Whitbread brewing records held at the London Metropolitan Archives

As you can see, the gravities are very similar, starting in the low 1030's before the war and dropping to 1028 after 1942. Whitbread's Mild was tiny bit more heavily hopped, but scarcely enough to be significant.

The grists are quite different. Lees was much simpler: just pale malt, a touch of black malt, glucose and invert sugar. Until flaked barley and flaked oats appear in the later war years. Whitberad used more different types of malt, in particular crystal and MA malt. But the biggest differnce is the colour. Whitbread Mild was around 90 EBC, Lees just 29. So despite being broadly similar in terms of strength, thse two beers must have tasted and looked pretty different.https://blogger.googleusercontent.com/tracker/5445569787371915337-7728907393694758639?l=barclayperkins.blogspot.com
