I just got one from O'Briens- same BBE and batch number- I'm getting no chlorophenols or solvents (which would cause the aroma/flavours you describe)- a good smack of resinous hops on the nose with a burnt caramel malt. Intense bitterness in the taste with more of the burnt caramel. Astringent but with a good carbonation bite and a lingering bittering.
