Pour in mash, but take care to keep the sediments that have settled in the
bottom of the container from going into the still since they can cause
off-flavors. Additionally, leave approximately 4" of space at the top of the
still to prevent boil over into the top section or worse, the swan neck and
condenser.
Place and seal the onion top. The sealing can be done using a thick
water/flour mix and pushing it in and around the seam where the top and
bottom meet. Another option is wrapping the bottom of the onion head
with plumber's Teflon tape before setting it in the bottom part of the still.
Attach condenser
Keep the condenser cool. This is done by filling the condenser body with
water and continually adding ice (frozen water bottles work great too) or
using a continuous stream of cool water from a kitchen faucet or water
hose (while the condenser is equipped with in and out nozzles for total
control, this could be as simple as plugging the bottom and letting a water
hose run in the top).
Set a container at the outlet of the still to catch the moonshine. Keep in
mind that while some plastics are fine to use, most are not able to safely
handle high concentration alcohol. Play it safe and use glass, Mason jars
are excellent for this.
The Run
Start applying heat. Use high heat until you can hear the mash boiling.
You can also carefully touch the pipe that connects the onion-top to the
condenser, when the still is up to operating temperature this wilI go from
cold, to warm, to hot very quickly. Once you reach this point, cut the heat
to half.
Regulating heat: once liquid starts to come out of the condenser, you want
to turn down the heat so that it is not a constant stream. Drips are fine, as
are breaking or intermittent streams, but a constant stream means the
temperature is too high. This may seem complex at first, so an alternative
way of monitoring the still temperature is a handheld temperature scanner.
They are available from local hardware stores for $20-25. If you use this
