Stirring the mash

Post by guypettigrew » Fri May 08, 2020 1:20 pm

The latest Brewdog book recommends stirring the mash a couple of times during the 90 minutes, or however long you're leaving it for.

This is something I've never done, but wonder if it might be useful.

Any thoughts?

I use RIMS so couldn't say but I would have thought marginal and if the Tun is not heated in anyway you're just going to lose heat. If the mash is stirred until the temperature is evened out just leave it alone. I would be impressed if someone could tell a stirred mash from a left alone one.

Unlike Orlando I use a HERMS system (although the GF I use is effectively a RIMS system). So likewise, stirring offers no advantage so I leave it alone.

But I understand (from the dubious stuff I read) that the word "mash" comes from the old practice of continually stirring for the first 1/2 to 1 hour of the mash. As brewers don't do that anymore perhaps it says something?

I find using a GF that stirring 2 or 3 times improves efficiency.
