London Mild before WW II

As before WW I, London tended to have stronger examples than more rural districts. The difference after WW I, was that the price was around the same for a beer of the same strength whether you were in London or the provinces.

While London brewers often had three Milds of different strengths: Ale at 1028-1030º retailing for 4d per pint, standard Mild at 1034-38º for 5d per pint and Best Mild at 1042-1044º for 6d per pint.

By far the most common of the three types was 5d Mild. The cheaper Ale was mostly brewed in tiny quantities. For example, in 1938 Whitbread brewed 4,237 barrels of LA, their 4d Mild and 216,200 barrels of X Ale, a 5d beer.

Not every London brewer produced all three classes of Mild. Whitbread, for example, only had a 4d and 5d version. While Fullers brewed a 5d and a 6d Mild, but no 4d. It probably depended on the types of pub a brewery owned.

In general, London Milds were quite dark – in the 80-90º L range. But there were still plenty of semi-dark examples. Barclay Perkins X and XX were both around 45º L as brewed, but there were also versions of both that were coloured up with caramel at racking time to the darker 80-90º L shade.

These are some examples of London Milds in the cheapest price class:
