Whitbread PA grists 1939 - 1945

Whitbread’s grists were a little simpler than those of Barclay Perkins. In terms of malts, it was very similar, with base pale or PA malt plus crystal malt. Unlike Barclay Perkins, Whitbread had already included crystal malt in the grist before the outbreak of war. Unusually, they had started employing crystal malt in PA in 1928. That’s much earlier than most breweries.

Most of the time there was only one sugar, No. 1 invert. The exception was in 1940, when they briefly used something called DM in addition. No idea what it was, other than that it was a proprietary sugar. At the start of the was sugar made up 15% of the grist, but after a year that fell to 9-11%. Presumably this was dictated by the amount of sugar they were allocated by the government.

Before the war, Whitbread employed no unmalted adjuncts, just malt and sugar. That changed during the war due to government demands. The type of adjunct used was also determined by the government. Mostly it was in the form of flaked barley, except in 1943 when there had been a bumper oats crop and the government directed some of the surplus for brewing. Not being great fans of adjuncts, Whitbread dropped flaked barley in autumn 1946, probably as soon as it was able to.

Like Barclay Perkins, Whitbread employed English hops, mostly from Kent, but also ones from Worcester and Sussex. They were usually from two or three different years. This wasn’t a result of the war but something they had practiced during the interwar years. As those from older harvests had been kept in a cold store, they would have retained most of their alpha acid.

Just before the end of the war some Oregon hops pop up. Presumably the shipping situation had improved sufficiently for imports of hops to resume.

There was little variation in the colour of PA. It was usually 25-26, which is about what you would expect for a beer of this type.

DM = Dxxxx maize? Maize would be pretty typical of a southern brewery at that time, no? Or = dry malt? but would be weird to use it in quantity.

Using crystal in 1928 suggests it's a bit more than just a response to the thinning out during the war, although obviously 1928 wasn't exactly a happy time either. I always wondered if it was in part a response to changing barley varieties, an attempt to hark back to the flavour of beer made with Chevallier when less flavoursome varieties of barley were introduced.

Another thought is that it roughly coincides with the Mackeson acquisition, were Mackeson using crystal before they were bought?

qq,

DM is in the sugar column. It has to be a type of sugar.

Changing barley varieties, or malting techniques, could have been the reason for adding crystal malt. Or not wanting to use caramel to colour. There are lots of possible reasons. Customers wanting a sweeter beer is another one.

Most likely it was the result of a combination of factors. It's one where, for once, government fiddling doesn't seem to have played a part.

Hi Ron ,
Could it be something as simple as Duttson`s Mauritius or similar ??
Cheers
