SAN RAE/SL, CA 94901 - 415/459-2520 THE GREAT FERMENTATIONS ALL-GRAIN, MASH/SPARGE SYSTEM 1) Equipment Your system includes, either a 5 or a 10 gallon insulated hot/cold beverage dispenser, equipped with a polypropylene False bottom, and brass rotary sparger. Outside of your normal equipment, you will need a racking tube that can handle 170 F. water. We have them in copper. Normal racking tubes will work, but may be permanently disfigured. Some people prefer to use a bottling bucket with a soigot for their sparge water. Either system works well. You will also need at least one, if not two, five or more gallon pots. One is needed for the sparge water, and one for the run-off pot, and a stove that can handle it. 2) Set-Up To prepare your system, fit the Sparge sperger in the hole in the lid, making sure not to wher damage the spinning section, as it is quite fragile. Fit the false bottom in the cooler with the rounded side facing up. Connect the hoss on the false bottom over the threads that lead to the spigot. A water-sight seal is not needed, just enough to keep grain from getting in and inhibiting the flow. You should position your system in a place where it will not need to be moved during the mashing and MAST sparging process, as it will upset the grain bed. and in turn may clog your soigot. It should be placed high enough off the ground so that you can collect the run off in your brew-pot. For the rotary sparger to function, it needs about 12 inches worth of water pressure above it, so position your sparge water accordingly. See illustration. Hot water is not always as easy to prime as cold water, or beer. I have tried to fill my racking tube with cold water, set It in my hot sparge water, and then connected il to my sparger a good 12 inches below the bottom of my sparge water por. Unfortunately, to no avail. The water refused to flow. I ended up starting the siphon with my mouth, getting up above the sparge pot. drawing the water up to within inches of my lips, and then bending the tube, and connecting it to my sparger a foot or more below the sparge-water pot. This worked without fail, although I must say that having near boiling water that close to my lips was a little unnerving. If you don't want the hassle, I suggest you make yourself a bucket with a spigot for your sparge water. 3) Mashing Add 1 to 2 quarts of water for every pound of grain ro be used. The water should be heated to 17-20 F. warmer than you wish to mash to compensate for heat loss from the grain and pre-heating the mash-tun. Add the water first. When you have added the water, slowly stir in the grain, taking care not to let any get under the false bottom. When all the grain has been stirred in, put on the top, and begin timing your mash. The temperature will stabilize within 10 min, and the pH should as well. If you wish to check these, wait 10-15 min. For info on mashing times, temperatures. and methods, ses Dave Line's Big Book of Brewing Miller's Complete Handbook, or our Al- Grain Handout. 4) Sparging To sparge, simply start your sparge water siphoning into the sparger for use a bucket fitted with a spigot). NEVER recirculate cloudy mash run-off through your spinning spargerl It will clog the fine holes and prevent i: from spinning properly. If you wish to recirculate cloudy run-off, you must by-pass the sparger, and sprinkle it in yourself. If you need to adjust your sparge water with gypsum, make sure it is thoroughly mixed in. As I mentioned before, it is sometimes more difficult to start hot water through a siphon. For this reason, some people use a bucket fitted with a spigot, which makes it much easier to control the flow as well. I siphon my sparge water, and use a hose clamp to control the flow. It's true a bucket is easier, but all I need are more brewing suppliesl I control the flow from the top, instead of the bottom, because turning the spigot on & off draws more grain into it, and if it clogs, the only way to free it is to unscrew the top of the spigot, and if that falls, suck on it to get it flowing again This shouldn't happen if you followed directions, but if it does, it is not the end of the world, it starts up fairly easily.
