Hop additions. What a fascinating subject. Just a shame that they are so poorly documented in the brewing records I've looked at. With one exception: Barclay Perkins.
Their logs from the 1920's often contain detailed information about the hopping. It's a great insight into this aspect of British brewing. So much so, that I felt obliged to share some of the details with you.

I'm in a bit of a rush, so I'll leave you to ponder that.
OK, a couple of quick remarks.
@inch: I'm pretty sure that means when the copper has been filled with wort.
makeup: I think this is at the start of filling the copper. Though I could be wrong.
I was a bit surprised at the lack of late additions in the Pale Ales. And that there were mostly only two hop additions (the export PA and bottled IPA had three additions). Especially as the standard Mild, X, had three additions.
The Stouts are even more surprising. TT (Porter) and BS (Best Stout - the standard Stout) had all the additions right at the start. The stronger Stouts had four additions, at inch, after 1 hour, 1.5 hours. and 2 hours in a 2.5 hour boil. IBS Ex (Russian Stout) had five additions, at inch, after 1 hour, 1.5 hours. 2 hours and 2.25 hours in a 2.5 hour boil. The last is the latest of any of the hop additions.
In general, it seems the stronger the beer, the more hop additions. Isn't that fascinating?https://blogger.googleusercontent.com/tracker/5445569787371915337-4787474584029054747?l=barclayperkins.blogspot.com

I'm in a bit of a rush, so I'll leave you to ponder that.
OK, a couple of quick remarks.
@inch: I'm pretty sure that means when the copper has been filled with wort.
makeup: I think this is at the start of filling the copper. Though I could be wrong.
I was a bit surprised at the lack of late additions in the Pale Ales. And that there were mostly only two hop additions (the export PA and bottled IPA had three additions). Especially as the standard Mild, X, had three additions.
The Stouts are even more surprising. TT (Porter) and BS (Best Stout - the standard Stout) had all the additions right at the start. The stronger Stouts had four additions, at inch, after 1 hour, 1.5 hours. and 2 hours in a 2.5 hour boil. IBS Ex (Russian Stout) had five additions, at inch, after 1 hour, 1.5 hours. 2 hours and 2.25 hours in a 2.5 hour boil. The last is the latest of any of the hop additions.
In general, it seems the stronger the beer, the more hop additions. Isn't that fascinating?https://blogger.googleusercontent.com/tracker/5445569787371915337-4787474584029054747?l=barclayperkins.blogspot.com
