When I analysed the Let's Brew posts, I noticed that Porter was massively underrepresented. Odd given my obsession with Porter. And its key role in the history of British beer.
So, ever in search of some lose thread to tie the recipes together, we've decided to make February Porter Month. Except for last week's. My excuse is that the Tetley's Bitter recipe should have appeared a week earlier, when it was still January.
I was really pleased to get my hands on brewing records for regional Porters, like this one from Devenish. Courtesy of Boak and Bailey (http://boakandbailey.com/). (Thanks guys.) I've never quite got around to doing much with them. Time to put that right.
For those of you not au fait with English geography, the Devenish brewery was in the Southwest. Quite a way from London and pretty provincial. Which makes it perfect for comparing with metropolitan Porters. You can probably guess what's coming - some contextualisation tables.
Here's a comparison between Devenish Porter and those from a few London breweries:

Isn't that fascinating? Devenish Porter was weaker, but more heavily hopped that the London Porters. And pitched at an even higher temperature. And 64-65º F is already pretty hot.
I think I know why the London Porters were stronger: they brewed on a much larger scale in more efficient breweries. They could afford to brew a stronger beer and sell it at the same price. The London Porters in the table were had brew lengths of between 489 and 1261 barrels. The Devenish example was just 36.5 barrels.
Now let's look at the grists:

The difference is obvious: Devenish used a much higher proportion of brown malt. Their grist resembles London grists from the period 1805 to 1816: about two thirds pale malt to one third brown. With one difference: it contains a little black malt. Which was only invented in 1817. It looks like Devenish was lagging behind London brewers in terms of grist composition.
I think that's enough from me - over to Kristen . . . . . .

Kristen’s Version:
Notes: These babies are the cliff notes of logs. Tons of abbreviations. Tons of ‘random’ numbers. Such a cool chore to figure these bastards out. Its like a puzzle…a puzzle that gets you drunk! This is an opportunity to throw caution to the wind and make a recipe you wouldn’t normally.
Malt: Four malts. Two pale malts, the standard brown malt and a dash of roast malt. Pick your favs pale but I’d choose to go for some tasty mild malt. Mmmmm…mild malt. To more represent the brown malt of the era, I’d cut it 4 Brown: 1 fancy enzymatic amber or aromatic malt.
Hops: A vague ‘Knight’ hops so really feel free to use anything. My guess would be Goldings of some sort but really, be my guest.
Yeast: As with all these old recipes, nothing about yeast what so ever. So go nuts. Pick your favorite, I really like the London III for this baby.
Cask: Standard procedure:
1) let the beer ferment until finished and then give it another day or so. For me right around 5-7 days.
2) Rack the beer to your vessel of choice (firkin, polypin, cornie, whatever).
3) Add primings at ~3.5g/L
4) Add prepared isinglass at 1ml/L
5) ONLY add dry hops at 0.25g/l – 1g/L.
6) Bung it up and roll it around to mix. Condition at 55F or so for 4-5 days and its ready to go. Spile/vent. Tap. Settle. Serve at 55F.
