HSB was my drink of choice - problem was not many pubs in Soton sold it.
Brewed by Gales in Horndean (dangerously close to Skatesmuff), The Bay Tree (long time closed now) near Solent Uni was just about the only place in town. Quite a few places out in the sticks such as Romsey, Hamble etc sold it as well. I think Gales may have been swallowed up by one of the bigger brewerys as it certainly doesn't seem to taste as good as it used to.
Many a brain cell destroyed by HSB, at 5.4% it had a pretty strong kick to it, but tasted great.
