Spiced rum or smooth rum, which one to make at home

The first sip out of a new batch tells you fairly quickly which camp you're in, because a spiced rum arrives loud and a clean unspiced one arrives quiet, and both of those are perfectly good answers. The question worth asking before you start is which one you'll actually drink, since a bottle of something clever that sits on the shelf isn't much of a result.

The licence bit, said plainly

Owning a still is lawful and selling them is lawful, and running one to actually distil spirits at home without an excise manufacturer licence from the ATO isn't, so if you're going down that road the licence is the part to sort out first. Adding an essence to a base spirit you bought is a completely different activity and it needs no licence at all. The whole thing is written up in making your own spirits at home without breaking the law.

What separates them

Spiced rum. Nutmeg, clove, vanilla and cinnamon over a rum base. It mixes hard and it stands up to cola or ginger beer without vanishing, so it's the one people reach for when there are a few of you around a fire.
Smooth unspiced rum. Clean, with oak character doing most of the work instead of added spice. It goes neat or over one big cube, and it shows up every flaw in your base spirit, which is either a problem or a useful test depending on your mood.

Which is the easier first batch

Spiced, comfortably. A spice profile is forgiving because it covers a multitude of small sins in the base, and a smooth rum has nowhere to hide, so if your neutral spirit carries any harshness the unspiced version will tell you about it in the first mouthful. Start spiced and get a feel for how much essence you actually like, then move to the clean version once your base is reliably good.

Getting the spice level right

The common mistake is going by the bottle rather than by taste. Add most of the essence, stir it through, then taste it cold rather than at room temperature, because chilling flattens the aromatics and a rum that tasted balanced warm can taste thin over ice. Hold a bit back and add it after a day if it needs it. Taking spice out isn't a thing you can do.

Oak, if you're going smooth

An oak flavouring is what gives an unspiced rum the roundness it would otherwise get from a barrel, and it works in drops rather than splashes. Add a small amount, leave it a couple of days and taste it again, because oak keeps developing after you stop stirring and it's very easy to overshoot. Keep notes on how much went into which bottle, since that's the only way any of it becomes repeatable.

Drinks for each

For the spiced one, cola with a wedge of lime, or ginger beer with a bit of mint, and honestly it's also good on its own on a cold night. For the smooth one, neat in a small glass, or one large cube and nothing else. A smooth rum in a mixer is a waste of the work you put into it.
