AG#25 – Union Square Steam Beer


I’ve wanted to do a steam beer for a long time, even going as far as buying the WLP810 yeast a year ago. Unfortunately, I couldn’t fit it into my schedule and the yeast languished at the bottom of my fridge for a year before being thrown out.

08/12/2014 – Made a 1.2 litre starter with a vial of WLP810 California Lager yeast and 120g of light dry malt extract. Transferred to growler and shook to aerate.

15/12/2014 – Mashed at 66C, but couldn’t seem to get a consistent temperature reading, even at the end of the mash. Put the late addition leaf hops in bags, used perhaps a little more Whirlfloc than usual, started the chiller as soon as boil finished and subsequently got a great cold break and runoff from the boiler. Had a lower post boil gravity than intended but I did start out with slightly less in the boiler this time. Got an OG of 1.055 which is spot on. Also blocked the Insinkerator with the leaf hops but that’s another story. Just realised that I misread the recipe and used too much hops so ended up with a few more IBUs than intended. The hops weren’t particularly fresh though, so it’ll probably be fine.

16/12/2014 – First time using a lager yeast strain so a bit nervous about this one taking off, but it seems to be doing fine. No action from the airlock as yet. Will need to take a temperature reading this evening, as there’s a chance that I’m actually fermenting this too cold.

11/01/2015 – Bottled with 120g of corn sugar (17 litres at 2.6 vol). Got 6 x 750ml and 23 x 500ml bottles. Tastes fantastic, the biscuit malt and pale chocolate malt giving a wonderful toasty flavour.

01/02/2015 – I was very disappointed with this when I opened. Instantly I knew it was under-carbonated. Not hugely so, but the head formation is not good enough and not quite enough carbonation for the style. I think another 10-20g would have been perfect. On the upside, beautiful flavour. Nice bit of caramel, great “lager” flavour, dry and toasty on the finish. I was concerned there would be too much roast flavours from the pale chocolate malt, but it doesn’t come through. Instead it gives the beer a beautiful dark amber colour. One other disappointing thing is the hazy appearance, which I wouldn’t have expected in a beer that isn’t particularly well hopped.
