7d an Imperial pint was very expensive for 1908. A pint of standard draught Mild would only have set you back 2d a pint. And you were only getting that price if you bought thee dozen bottles. Which is quite a lot of such a strong beer. Though I'm pretty sure I could have got through them.
An Imperial pint of a beer over 10% ABV. What would the Portman Group say?
