As I was researching the Union Jack recipe, I saw that FW uses a dual step mash to get fermentability up.  For those who do/have done this, what are your typical results?  

[Big Nake]

I have done a few Hochkurz mashes at 145x30 and 158x60 and noticed nothing. I think I would have to try to make the exact same beer two times... one with a single infusion and the other with the Hochkurz and see if I could tell. But the fact that I noticed nothing is not inspiring me to try it again. Also, I do not have a direct-fired mashtun so I have to raise the temp by adding boiling water so it's not a pretty picture.

I'm going to try 145x60, 158x30 and see what I get.  I won't have any comparison, but like most things I do in brewing...what the heck?

Maybe in your research you have seen this already but this guy got his UJ from 1.071 to 1.011 with a 145/60 155/10 mash and believe it or not WLP002

This is 5 years old but maybe worth a listen.

Here is the recipe summary from the episode above.

He also made Double Jack, again with 002 and went from 1.083 to 1.011 with it. Same mash schedule.

If I do a step mash, those are the temps I use.  But because I have yet to convince myself it makes a difference, I seldom do one.

145x60 the mash should already be converted before you even get to 158x30. Which is probably why nobody has noted a difference.

This is why I think it should go 145x30 and then 158x60. I should check my notes but I followed a process laid out by many people who had done it before and I always get 145x60 - 158x30 mixed up with 145x30 - 158x60... but I think it's the latter.

done this as well.  not convinced either way.

I do 148F for 20-50' and 158-162-F for 10-40'. I get higher fermentability than a beer mashed at 152F and more complete conversion than a beer mashed at 145F. That schedule gets me ~100% conversion in an hour and beers that finish at 1.008-1.010. Shortening the time at 148F allows me to increase the body, but still makes a relatively dry beer.

 

I do the step by infusion and it is extremely easy. I mash in with ~2/3 the water and use about 1/3 the water to do the step (edit: Since I do No-Sparge, this is more volume than the same would be for a Sprager). BeerTools Pro tells me what the infusion temperature needs to be and the result is always within a degree or so of my target. On the other hand, I wouldn't worry about hitting 158F on the nose, as anywhere just above that should work fine.

When i've mashed that low in the past it's taken more than an hour for conversion. That's at 147-149. I've never gone as low as 145.

Interesting. I always understood that lower mash temp could take longer for conversion. I've never had that issue mashing at 145-148* for my Saison's or Altbier's. I wish I could give you some accurate information on how many batches I've done and exact conversion times but cant. But there has been a lot! Its such a non issue for me I don't even take it into account. I guess you will just have to take my word for it. I'm sure mash thickness plays into this as well.

Oh, boy, do i have a treat for you guys.

Doing a double batch day today.  FW Union Jack and a dry stout.  I figured both could benefit from the dual rest mash so I tried it on both.  These being my 6th and 7th batches since starting up on this new system.  Definitely my two best efficiency mashes.  The UJ recipe came in around 73%, which is a hair below one of my other batches, but this is also a 15-20 point higher gravity recipe.  I had planned for 70%.  

 

The dry stout came in at 82% efficiency.  Much better than I've been seeing on the efficiency front.

 

It'll be interesting to see how well these beers dry out.

[HERMSman]

Last Sunday I brewed a Pliny the Elder clone. Fermenting now. Starting gravity is 1.080. I will report back if this mash step works again.

 

Cheers

Not surprised. I got a small bump in efficiency both times I did it. I should add that my mashes were 90 minutes prior to trying the step mash.

Isn't that a good deal higher OG than than pliny?  I recall my clone starting around 1.070.

1.070 is what RR states .. but a few more points would not hurt anything IMO.
