This is done as a complex partigyle process by Fuller's which was not attempted to be recreated. It was noted that the commercial example has more of an "oversparged" flavor that was tannic whereas the clone did not have that flavor. The above recipe was voted not cloned by a 3-2 vote. It sounded very similar but others reported less malt profile and too much hop aroma. The bitterness of Fuller's was also described as "sharper" than the clone.
It is unknown at this time when a rebrew is scheduled, but Jamil suggested using a partigyle to recreate both the ESB and London Pride.
