Whitbread brewing records
As you can see, Whitbread were pretty conservative in terms of ingredients. Only three types of malt were used and at the end of the century a bit of invert sugar.
I was intrigued by how the brown malt percentage fell dranmatically sfter the introduction of black malt. Then rose again until about the middle of the century. The trend with black malt is much simpler - an uninterrupted rise as the century progressed.
That's it for now. I have to get back to my shift down the number mine. Lets hope there are no explosions.
