I'd wondered how their beers would differ from those of the London breweries I've mostly concentrated on so far. Let's take a look, shall we?

|JW Lees brewing records|
A couple of points spring right out.
Secondly, the Milds are much weaker. I was Shocked to see a beer of around 1030 being brewed in this period. X Ale, standard London Mild was 1055 or so.
Thirdly, a much lower hopping rate. Lees B, which seems to stand for Bitter, had just 1.44 pounds of hops per barrel. Whitbread's 2PA, which had a similar gravity, had 2.14 pounds. Whitbread's Porter had 1.25 pounds, the slightly stronger Lees XXX Stout had just 0.82 pounds. I canj't make a comparison for the Milds as there were no London beers of similar gravity.
Fourthly, a higher degree of attenuation. Whitbread's Pale Ales were about 65% apparent attenuation and their Mild around 75%. Lees Bitter and Milds were all above 80%. Only the Stout had a similar level of attenuation as London beers.
So pretty significant differences from London. I can't say that I'm surprised as I hadn't really known what to expect. There will be more reports as I work my way through the records.
