As with all, my list tends to change with mood and what I'm drinking lately. Three always on the list:
Anderson Valley - Hop Ottin
Others rotate more...I'll go with these two right now:
Founders - Old Curmudgeon
Odell - St Lupulin
Newcastle is the ultimate anytime session beer, if stranded on an island with only one beer that would be the choice. With that said, the others add lots of flavor to life. Frankly, I'll grab some of my homebrews (like the one I'm drinking) over any of these often.
