In my opinion, multi-step mashes increase efficiency only because you're more likely to stir the mash than with a single-step. This theory could be easily tested.


I suppose this theory is born from traditional mashes and not from recirculation mashes. We need some BM theories to work to.
To brew or not to brew, that would be a stupid question !

What has been reported is that when a test with iodine shows no unconverted starch and then the temperature is raised that starch is detected again. This should indicate that the higher temperature cracks some more starch storages that were still closed at the lower temperature.

Not my own tests, just repeating what I've read. It seems a valid explanation.

I'll do multi-step from now on and I don't expect any negatives because of it, any gains are welcome but not necessary.

I know that, both pre- and post-BM, I get better efficiency if I stir. It's possible that I get slightly better efficiency with the BM either way, but it's negligible. It's also hard to tell for sure, since I (almost) always did a mash-out pre-BM.

I would conclude from my own experience as well as what I've read from others, that doing a multi-step mash strictly for the sake of efficiency is not worth the effort and frustration with a typical homebrew setup.

I agree. Consistency over the years if your thermometer drifts a °C is my main reason for using mainly multi-step.
1 °C difference makes more difference in the naarow range of a single step than during a multi-step.
