It sat around, not being drunk (for want of a suitable occasion), until tonight, when I had a sudden eureka moment - it's a pocket rocket! Which is to say, a small, strong, readily consumed slug of booze, in a handy, easily concealed format.
Having figured it out, and knowing I'd never use it as intended, there was nothing else to do but drink it. Which I did. Here are my observations.
Nose: faintly reminiscent of oloroso sherry. Or tawny port. Or somewhere in between. Toffee, and a hint of struck match.
Palate: 17%? Really? Actually, there is a bit of heat in the finish, but the attack and mid palate are very light. Watery, if one could have sticky water. For sticky it is, in a pleasant toffee apple fashion.
Conclusion: It's very simple, but it's also rather direct and to the point, the point being a strong wee sweetie. I sort of wish I'd bought two...
