if you really like smooth Porter's.
For real Porter lovers, this will lack the roasted kick!, but it is a good session beer and on for converting BMC people over to dark Ales. If you want to make it a robust Porter then just up the black patent to 6 and Roasted Barley to 8 ounces.
I liken this to Yeungling Black and Tan. It is a tad more of everything, but just as smooth. Actually smoother because it does not have that little weird "twang" that Yeungling has.
