Vacuumed coffee packets:
Can be kept unopened for up to 14 months after packing.
Store in a cool and dark place.
Once open, the coffee should be consumed within 2 to 3 weeks and preferably stored well-sealed in a refrigerator. After this period the coffee is still enjoyable but loses its optimum quality and taste.
Coffee loses its aroma faster when it is ground, therefore it is advisable to buy ground coffee in small amounts and to consume it within 2 -3 weeks.
Never fill your coffee machine with too many beans as a constant warming-up of the product will affect the quality. Heat causes the roasted bean to sweat slightly and can give a rancid taste to the coffee.
So, fill the machine sparingly, seal the packet well and store it in your refrigerator.
