I'd add that hops of the same variety vary noticeably not just from different years (seasons) but from different farms and regions due to local terroir. Despite being a small island north of the Isle of Wight, and adrift in the north Atlantic, with a fuzzy-haired posh lunatic at the helm, Britain is remarkably diverse in terms of geology and other environmental conditions. I quite like Goldings and I've had batches from a number of different farms and from different seasons from the same farm. The variation is not insignificant and I'd agree comparable recipes with the same hop variety grown in different terroir produces distinguishable ales. Factor in too the different hopping practices at different breweries and the 'same' beer brewed across Britain might vary considerably without considering yeast strain. Fact is, if we gave two brewers the challenge of brewing the same recipe and provided exactly the same ingredients to both, including water and yeast, they'd likely produce different beers. And why attempting to exactly match a specific standardised commercial beer is more likely a hopeless challenge. But it's fun trying.Well, I've started something here that needs a bit of explaining. I can't find the original quote that I've probably badly paraphrased. There should be no doubt that yeast can make a massive difference to any recipe in many ways, most obvious perhaps being different yeasts differentially favoring hop or malt. Of course, there are many other differences, but the only specification for yeast in Graham's recipes I can remember was for either top fermenting or bottom fermenting, not implying different strains didn't produce different results, more that the specific yeast usually couldn't be obtained.
What I believe Graham meant was that recipes used by British brewers (in particular for pale ales and bitters) were very much alike for the grist, and even with different barley strains, differences weren't necessarily noticeable while hop selection does.
My last 3 brews (pale ales) had more or less the same grist. The first was mostly Goldings, the second mostly First Gold and the third with Northdown early and Bramling Cross late. Yes, there were other similarities, all also with the same yeast and water profile, and while they looked similar, instantly the aroma and impact on taste senses were quite different.
Sorry if I've caused some consternation and perhaps wrongly represented Graham's grand writings, this was not my intention. I will say that fermentation temperature control is frequently used to restrain the better qualities of many ale yeasts. I can understand lager yeasts being held at low temperatures, but ale yeasts so restrained? Below is an extract from a brewery record from 1961 showing fermentation temperatures and gravities against time. What I, not Graham, will suggest is that even using specific yeasts, the outcome is dependent upon how it is controlled and treated.

Edit: I forgot to mention that British hops was once a very big industry, using up much acreage across the land.
