No one likes having too small a mash tun.
When you want to make a beer bigger than your mash tun allows, you have two options. You can mash with less water, which makes for a thicker than desired mash. This method might lead to prolonged mash times, incomplete starch conversion, and/or lower efficiency.
Another option is to perform a reiterated mash.
Reiterated mashing is done by splitting your big grain bill into two smaller grain bills as if you were making two beers.
You mash the first grain bill as normal with whatever water-to-grain ratio you normally use to mash.
You then run off and sparge as normal.
From there, you then start the second mash, but instead of using new mash water you use the wort you generated in the first mash as the brewing liquor.
In theory, you can then nearly double the starting gravity of the wort at the expense of running a second mash and a longer brew day.
We put this process to the test to overcome the Russian Imperial Stout mash issues John has had in the past. Check out this video to see how this homebrew experiment turned out.
BREW ON!
