Default AG#4 Fuller's London Porter Clone

Looking at potentially doing my fourth AG brewday next Sunday and thought I'd run the recipe by the forum. I won't post the amounts up as they're straight from Graham Wheeler's book and then adjusted for my equipment using the great man's Beer Engine.

Maris Otter
Brown Malt
Crystal Malt
Chocolate Malt

Fuggles 90 mins
Fuggles 10 mins

I'm aiming for 23 litres at an OG of 1053, but have been short on every brew so far. Last time only by two litres, so I'll use the same calculations this time and see whether I fall short by the same amount and if needed add boiled water at the end.

The recipe doesn't mention any Irish moss additions, I presume this is because it's a dark beer? Is it worth putting in half a tablet anyway?

Also, I have a SO4 yeast set aside for this, but if I was to grab a bottle of Fuller's Bengal Lancer tomorrow would I have time to get this up to a decent size if I harvest it with some dry malt extract over the next few days?

Irish moss doesn't do any harm.

You'd need at least 24hrs for each propagation step. I don't know how many steps are required when harvesting yeast from bottles, but i guess it's more than 3.

I would have thought it will take you about 5 days to get a pitchable volume.

+1 for Irish moss if you don't you wont get a cold break.

Ah damn it, I think I only have around 500g DME so probably not enough for different stages. I've never propagated yeast before and sort of imagined I'd pitch it with the solution, leave several days, then pour off the wort and pitch the remaining yeast. I didn't realise there were lots of different stages.

500g DME should be enough, you need 1.040 wort so this amount will be sufficient for 5 litres.

I see, so do I add the dregs of the bottle to a 5 litre DJ with 500g DME dissolved in, then after around 5 days drain it off and add to the brew come brew day?

Great stuff, cheers. I've got 2 litres of water mixed with 200g DME boiled for 10 minutes and now cooling to room temperature. The Bengal Lancer is in the fridge to settle the yeast, and I'll be enjoying that later and pitching into the cooled wort. Fingers crossed it'll be good by Sunday, if not I have a S04 to fall back on.

Not much action from the pitched yeast this morning...

It will take a while as the yeast is usually very dormant.
