A nice blend. It's sort of the inverse of Fillmore, with Fillmore being a deep, dark, creamy blend, and Stratford being hay-like, grassy, a light affair. One of my peak experiences with the pipe was 2003 or 2004 Stratford on a really, really hot day in Chicago in 2007. This was back when you could buy 3-4 year old GLP tins on the shelf at Iwan Ries.Another good one IMO for a first is G.L. Pease Stratford.
Another tangent: the GLP Classic Collection is supposed to be sort of impressionistic sketches of old blends. Abingdon is a take on 759, Charing Cross on BS White, I think, and Kensington perhaps a take on State Express London Mixture. Anyway, I read this one theory that Stratford is a take on Dunhill's Elizabethan Mixture, and that the name leaves a hint: Stratford is where Shakespeare's plays were performed, and Shakespeare wrote in the Elizabethan era. Not sure about the efficacy of this, or the verity, but it seems close to logical. And reading the tasting notes for older Elizabethan, it seems in the same ballpark as Stratford.
