How to make a clean, neutral vodka at home
Vodka is the spirit with nowhere to hide, because the whole point of it is that it tastes of very little, so any fault in the wash or the run comes straight through in the glass. That makes it the best test there is of whether your process is actually clean, and it's also why a good one takes more care than people expect.
The licence, before the method
Making vodka from scratch means distilling, and distilling spirits at home in Australia needs an excise manufacturer licence from the ATO. It's a federal rule rather than a state one, so it's the same wherever you live. Owning or buying a still is completely lawful on its own. If you'd rather skip all of that, a bought neutral spirit with a vodka essence stirred through it is the no licence route, and honestly it's where most people start.
Start with a clean sugar wash
Traditional vodka is made from grain or potatoes, and at home almost everybody uses a sugar wash instead, because sugar ferments clean and leaves very little behind for the still to deal with. Use a yeast made for a spirit wash and hold it at the temperature on the packet, because a wash that runs hot throws off the harsh heavier alcohols that are exactly what you're trying to keep out of a vodka.
Use a reflux still, and go slowly
A reflux still runs the vapour back down over itself inside the column, which strips the flavour out and leaves you much closer to neutral. That's exactly the job a vodka needs done. Run it slowly and set aside the first part of the run, which carries methanol and the sharp solvent smells and is never drunk. Once the run starts to turn thin and oily you've reached the tails, and that's the point to stop collecting for a vodka.
Filter it with carbon
Even a careful cut carries a trace of something, and activated carbon is what polishes that out. Whether you dilute before or after you filter makes a real difference, and there's a separate post on the order to do it in, because it's the step people most often get backwards.
Water matters more than you'd think
A spirit straight off the still is far too strong to drink and gets diluted down to drinking strength, so a fair share of what ends up in the bottle is water. Use water that tastes of nothing, like distilled or filtered water, because chlorine or a strong mineral taste in your tap water will sit right in the middle of a vodka with nothing to cover it. Add it gradually and check the strength as you go.
Let it rest before you judge it
Give the finished vodka a few days in the bottle before you decide what you think, because a fresh spirit always tastes sharper than it will a week later. If it's still harsh after that, the fault is nearly always back in the wash temperature or the cuts, and more filtering won't fix either of them.

I'm of the view that a good vodka should be boring to taste, which is the one time you'll hear me call boring a compliment.
