Nicotine salts arrived as a specialist option: a formulation for low-power pod devices, sold alongside freebase liquids rather than instead of them. That framing has quietly stopped being accurate. Across most of the mainstream shelf, salts are now the default and freebase is the thing you have to go looking for.

The shift is usually discussed in terms of throat feel and absorption. We are more interested in what it did to flavour design, because that is where the change is most audible and least remarked upon.

What changes in the bottle

A salt formulation permits a higher nicotine concentration at a given level of harshness. That is the whole appeal, and it is a real one for anyone using a small device.

What follows is a design consequence. Freebase liquids at higher strengths had to be built around a certain amount of harshness — flavour houses worked with it, hid it, or leaned into it. Remove that constraint and the flavour has nowhere to hide. A salt liquid is a much more exposed piece of work: what you taste is more or less what was blended, without a nicotine bite covering the seams.

In our experience of the category, this cuts both ways. Good blends taste noticeably cleaner. Thin or unbalanced ones, which used to be partly masked, now sound exactly as thin as they are.

The sweetener consequence

There is a second-order effect worth naming. With less harshness to balance, the temptation is to push sweetener instead — because sweetness reads as fullness and is cheap. A good deal of the sucralose creep on this shelf is, we suspect, a downstream effect of the format change rather than an independent trend.

That is a flavour problem and a hardware problem at once, and we deal with it separately.

What has been lost

Higher-power devices remain freebase territory, and the ranges built for them have thinned considerably. For anyone using a larger device, the practical effect of the salt shift has been fewer options, not more — the shelf reorganised around the format that suits smaller hardware, because that is what most people bought.

Whether that is a loss depends entirely on what you use. It is a loss of variety either way.
