Guinness in the 1930's

Still not finished with my anti Guinness wiping out British Stout theory. More numbers, I'm afraid.

It's great having such detailed information for Whitbread. It means I can check whether Guinness was replacing Whitbread's out Porter and Stout. Let's compare the sales of Whitbread's own beers with their resales of Guinness and Bass.


Whitbread's output of Porter and Stout was very stable from 1933 onwards. As was the amount of Bass and Guinness Whitbread was selling, which hovered around 25%. I can see no evidence of Guinness replacing Whitbread products.

Though the overall quantity of Porter and Stout brewed was pretty stable, the quantities of each specific beer made varied considerably. The decline of Porter continued and in 1936 a newcomer arrived that began eating into London Stout's share: Mackeson. Whitbread had acquired the brewery in 1929 and the fact that they began brewing Mackeson Milk Stout at Chiswell Street shows the importance the product was acquiring.

But more about that tomorrow. I need to crack on with "Trips!".
