Partial Mash Methods (Brewpot Mashing with Colander Lautering)


A colander sits above a 5-gallon (~20-L) brewpot. The grains were mashed in the small pot while sparge water heated in the medium pot.

As I mentioned in my previous article, partial mashing provides many benefits, especially for extract brewers. Procedurally, it is very similar to steeping specialty grains — you just need to hold your temperatures and liquid volumes within a certain range. There are a wide variety of ways that homebrewers perform partial mashes. Today I’ll explain one of the most common ways for stovetop brewers to do a partial mash. All you need is a steeping bag to hold the crushed grains and a colander large enough to fit on top of your brewpot. Standard spaghetti-draining-sized colanders will fit over many pots around 5 gallons (~20 L) in volume This method works best for partial mashes with 2–4 lbs. (~1–2 kg) of grain. I’ll explain tomorrow another method for performing larger partial mashes without switching to a full-sized, homebrew mash/lauter tun.
