A much smaller set here. Most of them from Barclay Perkins.

Leaving aside the export beers, the rest all look like 8d per pint Stouts, with the exception of the one from Courage. Which looks like a classic 7d Stout.

Whitbread's Extra Stout is, at 9.16 lbs per quarter (336 lbs) of malt hopped a little more than the other standard-strength Stouts which vary between 5.5 lbs and 7.5 lbs. Unsurprisingly, Barclay\s two export Stouts were much more heavily hopped at 15 lbs per quarter of malt.

Talking of the export Stouts, they have pre-WW I level gravities. Which was a typical development. With the UK's punitive tax rates not applying to export beers, these tended to remain at the old gravity while domestic versions became significantly weaker. A good example of this which is still around today is Guinness. Extra Stout and Foreign Extra Stout had the same OG - 1075ยบ - until 1916. Now domestic Guinness is not much more than half the OG of the export version.

Apparent attenuation is below 70% in every example. Though the FG of IBS Ex (Russian Stout) would have been considerably lower after a couple of years of a secondary Brettanomyces fermentation.

Grists next time.
