The last couple of decades of the 19th century were happy times for brewers, as can be seen in the increase in Whitbread’s output, which more than trebled between 1880 and 1910.
What were the trends in grists in this period? Well, let’s take a look at what was happening at Whitbread again.
The obvious trend is a decline in the content of pale and brown malt and an increase in that of sugar and black malt. Then there’s the sudden appearance of quite a considerable quantity of amber malt in 1895. I wonder why that was?
Caution should be taken with the colour and bitterness numbers as they have been calculated with brewing software. Though I think that there was a clear decline in the bitterness, even allowing for possible errors in the calculations.
It’s not so clear with the colour. Especially as the 1900 colour was in large part dependent on a sugar I’m not 100% sure about. Perhaps getting a touch darker.

Maybe the malts were different in this era, but quantities of 20% amber and 13.75% brown malt would be frowned upon by modern brewers ?
