Just a few tips from my own and others experience. Please add some more if you can.
1. To maximise your wash after derment. Some say rack to another container, I simply run the wash into the boiler after settling, when it gets to the tap level, slowly tilt the fermenter until the first bit of milky wash from the bottom is visible. Stop there. In an 800ml jar, take it to nearly full with the mucky stuff from the fermenter. Discard the rest. Funny thing will hapen over a couple of weeks. A clear fluid will separate over the dead yeast in the jar. This can be syphoned off and tipped into the next wash. It will have as much as 100ml of C2H5OH.
Also, take the temperature at the end of the distilling run to about 92 degrees, collecting these tails. Tip these into the next wash. There is still quite a bit of alcohol in this.
2. Put an old PC to use in your distillery or shed. Make an excel spreadsheet and fill it with useful stuff like
-notes about what is in each wash and your yield
-flow rates and temperature settings relevent to your still
-a calculator for diluting your end product
-temperature correction for your hydrometer
-calibration graph for your demijohn eg height of filling liquid vs. volume
-iventory list of your bottle colection
-wash temperaure calculator ( I made my own)
This puts all useful info to you in 1 spot and gives useful info for improving your product or fixing problems.
3. Carbon can be re-used, depending on purity of your distillate. (eg with a Pure Distilling still, I get 3 re-uses)
Boil the used carbon in a saucepan for 20 minutes with plenty of water. Sieve out the water. Then place on alluminium foil in a cold oven spread evenly, then set to 160 degrees. Leave for about 1/2 hour or until dry. Then place in jar for next time.
4. Use a medicine cup from the chemist as a measure for adding flavouring to your neutral.
5. Cotton wool stuffed into the neck of a funnel is a better (and cheaper) filter for carbon removal from neatral than coffee filters. Just be careful not to have it too tigfht or it will drip too slowly. Try to find funnels with wide necks.
6. Watch out for counterfeit stills. They are around. The easiest way to avoid is buying from authorised agents.
7. A wool blanket or old towel placed around the boiler when it it is first heating will speed it up on cold days.
8. Distilling conditioner to stop foaming is essential in smaller stills (5-25 lite) using turbo washes.
