I'm just covering 1840 to 1900. I haven't had the time/inclination to transcribe any more. Yet. There's another consideration: if I put too much in each post, I'll be out of material by January. Stretching like an elastic band. Expect that.
You can see the explosive growth after 1850. What surprised me:
- sales increased in Ireland more quickly than in Britain
- in Ireland sales of Porter started behind, but soon outstripped, those of Extra Stout
- the tiny quantities of Porter exported to Britain.
- the difference between what Guinness sold in Ireland (mostly Porter) and Britain (almost exclusively Stout)
That interests me, if no-one else. It's worth bearing in mind, that the London Porter breweries were still brewing far more Porter than Stout at this time. Guinness deliberately aimed at the top end of the market.
I'll post again when I've extracted some more numbers from David Hughes' book. 1922 to 1930 will attract particular attention. After Irish independence, beer imports to the United Kingdom jumped from 7,017 barrels to 1,392,576. Any guesses how much of that was Guinness?
