After the worts starts running clear (it will be dark and a little bit cloudy), you are ready to collect the wort and sparge the grainbed. The first few quarts are almost always cloudy with proteins and grain debris and this step filters out the undesired material from getting in your boiling pot. (See chapter 16.) A lot of homebrewers tend to skip the mashout step for most mashes with no consequences.Īfter the grain bed has settled and is ready to be lautered, the first few quarts of wort are drawn out through the drain of the lauter tun and poured back in on top of the grainbed. The mashout step can be done using external heat or by adding hot water according to the multi-rest infusion calculations. A mashout helps prevent this by making the sugars more fluid like the difference between warm and cold honey. This is when the grain bed plugs up and no liquid will flow through it. For a thicker mash, or a mash composed of more than 25% of wheat or oats, a mashout may be needed to prevent a Set Mash/Stuck Sparge. The grainbed will be loose enough to flow well. For most mashes with a ratio of 1.5-2 quarts of water per pound of grain, the mashout is not needed. This step stops all of the enzyme action (preserving your fermentable sugar profile) and makes the grainbed and wort more fluid. Mashout is the term for raising the temperature of the mash to 170☏ prior to lautering. These are: mashout, recirculation, and spargingīefore the sweet wort is drained from the mash and the grain is rinsed (sparged) of the residual sugars, many brewers perform a mashout. Lautering can be conducted several ways, but it usually consists of 3 steps. A lauter tun consists of a large vessel to hold the mash and a false bottom or manifold to allow the wort to drain out and leave the grain behind. Lautering is the method most brewers use to separate the sweet wort from the mash. In this chapter, we are going to discuss how we separate the malt sugars from the grain. We learned about the several basic methods of conducting a mash and producing the wort. In the last chapter, we moved from the chemical aspects of the mash to the physical. Okay, let's see where we are: we have discussed the different types of grain and how they can be used, we have talked about the mash enzymes and how they are affected by temperature and pH, and we have learned how the brewing water and grainbill combine to determine the mash pH and how we can manipulate it.
