You are quite right - the flavouring does indeed change the shelf life in a certain way. It is necessary to look at this from two perspectives.

## **Shelf Life by Safe Consumption:**

The flavouring compounds used to flavour coffees last longer without degrading. This means that they **ARE NOT** the limiting factor when it comes to the shelf life of a coffee. **Therefore, shelf life is not changed by flavouring the coffee as these compounds degrade (or go bad) after the coffee itself.**

## **Shelf Life by Taste:**

Because the coffee has been treated with flavouring compounds, it will hide certain aspects of degradation of the coffee due to aging, decaffeination, and oxidation.
