Ridiculous levels of detail. That's what I'm good at. There's going to be plenty of it as we browse through 80 years of Lees brewing records over the coming weeks. What fun we'll have.

Because I'm such a generous and thoughtful bloke, this time I'm throwing in a bonus table of Whitbread beers from the same time. So you can compare Northern and Sourhern beers at your leisure.

I got all excited when I spotted "C" Ale in the logs. It's a Manchester-specific type of bottled beer that appears to have left no ripples in the pond of history, save for a few labels. No-one seemed to have any idea what it was, other than quite strong. Well we do now. Have an idea of what it was. How would I describe it? Like a bottled Burton. Or a weakish Old Ale. Something like that. Dark and reasonably well-hopped.

Before you look at the tables, I've one last remark. One of the main effects of WW II seems to have been a standardisation of beer gravities. Something similar - but more extreme happened at the end of WW I. When prices were fixed by government depending on the gravity of the beer.

First the Lees beers:

Whitbread brewing records held at the London Metropolitan Archives

Now let's taking a closer look. A ridiculously-detailed look. As warned.

First the 1948 ordinary Bitters:

1948 Lees Bitter 1038, 0.95 lbs hops barrel, 86% pale malt, trace of black malt, 12% sugar, 2% enzymic malt
1948 Whitbread PA 1034.4, 0.81 lbs hops barrel, 79% PA malt, 10% crystal malt, 11% sugar

Surprisingly, Lees Bitter was stronger and more heavily-hopped. Though, taking into account the differing gravities, the hopping level is about the same. More significant is the lack of any crystal malt in Lees Bitter.


Now the 1948 ordinary Milds:

1948 Lees K Mild 1028, 0.65 lbs hops barrel, 80% pale malt, 1% black malt, 4% crystal malt, 13% sugar, 2% enzymic malt
1948 Whitbread XX Mild 1027.7, 0.80 lbs hops barrel, 55% PA malt, 26% mild malt, 8% crystal malt, 11% sugar

These are much closer in profile. The gravities are near identical. The Lees is hopped a little less. And it also had only half of the crystal malt of Whitbread XX. But one of the biggest differences doesn't show up here: the colour. I know from later logs that K was only about 30-35 EBC. Whitbread XX was 80 to 90 EBC.


1950 ordinary Bitters:

1950 Lees Bitter 1041, 0.90 lbs hops barrel, 87% pale malt, trace of black malt, 11% sugar, 1.5% enzymic malt
1950 Whitbread PA 1041, 1.08 lbs hops barrel, 81% PA malt, 9% crystal malt, 10% sugar

The two beers now have exactly the same gravity.The biggest difference remains the lack of crystal in the Lees. Which is also hopped a little more lightly.


1950 ordinary Milds:

1950 Lees K Mild 1031, 0.74 lbs hops barrel, 84% pale malt, 1% black malt, 4% crystal malt, 10% sugar, 2% enzymic malt
1950 Whitbread Best Ale 1031.7, 0.90 lbs hops barrel, 84% mild malt, 7% crystal malt, 9% sugar

Another two very similar beers. Just a few more hops and more crystal in the Whitbread. And, of course, the base malt for Whitbread was mild ale malt.


There are a few generic differences. Like Lees use of a small quantity of enzymic malt. The sugar options differed, too. Lees going for a mix of glucose, invert and proprietary sugars. Whitbread used mostly No.1 and No. 3 invert.

Was that detailed enough? Hang on. I haven't got into the mashing schedules yet. I've already more than enough today. Perhaps tomorrow.https://blogger.googleusercontent.com/tracker/5445569787371915337-4732519290433934689?l=barclayperkins.blogspot.com
