Firstone Walker Union Jack Clone

Back to the brewing network's "Can You Brew It". I love this show. I managed to get some fresh Union Jack when I was in San Francisco back in October. I remember thinking it was pretty awesome, though I can't remember anything specific about now. I just decided it's time I did a west coast IPA style beer and this recipe looks the goods.

I'm still working on the new setup. Efficiency (63%) was quite poor once again. I think this is coming from two places:

1. My blichman autosparge is returning wort via a silicon hose, which is causing a whirlpooling effect. This is causing an obvious channelling problem. I need to rethink how to return wort and sparge. 
2. I'm collecting wort far too quickly in the sparging process.

I've removed the stainless braid from my kettle output. As I mentioned in the last post it was getting hopelessly clogged with a medium hop bill, it wouldn't have any chance with this hop bill. Also it was interfering with whirlpooling by effectively drawing wort from the whole of the outside rim. Now I've just got a simple pickup tube with no filter of any kind. It worked quite well, with a decent trub cone developing through simple whirlpooling and I was able to drain all but about 2.5L from the kettle without getting a lot of hop debris in the chiller.

So even though my mash efficiency was the same as the last brew, my brewhouse efficiency was way up. I'm half way there I guess. I ended up with an OG of 1.063, 7 points off the CYBI recipe, but only 3 off the recipe in Mitch Steele's IPA book, so I'm hopeful I'll still end up with something pretty good.

I'm a little worried about my starter. It was a 2.5L stirred starter of WLP007. The starter beer had a very slight sour edge, and I was sorely tempted to throw the whole thing out. Then I found this post on homebrewtalk.com, and decided it was probably ok. Now I'm not so sure. I guess we'll find out.

Despite the slight disappointment with mash efficiency, and being another night time brew, the whole thing went really smoothly. I think this was due in large part to creating a job list before hand. I hadn't done this before, but it really helped keep any panic at bay. Here it is:

So it's back to brewing classic styles for the first beer through my new mash tun. I've dispensed with the bag for now and I'm close to finishing the 3 vessel system I've been building for the last few months.

Progress

The recipe is one I've done several times before, though I've played with the hops a little. The brewday itself was besieged with issues from the off:

1. I connected my heat exchanger backwards during the initial mash, and the wort ended up hitting 69C through the HEX for a short time before I spotted the error and dropped it back to 66C.
2. I ran my sparge water through the HEX to ensure it was at the correct temperature, but once again I connected it backwards and may possibly have heated some sparge water way above an acceptable temperature, also the water in the HEX boiled for a moment which is not good.
3. I didn't heat enough sparge water and ended up topping up the kettle with around 3.5L of water to hit the pre-boil volume. 
4. My hop filter using a stainless braid got completely clogged with pellet hops and I left around 5L of wort in the kettle at the end of the brewday.
5. Efficiency was poor,  around 63%, a combination of mill gap and running out of sparge water.
6. The final insult - I messed up setting the temperature on the fermenting fridge and 12 hours after pitching the yeast it was sitting at 12.5C.

I'm still hopeful it's not a complete disaster, but I'll be lucky to pull some decent beer from this brewday, and in any event I'll be very short on volume.

One nice result from the whole experience was the clarity of the wort at the end. It's unlike anything I've seen before from any other brew setup I've used. Hopefully it translates into clearer beer, though I'm not so sure about that.

 Anyhow, that's the first and hopefully the most painful brew on the new system. You can plan these systems out all you like but you don't really get an idea how it all works together until you fire it up. I now know where I need to concentrate my efforts to get this running smoothly. I need to:

1. Sort out draining of the kettle to the plate chiller. Some ideas below
2. I need to heat more sparge water than seems necessary, better to have too much rather than too little. I was still getting 1.024 from the last runnings out of the mash tun so missed out on a lot of sugar here.
3. I need to tune the mill gap a little. I had no issues with sparging so there seems to be some room for adjustment.
4. I need rules about HEX connections. It matters which way it's connected.
5. I need to mount the controller properly. At the moment it's just sitting on the edge of the stand.

For the kettle draining, I'm going to have to abandon the sparge braid as a hop filter. It just isn't up to the job and it's also having a dramatic effect on my ability to create a whirlpool in the kettle. Because I'm effectively draining the kettle from the whole of the outer rim, the whirlpool has no chance to gain any momentum.

My plan is to replace the braid with a simple side facing pickup tube and simply depend on an effective whirlpool stage to concentrate hop debris away from the pickup tube. I'll need to throttle back the outlet to avoid upsetting the resulting cone of hop debris. Also this means I can't really use the boiling wort towards the end of the boil to sanitise my chiller, so the chiller will have to be sanitised separately. Maybe I'll figure out a clever way to do this, but I can't think of one right now.

Here's the recipe:

5.1Kg Barrett Burston Ale Malt
0.34Kg Weyermann Munich I
0.34Kg Joe White Wheat
0.23Kg Breiss Victory

Water treatment: 2.5tsp CaSO4, 1tsp CaCl2, 1tsp MgSO4, 0.25tsp lactic acid

20g Cascade 7.9% @ 10
20g Centennial 9% @10
20g Cascade 7.9% @ 0
20g Centennial 9% @0

Pitched 200ml slurry of WLP001. Fridge set to 19C (or so I thought, dipped to 12.5C but quickly corrected back to 19)
