I won't pretend that there's going to be any great excitement in this stuff. Oh, one thing I forgot last time. Did you notice how after 1950 the gravity never fell below 1030. There's a very good reason for that. The way duty was calculated changed in that year. Until then, there was a flat rate charged per 36 gallons of up to 1027 gravity, plus an additional amount for every degree above 1027. In 1950 that was changed to a gravity of 1030. It meant that you paid the duty for a beer of 1030, even if your beer was just 1027. It made brewing a beer below 1030 financially unattractive.
Which begs the question, had the rules not changed, would Whitbread have continued to brew a sub-1030 Mild. And was the rule changed designed to bump up the gravity of the weakest beers to 1030?
You can see that Whitbread's stronger Mild, XXX, didn't last long. Introduced in 1954, it was discontinued in 1955. But not before the gravity had been cut from 1037.5 to 1034.8. The mid-1950's was when stronger beers of various kinds were introduced. Mostly they were stronger Bitters, but there were some Milds, too. Presumably sales of XXX didn't take off. Then again, that was exactly the period when Mild's decline began. You can notice the fall in demand from the batch sizes. Until 1951 Whitbread brewed their Mild in batches of 800 or 1500 barrels. After that date it was 400 or 800 barrel batches. A pretty sure sign of a fall in demand.

There was one definite change in brewing technique between this period and the last: the fermentation time was extended. In the late 1940's and early 1950's, it averaged 5 days but could be as few as 4. In this time period, it averaged around 7 days. I have no explanation for why this occurred. It's unlikely they carried out a major refit of the brewery in the austerity years just after the war.
The rate of attenuation is quite poor, averaging 69.7% for the samples in the table, down from the 71.5% for the set from 1945-1954. Which leaves almost every example below 3% ABV.

Now the recipe. And it is the recipe. Just four ingredients in the grist - mild ale malt, crystal malt, No. 3 invert and Hay's M - always in the same proportions. This shouldn't be a surprise. 1955 to 1975 was one of the most stable periods in British brewing. You could almost stay stagnation, at least in terms of top-fermenting beers. Average gravity barely changed at all 1951 to 1993. If you looked at the previous 40-odd years - a period stretching back to before WW I - you'd see average gravity varying between 1053 and 1033*.

The hopping is almost as boring as the grist, consisting mostly of Kent hops with only the odd Eastern European ones thrown in for variety. It always pleases me to see Saaz in British beers. No idea why.
That's it for today. Next time we'll cover the rest of the 1960's and the couple of years the brewery was open in the 1970's.

Ron- When trying to formulate a home brew recipe based on these tables, Should I treat the percentages of sugars and malts as by weight or as percent of extract?
