Here it is. The first installment of JW Lees beers. From my recent visit to the brewery to look at their brewing records.

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?

A couple of points spring right out.

Firstly, the much smaller range of beers being brewed. A Pale Ale, two Milds one Stout and a Strong Ale. And the Strong Ale seems to have been discontinued after 1904.

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.https://blogger.googleusercontent.com/tracker/5445569787371915337-5419239303476310556?l=barclayperkins.blogspot.com
