Breaking down the English hops, most were from Kent, with Mid-Kent dominating. Rather fewer from East Kent, but that’s to be expected. That was the source of the best-quality hops, which tended to be reserved for more expensive beers, such as Pale Ales. Second most popular were hops from Worcester, a region more analogous in quality to Mid-Kent. And, finally, a couple of examples from the relatively small district of Sussex.
Top dog amongst the foreign hops was the USA, with 8 examples. Bohemia and Germany managed a couple each. Followed by single examples from Alsace and Belgium. Though I suppose the former was technically part of Germany at the time.
As for age, most were reasonably fresh, never more than a couple of seasons old. With the one massive exception of 10-year-old Alsace hops in the 1906 Barclay Perkins X Ale. You have to wonder what the point was of using such ancient hops.
