Q- Should I refrigerate my bottle of Amarula Cream after opening, and how long will it remain fresh?
A- Stored under the proper conditions a bottle of Amarula Cream (opened or unopened) should be good for approximately two years. We do recommend that you store unopened bottles in a cool, dry place away from direct light, and that you refrigerate Amarula Cream after you have opened the bottle.

Q- How is Amarula Cream made?
A- Amarula Cream is made from the fruit of the Marula Tree that only grows wild, in the warm, frost-free regions of subequatorial Africa. Marula trees cannot be cultivated, and the fruit has to be picked when the fruit ripens during the height of the South African summer, mid-January to mid-March. The fruit is then distilled into liquor that is then added to the highest-quality cream to make Amarula Cream.
