I've noted this down as being on hand pump at two pubs and I cannot find any reference to it anywhere. I may have written it down wrong but to do it twice is not like me. There is a laines area in Brighton so it's probably a local brew if it does indeed exist.
I'll stay on me own
Bit of a long shot, but could it be a rebadge of WJ King's Brighton Best?
Both pubs in question have had Brighton Blonde on so this maybe the case... Next time I see it I'll pay closer attention.
