In general, pineapples harvested in the winter tend to be more acidic and have a lower sugar content than does fruit harvested in the summer. (Of course, keep in mind that when it’s winter in the northern hemisphere, it’s summer in the southern half — so the source of your pineapple matters.)
The 10 countries that grow the most pineapple: Costa Rica, Philippines, Brazil, Thailand, India, Indonesia, Nigeria, China, Colombia and Mexico.
You can keep pineapple in the refrigerator for two to four days — and cut pineapple should be kept in the fridge in a tightly-covered container. However, the Del Monte company also points out that since a pineapple won’t ripen any more after picking, try to eat it as soon as possible.
