Forget beer stores, head to Kane Brewing about 15 mins south of Monmouth/Long Branch and pick up some delicious fresh beers. Edit: I unfortunately do not know of any good beer stores in the area as I only head to Monmouth/Pt Pleasant to surf and have been for years. BUT Kane is not to be missed! Do yourself a favor and take the trip.
Would love to stop there again, but it's my grandpa's 80th birthday so I'll be doing family stuff during Kane's hours tomorrow. I wish I could get a growler of morning bell with cinnamon and maple. I could drink that all day.
Spirits Unlimited in Middletown is your place. Great selection and they do growler fills too so maybe you will get lucky with a Kane offering on tap.
