Article: Use a medium temperature to slowly heat the wash over the course of 30 to 60 minutes until it reaches the desired temperature. Keep a close eye on the temperature gauge on the side or front of the still. Once the temperature reaches 120 to 140F (49 to 60C), turn on the condenser. The heat turns the alcohol into vapor, while leaving the water as a liquid. The alcohol vapor is condensed back into a liquid and collected in a water-cooled condenser. The "heads" refer to the first, toxic liquid that comes out of the still. The heads contain dangerous methanol that can seriously harm you if consumed. Be sure to dispose of the first 14 cup (59ml) of liquid from the dispenser. Never drink the heads! Contact your local government to determine if they are any specific disposal requirements pertaining to distillation waste. Continue collecting liquid from the condenser in small batches. The temperature of the still should be about 175 to 185F (79 to 85C) during collection of the "hearts" or the drinkable portion of liquid. You'll collect between 1 to 2 gallons (3.8 to 7.6l) of hearts, throwing out about 12 cup (120ml) of undrinkable heads and tails. When the temperature reaches about 205F (96C), throw out the last of the liquid. Dispose of at least the last 14 cup (59ml) of liquid, as these "tails" contain dangerous fusel oil. Never drink the tails! The tails don't contain methanol, so they can disposed of down the drain. Let everything cool down, then thoroughly clean the still.

What is a summary?
Heat the liquid slowly to 120 to 140F (49 to 60C). Turn on the condenser. Throw out the heads. Collect the hearts in small batches of 2 cups (470ml) each. Throw out the tails.
