Not sure how long I'll be arsed to do this. If you want me continue you'd best be really enthusiastic. Even better, donate some money. That's the best way to incentivise me to continue.
We'll start with a really easy bit. You should be able to work out the header without my help.
Working from left to right:
The date: Wednesday 7th October 1891
The weather: A (atmosphere) 49º (F) Fine
The beer: BS (Brown Stout) 26 (brew number of Brown Stout, i,e this is the 26th brew of it this brewing year)
The gyle number: No. 122
That was pretty simple. Next it's the turn of the grist.
First are the malts, measured in quarters of 336 lbs and bushels of 42 lbs.. There are five of them:
1 quarter 2.5 bushels C (crystal malt)
3 quarter 2 bushels HB (Hertfordshire brown malt)
7.5 bushels of HA (Hertfordshire amber malt)
2 quarters 3 bushels of roasted malt
22 bushels and one bushel of W (white malt)
Total 28 quarters 4 bushels and 30 quarters.
Why are there two totals? Not totally sure, but I think the one on the left is weight quarters, i.e. 336 lbs, and the one on the right is volume quarters. Because a quarter was originally a volume measure. There were big differences in the weight of a quarter. In this brew, they varied between 268 lbs and 320 lbs, with the roasted malts being the lightest.
Finally there's the sugar:
Sacc 9.5 quarters
Note that a sugar quarter was 224 lbs.
Now the hops.
Four types of hops:
EKs /91 (East Kent, 1891 harvest) 1.24 (1 quarter of 28 lbs, 24 lbs: total 52 lbs)
EKs /91 (East Kent, 1890 harvest) 1.24 (1 cwt, 2 quarters, 14 lbs: =112+56+14, total 182 lbs)
EKs /91 (East Kent, 1889 harvest) 1.24 (1 quarter of 28 lbs, 24 lbs: total 52 lbs)
EKs /91 (East Kent, 1886 harvest) 1.24 (1 quarter of 28 lbs, 24 lbs: total 52 lbs)
Total 3.0.2 (3 cwt 0 quarters 2 lbs) 338 lbs = 3.0 b (3 lbs per barrel)
Peckham, Jenner, Harnett, Tompsett (names of the growers)
The growers are in the same order as the hops. That is, EKs /91 are from Peckham.
That wasn't too hard, was it?
