Shut up about Barclay Perkins - Barclay Perkins mashing schemes 1805 - 1929

Visit the Shut up about Barclay Perkins site

Ridiculous levels of detail. That's what this blog is all about. Providing a level of detail that no crazy person, let alone someone in their right mind, could ever require.

Mashing schemes. I haven't mentioned those for a while. I've just been harvesting numbers (it is autumn, after all) from a Barclay Perkins logs. Including the mashing details. It's all part of one of my many projects. One that, unlike some, might be completed this side of doomsday.

But I'm wandering. I promised you over a century of mashing schemes and I don't want to disappoint you. Here goes.

I suppose you expect some sort of comment from me now. Alright. If you insist.


The water to grain liquid increased from about 4 barrels (144 gallons) a quarter (336 pounds) in the early years of the 19th century to 5 barrels a quarter after 1860. Which was also when Barclay Perkins started sparging. They still performed multiple mashes, much in the manner of the 18th century, just with a sparge thrown in at the end.

After 1890 they started underletting. The process was mash, stand, underlet, stand, drain, mash, drain, sparge.

In the early 20th century, a second sparge stage was added. And after WW I the second mash was changed to an underlet.

That's all the analysis you're getting. If you need any more, you have to do it yourself. Maybe ytaking a long at the temperatures. I'm sure they've also a story to tell.https://blogger.googleusercontent.co...s.blogspot.com
