No new brewday reports must signal that it’s time to start planning the next brew. We also need to plan keg and bottle capacity with the Christmas break in mind. It’s been a hectic year away from the Boxshed, and we’re looking forward to a nice chunk of downtime over the Christmas holiday. We’re plotting to get on a bit of a cooking and pickling buzz too, so we need a few beers on tap to offer anyone popping over for some seasonal cheer.

We’ll reserve our keg of Timmy’s Original for December, and perhaps some Dark Garden too, but will be tapping the Brown Corduroys this weekend and drinking it over forthcoming Bonfire nights. Ideally we’ll brew twice more over the next three weeks to create a Boxshed Dry Irish Stout ’09 (yummy with port!), plus an-all new Premium Pale Ale, maybe with a twist.

This means paying bills for old supplies and restocking with Marris Otter and one or two other speciality malts, ordering up some liquid yeast and preparing a starter for the stout, fixing two poppet valves in two faulty kegs, getting hold of some new sanitisers, cleaning a lot of bottles and other vessels, devising a new recipe for a fun pale, and seeing the Timmy’s Original safely into kegs.

All we’ve managed to do this weekend however is move the Timmy’s Original from primary fermenters to clean secondaries. It reached 1.012 with no problems, looks clear, smells great and just needs to be cared for this week prior to racking. Dry-hopping is also an (unlikely) option, but we’ll update if we go take that route.

In the meantime, for no good reason, here are a couple of photos of the Timmy’s transfer, leaving all that once-frenzied trub nicely behind.

PS – There’s an Autumn beer and cider festival going down every day this week at The White Horse, Edwardstone, Suffolk, culminating in a blue grass shindig on Hallloween itself. If you’re in the area, you really ought to pop over there for a pint or six. Here’s the brew list.

After a week or so in primary, this impressive smelling stout was ready to be moved into secondary. I also wanted to take this opportunity to harvest that valuable liquid yeast, which by now had grown and taken over the bottom of the FV bucket, and which threatened to turn into The Magic Porridge Pot. It will stay in secondary for at least another week, then I’ll post a kegging/bottling update and sort out another brewday, finally…

This turned out to be a very relaxed brewday with my new mashtun. Because I hadn’t sorted out the sparge manifold to my satisfaction just yet, I reverted to batch sparging for this one – there’s plenty of headroom in the thermo box after all!

The plan was to make a dry Irish stout, not a million miles away from Guinness in terms of overall bitterness, but with the added fun of using my own grown WGV hops in the copper. I added a small amount of wheat malt for head and feel. I also ordered liquid yeast especially for this brew, although I probably ought to have given it more time to multiply ahead of brewday – ah well, it’ll be fine I’m sure.

Anyway, here’s the full recipe:


Boxshed Seasonal Stout
Date: 08/11/2008
Style: Dry Stout (Irish)
Batch Size: 23.00 L
Boil Volume: 32.00 L

0.8 kg Flaked Barley (3.3 EBC) 14.5%
0.75Kg Roasted Barley (591 EBC) 13.6%
0.2Kg Wheat Malt (3.9 EBC) 3.6%
65.00 gm Whitbread Golding Variety (WGV) [5% est.] (60 min) Hops 36.7 IBU

Protofloc Tablet (15 min)
1 Pkgs Irish Ale yeast (White Labs WLP004)

Batch Sparge
Mash Grain Weight: 5.25kg Mash PH: 5.4 PH
Grain Temperature: 13.0 C
Mash In Add 13L of water at 69.3C (63C) 90 min
Step Add 11L of water at 67.7 (65C) 10 min
Step Add 11L of water at 80C (75C) 10 min

Beer Profile
Estimated Original Gravity: 1.050 SG

Estimated Alcohol by Volume: 4.8%


Below are some photos and descriptions of the day. I mashed-in at around 11am in the end, and pitched around 4pm, managing to fit the process around various chores. The new mashtun was superb and made me want to replace my boiler with something equally cool looking and move my boiler to be the HLT. One day, maybe. In the end I got 23L exactly in the fermenter with no need to add any further liquor, but I missed the 1.050 OG and got 1.048 istead. I’m putting this down to not compensating for the switch to batch sparging, which seems reasonable.
