Welcome to MD! Born and raised here, lived locally most of my life.
Just a novice here when it comes to brewing, 5 batches in. I'm planning on doing a pumpkin beer soon to have it ready for fall, may do a 10g batch since I have a feeling it will go quick with having friends over.
As far as supplies go, I get mine from Annapolis Home Brew off of Rte. 2 but I'm sure there is somewhere closer to where you are.
