I stumbled across a recent article in All About beer called "The Evolution of Dry Stout" by K. Florian Klemp.

I've seen worse articles on the history of Stout. But it pepetuates a particularly annoying myth. That at the start of the 20th century English Stout all went sweet. Sorry, two annoying myths. Also that Guinness has been highly attenuated and dry since the 1800's.

Here's what the article says:


"This is where the Dublin and London stouts diverged over the next few decades, according to some observers. Dublin stout, using the Guinness template, came to mean a marginally drier version, made only with pale and patent malt. The attenuation was largely due to the exclusion of less fermentable amber and brown malts. London stout, truer to precursors, used pale and brown malts, but often a bit of the newly minted patent malt and perhaps amber and crystal malt. Some brewers eschewed the patent malt altogether, relying on the traditional brown malt. Irish brewers often “gyled” theirs with a dose of lively, fermenting beer for conditioning. These ubiquitous, high-quality Irish and English porters and stouts became dominant beers of the 19th century."

And this:


"By the early 20th century, porter had essentially run its course in England and was replaced by stout as the dark beer of choice. Along the way, stout had also lost its meaning as a strong beer, but simply a black beer chiefly brewed in England and Ireland. The dry stouts contrasted greatly with sweet milk stouts favored at the turn of century. Sweet stouts became England’s preferred roasty beer, leaving Ireland chief domain of the dry version."

Pretty clear restating of those myths.

I was going to write a complicated article, comparing Guinness of various periods with English Stouts. Then I thought "bugger that". I'll just let the numbers speak for themselves. Here they are:

Tha apparent attenuation of the two samples of Guinness Extra Stout are 71.17% and 66.10%. Less than average of 72.91%. Of the 65 English Stouts, only 26 have a lower degree of attentuation than the most highly attenuated Guinness. 12 English Stouts have attenutaion greater than 80%., 2 more than 90%.

Draw you own conclusions. I'm off to drink a Guinness Special Export.
