Shut up about Barclay Perkins - Leftovers
Visit the Shut up about Barclay Perkins site
My new Scottish book is full of information. Too full. But even then, there's the odd bit I can't shoehorn in.
I spent the weekend looking at mashing details. I know that sounds a bit dull, but it was both English and Scottish mashing schemes. Which adds an extra piquancy. It meant putting together loads of fascinating tables.
But there wasn't room for all of them in full. I couple I just used extracts from. That's how stuffed full the book is. 70,000 words, at the moment. Though probably half of those "words" are numbers. That's how many tables there are.
The tables below I assembled for a larger table on mashing schemes in the 1930's. A fascinating topic. No, I'm not taking the piss. It is dead interesting. And through looking at mashing details more closely I've learned stuff. In particular, stuff about underlet mashing.
I've always though of underlet mashing - adding more hot water to the mash through the bottom of the tun a while after the initial infusion - as a particularly London practice. After looking in more detail, it seems that the practice was widespread in England. Though the process wasn't exactly the same everywhere.

Courage's underlet was relatively cool compared to Camden's:

Maybe I should start looking more at mashing. There's so much fun to be had.
