First, RDP (a Porter of some sort) from 1899:
This looks pretty straightforward to me. No sign of dropping. Then fined and racked at the end.
Next X Ale from 1906:
Slates 6 m 6 4.8 @ 62 1/2
Wood Skim 6 m 8 4.6 @ 63
Cop. do 6 m 10 4.6 @ 63 1/2
6 m 6 = 6th 6 AM [date and time]
4.8, 4.6 = gravity in pounds per barrel [attenuation of the wort]
@ 62 1/2 = 62.5º F [temperature of wort]
I'd be interested in what you make of that. I won't influence you with my opinion.
And finally XLK from 1919:
Here you can see the use of the attemperator. "Liquor on" means running cooled water through the attemperator pipes. The bit on the bottom right is informative. It gives the numbers of the fermenting vessels followed by SB's, SK Wood, SK Copper. What do you reckon that means?
Here's another I've just found which clarifies some points:
If you look in the bottom right hand corner you can see that two different actions were carried out on Trade XLK. FV numbers 6 and 22 were cleansed, FV 19 skimmed. Which implies that the SB FV's weren't fitted with skimming parachutes.
I wonder if there are any plans of the brewery in the archive?
