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.

"Have you heard about poor Ron? He was killed when an unsecured 20-year column of pitch temperatures fell on him."

"Terrible. Still, it's the way he'd have wanted to go."

"I heard something different: the poor man went crazy trying to determine if EIP meant East India Porter or Export India Porter. He was last seen tearing his hair skipping along the canals mumbling 'time machine, I need a time machine'".
