AG #18 - Bunker Steam

[bunkerbrewer]

No-one really knows how Anchor Steam got it's name, but I brew indoors so there is a fair amount of steam!

I brewed a California Common a while ago out of curiosity, but it was an immediate favourite with SWMBO and me, so I thought I'd better get another one on. I'm using the "Sunday lie-in mash" method. Set up the boiler last night and did my water treatment, put the mash on at 7:00 this morning and went back to bed :)

This style is all about the yeast - San Francisco Lager yeast - and you do need temp control to do it justice.

Single step Infusion at 66°C for 90 Minutes.
Fermented at 14°C with WLP810 - San Francisco Lager

Ferment the first 7 days at 14C, then raise to 18-20C gradually over the next 7 days with the last 3 days between 18-20C, then crash cool to drop the yeast out.

Mashing out:

BIAB gives quite dry spent grains, so they're a bit easier to dispose of. This is my high-tech storage box + wire rack bag draining method:

Hops and yeast (reclaimed generation 2 WLP810 starter stepped up over the last week):

looks like a smashing brew :thumb:

you might be interested in this Brewery http://www.lindenbeer.com/ they sent me the recipe for the Urban People's Common Lager and have brewed it a few times. I like using WLP810 as I have a cellar that is just right for fermenting with this yeast, and have used it in traditional German lagers with good results.

Ooh, that is interesting, thanks! Do you think you can share their recipe? I like the idea of using WLP810 for a lager too. :thumb:

this is what I got from Adam at the brewery

70% Pale
10% Vienna
10% Light Munich (I use Weyermann Munich I)
10% Carahell
Northern Brewer at 15min and 45min of 60min boil
OG 1054; FG 1012; IBU 39
Ferment at 55-57F

So when I brew it I do a 90min boil and add 30g of NB (AA 9.9%) at 45min and 30g at 15min and mash for 90mins at 67C. It's a very nice beer with a good bitterness and sweetness. I find it is at it's best after 6 weeks conditioning.

I've also done the recipe with a 50/50 mix of NB and Chinook, which made for an interesting beer

Brilliant, thanks very much!
