Stop in for a drink.

I mentioned before what the science was behind letting spirits breathe to change the flavor. But I didn’t mention what warming it does to further that.

All of the volatile components have different boiling points and therefore different vapor pressure. Vapor pressure determines the rate of evaporation at a given temperature.

Try warming up your spirit of choice by a few degrees and note how it changes. Kinda like brandy in a snifter which is designed to be warmed by the hand to release the low boiling volatiles and get the best flavor.

Put a spirit in a metal cup and gently warm over a heat source like a campfire, candle or even a lighter. Sip at various intervals of time over the heat.

Note the changes as you go....you might be surprised at what you find by the end of the experiment.
If I can still stand at the end of the experiment I might be able to tell the difference.
