I usually take a while to finish my Latte. How long is it good for before it actually spoils?!

Probably 3-4 days.
Milk in the fridge lasts longer because it is kept cool, but with a latte the milk is essentially cooked by steam and will in turn stay fresh a little less long than regular milk.

Depends what temperature it's kept at. I've had partial leftover lattes that were in the car overnight in cool weather and they were fine the next morning. But a few hours in a hot car in summer, no good.

The same amount of time it takes for milk to spoil.
