Let's Brew Wednesday - 1837 Reid P

Reid was one of the largest Porter breweries in the 19th century. Never the largest, but sometimes second behind Truman or Barclay Perkins. In the early 19th century, they were briefly the largest in 1907 and 1808, but their production remained fairly stable while others expanded.

Here’s how the London Porter brewers ranked in the 1830’s:

This is a pretty typical Porter of the time. With the familiar combination of pale, brown and black malts. All pretty locally sourced. The pale was from Sussex, the brown from Hertfordshire. The hops were all pretty local, too: Mid Kents from the 1835 and 1836 crop.

As a third of the hops were over two years old, I’ve knocked the total hops down from 4.62 ozs. to 3.75 ozs. It still leaves a calculated 44 IBUs.

The mashing scheme was quite complicated: three mashes and no sparge. There was a fourth mash for a return wort.

action water (barrels) water temp. tap temp. time
mash 207 162º F 145º F 90
mash 150 180º F 164º F 50
mash 179 151º F 153º F 40

This was a beer that wasn’t vatted and would have been drunk young. Or perhaps blended with Keeping porter at racking time. As with all Porter and Stout, the fermentation was quite hot, hitting a maximum temperature of 78.5º F.

When they did these multiple mashes were the first runnings pulled off and then the next addition(s) of water added... or were the subsequent additions just added to the whole mash?

Ron Pattinson said...


obviously they ran off the wort between mashes.

So, I'm going to go ahead and ask: Is the boil length supposed to be 75 or 90 minutes long?

Ron Pattinson said...

Pisshead Philistine,

75 minutes.

Is there any connection with Reid's of London and reid's (also Read's) of Dublin There were Reads brewing in Dublin 1750-1890. They were also involved in Malting. They were among the early stout brewers in Dublin and breweries at several sites over the years.

Ron Pattinson said...


this is Reid of London. Of the Griffin Brewery, Clerkenwell. Don't think there's any connection with the Dublin firm.
