I think the closest brew pub is going to be in Collegeville. That's down HWY 29 but probably 30 minutes away. There are closer bars to Greenlane but even though I am not far from there I don't hang out much in that area. The East End Alehouse in Harleysville isn't far from the competition (maybe 10 minutes) and has the following selections on Tap:
